How to install a metal tile roof. Installation of metal tiles with your own hands. We take care of long-term service - we provide ventilation and waterproofing

Construction is not a cheap industry. And, as you know, there is never too much money, so you can save on labor force, i.e. do everything yourself.

Before starting installation work, you should:

firstly, determine the amount of financial costs;
secondly, select the design of the future roof;
thirdly, carefully study the technological process.

How much does it cost to cover a roof?

Whatever the design of the roof, its cost is made up of four items:

frame;
insulators;
upper roofing material;
wages of workers (in our case this cost item is absent).

The first and easiest way to determine the cost of your roof is to call local companies and ask the manager about the prices for installing a metal roof, after first calculating the area of your roof. Many employees will be happy to provide approximate prices. The second option (calculate everything yourself) is more difficult, but no less accurate and reliable.

Volume calculation

Frame – wooden structure, consisting of main and auxiliary fragments. The first are the mauerlat, rafters, sheathing; the second - tightening, racks, struts. All together they make up rafter system roofs.

There is a good online calculator on the Internet, with which you can calculate the volume of lumber, effective loads, see the rafter layout diagram, etc.

But there is one caveat - the calculation is carried out not for all types of roofs, but for single-pitched, gable, mansard (including sloping roofs) and hip ones. That is, if you have more than four slopes, then you will have to count manually. After we have determined the number of boards and timber, we select insulating materials for the metal roof.

Insulating materials

Insulators for roofing works the following will be required: steam-waterproofing and thermal insulation.

Metal tiles retain the bulk of atmospheric moisture, but vapors contained in the outside air still get inside. To protect the underlying structural layers, steam and waterproofing is used. The difference between vapor barrier and waterproofing is that the first is aimed at passing vapors from inside the room to the outside, and the second is aimed at preventing external moisture from penetrating into the roof structure. Film vapor and waterproofing insulators combine the functions of both layers and are either perforated or non-perforated. On the packaging of such roll material, after the name, a number is indicated; it indicates the weight of 1 m2 of film.

In addition to common film insulation, builders also use special polyethylene materials, with inside reinforced aluminum foil. Such films are rarely used for residential buildings; they are usually laid during the construction of baths, saunas, and swimming pools.

The best sellers on the moisture-proof film market are Izopsan, KLØBER, TechnoNIKOL, and DUPONT, but there are also cheaper analogues.

Enclosing material

As mentioned above, the main protective function is performed by the top roofing layer - metal tiles, which are sheets of thin sheet steel (galvanized), aluminum or copper, coated polymer layer and cold deformed. Visually, metal tiles are very similar to ordinary tiles, but they weigh much less - 5 kg/m2, and this is not its only advantage.

We can also name the tangible advantages of a roof under metal tiles:

durability (15 – 20 years);
aesthetic appearance;
ease of installation and repair during operation.

Beauty, of course, is important, but quality characteristics play a decisive role. It is worth paying attention to:

a steel base containing the necessary alloying elements that improve the strength and rolling properties of the metal;
class and type of protective coating;
class and type of protective and decorative polymer coating.

The optimal thickness of the steel sheet is from 0.45 to 0.5 mm. With a smaller thickness, difficulties arise in installing a roof made of metal tiles: deflections, breaks and other deformations. The protective base of the metal coating in the production of metal tiles is:

zinc;
zinc-aluminum;
aluminum-zinc;
aluminum-silicon;
iron-zinc.

Zinc consumption during production is 225-275 g/m2.

It is used as a protective and decorative layer in the production of metal tiles. the following types coatings:

polyester (PE);
polyurethane (Pural);
polyvinylidene fluoride;
acrylate;
plastisol.

For use in an urban environment (except for cases where factories that emit aggressive substances into the environment are located nearby), a polyester coating with a thickness of 25 to 30 microns is optimal. The above coatings “in their pure form” are not used. Foreign and domestic companies apply complex compositions of copolymers with various additives. The recipe for such coatings is kept in the strictest confidence.

In addition to the metal tile itself, additional elements will be required for roof installation: valleys, ridge caps, external and internal corner strips, ridge and connecting strips, seam strips; as well as fasteners: studs, self-tapping screws, nails, etc.

After purchasing all necessary materials Let's start construction.

Metal roofing installation technology

DIY roofing tool

To make a roof with your own hands you will need the following tools:

ladder;
metal scissors;
screwdriver and electric drill;
long rail;
mounting tape;
hammer;
marker;
level and tape measure (preferably metal);
low hardness brush;
mallet with rubber head;
hand-held circular saw.

Remember: under no circumstances should metal tiles be cut with a grinder! This can lead to damage to the polymer protective coating, after which corrosion of the base metal will begin to form during operation.

Step-by-step instructions for installation work

The beginning of all work is the installation of the rafter system, carried out in several stages. Installation instructions for both cold and warm roof made of metal tiles can be included in the following installation scheme:

Step 1. Waterproofing the walls

The first step is to waterproof the walls. This can be done using ordinary roofing felt. Timber is laid on the walls from pediment to pediment along the entire length. Afterwards, we check the horizontality of the structures with a level and control the pitch of laying the timber. The Mauerlat is secured with anchor bolts into pre-drilled vertical holes in the beams. Later they begin to install rafter legs to it.

Step 2. Installation of purlins

Installation of purlins helps to simplify the work, since it becomes possible to fasten each pair of rafters separately. The purlin is placed in the highest positions of the front walls and secured in the designed position with anchors or steel corners. The ends of the purlins are also waterproofed.

Step 3. Attaching the rafters

Before you begin attaching the rafters to the already assembled frame elements, you should lay out all the rafter boards in the strict sequence of their further installation. We must label all elements to avoid confusion.

We trim the rafter legs and precisely adjust all the gaps and angles. In the upper section, the rafters are connected with overlays. Each joint must have a minimum of 5 nails. First, the outer rafter sections are installed, and then those between them, distributing them along the entire length of the house. At the bottom of the rafters, tie downs are installed. All structures must be verified during installation.

Step 4. Installation work

After installation, alignment and final fastening of the rafter system, we begin the roofing installation work. In order for the roof to serve for a long time, and the metal tiles to reliably protect from precipitation, the installation of all fragments is carried out in strict technological sequence, which includes the following steps:

installation of counter rails;
laying waterproofing;
fastening elements of vertical sheathing;
installation of the initial bars of the horizontal sheathing;
additional lathing;
installation of wind boards;
installation of brackets for drainage gutters;
cornice strips;
installation of metal tiles;
roof ridge and its seal;
thermal insulation works;
vapor barrier;
attic filing (for attic roofing).

If the roof is cold, then the last three stages are not taken into account.

Metal tiles are suitable for roofs with slopes of at least 14°. The pitch of the transverse wave of metal tiles directly affects the spacing of the sheathing battens. So, with a transverse wave with a range of 300, 350 and 400 mm, the sheathing pitch will be 300, 350 and 400 mm, respectively. The distance between the lowest lath of the sheathing and the one next to it is respectively 230, 280 and 330 mm. The fragments of the sheathing themselves must be subjected to antiseptic treatment.

Continuous sheathing is installed in the places where chimneys pass, at the location of the valleys. Before you begin fastening the metal tiles, be sure to secure the lower valley strips along the continuous sheathing. The overlap of one part onto another is about 100-150 mm. The tiles are installed from bottom to top. The joining areas of metal tile sheets are additionally covered with decorative inserts - upper valley strips.

Remember: junction nodes are the most vulnerable places, so their arrangement is approached with increased attention. They use sealants for external work, seals, and an additional layer of waterproofing.

Another extremely important aspect when installing a metal tile roof yourself - fasteners. Purchase a set of fasteners and metal tiles together from the supplier, otherwise you may lose your warranty rights to the purchased product.

Safety precautions

Construction and installation works – dangerous look activities. Perform all sawing, cutting, drilling, and fastening operations in protective clothing, gloves, and protective masks or goggles. When working for a long time, your hands become sweaty, tools can slip out, damage your fingers and cause infection. Wearing masks and goggles will help protect your eyes from metal dust and your respiratory tract from micro-pellets of insulation. For which rolled mineral wool materials are used.

Compliance with safety rules is the key to your health.

Metal tiles are a material that is used for roofing along with such popular materials as slate, bitumen shingles and galvanized sheet. Excellent technical characteristics make it excellent options for any home. And although they usually prefer to invite professionals to carry out this kind of work, let’s look at how to install metal tiles yourself: step-by-step instructions and some recommendations from specialists.

A tile roof, especially if it is made of metal, is one of best options for home decoration. Experts and users themselves note many positive aspects of using this material, including:

light weight (4-6 kg/m²), which ensures very little load on the roof;

It is distinguished by an affordable price, long service life and expressive appearance.

simple installation procedure and ease of implementation repair work;
large assortment color solutions;
the material is environmentally friendly and does not contain any harmful components;
the coating is equipped with stiffening ribs, which makes it very durable. Provided that all installation recommendations are followed, the surface can withstand a load of 200 kg/m², even if 0.5 mm thick sheets were used;
the material is extremely temperature resistant. It is not afraid of any changes, and the rate of thermal expansion is minimal.

There is practically no need to talk about the disadvantages of metal tiles, with the possible exception of higher level noise on days when it rains. But this can also be dealt with if you first lay a layer of glass wool.

Criteria for choosing a material for a metal roof: photo examples

Before you begin considering the installation process of this roofing material, you need to decide exactly how the material should be used.

Viewing photos of roofs on which metal tiles look attractive is far from best method V in this case, since in the selection process you need to pay attention to the list of additional elements, as well as the markings provided by the manufacturer. Let's look at what the buyer needs to know.

First of all, you need to pay attention to the presence in the price list of such additional elements as:

different types of skates: simple, figured and with aerators;
special passage units for installing pipes, hatches, ventilation, antennas, as well as lighting windows;
elements designed to ensure the safety of surface maintenance - walking bridges, ladders, snow guards;
internal and external valleys;
other necessary elements– wall profiles, pediments, eaves strips of metal tiles, the installation of which is an obligatory part of the roofing arrangement.

Important! The presence of all of the listed elements among the seller’s offers is an indicator of the level of the company that produces metal tiles, which may also indicate the quality of the products themselves.

In addition, it is worth paying attention to studying the markings, which must be present on each certified material. Typically, production indicates all the characteristics of the material itself, as well as the level of quality of the anti-corrosion coating that is applied on top of the sheet.

So, here is what information you can glean by reading the information provided on the back of the metal tile sheet:

presence of polymers;
how much zinc is per 1 m² of sheet;
production date and warranty period for the use of the material;
manufacturer's name;
sheet thickness.

During the visual inspection, you need to pay attention to the integrity of the protective layer, both on the front and back sides of the sheet, as well as the presence of all required markings.

Important! If we are talking about material purchased from a large manufacturer, then the marking will also contain information about the grade of steel used.

Installation of metal tiles: step-by-step instructions for independent work

Considering the fact that the price of installing metal tiles has never been low, many people prefer to try to do everything they need on their own. Although initially it is worth familiarizing yourself with how much it costs professional installation metal tiles. The price of work per m2 starts from 250 rubles and can increase depending on the complexity.

The process of installing a metal tile roof, the technology of which will be discussed below, consists of several stages, each of which has its own significance and must be carried out properly.

Laying metal tiles: preparatory stage and calculations

The first thing you need to do if you have decided to independently carry out the procedure for laying metal tiles on the roof surface is to carry out preliminary calculations. This is necessary in order to determine how much of what materials will be required and, accordingly, avoid unnecessary costs.

Let's start by clarifying some basic concepts so that in the future the question of how exactly a metal tile roof is constructed does not arise. If you look at a roof that has already been covered with this material, you can see that it consists of rows that run across the slope and waves. The distance from one row to another is called a step.

There is such a thing as a “model”. This name refers to sheets of metal tiles, the pitch of which is 35 cm, and the number of waves is 6. Sheets of modules 1, 3, 6 and 10 can be found on sale.

Useful advice! In addition to purchasing sheets standard sizes, you can consider the option custom made metal tiles to order. Of course, it will cost significantly more, but this way you can get exactly the material that is right for you. The main thing to remember is that the length of one sheet should not be less than 45 cm or more than 7 m.

During the selection process suitable size The sheet should be guided by the fact that after installation the joints and waves converge in such a way as to form a single coating along the entire length of the slope. It is quite easy to calculate the amount of material, taking into account the length of the roof and sheets.

When purchasing metal tiles, it is important to pay attention to some additional elements that are included in the kit and allow you to correct installation. This includes steel strips 2 m long, as well as steel sheets 200x125 cm, which should have the same color as the tiles.

In the process of purchasing metal tiles, you need to make sure that these auxiliary elements are available in sufficient quantity and meet all requirements. For example, the standard bar inclination level is 30 degrees. Although other options are possible at the request of buyers - from 11 to 70 degrees.

Important! 11 degrees is minimum slope, in which installation of metal tiles is permissible.

Materials and tools for laying metal tiles with your own hands

In order to install metal tiles with your own hands, you need to take care in advance of having some tools and materials that will allow you to carry out all the work as simply and efficiently as possible:

screwdriver;
electric drill;
scissors for cutting metal;
measuring tape;
hammer;
marker;
mounting tape.

It is also worth taking care of the presence of a stepladder and means intended for personal protection face and hands (glasses, gloves).

As for consumables, which will be required to prepare the base and fasten the metal tiles, then this list includes: waterproofing material, roofing strips, tiles, as well as an aeroroller, strips for the ridge and ends, a guide board and 2.5x10 cm boards. Of course, fasteners will also be required elements - self-tapping screws and special sealing washers for them.

Useful advice! To give the coating an attractive appearance, decorative overlays should be used.

How to attach metal tiles: stages of preparatory work

The low weight of metal tiles allows for a minimum amount of preparatory work, before proceeding with installation. Nevertheless, it is still necessary to prepare a suitable foundation. Since there is no need for a reinforced base, an ordinary wooden one made from slats is quite suitable.

The procedure is extremely simple - based on the pitch of the selected metal tile, slats are placed on the surface. It is important to maintain a uniform distance so that when attaching the roofing material you do not have to screw screws into the void. Another important factor One thing that should be taken into account during the installation of the sheathing is the location of the windows. It is highly undesirable to place rafters directly above the windows.

Thermal insulation during installation of a metal roof

When it comes to installing a roof made of metal tiles, the thermal insulation material is designed to solve two problems at once - to reduce heat loss, and also to reduce the noise level produced by raindrops hitting the surface. To do this, first lay on the rafters vapor barrier material, and then a layer of thermal insulation. In this case, it is important that the thickness of the layer does not exceed 25 cm. An antioxidant film is attached to the top, fixing it with wooden blocks directly to the rafters.

Important! In order to ensure that precipitation flows into the drain, the material must be fixed with a small allowance (about 2 cm). Due to such a small sagging there will be no problems with water drainage.

This “pie” is the maximum efficient system thermal insulation of the roof, which is allowed by the metal tile installation technology. As for the choice of thermal insulation material, there are several options that depend on cost, quality and manufacturer.

Installation of a metal tile roof: basic operating rules

Before you begin work directly related to laying metal tiles, you need to familiarize yourself with some rules and concepts that will allow you to avoid common mistakes and do everything necessary with the highest possible quality:

There are two ways to lay sheets of metal tiles: from right to left and from left to right. In the first case, each subsequent sheet must be laid overlapping the previous one, and in the second, the previous sheet must be overlapped.
There is no need to attach each sheet completely at once. Before screwing the metal tiles, it is best to lay four sheets and lightly grab them with fasteners so that they hold. Then you need to make sure that they are located as needed and, if necessary, trim them. For final fastening, use one self-tapping screw that passes through all the sheets.
The service life of the entire roof greatly depends on the quality of the fasteners used. Therefore, due attention should be paid to the choice of self-tapping screws. It is important that they are galvanized and must have special seals on the heads that can hermetically fill the holes when the self-tapping screw is completely screwed into the hole.
In those places where several sheets were fastened with one fastener at once, one way or another, a seal will appear. In order to smooth it, it is necessary to cut off part of the corner, or you can straighten the capillary groove, which is located under the stamping line.

Scheme of fastening metal tiles and other necessary elements

Certain rules also exist for the installation of other mandatory elements, without which no roof can do. Here are some recommendations regarding the installation scheme of metal tiles and other elements:

the end strips must be fixed with an overlap, which should be about 2 cm. In this case, the size of the wave must be adjusted in accordance with the width of the slope. Otherwise, you may encounter the fact that the ridge will fit onto the pediment;
for the cornice strip it is also necessary to have an overlap of 10 cm on the bottom bar of the sheathing, to which it is attached with nails;
It is imperative to lay an additional layer of sealing material between the metal tile sheet and the roofing strip;
for the arrangement of all elements located below the ridge (pipes and windows), sheets with one module are used. Typically, 2 pieces are required for each structural element;
if the roof slope is sloping, then it is necessary to additionally install an aeroroller between the ridge strip and the material itself. This will prevent penetration under the ridge. atmospheric precipitation;

The ridge must be fixed to the planks, which are located at the end of the entire structure. In this case, calculations must be carried out taking into account the required protrusion, which is 2-3 cm. Moreover, if you have to deal with a flat ridge, then the fastening is done with an overlap, and for semicircular elements according to the profile lines;
It is necessary to study in advance the specifics of installing a drip line under metal tiles, and strictly follow all instructions.

Useful advice! If you have to work with a roof whose inclination angle is more than 45 degrees, then it is worth carrying out calculations in advance that will allow you to determine whether it is possible to install a specific model of ridge strip in this case. This must be done, because otherwise, you may even need complete replacement the entire roof covering.

It is also worth paying attention to the fact that, if necessary, the ridge strip can be slightly adjusted. That is, it can not be bent or straightened to ensure the most accurate repetition of the angle of the roof. You can learn more about such subtleties from the video instructions for installing metal tiles.

Installation of a valley when roofing with metal tiles

Another extremely important element, the installation rules of which cannot be neglected, is the valley. For each such element, an additional board must be attached. In this case, fastening must begin from the bottom, gradually moving upward and not forgetting about the need for overlap (in this case, 25-30 cm). Below the level of the cornice, be sure to cut off the bottom strip. Then follows the flanging, under which, like under the ridge, a seal is laid.

There remains a gap between the sheets and the axis, about 8-10 cm in size. Then, at a distance of approximately 1.5 cm from the stamping line, screws are screwed into the cut sheets. In this case, the fastening should be located 25 cm from the valley axis. If you follow this technology, then eventually the sheet, at the fastening point, will converge with the board on which the valley is located.

As for the installation of the valley below, it must begin before laying the roofing material. This is important to ensure that water flows directly into the additional element in the future.

Important! All errors in the process of calculations and measurements can lead to the appearance of gaps on the surface, and when heavy precipitation begins, the roof will most likely leak.

In order to cover those places where the cut sheets are visible, special decorative overlays are used. When installing them, you also need to remember a few simple rules:

installation must be done from the bottom up;
a sealant between the lining and the tile is not needed;
the overlays must be overlapped by at least 10 cm;
fastening elements (in this case self-tapping screws) should not cause damage to the valley.

Very often you have to deal with situations where the beginning and end of the valleys are located directly on the roof slope. As an example, we can consider the case when a dormer window is installed. In such a situation, it is necessary to lay a separate board, and for the window itself, a hole is made in the metal tile sheet. The cornice cut is covered with a plank. And sealing material must be laid along the walls.

How to lay metal tiles on a roof with a triangular or trapezoidal slope

If there is a need to cover a triangular or trapezoidal roof with metal tiles, then the installation of two additional bars will be required. They are installed along the fold line of the roof on both sides of the “ridge”. After this, the cornice board is mounted and the assembly of the sheathing begins. The pitch of the sheathing for metal tiles in this case is calculated in the same way as with standard scheme. Then the cornice system is installed. They begin to lay the metal tiles only after all these procedures have been carried out, orienting and aligning the first sheet along the eaves strip.

Important! The distance between the corner sheets that were trimmed and installed near the “ridge” should not exceed 10 cm.

In order to install the ridge knots you need to align ridge strips relative to the angle of the "ridge". If you use a straight ridge, it must be cut according to the existing corners, and for a semicircular ridge special plugs are provided. Moreover, it is best to use plastic models.

The ridge strip must be located strictly along the axis of the “ridge”. It's not too much difficult task, if the slope angles are the same. If they have different sizes, then the task becomes significantly more complicated. As auxiliary material use bright polyurethane foam, which allows you to determine the quality of the connection to the slopes.

Installation instructions for metal tiles "Monterrey"

A separate type of metal tile that is undoubtedly worthy of attention is Monterrey. This option is very popular due to some exceptional characteristics:

extremely high level resistance of the material to both ultraviolet radiation and other external factors, such as moisture and temperature;
due to the layer of polymer applied to the surface of the tile, it does not lose its appearance throughout its entire service life;
the material is extremely durable and hard, so it can withstand heavy loads;
multilayer structure prevents corrosion;
due to its low weight (one square meter material weighs no more than 5 kg), the load on the rafter system is significantly reduced;
using this option is a great savings, since there is no need to take a large step between fasteners. Initially, the installation instructions for Monterrey metal tiles provide for 35-centimeter steps.

This material has only two disadvantages - a large amount of residue after installation, as well as the need for high-quality sound insulation.

As for the features that you need to know about before laying Montrerey metal tiles, the following aspects play a role here:

For different models of this material, it is necessary to prepare different lathing. So, for Standard or Super metal tiles, a step of 35 cm will be enough, but for Lux or Maxi, the step should be 40 cm;
in the most difficult places on the roof (usually internal corners, as well as the place where the chimney outlet is located), you need to make a continuous sheathing;
on the junction strips, for the chimney exit, you need to install internal aprons;
the installation instructions for Monterrey metal tiles do not provide for the use of material whose length is more than 4 m;
Before installing the material must be removed protective coating, since this may not be possible in the future.

It is strictly forbidden to cut the sheet in the transverse direction, as this may lead to the profile becoming wrinkled. Also, under no circumstances should you use a grinder or other tools with abrasive wheels for this purpose.

Interesting! Cascade metal tiles also look great, the installation instructions for which are not too different from all the others. But the appearance of such a roof is considered more aesthetic and original.

How to properly care for a metal roof covering

Having studied step by step instructions installation of metal siding, you can carry out its high-quality installation. But in order for the material to last for many years, you need to know how to care for it.

The top layer of metal tiles is polymer material, which is designed to protect against corrosive processes. But as a result of constant exposure to external factors: precipitation, ultraviolet rays, as well as dust and dirt, this layer may begin to deteriorate, which will lead to the need to replace the coating. In order to avoid similar phenomenon and extend the service life of the roof, it is necessary to regularly carry out the following procedures:

remove dirt, dust and dry leaves from the surface using a damp fluffy brush;
If we are talking about eliminating more complex stains, then it is permissible to use cleaning products, but only those intended for polymer surfaces. Use aggressive chemicals it is strictly prohibited, as they destroy the protective layer and render the material unusable;
cleaning of gutters is carried out using a stream of water, which should be directed from the ridge to the eaves;
It is possible and necessary to clear snow, but this should only be done using tools that are not capable of damaging the delicate coating.

Subject to these simple but extremely important rules, metal roofing can serve as a roofing material for about 50 years.

Common mistakes when installing a metal tile roof with your own hands

Inexperienced craftsmen often make mistakes, which can lead to the fact that the work will have to be partially, and sometimes completely, redone. Such carelessness can lead to additional expenses for the purchase of materials and consumables, so it is better to familiarize yourself with common mistakes in advance in order to prevent them:

installation of metal tiles should be carried out exclusively in shoes with soft soles that cannot damage or scratch the coating;
It is strictly forbidden to step on the crest of a wave, as this may cause deformation;
Moreover, it is generally not recommended to step on the sheets with a full foot;
when moving along the surface of the material, the leg should be placed parallel, and not perpendicular to the slope;
You can only handle the material while wearing gloves.

Taking these simple rules into account, as well as acting in accordance with the technology for laying metal tiles, you can make a beautiful and reliable roof yourself.

Installation of snow guards on metal tiles: instructions and their varieties

A high level of safety is one of the main requirements for roofing made of any material, including metal tiles. For this purpose, special structures are used, which are called snow retainers. And the main goal is to ensure safe snow removal from the roof and prevent possible dangerous situations. In addition, they help maintain the original shape of the structure and prevent it from deforming under the weight of icy snow. And considering that its weight in some cases can exceed the weight of the roof itself, this problem is quite relevant.

Important! The issue of distributing the load that snow exerts on the roof surface should be thought out at the stage of laying the foundation. This factor must be taken into account in the calculations.

It is almost impossible to predict exactly how snow will be distributed on the roof surface. This depends on many factors, including the angle of the roof, wind direction, etc. Therefore, in order to make calculations, a special formula is used:

Q = G×s

In this case, Q is the load exerted by the snow, G is the mass of snow on the flat surface of the roof, which can be found from a special table, and S is the correction factor, which depends on the angle of the roof: > 25° - 1, if 25- 60° - 0.7. If the degree of inclination is more than 60, then this is not taken into account, since in this case precipitation will definitely not linger on the surface.

In order to determine the G index, you need to refer to a special table that provides information regarding snow cover for each region of the country.

Installation of tubular snow guards on metal tiles: installation rules

As a rule, a pipe is used as a basis for snow retention, which is laid along the roof. In the case of using metal tiles as a roofing material, fixation is made in the places where the roof and load-bearing wall connect.

It is strictly prohibited to fix these elements on the eaves strip for metal tiles, as this may lead to the destruction of the entire system. Moreover, if you have to deal with a slope whose length is quite large, then the installation of snow retainers on metal tiles must be done in several rows at once to ensure a more reliable fixation.

The tubes themselves are mounted on the roof either end-to-end or in a checkerboard pattern. Special attention should be paid to installing such a system if the house has an attic. In this case, the installation must be carried out in such a way that a snow guard is located above each window opening. As for the distance from the edge of the roof to the elements, 40-50 cm is quite enough.

Lattice snow retainers for metal roofing: how to attach correctly

Lattice snow retainers are considered the most effective, so those users who are interested in the quality of the installed systems preferentially choose this option. There are two types of such structures - ordinary and “royal”, although it is worth recognizing that there is not much difference between them, with the exception of the supports and the complexity of the lattice.

The high level of efficiency and safety of this type of snow retainer is due to their considerable height, due to which they may not be useful not only in winter when it comes to retaining snow, but also in summer. After all, it is in warm time Every year, all kinds of repair work are most often carried out.

Corner snow retainers for metal tiles

Corner snow guards are thin steel sheets that are coated with a polymer coating that protects them from corrosion. This is one of the most budget options, which at the same time allows you to effectively prevent snow from rolling off the roof. It is very easy to choose a model that will suit your existing metal tiles, since the range of color options is extremely large.

To fix the corner snow guards on the roof of a metal tile roof, use self-tapping screws and ordinary metal corners. Fastening is carried out on the upper wave of the sheet.

These are not all design options that can be used to prevent snow from rolling off the roof. Metal tiles are perfectly combined with many models and varieties of these elements, so there will definitely not be any problems with selection and fixation.

Installation of a roof window in metal tiles

It is believed that installing roof windows is not a task for beginners, and it is best to contact specialists who have adequate experience in this field. But this does not mean that it is impossible to do it yourself, especially if you use step-by-step instructions for dummies. The installation of metal tiles and the installation of the window itself in this case may well proceed without any problems.

First of all, it is worth paying attention to the fact that the maximum possible width of such a window should be 80-120 mm less than the opening between the rafters. In cases where rafter step very small, they install two small windows in adjacent niches.

The installation of the window is carried out after the roofing “pie” is completely made, then you need to install the mounting beam, for which I use the same boards as for the rafter system. Then the frame is installed and the sashes are installed. It is very important to take care of high-quality waterproofing so that in the future the window does not become a source of precipitation entering the house.

Of course, you have to make some changes to the process of installing the sheathing under the metal tiles, and pay special attention to the issue of installing the ridge of the metal tiles if you plan dormer window. But all these difficulties are more than justified by the excellent result that awaits the owners as a result.

Installation of metal tiles: video instructions for beginners

For those who have never done such work before, it will be extremely useful to watch a video on how to attach metal tiles to a roof. A visual demonstration, as well as recommendations from specialists, will allow you to avoid mistakes and make a beautiful and reliable roof, which will serve well for many years.

Metal tiles are one of the most popular roofing materials among owners of country houses. In addition to excellent performance characteristics, it has another important advantage - ease of installation. You can cover the roof with roofing sheets of this type yourself.

What tools and materials will you need?

Screwdriver and hammer;
Electric hacksaws and scissors;
Long staff and marker.

An electric hacksaw is needed for cutting rafters and boards. Using metal scissors, metal tiles are cut.

You cannot cut this material with a grinder. Otherwise, due to damage to the top layer by sparks, the sheets will not last long and you will have to repair the roof with reinstallation of the roofing material.

From the materials you will need to prepare:

Beam for rafters 50x150 mm;
Beam for Mauerlat 150x150 mm;
Lathing board 25x100 mm;
30x50 mm batten for counter-lattice;
Waterproofing membrane;
Mineral wool;
Consumables.

The cross-section of lumber must be maintained. Otherwise, the owners of the house will soon have to repair the roof or even reinstall it after assembly.

In addition to the metal tiles themselves, you will need to purchase various types of additional elements: cornice and end strips, valleys, ridge element, chimney apron, snow retainers, etc.

Additional elements for metal tiles

How much does a metal roofing cost?

The cost of a roof made of this material depends on several factors:

Type of polymer coating material;
Difficulty in roof configuration;
Type of insulation used;
Roof size.

On average, 1 m2 of metal roofing costs approximately 1,000 rubles. Therefore, making a preliminary rough calculation will not be difficult. To do this, the roof area in square meters should simply be multiplied by 1000.

Features of constructing a roof made of metal tiles

Of course, install this material on installed frame should be correct. This applies to both the assembly of the rafter system and the cutting and installation of the sheets themselves. There will be no need to repair the roof for a long time even if it is properly covered with waterproofing.

Preparatory work

The construction of a rafter system begins with measuring all the walls and eliminating discrepancies in their dimensions. The smoother the structural elements of the house frame are, the less effort will subsequently have to be spent on adjusting the rafter legs. Before starting work on assembling the roof, all lumber must be dried under a canopy for several months. The Mauerlat is installed first, and then the beams for the floor.

Material measurements

In order to draw up a roof plan, various types of measurements should be taken. For example, all the videos available on this topic on the Internet present this process like this:

First of all, measure the exact length of all the walls of the box. Based on this, the area of the slopes is determined;
Determine where the chimney, ventilation holes, roof windows, etc. will be located.

In accordance with the results obtained, the sheets and timber are then calculated.

Lumber calculation

After the roof project has been drawn up, you can begin to perform calculations necessary lumber. Their number depends primarily on the angle of inclination of the slopes and the area of the roof. Most often it is arranged under metal tiles gable roof with a slope of 30–35 degrees.

The amount of timber for the rafter legs is determined depending on the step at which they are going to be installed, the height of the roof and its dimensions.

The length of one leg is calculated by the formula c = √(v2 + m2), where v is the height of the roof, and m is half the span length.

Step between rafter legs on a roof with a metal tile roof is usually 80–100 cm (depending on the width of the sheets). Make a calculation required quantity rafters can be done as follows:

Divide the length of the wall by the selected step;
Add one to the result and round up.

The rafter system for metal tiles does not require any additional reinforcement. The amount of material required for the sheathing is calculated based on the fact that the pitch between its elements should be 35–40 cm.

Assembling the rafter system

The roof frame is constructed using the following technology:

Mauerlat is fixed on the walls. It can be fixed with studs embedded in the masonry, or on anchor bolts, poured into the upper reinforcing belt;
Mount the rafters. The easiest way is to fix the legs on the support beam using corners (preferably galvanized ones, otherwise you will soon have to carry out roof repairs and replace them). The top of the rafters is most often cut at an appropriate angle and fastened in pairs using steel strips and crossbars.

Roof frame construction

On large areas and high roofs ridge beams are often used. In this case, the rafters are secured with planks above it and additionally pulled to it with corners. The ridge beam itself is mounted on racks fixed to the Mauerlat of the short walls of the house box.

Hydro- and thermal insulation device

Sometimes a cold roof is made from metal tiles. However, most often it is still insulated, as this significantly improves it performance characteristics. Wire or sparse plank sheathing is used as support for the heat insulator from the attic side. They insert cotton wool between the rafters at random. The top should be covered with waterproofing material, securing it with bars.

Waterproofing scheme

The strips are placed horizontally with an overlap of 15 cm. Do not stretch the film too tightly. Otherwise, when the rafter system moves due to shrinkage of the walls and wind, it may break. The sag of the film should be about 2 cm.

Roof sheathing

It is correct to assemble the base for metal tiles from fairly wide boards (at least 20 cm). Narrow material may warp under the influence of adverse weather factors. The sheathing is installed using a pole and a building level.

The distance between the first two sheathing boards from the bottom should be very small - 10–15 cm. The sheathing is arranged with the elements fastened to two nails to each rafter. In this way, you can assemble a reliable base for metal tile sheets.

How to correctly calculate metal tiles

After assembling the sheathing, you can install the roofing sheets themselves. But of course, you should first do exact calculation the required quantity. A video demonstrating the process of performing these operations is available on the Internet. You can, of course, look at it, but in principle there is nothing complicated in such a calculation. Perform this operation like this:

Calculate the area of each slope;
Calculate the number of sheets required to cover it, taking into account their width and length;
Add up the results obtained.

How to properly install cornice strips and lower valleys

The instructions for attaching these elements are simple. The cornice strip is installed before the sheets are installed. The frontal board is pre-stuffed. The gutter brackets are attached to it. Next, you can begin to actually attach the bar itself.

Installation of cornice strips

Another element that needs to be installed before covering the slopes with metal tiles is the lower protective valleys. Their installation is carried out in compliance with the following recommendations:

The sheathing under the valley must be continuous;
Installation of valley elements begins from the bottom up;
Each lower element should be overlapped with the upper one by at least 10 cm.

Choosing metal tiles

There are several types of metal tiles. When choosing this material, you should consider the following:

Only sheets made of steel with a thickness of at least 0.45 mm are considered reliable;
In central Russia, roofs are usually covered with inexpensive sheets with a polyester protective layer;
Warranty period for good material is at least 10–15 years. Home owners who buy this material will not have to pay for repairs if any problems arise.

Installation of sheets

So, now let's see how to cover a roof with metal tiles with your own hands. Installation of sheets begins from the bottom. When assembling the first row, arrange eaves overhang approximately 5 cm wide. Actually, the instructions for filing themselves look like this:

The first sheet is attached with one screw at the very top;
Then several more sheets (2–3) are attached to it along the side edge;
The entire pack is carefully leveled and secured to the roof frame.

Installation of additional elements

After all the slopes are sheathed, you can begin installing additional elements. First, the upper valley strips are attached. In this case, they perform mainly a purely decorative function. They are mounted on a self-expanding seal.

At the next stage, the end elements are fixed to the gables. Next, the ridge is installed. They fasten it in the same way as the upper valleys on the sealing tape.

Attic roof roof

Construction of the rafter system mansard roof done like this:

Racks are attached under the layered rafters, purlins and tie-downs;
The ridge is being installed. Its racks are secured in the middle of the puffs;
Layered and then hanging rafters are installed;
The sheathing is filled taking into account the characteristics of the roofing material.

Metal tiles are first sheathed on the sheathing of the layered rafters, and then on the hanging rafters. On the latter, in the same way as on the cornice, an overhang is made.

Some subtleties of installing metal tiles

The installation of sheets should be carried out by at least two people in compliance with the following recommendations:

The capillary grooves must be completely covered by the next sheets in the row;
All sheets must be carefully aligned parallel to the cornice.

We cover the roof: how to get around the chimney

Scheme of bypassing a pipe with metal tiles

The construction of a metal tile roof must be such that in the area where the material adjoins the chimney pipe, water does not leak into the under-roof space. To solve this problem, special aprons are used. The instructions for installing them are as follows:

Before laying the metal tiles around the pipe, it is packed continuous sheathing. A waterproofing material is glued onto it with an overlap of 15–20 cm over the pipe walls. A groove is made in the chimney itself along the entire perimeter.
After laying the metal tiles, the lower apron is installed first, and then the upper one. The bent edges of their vertical parts are inserted into the groove.

Subtleties of installing curtain rods

The cornice and end strips must be secured to the wood of the frame in increments of approximately 30 cm. If this condition is not met, they may subsequently come off, and unnecessary repairs will have to be made. It is highly not recommended to mount them end-to-end. Each subsequent plank must overlap the previous one by at least 1 cm. These elements are fastened with galvanized nails or self-tapping screws in a checkerboard pattern.

Installation of valleys: features

The lower valley should be secured with self-tapping screws into each purlin. Its overlap on the slopes should be at least 25 cm. In this case, there will be no need to repair the roof due to a rotten frame. The upper valley is mounted in such a way as not to damage the lower one. They attach it to the metal tiles either with special corners or with self-tapping screws at the top of the wave (in each).

Fastening sheets to roof breaks

Installation of roof breaks

As already mentioned, on attic sloping roofs, metal tiles are laid on the break with an overhang. Before installation, a drip strip (in increments of 30 cm) is usually mounted on the edges of the slopes of such a rafter system for reliability.

Sometimes there is another type of break in the roof configuration - with a negative angle. They close it in much the same way as valleys. In this case, the carpet is laid in such a width that top part it extended at least 35 cm onto the slope, and 15 cm onto the lower slope. The sheathing under it should also be solid.

Installation of snow guards

This additional element is mounted on flat roofs to avoid snow avalanches. The instructions for installing snow guards include the following steps:

Fastening is done long screws in the laths;
You need to make holes in the metal tiles and line them with rubber seals;
The brackets must be screwed correctly at a distance of at least 35 cm from the cornice.

Installation of lightning protection

Lightning protection scheme for a metal roof

This system must be assembled. If the lightning is attracted by the metal covering, you will have to carry out expensive roof repairs. And of course, natural electrical discharge is a very dangerous phenomenon for those living in the house. Lightning protection is assembled from the following elements:

Lightning rod, which is a rod with a length of 5 m;
Down conductor (circular wire);
Grounding conductor made of a metal strip with a thickness of at least 150 mm.

The lightning rod is fixed to the roof ridge. A wire is wrapped around the chimney and connected to the middle of the rod. The ground electrode is dug into the ground to a depth of at least 80 cm and connected to the lightning rod via a down conductor.

Safety precautions

When installing metal tile sheets, observe following rules security:

Cutting sheets and installing them on the roof is done using gloves;
Take the sheets by the edges from the sides;
To move along long slopes, special stairs are used;
People walk on the roof in soft shoes. In this case, there will be no need for early repairs due to damage to the coating.

Conclusion

As you can see, installing metal tiles is a relatively simple matter. Numerous videos and photos available on the Internet confirm this. The rafter system for this material may not be too powerful, since its weight is not particularly large. In this case, the rafters and sheathing are mounted using standard methods. When installing the sheets themselves, you should adhere to all required technologies: do not cut the material with a grinder and correctly fasten all additional elements. In this case, the roof will be reliable and its repair will not be required for as long as possible.
Detailed instructions for installing metal roofing are presented in the video.

Metal tiles are a material that is used for roofing along with such popular materials as slate, bituminous shingles and galvanized sheet. Excellent technical characteristics make it an excellent option for any home. And although they usually prefer to invite professionals to carry out this kind of work, let’s look at how to install metal tiles yourself: step-by-step instructions and some recommendations from specialists.

A tile roof, especially if it is made of metal, is one of the best options for decorating a home. Experts and users themselves note many positive aspects of using this material, including:

light weight (4-6 kg/m²), which ensures very little load on the roof;

It is distinguished by an affordable price, long service life and expressive appearance.

simple installation procedure and ease of repair work;
wide range of color solutions;
the material is environmentally friendly and does not contain any harmful components;
the coating is equipped with stiffening ribs, which makes it very durable. Provided that all installation recommendations are followed, the surface can withstand a load of 200 kg/m², even if 0.5 mm thick sheets were used;
the material is extremely temperature resistant. It is not afraid of any changes, and the rate of thermal expansion is minimal.

There is practically no need to talk about the disadvantages of metal tiles, with the possible exception of increased noise levels on days when it rains. But this can also be dealt with if you first lay a layer of glass wool.

Criteria for choosing a material for a metal roof: photo examples

Before you begin considering the installation process of this roofing material, you need to decide exactly how the material should be used.

Looking at photos of roofs on which metal tiles look attractive is far from the best method in this case, since in the selection process you need to pay attention to the list of additional elements, as well as the markings provided by the manufacturer. Let's look at what the buyer needs to know.

First of all, you need to pay attention to the presence in the price list of such additional elements as:

different types of skates: simple, figured and with aerators;
special passage units for installing pipes, hatches, ventilation, antennas, as well as lighting windows;
elements designed to ensure the safety of surface maintenance - walking bridges, ladders, snow guards;
internal and external valleys;
other necessary elements are wall profiles, pediments, metal tile eaves, the installation of which is an obligatory part of the roofing arrangement.

Important! The presence of all of the listed elements among the seller’s offers is an indicator of the level of the company that produces metal tiles, which may also indicate the quality of the products themselves.

So, here is what information you can glean by reading the information provided on the back of the metal tile sheet:

presence of polymers;
how much zinc is per 1 m² of sheet;
production date and warranty period for the use of the material;
manufacturer's name;
sheet thickness.

During the visual inspection, you need to pay attention to the integrity of the protective layer, both on the front and back sides of the sheet, as well as the presence of all required markings.

Important! If we are talking about material purchased from a large manufacturer, then the marking will also contain information about the grade of steel used.

Installation of metal tiles: step-by-step instructions for independent work

Considering the fact that the price of installing metal tiles has never been low, many people prefer to try to do everything they need on their own. Although initially it is worth familiarizing yourself with how much professional installation of metal tiles costs. The price of work per m2 starts from 250 rubles and can increase depending on the complexity.

The process of installing a metal tile roof, the technology of which will be discussed below, consists of several stages, each of which has its own significance and must be carried out properly.

Laying metal tiles: preparatory stage and calculations

The first thing that needs to be done if a decision has been made to independently carry out the procedure for laying metal tiles on the roof surface is to carry out preliminary calculations. This is necessary in order to determine how much of what materials will be required and, accordingly, avoid unnecessary costs.

There is such a thing as a “model”. This name refers to sheets of metal tiles, the pitch of which is 35 cm, and the number of waves is 6. Sheets of modules 1, 3, 6 and 10 can be found on sale.

Useful advice! In addition to purchasing sheets of standard sizes, you can consider the option of individually manufacturing metal tiles to order. Of course, it will cost significantly more, but this way you can get exactly the material that is right for you. The main thing to remember is that the length of one sheet should not be less than 45 cm or more than 7 m.

In the process of choosing the appropriate sheet size, you need to be guided by the fact that after installation the joints and waves converge in such a way as to form a single coating along the entire length of the slope. It is quite easy to calculate the amount of material, taking into account the length of the roof and sheets.

When purchasing metal tiles, it is important to pay attention to some additional elements that are included in the kit and allow for proper installation. This includes steel strips 2 m long, as well as steel sheets 200x125 cm, which must have the same color as the tiles.

Important! 11 degrees is the minimum slope at which metal tiles can be installed.

Materials and tools for laying metal tiles with your own hands

screwdriver;
electric drill;
scissors for cutting metal;
measuring tape;
hammer;
marker;
mounting tape.

It is also worth taking care of the presence of a stepladder and means intended for personal protection of the face and hands (goggles, gloves).

As for the consumables that will be required to prepare the base and fasten the metal tiles, this list includes: waterproofing material, roofing strips, tiles, as well as an aeroroller, strips for the ridge and ends, a guide board and 2.5x10 cm boards. itself, you will also need fastening elements - self-tapping screws and special sealing washers for them.

Useful advice! To give the coating an attractive appearance, decorative overlays should be used.

How to attach metal tiles: stages of preparatory work

The low weight of metal tiles allows for a minimum amount of preparatory work to be carried out before proceeding to installation. Nevertheless, it is still necessary to prepare a suitable foundation. Since there is no need for a reinforced base, an ordinary wooden one made from slats is quite suitable.

The procedure is extremely simple - based on the pitch of the selected metal tile, slats are placed on the surface. It is important to maintain a uniform distance so that when attaching the roofing material you do not have to screw screws into the void. Another important factor to consider when installing the sheathing is the location of the windows. It is highly undesirable to place rafters directly above the windows.

Thermal insulation during installation of a metal roof

When it comes to installing a roof made of metal tiles, the thermal insulation material is designed to solve two problems at once - to reduce heat loss, and also to reduce the noise level produced by raindrops hitting the surface. To do this, a vapor barrier material is first laid on the rafters, and then a layer of thermal insulation. In this case, it is important that the thickness of the layer does not exceed 25 cm. An antioxidant film is attached to the top, fixing it with wooden blocks directly to the rafters.

Important! In order to ensure that precipitation flows into the drain, the material must be fixed with a small allowance (about 2 cm). Due to such a small sagging there will be no problems with water drainage.

This “pie” is the most effective roof thermal insulation system that metal tile installation technology allows. As for the choice of thermal insulation material, there are several options that depend on cost, quality and manufacturer.

Installation of a metal tile roof: basic operating rules

There are two ways to lay sheets of metal tiles: from right to left and from left to right. In the first case, each subsequent sheet must be laid overlapping the previous one, and in the second, the previous sheet must be overlapped.
There is no need to attach each sheet completely at once. Before screwing the metal tiles, it is best to lay four sheets and lightly grab them with fasteners so that they hold. Then you need to make sure that they are located as needed and, if necessary, trim them. For final fastening, use one self-tapping screw that passes through all the sheets.
The service life of the entire roof greatly depends on the quality of the fasteners used. Therefore, due attention should be paid to the choice of self-tapping screws. It is important that they are galvanized and must have special seals on the heads that can hermetically fill the holes when the self-tapping screw is completely screwed into the hole.
In those places where several sheets were fastened with one fastener at once, one way or another, a seal will appear. In order to smooth it, it is necessary to cut off part of the corner, or you can straighten the capillary groove, which is located under the stamping line.

Scheme of fastening metal tiles and other necessary elements

the end strips must be fixed with an overlap, which should be about 2 cm. In this case, the size of the wave must be adjusted in accordance with the width of the slope. Otherwise, you may encounter the fact that the ridge will fit onto the pediment;
for the cornice strip it is also necessary to have an overlap of 10 cm on the bottom bar of the sheathing, to which it is attached with nails;
It is imperative to lay an additional layer of sealing material between the metal tile sheet and the roofing strip;
for the arrangement of all elements located below the ridge (pipes and windows), sheets with one module are used. Typically, 2 pieces are required for each structural element;
if the roof slope is sloping, then it is necessary to additionally install an aeroroller between the ridge strip and the material itself. This will prevent precipitation from penetrating under the ridge;

The ridge must be fixed to the planks, which are located at the end of the entire structure. In this case, calculations must be carried out taking into account the required protrusion, which is 2-3 cm. Moreover, if you have to deal with a flat ridge, then the fastening is done with an overlap, and for semicircular elements according to the profile lines;
It is necessary to study in advance the specifics of installing a drip line under metal tiles, and strictly follow all instructions.

Useful advice! If you have to work with a roof whose inclination angle is more than 45 degrees, then it is worth carrying out calculations in advance that will allow you to determine whether it is possible to install a specific model of ridge strip in this case. This must be done, because otherwise, you may even need to completely replace the entire roofing covering.

Installation of a valley when roofing with metal tiles

As for the installation of the valley below, it must begin before laying the roofing material. This is important to ensure that water flows directly into the additional element in the future.

Important! All errors in the process of calculations and measurements can lead to the appearance of gaps on the surface, and when heavy precipitation begins, the roof will most likely leak.

In order to cover those places where the cut sheets are visible, special decorative overlays are used. When installing them, you also need to remember a few simple rules:

installation must be done from the bottom up;
a sealant between the lining and the tile is not needed;
the overlays must be overlapped by at least 10 cm;
fastening elements (in this case self-tapping screws) should not cause damage to the valley.

How to lay metal tiles on a roof with a triangular or trapezoidal slope

If there is a need to cover a triangular or trapezoidal roof with metal tiles, then the installation of two additional bars will be required. They are installed along the fold line of the roof on both sides of the “ridge”. After this, the cornice board is mounted and the assembly of the sheathing begins. The sheathing pitch for metal tiles in this case is calculated in the same way as with the standard scheme. Then the cornice system is installed. They begin to lay the metal tiles only after all these procedures have been carried out, orienting and aligning the first sheet along the eaves strip.

Important! The distance between the corner sheets that were trimmed and installed near the “ridge” should not exceed 10 cm.

In order to install the ridge assemblies, you need to align the ridge strips relative to the angle of the “ridge”. If you use a straight ridge, it must be cut according to the existing corners, and for a semicircular ridge special plugs are provided. Moreover, it is best to use plastic models.

The ridge strip must be located strictly along the axis of the “ridge”. This is not too difficult a task if the slope angles are the same. If they have different sizes, then the task becomes significantly more complicated. Bright polyurethane foam is used as an auxiliary material, which allows you to determine the quality of the connection to the slopes.

Installation instructions for metal tiles "Monterrey"

A separate type of metal tile that is undoubtedly worthy of attention is Monterrey. This option is very popular due to some exceptional characteristics:

extremely high level of material resistance to both ultraviolet radiation and other external factors, such as moisture and temperature;
due to the layer of polymer applied to the surface of the tile, it does not lose its appearance throughout its entire service life;
the material is extremely durable and hard, so it can withstand heavy loads;
multilayer structure prevents corrosion;
due to its low weight (one square meter of material weighs no more than 5 kg), the load on the rafter system is significantly reduced;
using this option is a great savings, since there is no need to take a large step between fasteners. Initially, the installation instructions for Monterrey metal tiles provide for 35-centimeter steps.

This material has only two disadvantages - a large amount of residue after installation, as well as the need for high-quality sound insulation.

As for the features that you need to know about before laying Montrerey metal tiles, the following aspects play a role here:

For different models of this material, it is necessary to prepare different lathing. So, for Standard or Super metal tiles, a step of 35 cm will be enough, but for Lux or Maxi, the step should be 40 cm;
in the most difficult places of the roof (usually these are the internal corners, as well as the place where the chimney outlet is located), you need to make a continuous sheathing;
on the junction strips, for the chimney exit, you need to install internal aprons;
the installation instructions for Monterrey metal tiles do not provide for the use of material whose length is more than 4 m;
Before installing the material, it is necessary to remove the protective coating, since this may be impossible to do in the future.

Interesting! Cascade metal tiles also look great, the installation instructions for which are not too different from all the others. But the appearance of such a roof is considered more aesthetic and original.

How to properly care for a metal roof covering

After studying the step-by-step instructions for installing metal siding, you can carry out its high-quality installation. But in order for the material to last for many years, you need to know how to care for it.

The top layer of metal tiles is a polymer material that is designed to protect against corrosive processes. But as a result of constant exposure to external factors: precipitation, ultraviolet rays, as well as dust and dirt, this layer may begin to deteriorate, which will lead to the need to replace the coating. In order to avoid this phenomenon and extend the service life of the roof, it is necessary to regularly carry out the following procedures:

remove dirt, dust and dry leaves from the surface using a damp fluffy brush;
If we are talking about eliminating more complex stains, then it is permissible to use cleaning products, but only those intended for polymer surfaces. The use of aggressive chemicals is strictly prohibited, as they destroy the protective layer and render the material unusable;
cleaning of gutters is carried out using a stream of water, which should be directed from the ridge to the eaves;
It is possible and necessary to clear snow, but this should only be done using tools that are not capable of damaging the delicate coating.

Provided that these simple but extremely important rules are followed, metal roofing can serve as a roofing material for about 50 years.

Common mistakes when installing a metal tile roof with your own hands

installation of metal tiles should be carried out exclusively in shoes with soft soles that cannot damage or scratch the coating;
It is strictly forbidden to step on the crest of a wave, as this may cause deformation;
Moreover, it is generally not recommended to step on the sheets with a full foot;
when moving along the surface of the material, the leg should be placed parallel, and not perpendicular to the slope;
You can only handle the material while wearing gloves.

Taking these simple rules into account, as well as acting in accordance with the technology for laying metal tiles, you can make a beautiful and reliable roof yourself.

Installation of snow guards on metal tiles: instructions and their varieties

Important! The issue of distributing the load that snow exerts on the roof surface should be thought out at the stage of laying the foundation. This factor must be taken into account in the calculations.

Q = G×s

In order to determine the G index, you need to refer to a special table that provides information regarding snow cover for each region of the country.

Lattice snow retainers for metal roofing: how to attach correctly

The high level of efficiency and safety of this type of snow retainer is due to their considerable height, due to which they may not be useful not only in winter when it comes to retaining snow, but also in summer. After all, it is during the warm season that all kinds of repair work are most often carried out.

Corner snow retainers for metal tiles

Corner snow guards are thin steel sheets that are coated with a polymer coating that protects them from corrosion. This is one of the most budget-friendly options, which at the same time allows you to effectively prevent snow from rolling off the roof. It is very easy to choose a model that will suit your existing metal tiles, since the range of color options is extremely large.

To fix the corner snow guards on the roof of a metal tile roof, screws and ordinary metal corners are used. Fastening is carried out on the upper wave of the sheet.

Installation of a roof window in metal tiles

First of all, it is worth paying attention to the fact that the maximum possible width of such a window should be 80-120 mm less than the opening between the rafters. In cases where the rafter pitch is very small, two small windows are installed in adjacent niches.

Of course, it is necessary to make some changes to the process of installing the sheathing under the metal tiles, and pay special attention to the issue of installing the ridge of the metal tiles if a roof window is planned. But all these difficulties are more than justified by the excellent result that awaits the owners as a result.

Installation of metal tiles: video instructions for beginners

For those who have never done such work before, it will be extremely useful to watch a video on how to attach metal tiles to a roof. A visual demonstration, as well as recommendations from specialists, will allow you to avoid mistakes and independently make a beautiful and reliable roof that will serve well for many years.

Metal tiles are roofing materials in the form of profiled steel sheets coated with a polymer coating. It is used to cover roofs with an angle greater than 14 degrees.

Outwardly it looks like a classic ceramic tiles, but surpasses it in reliability and ease of installation. In this article we looked at which is better, ?

Material stable to temperature changes and other negative climatic influences. Its main disadvantage is low sound insulation characteristics, but it is eliminated when correct implementation works

In this article you will learn how to make a roof from metal tiles with your own hands, step by step from A to Z. If you don’t know how to choose metal tiles, then.

This stage of work should be given special attention, since it will be on the sheathing. This design also provides a natural interior roof space.

Metal tile sheathing is made from wooden beam . Mutual position boards can be solid or thinned.
Most often used sparse designs, while the distance between the boards () is strictly tied to the distance between the lower depressions of the tile waves, since in these places the material has the greatest strength.
Distance between the first two beams on the slope side there should be approximately 70 centimeters less than the established pitch.
The minimum thickness and width of the board for sheathing is 25 and 100 mm respectively.
The width of the board for the counter-lattice can be half as large. The first board from the edge of the roof should be 15-20 mm thicker than all the others.

PLEASE NOTE!

Pre-boards are calibrated one size at a time to avoid future distortions and unevenness in the location of the tiles.

Lathing step

Installation of the structure is carried out after completion . The main lathing is attached to the counter lath, which is connected to the rafter frame with self-tapping screws. At the ridge of the roof, additional support boards are laid under the metal tiles.

Calculation of metal tiles

Count the required amount of material for roof construction is done as follows (or use):

When counting the number of sheets in a row, you need to keep in mind the value overlap, which can reach 15-20 centimeters.

To ensure that there is no shortage of material, it is better to round all values up.

Roof calculation

Metal roofing: waterproofing and vapor barrier

Before you begin installing metal tiles with your own hands, you should take care isolation . Protection internal spaces from liquid provided with layers of vapor barrier and waterproofing.

The waterproofing is located between the rafters and the counter-lattice and prevents it from getting into the interior roofing pie moisture from environment. The most common waterproof materials– these are polyethylene and reinforced films. They are stretched over the entire area of the slope with slight sagging. It is important to ensure that the waterproofing does not overlap with the thermal insulation.

Roofing pie

Vapor barrier is a protective layer not letting in interior space roof moisture, formed in the premises. This is the lowest layer of the roofing pie; it is located under the rafters (to which it is attached) and thermal insulation, thereby ensuring its protection from condensation.

An attic roof made of metal tiles must be properly vapor-insulated; in cold roofs without insulation, installation of a vapor barrier is not necessary.

Required tools and equipment

Covering a roof with metal tiles begins with preparation necessary tools . To install a metal tile roof you will need:

Screwdriver.
Rail.
Tin snips or other metal cutting devices, e.g. nibblers, circular saw, etc.
Construction stapler.
Tape measure and marker.
Components of the roof and roofing pie: tile sheets, self-tapping screws, hydro-, steam- and heat-insulating materials, timber for sheathing and rafters.

PLEASE NOTE!

When working with tiles you can't use a grinder and other abrasives cutting tools, as this disrupts the structure of the sheet.

Fastening and laying metal tiles - step by step

How to cover a roof with metal tiles with your own hands? Self-tapping metal tiles with a gasket made of ethylene-propylene rubber, which provides waterproofing of the fastening areas.

If tiles are installed with hidden fastening, then galvanized self-tapping screws with a press washer are used.

Self-tapping screws must be tightened with optimal force.

If the fastening force is insufficient, then moisture will get under the cap and cause its corrosion. If you tighten the screws too tightly, the gasket will be deformed, which will break its tightness.

Before covering the roof with metal tiles, you should make sure that the sheathing is symmetrical and reliable.
Self-tapping screws screwed into the lower deflection of the tiles, they must enter strictly perpendicular to the plane of the sheathing boards.
When connecting two overlaps fastening is carried out in wave rises using shortened screws.
Installation of tiles begins from the lower left corner of the slope, subsequent sheets are laid on top previous ones.
Self-tapping screws screwed into each wave of tiles along the perimeter of the slope and in a checkerboard pattern in the interior areas. If a screwdriver is used for this, then its rotational effect on the material must be minimized.

Metal tiles - DIY installation + instructions

Now you know how to lay metal tiles correctly and we invite you to familiarize yourself with the most important thing - instructions for installation of metal tiles.

Installation of metal tiles - step-by-step instructions

How to properly cover a roof with metal tiles with your own hands? The first step is.

It is on it that all other roofing elements will be fixed. The system is constructed from wooden beams, while their size exceeds the dimensions of the sheathing bars.

The most important elements of the rafters are:

Mauerlat. This is the fulcrum of the structure.
Rafter legs. They hold on themselves and rely on the Mauerlat.
Racks. Strengthen the support of the rafter legs.

The rafters are fastened to the wall using so-called tavern. These are strips of metal that connect two structures with nails or screws.

Next are installed main insulating layers: insulation, vapor and waterproofing. Waterproofing film or the membrane is applied to the rafter system and fastened to it with a stapler. Thermal insulation is placed in cells, formed by the intersections of the rafter beams, and is fixed with the help of cords drawn crosswise in the lower plane of the rafters.

Installation of rafters

After completing the installation of protective structures, you can begin installing the sheathing, on which we will subsequently lay the roofing. She applied over rafters and waterproofing layer and is attached with self-tapping screws to these structures.

Installing metal tiles with your own hands:

Attached to the frontal board cornice strip, providing roof protection from exposure to wind.
When performing work, the need to ensure good natural ventilation space. To do this you need to leave gaps between all layers of the roofing cake. The basis of natural ventilation is the possibility of free air circulation under the roof ridge.
The last step is installation of metal tiles. It must be taken into account that the sheets must perform beyond the edges of the sheathing by 5 centimeters and aligned horizontally along the eaves line.
Ridge strip attached to additional two boards, which are installed at the joints of two slopes when installing the sheathing. Such measures are necessary to ensure additional sustainability of important structural element to negative impacts.

. They loosen the snow masses falling from the roof, making their fall relatively safe for building structures and for humans.
Junction strips. These products frame the joints of the tiles with all important structures, such as chimneys and ventilation pipes.
Corners and valleys. They protect all corner roof structures.
Low tides. Used to redirect flows of rain and melt water.

Additional elements

Beam spacing rafter frame should be no more 60-90 centimeters, otherwise the roof structure may sag.
When performing work, you must wear shoes soft sole and move along the tiles, stepping into its lower deflections. This will prevent the material from being pressed through.
Lack of contact between protective layers important not only to provide ventilation, but to prevent them mechanical damage during friction.
To provide additional ventilation, you can arrange dormer windows in the attic.
For level installation of all elongated additional elements need to pull the thread and secure it between two already installed structures.

This is what the technology for laying metal tiles on a roof looks like. This material has an approximate service life about 50 years, but without the need for repair work, operation will only take place when correct execution installation
