In many ways superior to other types of roofing, such as slate, galvanized sheet, bitumen shingles and so on. Laying the material is usually trusted to specialists, but if you wish, you can install the metal tiles yourself.
Advantages of the material
TO strengths metal tiles include:
The only disadvantages include increased noise during precipitation, but this can be solved by installing a layer of glass wool.
Covering the roof with metal tiles begins with calculations.
Stage 1. Carrying out calculations
Let's make one thing clear first important point. Visually, a roof covered with this material consists of rows and waves (the first run across the slope). The distance between the rows is called the pitch. If a sheet of tile has a pitch of 35 cm and six waves, then it is called a module. Modern market building materials offers sheets for 1, 3, 6 and 10 modules.
Important! If desired, you can order tiles by custom sizes, but it will cost much more. It should be remembered that the length of the sheet should not exceed 7 m and be less than 45 cm.
When calculating and laying out, the fact that joints and waves should form a solid coating along the entire length of the slope is taken into account. Having decided on the number of modules, the amount of material is calculated based on the roof area.
In addition to the metal tiles themselves, the kit also includes:
- steel strips 2 m long;
- steel sheets 200x125 cm, having the same color as the tiles.
Typically, the strips are intended for roofs made with a slope of 30ᵒ, although if desired, you can adjust them to 11-70ᵒ.
Important! Minimum slope, at which installation of tiles is allowed, is 11ᵒ.
Stage 2. Preparing everything you need
To install tiles, you need the following equipment:
- metal scissors;
- ladder;
- electric drill;
- long rail;
- screwdriver;
- mounting tape;
- meter;
- hammer;
- marker;
- funds personal protection(mittens, plastic glasses).
You will also need the following consumables:
- waterproofing;
- tiles;
- roofing strips;
- aero roller;
- trims for ends and ridge;
- decorative overlays;
- self-tapping screws, sealing washers and for them;
- boards 2.5x10 cm;
- guide board.
Stage 3. Foundation
As noted earlier, metal tiles weigh little, so they do not need a reinforced base - you will need a regular lathing made of wooden slats. The pitch of the sheathing should be calculated according to the dimensions of the tiles, so as not to drive the screws into the void during installation.
Stage 4. Thermal insulation
Thermal insulation is necessary not only to prevent heat loss, but also to protect against the noise of rain. First, the rafters are covered vapor barrier material(for example, “Izospan” or “Yutafol”). Next, an insulating layer (no more than 25 cm thick) is laid, covered with an antioxidant film and attached to the rafters with wooden blocks.
Important! The material between the bars should sag slightly (about 2 cm) so that the condensate flows only into the drain.
Stage 5. Installation of tiles. Basic rules
- can be done in one of two ways. If the stacking of sheets begins on the right, then each new one is superimposed on the previous one. If it’s the other way around, then the previous sheets are superimposed.
- In order to ensure correct installation, four sheets of tiles, located overlapping relative to each other, are first grabbed, aligned, and only then finally connected with one self-tapping screw.
- Self-tapping screws must be of high quality, because the service life of the roofing largely depends on them. These must be galvanized screws with sealing heads made of propylene rubber, hermetically filling the hole when tightened.
- A thickening appears at the junction of the four sheets. It needs to be removed, for which part of the corner is cut off or the capillary ditch located under the stamping line is straightened.
Stage 6. Individual elements
Step 1. The end strips are fixed with an overlap (about 2 cm). The size of the wave is adjusted to the width of the slope, otherwise the crest may fit on the pediment.
Step 2. A roofing strip is added, then an additional seal is placed between it and the sheet of material.
Step 3. When arranging pipes or windows that are located below the ridge, sheets with one module are taken - two pieces for each structural element.
Step 4. For sloping slopes, an aerial roller is installed between the material and the ridge strip, which will prevent penetration atmospheric precipitation under the ridge
Step 5. The ridge is fixed on the strips located at the ends of the structure. This must be done in such a way that it protrudes by 2-3 cm. In the case of a flat ridge, all elements are attached with an overlap, and if it is semicircular, then only according to the profile lines.
It is also worth noting that, if necessary, the ridge strips can be bent and unbent so that they follow the angle of the roof.
Stage 7. Arrangement of the valley
An additional board is attached to each valley. Installation in in this case starts from the bottom and overlaps 25-30 cm. Below the level of the cornice, the bottom strip is cut, and flanging is made along it. A sealant is placed under each trim and ridge.
There is a gap between the axle and the sheets (at least 8-10 cm). Screws are screwed into the cut sheets one and a half centimeters from the stamping line. However, when fixing, the fasteners are made 25 cm from the axis of the valley. If everything was done correctly, then upon completion of the work the sheet at the fastening point will be in contact with the board where the valley is located.
Important! If mistakes were made, the fastening will be located in other places and, as a result, gaps will form on the surface through which the roof will leak.
To cover the cut sheets, decorative overlays are used, when installing which you need to remember some important points:
Often the beginning and end of the valleys are on the roof slope. Take, for example, installation dormer window. Here a separate board is placed under the valley. For the window itself, a cutout is made in the sheet, and sealing material is laid along the walls. In this case, the eaves overhang is covered with a plank.
Then the valley strips, previously cut at the edges, are fixed. The released part should adhere extremely tightly to the tile sheet.

Slopes in the form of a trapezoid or triangle
If the roof slopes have a trapezoidal or triangular shape, then it is necessary to install additional bars.
Step 1. The bars are attached on both sides of the “ridge” along the fold line of the roof.
Step 2. The cornice board is installed and assembled.
Step 3. The cornice system is being constructed.
Step 4. The tiles are laid. This is done along the line of one of the edges or the axis. The first sheet is aligned with the cornice strip.
Important! It is unacceptable that the distance between the cut corner sheets installed near the “ridge” be more than 10 cm.
Step 5. To install the ridge assemblies, perform the following steps. The ridge strips are aligned with the angle of the “ridge”. If a straight ridge is used, then it is cut according to the corners, and if it is semicircular in shape, then the installation of an additional plug (preferably plastic) will be required.
Step 6. Ridge strip lies strictly along the axis of the “ridge”. This is quite simple to do if the angles of the slopes are the same, but if they are different, then it is correspondingly difficult. To control the junction of the slopes, bright-colored mounting tape is used.
Features of material care
As already mentioned, metal tiles are covered with a polymer layer that protects against corrosion. But constant exposure to ultraviolet radiation, precipitation and dust sooner or later causes the destruction of the protective layer. That's why metal roofing should be cleaned regularly.
- Dirt and dry leaves are washed off with a damp fluffy brush.
- To remove more complex stains, you can use special cleaning products for polymer surfaces.
- Do not use aggressive chemicals– they can destroy the protective layer.
- Gutters are cleaned with a stream of water under pressure. The jet must be directed from the ridge to the eaves.
- To clear the roof of snow, you can use only those tools that, in principle, are unable to damage the coating.
If all these rules are followed, it will last about 50 years.

Metal tiles are one of the most popular roofing materials today. Relatively recently, modular metal tiles appeared on the market. Let's try to figure out what kind of material this is and what characteristics its manufacturers provide.
What is a modular metal tile with hidden fastening?
It is called modular because it has standard dimensions (modules) with one or two waves and fastening in the locking part (hidden fastening).
Like the more familiar sheet variety, modular metal tiles are made from galvanized roofing steel, 0.5-0.8 mm thick. From exposure to factors external environment the metal is protected by a multilayer polymer coating, which is also responsible for the attractiveness of the material. Due to high wave(60 mm) the characteristic profile imitating natural tiles. Modules, like sheets, are designed to pitched roofs buildings for any purpose with an inclination angle of 15⁰.
Key Features
The decorative effect and durability of modular tiles depend on the main characteristics of the metal and its coatings:
- Quality and thickness of steel.
- Zinc coating class.
- A type of polymer coating.
Modular metal tiles with hidden fastening are made from rolled thin-sheet galvanized steel with a protective and decorative paint coating of domestic or foreign production. The thickness of the roof metal must be at least 0.5 mm. If operation is expected under special conditions, this figure can be increased to 0.8 mm.
The corrosion resistance of the material depends on the class of the zinc layer; this parameter is regulated by GOST.
Rustam Nazmiev Specialist of the company "Kazan Steel Profiles"
U foreign manufacturers rolled metal, for example, from the Swedish metallurgical company SSAB, roofing steel coated with pural has a layer of zinc - 18-20 microns on each side (275 g/m²). Metal Russian manufacturers, such as PJSC Severstal, OJSC NLMK, OJSC MMK - this is class 2 zinc coating, according to GOST 140 - 220 g/m². Galvanized metal with a smaller layer of zinc is not recommended for use as a roofing material.
Resistance of metal tiles to mechanical damage, temperature influences and aggressive environment determined by the type of polymer coating and its thickness. Modular metal tiles with hidden fastening are made of galvanized steel with various polymer coatings.
- Polyester (PE) - the pioneer of the polyester-based industry, matte or glossy finish is resistant to high temperatures and deformations, average mechanical resistance and decorative properties, thickness – 25 microns.
- "Steel velvet" - has improved performance characteristics. Coverage more high quality, textured, matte, combining durability and attractive appearance. Metal thickness 0.5 mm, coating thickness 25-30 microns.
- “Steel cashmere”, metal thickness from 0.5 mm. New polyurethane coating from PJSC Severstal, thickness - 50 microns.
- Pural is a modified polyurethane with polyamide additives, especially resistant to any atmospheric and mechanical stress, thickness – 50 microns. Considered one of the the best coatings among polyurethane.
Other options are also possible - adding ceramic granules to polyester, offset printing, imitation of the texture of various materials.
The main advantage of modular metal tiles with hidden fastening
Conventional metal tiles are installed in a standard way– with self-tapping screws to the sheathing. In this option, the fastener remains on the surface of the sheet. Under the influence environment Over the years, the rubber washer hardens, cracks, ceases to function as a sealed fastener, and requires tightening. Therefore, through-mounting points for conventional metal tiles are potential places for roof leakage and corrosion.
For metal tiles with hidden fastening, installation to the sheathing is carried out in a special locking zone, which is covered with the next sheet. In this case, you can use galvanized unpainted screws, which reduces the cost of fasteners. Hidden fastening protects fasteners from external influences. The modules are fixed to each other using a protrusion Z-shape, the bottom edge of the next row fits into the groove of the previous one, both in a horizontal connection and in a vertical one. This combined fastener significantly increases the stability and rigidity of the roof and makes horizontal and vertical joints of sheets invisible.
Modular tiles are convenient to store and deliver in sight small size leaf.
Rustam Nazmiev
Modular metal tiles with hidden fastenings form a tight, strong adhesion of sheets due to the fact that each sheet is fixed inZ lock. The step height (26 mm) also adds rigidity, significantly affecting the structural properties of the tiles. She is not afraid of strong wind and snow loads.
As for the installation process, it is possible to install compact and lightweight modules yourself. Indeed, lifting a small module measuring 1.17x0.85 m and weighing about 5 kg onto the roof is much easier than a long sheet along the length of the slope. No more than two installers are required for installation. The craftsmen of our portal recommend strengthening the first row.
Nikolay11111 User FORUMHOUSE
Modular metal tiles with hidden fastening - the material is quite interesting, effective, and due to the height of the wave and the Z lock, it looks chic. We always fasten the first row at the edge of the cornice not with the original hooks, but with self-tapping screws, this is more reliable. With ordinary metal tiles, the joint is always visible when looking at the roof from a certain angle. Modular metal tiles do not have this drawback, provided that they are no more than 2-row (2 waves of 350 = 700 mm or another standard size, the essence does not change). The roof covering looks like a continuous, monolithic, metal carpet; no joints are visible from the ground.
It is also advised to pay more attention to the quality of the sheathing and the installation method.
Nikolay11111
Also, modular tiles are very demanding on the quality of the sheathing; it must be perfectly flat, with strict adherence to the pitch of the steps. For beginners the most easy option styling - ordering, it will take longer, but better. Yes, indeed, the modules are lightweight, and one person can do the installation, the main thing is knowledge. I see the advantages in comparison with sheet metal in a much more impressive form, hidden fastening and durability.
Rumors about a large overuse of modules are exaggerated, and on the roofs complex configuration the percentage of waste is generally insignificant.
Rustam Nazmiev
On complex multi-slope roofs modular option In terms of material consumption, it turns out to be much more economical than a traditional metal tile (along the length of the slope) - since the cut pieces can be reused for small parts of the roof instead of using a whole sheet.
What to look for when choosing
Modular metal tiles, like sheet metal tiles, are universal and can be used both on a small private house and on a large building, if they allow an angle of inclination. Large selection color range, texture and profiles makes it possible to select the appropriate material for any style and status. It should be taken into account that the more aggressive the operating conditions, the stronger the protection should be. Polyester derivatives are now almost as good as more expensive polymers in terms of decorative properties, but they fade faster and are less durable. The warranty period issued by manufacturers also depends on the polymer layer. The best option Based on the combination of decorativeness, durability and wear resistance, pural and its variations are considered.

Description
A module is a separate, completely finished part that can be easily installed on any type of roof slope. Small in area and light, only one person can install it, which is why builders of private houses love it so much.
The tile modules are made in one piece from sheet steel according to Swedish technology, with matte or glossy finish.
The product has a unique shape - five lower and six upper waves, and the unusual angle of the tiles helps during installation - the sheets lie perfectly flat with an excellent fit to each other over the entire roof area. The lower relief part of the wave only once again emphasizes the exclusivity of the form metal tiles Venice, it can be put on a par with the most exclusive views ceramic products for roofs.
The tile consists of:
- High-strength polymer layer;
- Primers on the bottom of the zinc base
- The product is coated with an anti-corrosion layer of high-quality protective varnish.

Among other things, it is very economical and leaves less waste during installation.
Particularly relevant are modular tiles for roofs with complex slopes, attics, or several at once. In such a house there are always several chimney pipes, which, with another type of roofing material, are quite difficult to equip and waterproof. And small-sized modules can be stacked as required by the design itself. complex roof, and it is easy to cut and adjust to the desired size.
Each sheet has special holes, with the help of which it is successfully attached and connected to other elements of the roofing material; the seam is practically invisible, which will undoubtedly affect the impermeability of moisture and raindrops. But for all these conveniences, of course, you will have to pay much more than for simple sheets metal ceramics.
Take a closer look at the Venice ceramic sheet - you will see a characteristic bend on it, this was not done by chance, this detail is intended to give the sheet special resistance from the onslaught of bad weather and all kinds of winds.
In addition, during roofing work and fitting parts, very little waste remains; they are cut without crumbs, leaving solid parts that can then be used to cover chimney pipes or other inaccessible places; there are many options for their use, and waste-free production of course can only be attributed to positive qualities metal ceramics.

Installation instructions
Pay attention! When flying with metal tiles, there should be instructions on basic work, but if there is none, then you need to know:
- The finished parts already have all the necessary holes for fastening; you don’t need to do anything yourself;
- Small recesses ensure that joint seams are invisible;
- All recesses have a cup-shaped appearance, which acts as a waterproofing agent, they prevent moisture from entering;
- The unique front part creates conditions for ventilation, which will affect the life of the rafter system.

For high-quality installation Prepare special tools:
- Electric scissors for cutting purposes;
- Battery-powered screwdriver - if you don’t have one, working with a long wire can complicate the work;
- Ordinary construction scissors for cutting metal;
- Special powerful stapler and hammer;
- Level, marker and folding measures.
Step by step:
- First you need to assemble the rafters and lay the sheathing on them;
- Cover the legs of the rafters with a septic tank and you can use construction foil:
- The distance between the slats along the rows is 290 mm, along the axis - 350;
- Then auxiliary strips are attached in the places of chimneys and drainage systems;
- After preparatory work finished, you can begin laying metal tiles;
- Place the first part in the lower right corner, secure it thoroughly with fasteners;
- The next product is placed along the end part of the previous sheet, self-tapping screws are placed in the finished holes and fastened;
- Lay all the material using this technique, do not forget about the ridge and drainage system.
You will also need to select parts for finishing the chimney; you can do this from the waste that remained from cutting the tiles.

What are the advantages soft roof before metal tiles exist and which of them are the most important is described in detail here
This article describes what they are and how to choose the right building material for yourself.
Metal tiles are considered one of the most popular roofing materials. It can be seen on construction sites of large public buildings and during the construction of small private houses. Everywhere they appreciated the durability, reliability and attractive design this material. So that the roof, after all the work, fully complies with the best technical specifications, it is necessary to install a metal tile roof on professional level. To do this, you will have to thoroughly study all stages of the work.
The first step to installation work– this is an acquisition required quantity roofing material. If we are talking about metal tiles, then you should first do everything necessary calculations so as not to make a mistake when purchasing.
Metal tiles differ from many roofing materials in that they have a clearly defined direction, that is, the sheet can only be used in one direction and swapping “top” and “bottom” is unacceptable. This fact leads to slight difficulties in calculations, since there are fewer possibilities when cutting.
Metal tiles are measured in modules, that is, in sheets with certain dimensions. The module consists of six horizontal waves with a step between vertical rows of 350 mm. On the construction market you can find sheets with parameters of one, three, six or ten modules.
Important ! Unlike other types of roofing, which have standard sizes, metal tiles can always be made “to order”, taking into account the specific dimensions of the roof of the house under construction.
When calculating the number of sheets, you can use a special calculator, but it is better to work with ready-made drawings of the roof of the house. On them, to scale, it is worth placing the sheets so that cutting waste is minimal. For better design It is worth taking into account all the requirements contained in the installation instructions for metal tiles.
The work is carried out in strict sequence and is divided into six stages:
- Assessment of the geometric clarity of the roof and preparation of metal tile sheets for installation.
- Installation of waterproofing.
- Manufacturing and installation of sheathing.
- Arrangement of layers " roofing pie».
- Taking measurements and cutting sheets.
- Installation of sheets of roofing material.
- Installation work additional elements roofs.
Laying metal tiles involves the sequential formation of all roofing layers
In addition, working with metal tiles requires precise knowledge of which tools are acceptable to use and which are best avoided.
Rules for cutting sheets
Metal tiles have a protective polymer layer over the entire surface. Any damage to it inevitably leads to the development of corrosion and a reduction in the service life of the roofing material. This can only be avoided by following a number of rules:
Having planned the location of the metal tiles on the roof of the house and making sure the availability necessary tools, you can proceed to the installation procedure itself.
Preparatory stage
Before covering the roof with metal tiles, it is necessary to critically assess the condition of the roof itself and prepare it for the start of work. Conventionally, preliminary measures can be divided into the following actions:
- Removal of old hard roofing, if any;
- Exiting all smoke, ventilation and other penetrations through the roof;
- Completion or stop of façade finishing work.
Important ! Removing splashes of paint and other solutions from a layer of metal tiles can damage the protective layer of the sheets, as well as deform the roof surface.
- Check the geometry and dimensions of the roof: measure the diagonals of the slope and make sure there are no irregularities on the surface.
- Check the angle of the roof. The standard tilt must be at least 14 degrees, in rare cases it is allowed to carry out work at 11 degrees.
Important ! If minor distortions in the roof are detected, they can be corrected when installing the sheathing or using additional elements if the unevenness is located at the ends.
Installation of sheathing
For lathing, edged boards pre-treated with an antiseptic are used. Recommended dimensions – 100x25 mm. Installation is carried out from eaves overhang in compliance with the mandatory rules:
- The first board is placed immediately along the eaves overhang, strictly horizontally. Its thickness should be 10-15 mm greater than that of other boards. This difference will allow you to compensate for the height of the support points of the first and then subsequent modules.
- The second beam is attached at a distance of 250-300 mm.
- Subsequent boards are arranged in larger increments - 350-400 mm.
- Every five rows, control measurements are taken of the distance between the sheathing beams.
Important ! Control measurements should be carried out starting from the very first board, since any mistake with the horizontal components of the battens will lead to the fact that the entire work will have to be redone.
Correct installation Lathing is the key to successful roof covering with metal tiles
The installation of the sheathing ends with strengthening the ridge and end strips. At the same time, to attach the ridge, you should take care of additional boards measuring 100x25 mm. For the ridge board, take more thick timber– by 10-15 mm. This will help create the necessary ventilation gap when installing roofing material.
And the wind strip is attached in such a way that it is located above the sheathing to the height of the metal tile sheet.
Important ! If the design takes into account drainage from the roof, then the installation of brackets must be carried out when installing the sheathing.
Roof waterproofing
Laying the waterproofing layer must be carried out before installing the sheathing. The task of waterproofing is to allow condensation from the insulation layer to evaporate, but at the same time prevent the penetration of moisture from the outside.
When figuring out how to cover a roof with metal tiles, you should pay a lot of attention to the compatibility of materials. For example, it is recommended to use a membrane as waterproofing. Its installation must be carried out across the slope, and the joint of the film must be overlapped, with an overlap of 100 mm.
The film is fastened along the counter-lattice for better ventilation between the film itself and the metal tile.
Waterproofing is carried out before installation of the sheathing.
Steam and heat insulation
To insulate the under-roof space, it is mandatory to use vapor barrier films and insulation, providing a comfortable microclimate in the house.
Vapor barrier is necessary so that the insulation is not exposed to water vapor from the premises. Providing protection thermal insulation characteristics, film becomes a mandatory attribute warm roof.
Installation of roofing layers is carried out in accordance with the requirements for the materials used. Required condition There is a tight joining of films with the creation of additional insulating layers.
Important ! When laying metal tiles on cold roof There is no need to install heat and vapor barriers.
Cutting and installation of sheets
Sheets of metal tiles can be cut both on the ground and on the roof itself. Installation can be carried out in any direction, the main thing is to follow the technique, rules for laying and fastening roofing material.
The installation technology requires you to adhere to a number of simple instructions:
To fasten sheets of metal tiles, self-tapping screws are used that match the color of the roofing material. Each element is installed together with a gasket, the purpose of which is to minimize corrosion damage. The size of the screws is 4.8x28 mm. They are screwed into the sheets strictly perpendicularly so that the gasket underneath them is slightly compressed.
Important ! The chips formed when installing self-tapping screws should be removed with a soft brush.
After tightening the screw, the strip underneath should be slightly compressed
Each house has unique architectural features. To take into account all the nuances during installation, it is recommended to use not only textual information. The most useful, necessary and visual aid on how to cover a roof with metal tiles is a video. Its viewing is required for everyone who does not study roofing work professionally.
Conclusion
Metal tiles are beautiful and durable material, great for almost any home. The apparent ease of installation simply beckons you to do the work yourself. But, as when working with everyone building materials, here it is worth considering a lot of significant and not so significant points.
Only those craftsmen who constantly work in the field of roofing installation can know all the features. By entrusting the work to professionals, you can relax knowing that everything will be done correctly. the highest level, which means the house will be cozy and comfortable.
For arranging the roofing part in lately Metal tiles are increasingly being used. The material is supplied in the form of profiled sheets with a polymer coating. If you wish, you can install the metal tiles yourself. Step-by-step instructions will help you do this without serious mistakes.
Work on laying roofing fragments
The products are based on steel sheet thickness 0.45-0.55 mm. It is galvanized and has a special polymer-based coating. The cost of production may vary depending on the thickness of the metal and the type of protective layer.
List of advantages
First of all, it is necessary to highlight the following advantages:
- aesthetic appeal;
- weather resistance;
- affordable price;
- lightness of the main elements.
Pay attention! Polymer coatings perform not only a protective, but also a decorative function, since their colors can vary over a fairly wide range.
Few disadvantages
Since the sheets have a small thickness with sufficient large sizes, the risk of damaging them during careless installation still exists. If all the rules are followed, the integrity of the elements is difficult to violate.
Another disadvantage is the appearance of a noise effect when heavy rain during operation. However, with proper soundproofing of the living space, this disadvantage is completely eliminated.

Tools for installation work
It is necessary to prepare in advance a set of tools and additional devices for the work:
Pay attention! It is forbidden to cut sheets using abrasive wheels, since high temperature exposure leads to the destruction of not only the polymer, but also the zinc layer.
Basic set of additional parts
The step-by-step instructions for installing metal tiles should mention the main elements used in conjunction with the sheets. They are used depending on the roof configuration and operational features.
We suggest taking a look at the list of basic parts:
- a ridge is required to close the upper joint between two slopes;
- the end strip is necessary to decorate the edges on the side of the gable overhangs;
- the valley is installed in the places where the slopes combine;
- the cornice strip is attached to the side of the gutters;
- the junction strip is mounted in the presence of a pipe and other protruding structures;
- A snow retention element is needed to prevent snow from sliding off the roof.
Instructions for installing metal tiles: step-by-step execution of work
Loading and unloading of products can be done manually, but during the work a certain number of people must be involved. Usually 1 person is required for 1.5-2 linear meters sheet length. That is, when unloading metal fragments with a length of 6 m, 3-4 people should be present.
Waterproofing device and fixation of control bars
If thermal insulation is installed between the rafters, then waterproofing material must be present in any case. It is attached with brackets to the load-bearing part of the roof. The canvases are spread across rafter legs with an overlap of at least 15 cm on all slopes.
50x50 mm bars are nailed directly onto the rafters, providing a ventilation gap between the waterproofing and roofing material. For fixation, nails of at least 90 mm are used.
Correct installation of sheathing under metal tiles
Typically used as sheathing edged board 25 mm thick and 100 mm wide, but the final choice will depend on the pitch of the rafters. The elements are attached to 50x50 mm bars using nails no less than 70 mm long. The distance between the boards depends on the wavelength of the metal tile used.
In the place where the ridge element is installed, it is recommended to install two planks close to each other. This will simplify the installation of the ridge on the metal tiles. The same should be done at the places where the valleys are attached. The bottom board of the sheathing should be higher than the others by the height of the wave. Usually the thickness of the lining is enough to compensate for the difference.
Installation of parts mounted to sheets
To protect the ventilated space under the roof from the penetration of moisture and street debris, installation is carried out cornice strips metal tiles. A ventilation tape must additionally be attached to the ends of the 50x50 mm bars.
When installing the valley, a universal seal is laid. The bottom edge of the element should be on the surface of the cornice board. When joining horizontally, an overlap of at least 30 cm is made.
Lining a brick chimney involves extending the waterproofing membrane by at least 50 mm. A groove is made in the pipe itself, the depth of which should be at least 15 mm. Water is discharged into the valley located in the immediate vicinity.
The process of laying and fastening sheets
All sheets must be aligned horizontally with an extension of 50 mm beyond the sheathing. When fixing metal elements, the following points should be adhered to:
- the self-tapping screw must be installed in the deflection of the wave, where the sheet is adjacent to the sheathing;
- fastening to the bottom board is carried out above the step directly through the wave;
- Along the edge of the slope, fasteners are screwed into each wave.
Installation of end strips and ridge
Elements for closing the end joints are mounted in the direction from the eaves overhang to the ridge. The overlap on adjacent planks should be 10 cm. The recommended spacing between fasteners is 35 cm.
As for the skate, it is fixed to the upper crest of every second wave. When building up elements, an overlap of at least 15 cm is left. Self-adhesive sealing tape is attached along the entire length.
Additional instructions for installing snow guards on metal tiles
The number of elements to hold snowdrifts on the roof is selected taking into account the geometry of the roof. In areas of heavy snow scraping, two rows can be installed metal profiles. Pass-through type snow guards are optimal solution for individual buildings. They are attached using long screws to the sheathing itself through . The distance between fixation points usually ranges from 50-100 cm.
