Installation of metal tiles: step-by-step instructions for self-finishing the roof. Covering the roof with metal tiles with your own hands Where to start laying metal tiles

Metal tile is a modern roofing material that successfully combines the attractive appearance of ceramic tiles with the light weight and inexpensive price of metal coatings. Its advantages are considered good performance, corrosion resistance and long service life. It is important that, knowing the features of this material and having basic building skills, you can easily cover the roof with metal tiles on your own. Do-it-yourself installation of a metal tile is reminiscent of the process of creating a multilayer cake, the components of which improve and complement each other. In this article, we will describe step by step a proven "recipe" for creating a reliable, high-quality roofing from a metal profile.

Laying metal tiles with your own hands is a proven way to quickly and inexpensively cover the roof of a garage, garden or small residential building. This roofing is a type of metal profile with a wavy relief that resembles the shape of a traditional tile. The metal tile is made of galvanized steel, which is coated with a polymer coating of pural, plastisol or polyester during the production process. Roofing from this material has the following advantages:

• A light weight. One square meter of metal roofing weighs 3.5-4.5 kg, which allows you to increase the step between the elements of the truss frame, reducing the cost of building a roof.
• Mechanical strength. The roof of this material has high strength and bearing capacity, so it can easily withstand snow and wind loads, even if the step between the rafters is large enough.
• Corrosion resistance. Roofing from a metal profile is not exposed to the destructive effects of corrosion, because it is reliably protected by a zinc layer and a polymer coating.
• Long service life. A do-it-yourself metal tile roof has been serving for more than 20 years, thanks to the high quality of the metal and the strength of the polymer protection.

Important! Knowing how to cover the roof with metal tiles yourself, you can save a lot, because installing a roofing costs as much as 50-70% of the cost of purchasing materials.

The composition of the roofing cake

Do-it-yourself installation of metal tiles consists in creating a multi-layer roofing pie, which consists of a vapor barrier, insulation, waterproofing and the coating itself. In order for a metal profile roof to last for a long time, it is worth choosing the right structural components that are suitable for each other and following the rules that the installation instructions prescribe. Roofing cake for metal tiles consists of the following parts:

1. Vapor barrier. This is the name of a film that allows steam to pass through, but blocks water and condensate, protecting the insulation from getting wet. The vapor barrier must be laid on the lower surface of the rafters and fixed with a construction stapler.
2. Rafter legs. To cover the roof with metal tiles with your own hands, you need to correctly calculate the step between the rafters and install them evenly on the ridge run and Mauerlat. The strength and load-bearing capacity of the roof depends on how many rafters the roofing material supports.
3. Thermal insulation. The installation of thermal insulation is carried out between the rafter legs of the frame, so the step between them must correspond to the width of the insulation.
4. Waterproofing. Waterproofing must be laid over the rafters so that it protects the wooden frame elements from condensation or atmospheric moisture.
5. Crate. This element of the truss frame is used to distribute the weight of the roofing material. Roofing material must be laid on the crate. The step between its slats is chosen in accordance with the weight of the coating and the angle of inclination of the slope.
6. Roofing material. Do-it-yourself metal tiles are laid on the crate. For fixing use special roofing screws.

Please note that there are 2 types of metal roofing - warm and cold. A cold roof differs from a warm one in the absence of a thermal insulation layer and vapor barrier in the composition of the roofing pie. This design is cheaper, but can only be used in cases where the attic or second floor is not heated.

Rafter frame and crate

Before covering the roof with metal tiles, it is necessary to assemble the truss frame. The frame is a kind of supporting skeleton of the structure, which supports its geometry, and also distributes and transfers the weight of the roof to the foundation of the structure. It is made from coniferous wood impregnated with an antiseptic and flame retardant, or metal. The metal truss system is more expensive, but can withstand heavy loads, so you can increase the step between the elements. The roof frame is assembled in the following sequence:

1. First of all, the Mauerlat is installed. The support beam is laid on the upper trim of the house, secured with metal studs embedded in concrete or anchor bolts. Mauerlat is made from a bar with a section of 150x150 mm and is mounted on the walls on which the roof slopes will rest. How many slopes are at the roof - so many support bars are needed.
2. Then puffs are installed that connect the Mauerlat in increments of 1-1.2 meters. Puffs are made from a bar 100x100 mm or 100x150 mm.
3. Vertical racks are installed in the middle of each puff in increments of 1-1.2 m. In order for them to stand vertically, they are supported with temporary slopes.
4. On top of the racks you need to lay the ridge run. This is the name of the timber that forms, the rafter legs will rest on it.
5. Next, it is necessary to mount the rafter legs of the frame in increments of 0.6-1.2 m. The step between the rafters depends on how much the roofing weighs, the section of the element and the width of the insulation.
6. The rafters must be covered with waterproofing to protect against condensation and atmospheric moisture. It is worth laying the film "in sag" so that it does not tear under the pressure of water.
7. Lastly, you need to mount a crate of slats with a section of 30x30 mm or sheets of moisture-resistant plywood. The step between the elements of the crate is chosen in accordance with the weight of the roofing material and how many degrees the angle between the surface of the slope and the base of the roof is. The flatter the roof, the denser the crate should be, and the smaller the step between the rivers.

Important! It is possible to cover the roof with a metal tile, regardless of its design. The minimum recommended slope for this type of roofing material is 12-15 degrees. If the roof is flatter, then the installation is carried out with the obligatory processing of the joints with a sealant to prevent leaks.

Insulation

Before laying a metal tile, you should take care of protecting the wooden frame elements from steam, condensation and moisture. Metal roofing has a high thermal conductivity, so it heats up quickly, but it also gives off heat easily, so it needs to be insulated. In the process of erecting a roof from a metal tile, 3 types of insulation are installed:

• Vapor barrier. The instructions for laying the metal profile prescribe the mandatory installation of a vapor barrier on the lower surface of the rafter legs. This role is played by special membranes that allow air to pass through, but block water, preventing the insulation from getting wet. After all, with an increase in the humidity of the thermal insulation material by only 5%, its effectiveness is halved and does not recover after drying.
• Thermal insulation. Insulation is laid between the rafters to keep the temperature in the house. It protects from cold air in winter and prevents heating of the under-roof space from the hot roof in summer. Mineral wool, ecowool, glass wool, polystyrene foam or polyurethane foam are used as insulation. How many layers of insulation are needed to protect the house from freezing is calculated in accordance with climatic conditions.
• Waterproofing. A waterproofing material that protects the rafter frame and insulation from moisture ingress is laid on top of the rafter legs. Strips of film or diffuse membrane are mounted in overlapping strips to prevent water from flowing between them.

Experienced craftsmen say that it is impossible to cover the roof with metal tiles without using all three types of insulation in a complex way. Only by working in a complex, insulation, vapor barrier, and waterproofing become effective.

Instructions on how to properly lay a metal tile are popular with inexperienced craftsmen. To work with this unpretentious roofing material, special skills or complex tools are not required. The laying of the coating is carried out using roofing screws, a screwdriver, a building level and sealant and a circular saw with a metal disc. The process of laying a metal profile is as follows:

1. Before laying the metal tile, the sheets are first cut. To simplify this task, you can purchase a metal tile, the length of the sheet of which corresponds to the size of the slope, then there will be no horizontal joints during laying, and you will not have to cut the material. In other cases, a circular saw or a jigsaw is used to cut the coating to size.
2. Then the metal tile is laid. The bottom row is laid out first, starting from the edge of the slope. An overlap of 10-23 cm or 1-2 waves is made between the sheets. The flatter the roof, the greater the overlap.
3. The joints between the sheets can be treated with a silicone-based sealant to prevent leaks.
4. Each sheet of metal tile is fixed with galvanized self-tapping screws, equipped with a wide press washer, which closes the mounting hole from water penetration.
5. After laying the coating, the ridge, ends, slope cornices are formed with the help of additional elements, and drainage elements are installed.

Important! Knowing how to properly lay metal tiles, without resorting to the services of a professional team of builders, you can significantly reduce construction costs. To cope with the roofing of this practical and lightweight material can be two in 3-5 days.

Metal roofing stands out from other roofing options. Still: roofing with a metal tile is easy, beautiful and inexpensive. Thanks to current technology, there are many varieties of this material, which are ranked by base material, coating, insole depth and geometry.

Making such a roof yourself is not the most difficult thing, especially if you arm yourself with knowledge and tools.

Types of metal tiles
To choose the right metal tile for a roof, you need to keep in mind the pros and cons of each of its varieties.

Based on:

• steel - the most popular type, extremely resistant to external influences;
• aluminum - the lightest tile, durable, does not suffer from corrosion. However, it is more expensive than steel, and the range of its colors is limited;
• copper - an excellent option for roofing, does not need a protective coating, looks noble.

In the photo - one of the varieties of metal tiles, aluminum cascade

By coverage:

• polyester is the cheapest option. Such a metal tile can be matte or glossy;
• plastisol is also not the most expensive type of coating. It is a plastic film;
• pural - metal tile-gloss. This coating is resistant to corrosion and is based on polyurethane;
• PVF2 is an elastic coating that is resistant to temperatures and has many shades.

Insole depth and geometry:

• andalusia - covering with a hidden mount. Minus - the need for accurate and frequent crates;
• bang - a tile with an impressive wave height, but a smaller installation width. Allows you to get the effect of "3D";
• country - this type is similar to natural tiles, has a sophisticated look (soft and even waves), easy to install and durable;
• cascade - the most economical option for metal tiles. The installation width is sufficient, the shapes are straight, which allows emphasizing the classic style of the building and its sophistication;
• Monterrey is the most common type. Very similar to a real tile, it can have symmetrical or asymmetrical steps, the profile is rounded.

Self-installation of a roof with a metal tile involves 3 stages: preparation of the structure, installation of a metal tile, installation of additional elements.

Installation instructions

For work you need:

• screwdriver or screwdriver;
• a hammer;
• cutting and metal scissors;
• hacksaw for metal;
• rail and markers for marking;
• jigsaw.

Preparing the truss system

1. We manage with the crate. The flatter the slope of the roof, the smaller the step of the crate. The correct distance is necessary for the precise installation of metal roofing sheets. Saturate the crate with fire and rotting agents.
2. If you intend to use the room under a roof, install thermal insulation.
3. Mount the vapor barrier from the special film, observing 3 rules:
   1. from 150 mm between sheets of vapor barrier;
   2. from 200 mm of material overlap on the walls;
   3. fastening with slight sag.

We lay metal tiles

Important! For cutting sheets of metal tiles, you can not use the "grinder". The area near the cut is very hot, the decorative, protective layers and zinc plating simply burn out. The sheets are corroded.

Installation of other elements

1. We mount the parts of the ridge with an overlap, the value of which is indicated in the passport. Through each wave of the lower sheets, the skates are fastened with self-tapping screws.
2. To equip the gutters, use the elements from the kit with metal tiles. Under them, special constructions of the crate are needed.
3. Eaves, gable boards and chimneys, ventilation ducts, dormer windows, cables, snow guards, fences, stairs and bridges are also installed using complete materials and the attached instructions.

Roofing mansard roof with metal tiles

Metal tile, gaining popularity, has not bypassed mansard roofs. The reasons are the same: simple installation, aesthetic appearance and durability.

In the photo - a country house with an attic floor, covered with a roof made of metal

Peculiarities

There are 5 features on which the installation of a mansard roof with a metal tile is based:

1. docking of sheets should take place along the wave;
2. sheets are also joined along the rows of the crate board, self-tapping screws at the joints are installed in each wave;
3. when mounted on a cornice, the roofing sheet protrudes 5 cm beyond the edge of the cornice, between the first board of the crate and the edge of the cornice - no more than 25 cm;
4. the ridge board of the crate is 1 cm thicker than the others for good ventilation, fastening takes place in increments of 0.8 m into the crest of the wave;
5. installation of the roof at the ends implies end strips on self-tapping screws with a step of 0.8 m. The same applies to gutters.

Installation instructions
The set of rules for installing a mansard roof with a metal tile will depend on its type. Consider a rectangular option:

• We mount the rafter system and the crate. The pitch for the rafters is 60-90 cm, the lathing board is 10 mm wide, 25 mm thick. We level the cornice board and hammer it.
• Then we install the hooks for the drain on the eaves bar. For better joining of all sheets, first they are fixed with screws through two rows, after that - completely.
• For normal fastening of 4 sheets in one row, 2 sheets are mounted, to them - a pair of another row. Seal at the joint is eliminated by leveling the capillary groove and cutting off part of the corner.
• In the presence of roof windows, it is better to use single-module sheets - 2 for each window.
• The metal tile is laid from the end - the ridge is mounted on the end strips with a ledge of 2-3 cm. We overlap the elements of the flat ridge, semicircular - along the profile line.

Important! Roof ventilation plays an important role. If the mansard roof made of metal is sloping, it is recommended to install an aero roller that blocks the snow from falling under the ridge. If the ridge is equipped with pinhole ventilation, sealing is required.

Do-it-yourself roofing with corrugated board

Decking has high quality indicators, including its versatility as a working material, ease of installation and reconstruction, minimal waste after work and the ability to install sheets without special training.

Types of corrugated board

When choosing a corrugated board, be guided by the marking letter:

• H ("bearing") - the most durable sheet, gives the structure amazing durability and durability;
• NS ("bearing-wall") - a universal view, has an average size of sheets and corrugations;
• C ("wall") - an elegant option used in the decoration of walls, roofs, the manufacture of fences and other things.

Installation instructions

Installation of the roof with corrugated board takes place in 3 stages.

metal roofing cost

The price of a metal roof varies depending on the cost of the material, roofing and additional work.

A good metal tile costs around 160-700 rubles. per square.

Work without materials will cost per square:

• 500-600 rub. - roof only
• 770-820 rub. - roofing and sheathing;
• 1000-1200 rubles - installation of the truss system, lathing, roofing;
• 1500-1650 rub. – a new mansard-type pitched roof with an attic, truss system, insulators, lathing, roofing.

Additional services can "fly a pretty penny":

• 250-280 rub. per m. – snow guards and drainage system;
• about 150 rubles. per m. - installation of cornice and end strips;
• about 450 rubles. per sq. m. – truss system from scratch;
• over 7500 rubles. – installation of a dormer-window in a ready roof.

Video

From the video you will learn how to professionally cover the roof with metal, avoiding common mistakes. Options for mounting additional accessories for this type of roof are also considered.

When purchasing one of the best roofing materials - metal tiles - do not save on components. It is better to purchase a complete set from one company: some companies do not provide a guarantee for their building materials if they are assembled by “foreign” components. If necessary, it is better to save on labor and install high-quality and beautiful metal tiles with your own hands.

In many respects, metal tiles are better than other roofing materials such as galvanized sheet, slate or bituminous tiles. The laying of this material is usually trusted to specialists, but if you have a desire, then you can do the installation work yourself.

Carrying out calculations

Before starting work, the master should understand a rather important point. Externally, a metal roof looks like many rows that run across the slope. The distance between rows is called a step. If a tile sheet has a pitch of 35 cm and 6 waves, then it is called a module. On the modern building materials market, canvases are offered that have a maximum of 10 modules. The minimum value is one.

If you wish, you can order tiles, guided by individual sizes. However, such material will cost much more. The length of the sheet should not be more than 7 m, and the minimum value is 45 cm. You can install the metal tile yourself (you must study the instructions) yourself. After reviewing it, you will be able to understand that in the calculations it is necessary to take into account that the waves and joints form an integral canvas along the length of the slope. If you determine the number of modules, you can calculate the amount of material that should be purchased.

The kit usually comes with steel two-meter strips, as well as steel sheets, the color of which is identical to the color of the metal tile. Planks are used for those roofs that have a slope of 30°. However, if desired, you can adjust the slope in the range from 11 to 70 °. When making calculations, it is important to take into account not the full, but the working, that is, the useful width of the material. In the first case, the value is 1180 mm, while in the second it is 1100 mm.

First you need to measure the length of the horizontal slope. The calculation must be carried out on the ridge or eaves. This value is divided by the working width of the sheet, which was mentioned above. The result obtained is rounded up, this will allow you to get the number of rows, taking into account the overlap. In general, it is possible to determine the area of ​​\u200b\u200bthe covered surface, and then the useful area of ​​​​one sheet. The first value is divided by the second, which allows you to get the number of sheets that you have to purchase.

Making a roofing cake

The system provides for the presence of a vapor barrier layer. It is laid inside the rafters from the side of the house. To do this, you can use the staples of a construction stapler. This will prevent steam from entering the heater. Otherwise, the process of decay may begin.

The technology of laying metal tiles provides for the location of the insulation on top of the truss system. Mineral wool is perfect for this. For waterproofing, you can use anti-condensation films or classic waterproofing. This is where the preparation ends.

Lathing installation

The roof lathing is necessary in order to provide a ventilation gap between the sheet of metal and the film. Otherwise, in the place where the metal will adjoin the film, the layer will quickly lose its properties.

For the roof sheathing, it is necessary to use a rail, the length and section of which are 135 cm and 30 mm, respectively. If you decide to use transmissive superdiffusion membranes, then the counter-lattice is not needed.

Preparation of tools and materials

Order means following the rules. At the first stage, it is necessary to prepare tools and materials, among them:

• metal scissors;
• electric drill driver;
• measuring device;
• marker;
• ladder;
• long rail;
• mounting tape;
• a hammer;
• individual protection means;
• waterproofing;
• roofing strips;
• slats for the ridge and ends;
• self-tapping screws;
• guide board;
• tiles;
• aero roller;
• decorative overlays;
• boards.

As for the latter, their size should be 2.5x10 cm.

Foundation preparation

Due to the fact that the metal tile has a small weight, it does not need a reinforced base, so you will need a regular wooden crate made of slats. The distance between them is determined by the size of the tiles, so as not to drive the screws into the void during installation. When determining the step, the location of the windows should also be taken into account, because there should not be rafters above them.

thermal insulation

The rules for the installation of metal tiles necessarily provide for the use of a heat-insulating layer. This stage is required not only to eliminate heat loss, but also to protect against noise during rain. The rafters are covered with vapor barrier material, it can be Izospan or Yutafol. The next step will be the laying of the insulation layer, then you should lay the antioxidant film and fix it to the rafters with wooden bars. The material between them should sag a little so that the condensate drains into the drain.

Installation of metal tiles

From metal tiles and the calculation of materials, you can do it yourself. All instructions for this are presented in the article. Installation of canvases can be done in one of two ways. If you work, starting on the right, then each new sheet will fit on the previous one. In order for the installation to be correct, four sheets are first tacked and aligned, and then the connection can be made with a self-tapping screw. This fastener must be of good quality, because the life of the coating depends on it.

The screws must be galvanized with propylene rubber sealing heads. This will close the holes when twisting. In the place where the four sheets are connected, a thickening will form. You need to get rid of it by cutting off part of the corner or straightening the capillary groove, which is located under the stamping line.

Installation of individual elements

Installation is carried out with an overlap of 2 cm. It is necessary to adjust the size of the wave to the width of the slope, otherwise the crest may end up on the pediment. The system should be supplemented with a roofing strip, and an additional sealing layer must be placed between it and the sheet material.

When windows or pipes located below the ridge are being equipped, it is necessary to take sheets with one module. For each structural element, you will need two such nodes. Step-by-step instructions for installing metal tiles for dummies involve installing an aero roller with sloping slopes. This element must be located between the ridge bar and the material. This will prevent the penetration of atmospheric precipitation under the ridge. The last node is installed on the slats, which are located at the ends of the structure. This is done so that the skate protrudes 3 cm.

Mounting a ridge on a metal tile will require some nuances to be observed if this part of the system is flat. In this case, all elements are fixed with an overlap. Whereas if the skate is semicircular, then it is necessary to follow the lines of the profile. When the roof slope exceeds 45°, the compatibility of a particular model of ridge batten must be checked in advance. It should be at an angle. If this is not done, then the consequences can be disastrous, sometimes you even have to replace the roofing. You can bend and unbend the ridge slats, if necessary, so that they follow the angle of the roof.

Arrangement of the valley

Each valley requires an additional board. Installation starts from the bottom and is carried out with an overlap of 30 cm. Under the ridge and flanging it is necessary to lay a sealant.

There will be a 10 cm gap between the sheets and the axle. Stepping back 1.5 cm from the stamping line, it is necessary to tighten the screws. If you did everything correctly, then after completing the work, you can make sure that at the place of fastening the sheet is in contact with the board where the valley is located. If you made mistakes, then the fasteners will be in other places, and the consequence will be that gaps form on the surface through which the roof will leak.

In order to cover the cut sheets during the installation of metal tiles, the step-by-step instructions of which are presented in the article, it is necessary to stock up on decorative overlays. There is no need to lay a sealant between them and the tiles. Products must be installed with a 10 cm overlap. It is important to exclude damage to the valley with self-tapping screws that are used to fix the overlays.

Quite often, the end and the beginning of the valley are located on the slope of the roof. If we take the installation of a dormer window as an example, then a separate board must be placed under the valley. For a window, a cutout should be made in the sheet, while a sealing material is located along the walls. At the same time, the plank will be able to cover the cornice overhang. Then the valley strips are installed, which are cut off at the edges. The protruding part will fit snugly against the tile sheet.

Installation of snow guards

Depending on what design features snow retainers have, today several technologies for their installation are known. At the same time, it is important to take into account the calculated power load, the type of roof and the location of structures on the surface.

On a metal tile, the instruction of which is presented in the article, provides for determining the number of profiles. In the future, they will be fixed on the brackets of the system. The number of profiles is determined taking into account the geometry of the roof. For those areas where snow accumulation is expected, glass holders should be installed in two levels. With an impressive roof area, the number of rows of the structure increases.

The placement of snow retainers is planned at the design stage of the coating; at the locations of these nodes, it is necessary to strengthen the crate with the help of additional support boards. The technology of laying metal tiles provides for the installation of snow retainers, which are fixed with long self-tapping screws fixed to the crate. Fasteners must go through the roofing.

When determining the number of fasteners, the angle of inclination of the roof, the design of the crate and the length of the slope should be taken into account. The sealing of the holes for the snow retainers must be carried out without fail; rubber gaskets must be used for this. Two seals are installed under the bottom mount. The distance between the fasteners must be equal to the limit from 0.5 to 1 m. The profile with an oval section or the pipe is inserted into the brackets. The elements are interconnected by through bolts.

On top of the waterproofing layer, another crate is made, then you can proceed to laying the sheets. After installing the first row, it must be aligned with the eaves. With the help of a roofing screw, the canvas is attached in the center. Laying the second sheet is carried out with an overlap on the first.

At the next stage of the installation of metal tiles (step-by-step instructions are presented in the article and should be studied by you), you can fasten the sheets with self-tapping screws already thoroughly. After that, the metal tile is attached to the crate, but the last sheet acts as an exception, which must be fixed only after the second row has been laid.

If you want to mount in several rows, then you need to work from right to left. The first three canvases are stacked according to the scheme that was described above. Self-tapping screws do not need to be screwed in completely so that you have the opportunity to align the sheets. The fourth canvas lies over the third, this will allow you to close the entire slope.

After you lay out all the sheets, you can screw in the screws until they stop. Installation of metal tiles, the step-by-step instructions of which will be of interest to you if you plan to carry out the work yourself, involves installing the ridge last, because the sheets are laid from top to bottom. All subsequent rows should be slipped under the previous ones. It is important to choose self-tapping screws, the color of which will match the color of the material. It must be remembered that the metal tile is strong, but light enough, so it can be blown away by a gust of wind. It does not matter where the material is located - on the roof or on the ground.

How to avoid mistakes

The step-by-step instructions for installing a metal tile must be followed by you. It provides for following some rules, among which should be highlighted the ban on working in shoes with hard soles, as well as on the impact on the crest of the wave. You can not step on the canvas with a full foot. Masters need to remember that you should not put your foot perpendicular to the slope. Material should not be handled with bare hands.

Conclusion

Quite often, the owners of suburban real estate and houses within the city entrust the installation of roofing material to specialists. If you also decide to follow their example, then you should be interested in the cost of the work. Installation of metal tiles costs 380 rubles. per square meter. However, to these works it is necessary to add the price of some other services, for example, the installation of component parts. They cost consumers 250 rubles. per running metre. performed at 450 rubles. per running metre.

However, this list cannot be called complete. It will also be necessary to install layers of heat and waterproofing, without which the roof will leak, and the materials at its base will be saturated with moisture.

A reliable roof, which has high-quality waterproofing and insulation along the slopes, is the dream of any owner of a summer house or a country house. Today, such a dream is easily achievable if it is fulfilled.

Before it will be made of metal tiles with your own hands, you will need to consider the issue of removing the old roof, which may lack waterproofing. In this case, everything will depend on the technology by which the roofing cake was made, and its condition.

List of items that will be needed in order to install a new roof to your house:

• hacksaw for metal;
• anti-condensation films;
• waterproofing;
• galvanized nails;
• self-tapping screws;
• sealing tape.

The process of performing control measurements with your own hands

After the installation of the rafters is completed, you will need to re-measure the dimensions of the roof slopes. This is due to the fact that during the construction there could well be any deviations. It is worth paying attention to the squareness of the roof, because due to the additional elements it will be possible to hide only small defects (no more than 10 mm).

It is worth knowing that during the roofing of the roof with metal tiles, the cutting of sheets must be carried out exclusively with the help of a hacksaw, a hand-held electric saw or special scissors.

It is worth noting that it is possible to use technology in which there is waterproofing only if the roof slope is at least 14 degrees.

The choice of the type of snow retainers for the roof will depend on what material the roof is made of and how much snow falls in a particular region. The main size that will determine the length of the sheets is the length of the slope. This is the distance from the roof ridge to the eaves, which must be set taking into account the overhang of the sheet from the eaves (up to 40 mm).

In the case where the slope is longer than 7 m, the sheets will need to be divided into two or more fragments that overlap (at least 150 mm). The disadvantage of long sheets, which have fewer joints, is that they are very inconvenient to work with.

It is worth knowing that during the cutting of sheets it is necessary to produce exclusively with the help of a hacksaw, a hand-held electric saw or special scissors. All places where bare metal remains must be treated with a special paint that protects the steel from corrosion. At the same time, it is not at all recommended to use a popular angle grinder with an abrasive wheel installed in order to cut sheets. Its use does not justify itself.

How to install the crate with your own hands

The space under the roof must necessarily have good ventilation, therefore, a crate and a counter-crate will be needed. Anti-condensate films will need to be placed between the rafters and sheets of metal. Waterproofing should be spread parallel to the eaves.

For a soft roof made of rolled materials, a continuous crate is required.

The material should sag a little between the rafters. A small slack in tension (1-2 cm) will be enough. Along the rafters on top of it, you will need to nail small bars with a section of 40x25 mm or more. This will be a counter-lattice, on top of which it will be necessary to fix the flat bars of the crate. The distance is equal to the step of the wave at the metal tile. The board that will go to the cornice will need to be chosen 10-15 cm thicker than the rest.

It is worth noting that the bars for the crate and all other wooden elements must be treated with an antiseptic without fail. He is able to protect them from insects and rot.

The arrangement of a metal roof must necessarily include the use of special materials for waterproofing. There are 2 types of waterproofing, therefore, it is important not to make a mistake here. The first is intended to protect the insulation and rafters from any penetration of moisture vapor from inside the room. The second waterproofing is waterproofing films that protect against wind, moisture and condensation. They must be installed exclusively on top of the insulation. They pass water vapor, and therefore it does not accumulate in the insulation. The slope of the slopes does not allow moisture that flows from the metal tile to linger on the film for a long time.

Do-it-yourself installation of a valley and a cornice strip

Installing the right roof made of metal tiles requires protection not only from the condensate that forms on the back of the metal sheets, but also from precipitation. They can pose a danger to the lower edge of the crate, therefore, a cornice strip may be needed here. It consists of a number of boards that are nailed to the crate overlapping each other. In order to do the installation yourself, you should install galvanized nails in increments of no more than 30 cm.

Scheme of the roof valley.

Valleys should be used when the slopes are adjacent to each other. The lower edge of the valley should be laid over the completed cornice strip. It is necessary to use a porous sealant to get rid of the gap between the roof covering and the bottom bar of the valley.

The overlay of the valley can give the roof structure a complete look, it must be installed after the installation of the sheets. Its fixation occurs in the upper part of the wave, while the step is 30-50 cm.

It is necessary to install the end plate using self-tapping screws. In this case, the step between them should be no more than 40 cm. The strips themselves must be mounted with an overlap (10 cm) in length.

How is the arrangement of the roof of metal tiles with their own hands

The installation of the coating should begin from the end of one of the slopes after the preparatory work is completed, which includes the laying of an anti-condensation film and the installation of the crate.

If the installation starts from the left end, the second sheet must be installed under the last wave of the first. When work begins from the right end of the roof, a new sheet must be laid on top of the last wave of the previous one. In the case when there is a hipped roof, installation will need to start from the middle of the slope, after which the laying is carried out evenly in both directions.

Each of the sheets has a capillary groove along its edge. Such a groove should be covered by the edge of the next sheet. It is necessary to align the sheets of the coating along the cornice strip.

Self-tapping screws, with which the sheets are fixed, must be in the deflection of the wave.

The obvious fact is that it is not difficult, but there are some nuances that you need to know about. For example, self-tapping screws, with the help of which the sheets are fixed, must be in the deflection of the wave. It is necessary to use only those screws that have a special sealing washer. At the same time, they will need to be screwed in strictly perpendicular to the material of the crate. The average consumption of self-tapping screws is not at all large. It is up to 8 pieces per 1 sq. m.

If you screw in the screws at an angle, they will not be able to tightly press the sealing washer, therefore, there will be a potential leak in the roof.

An important issue is the movement on the roof in the process of construction or repair work. It is worth noting that it is recommended to avoid movement on the finished roof altogether, however, if all existing rules are followed, it can cause only minimal problems.

It is recommended to use shoes that have soft soles. It is allowed to step only on the wave deflection and only in the place where the crate will be under the metal layer. In no case should you step on the crest of the wave.

Mounting the skate with your own hands to ensure good ventilation

A properly installed ridge is a guarantee of good, high-quality ventilation of the space that is under the roof.

This element must be given special attention at the time when a do-it-yourself metal roof is installed.

Cover sheets should not converge to each other, while there should be enough space between their edges under the ridge bar. Fixation of the skate should be done using self-tapping screws that are screwed into the top of every second wave. You will need to paste over the edges of the sheets themselves with sealing tape.

If you need to make a semicircular ridge on a hipped roof, it would be best to use special elements such as Y-shaped linings.

Even if the person who performs the repair work knows that he may make a mistake when making a joint with such a vertical surface as a pipe or wall. In such cases, the contact zone will be isolated with the help of an abutment strip and a self-adhesive seal. Additional sealing can be easily created with a sealant.

The lower junction bars must be installed in a groove prepared on the surface (pipe or wall). To do this, strobe should be performed, after which it will be necessary to remove dust and rinse the strobe. The junction bar is cut, installed and fixed with self-tapping screws.

After the work is completed, you will get an internal apron, but you will also need to organize water drainage. To do this, use a flat sheet of metal, the edges of which will form the sides.

In addition to the internal apron, you can also use an external one, which is created from the upper abutment strips. Install it in almost the same way as the internal one, with the exception of chasing. The edges of the planks are simply fixed to the wall.

Some difficulties may arise when working on roof breaks. Such elements can be internal and external. In the first case, an abutment bar is used, which is installed together with the seal. In the event that we are talking about an external fracture, you will need to use a cornice bar.

Do-it-yourself installation of a drainage system and snow retainers

Rectangular sections should be used. Their gutters need to be mounted below the edge of the roof by 2-3 cm.

Snow guards are installed on the mounting plate using self-tapping screws that reach the crate. They screw up every second wave.

Metal roofing has become one of the most used roofing materials in recent years. Such roofs can be seen not only on residential buildings, but also in large stores, warehouses, government agencies and commercial offices.

The material received well-deserved respect due to the optimal ratio of quality and cost. This refers not only to the price of metal tiles, but also the cost of roofing and periodic maintenance of the roof.

Metal tile - a material with a good combination of quality and price

Any type of truss systems can be covered with a metal tile, but simple gable systems are better. The simpler the rafter system, the less the amount of unproductive waste. If on a gable it does not exceed 2–3%, then on a four-slope it can increase up to 6–10%, and on a complex hip up to 15–18%. Complex roofs are recommended to be covered with piece or flexible materials.

All work on laying the roof is divided into several stages, the implementation of each of them guarantees the tightness, strength and reliability of the roof.

Regardless of the type of metal tile and the type of truss system, the main architectural elements of the roof are finished according to the same algorithm.

Consider mounting on some roof elements, technologies are universal.

eaves plank

It is used to perform two tasks:

• protection of the under-roof space from oblique rain. Protects the rafter system and crate from getting wet;
• improve the appearance of the roof, hides the wooden structural elements.

Important. The thickness of the first lath of the crate must exceed the thickness of the others, the difference corresponds to the height of the metal tile step. The fact is that it is in this place that the first row of screws will be twisted, and it is higher than the rest of the fixation points. The sheet must have an emphasis; for this, the height of the first rail increases.

Another nuance - the distance between the first and second lath of the crate should be 28 cm, between the rest 35 cm This is due to the features of the profiles and their linear dimensions. A strip for the eaves is attached to the first rail with self-tapping screws.

Lower (drainage) and upper valleys

Quite complex elements of the roof, it is here that leaks most often appear. What is the difference between lower and upper valleys? The first provides water drainage and guarantees the tightness of the roof. The second plays only a decorative role, closes uneven sections and additional fixation elements.

1. lower valley. The crate should be a continuous width of ≈ 20 cm on each side of the junction. To increase the tightness before installing the metal element of the valley, flexible bituminous materials can be used for additional waterproofing. Water is diverted to the cornice bar, from which it falls directly into the gutter. The valley is fixed with flat-head screws or special metal strips.
2. Upper valley. Decorative element covering uneven sections of tiles. It is screwed with self-tapping screws to the crests of the wave. The color of the metal element must exactly match the color of the roofing.

You need to work very carefully on the valleys, the appearance of leaks in these places has extremely negative consequences. They are difficult to notice - a knot of complex design, water can be invisible on the visible side of the roof for a long time, and at this time the wooden structures get wet and are affected by rot.

Chimney lines

In the classic version, they should have two hydraulic protections: the lower one is made of flexible materials that drain water to a long galvanized metal plate connected to the gutter, and the upper one. The second simultaneously with protection performs a decorative function. Metal strips are installed in chimneys in strobes, water from the strip falls on metal tiles.

Pass-through elements for pipes

Adjoining strips

They are installed at the joints of the roof with vertical brick structures and at the bends of the slopes. They look like metal strips bent at an obtuse or acute angle, the material of manufacture is the same as that of a metal tile. The slats are fixed to the ridges of the sheets; in some cases, a rubber or foam rubber seal can be used to seal large gaps between the slopes.

Skate

It has various geometric shapes, from a simple bent metal sheet to a convex round one. It is screwed with long self-tapping screws, the dimensions of the hardware should be 2–3 cm higher than the height of the coating wave. There are options for special universal fixing elements with a ridge bar for ventilation.

Prices for various types of roof ridges

Roofing ridge

They can be tubular, lattice and lamellar. They are used to prevent an avalanche of snow from the roof, during which there is a high probability of damage to the gutter or injury to people.

The most durable tubular and lattice, are fixed to the crate of the truss system.

The lamellar ones are screwed to the ridges of the metal tile and cannot withstand heavy loads.

The decision to install snow retainers is made taking into account the angle of inclination of the roof slopes and the climatic zone of the building.

1. Lifting sheets to the roof. The length of the sheets can exceed six meters, they should be lifted very carefully, not broken or dropped. To lift, you need to prepare a special structure and only feed it to the roof with ropes. It is not recommended to work in windy weather - large profiled sheets have a significant windage, it is very difficult to hold them in your hands. Especially when working at height and in an uncomfortable position.

   

2. Rooftop movement. It is necessary to work in shoes with soft soles and anti-slip coating. Step only into the deflection. If you need to reach out while tightening the screws, it is recommended to prepare a wooden ladder. It increases the area of ​​support and eliminates the possibility of deformation of the metal sheet. In addition, it can be securely fastened to the ladder, which increases work safety and meets safety requirements.

   

3. Installing sheets. Alignment should be done along the cornice line, overhang within five centimeters.

   

   Fixation is carried out only in the deflection to the crate. Only some additional elements are screwed to the waves. Fastening sheets through one longitudinal wave and into every second transverse wave. If the sheets are very thin, and the region is characterized by strong winds, then it is recommended to increase the number of fixation points. In the same way, you need to do at the junction or overhang. The general rule is that there should be about ten self-tapping screws per square meter.

   

4. There is sheet stacking patterns in one, two or more rows and on triangular slopes. A specific decision is made at the stage of ordering the roof and depends on the size and geometry of the slopes.

   

After an idea of ​​\u200b\u200bthe laying technology has appeared, tools and fixtures have been prepared, materials have been purchased, you can begin to cover the roof.

Step-by-step instructions for installing metal tiles

It is necessary to raise the tiles to the roof along inclined guides from wide boards. One person from below pushes, and two receive from above.

It is strictly forbidden to lift the sheets with a rope attached with a wire in the hole. Even light gusts of wind can shake it and injure workers. It is very difficult to stop a swinging sheet; in any case, it will have mechanical damage.

You can cut metal with elastic tools with carbide teeth (quickly and efficiently) or with hand shears for metal (slow, difficult and crooked).

It is forbidden to use a grinder with an abrasive disc for this purpose, as a result of friction, the metal is very hot, and all anti-corrosion coatings are destroyed.

Important. Metal chips should be immediately removed from the surface with a soft brush. If this is not done, then scratches will appear on the outer coating, they will have to be painted over. To touch up scratches, you need to use special paint.

Step 1. If you have a warm roof, then you should start by installing vapor barrier and windproof films. The first protects the insulation from the penetration of steam from the attic. The second does not prevent the removal of moisture from the mineral wool and does not allow condensate from the metal sheets to get back into the insulation. In addition, it prevents the blowing of warm air from the mineral wool, which improves the thermal protection parameters of the roof.

It is fixed with a stapler from the inside of the attic. Overlap at least 10 cm, be sure to use double-sided tape for gluing.

Especially carefully it is necessary to finish the places of exits of chimneys and other engineering communications. But no matter how carefully it is sealed, steam will still get into it a little. To remove moisture, a second film is used, which is fixed to the truss system from the outside after the installation of the insulation layer.
