Roof covering with corrugated board. How to properly cover the roof with corrugated board with your own hands: the order of work from the crate to the last self-tapping screw How to cover the roof with a professional sheet

For a comfortable stay in the house, it is important to make a high-quality and reliable roof with a good coating. To date, one of the best roofing is corrugated board. It reliably protects the roof from leaks, collapses, provides tightness in the under-roof space. And the most important thing is that it is environmentally friendly. However, the correct installation work plays an important role. Only in this case, the corrugated roofing will serve you for many years. This article will provide detailed instructions on how to cover the roof with corrugated board with your own hands, as well as video and photo materials.

As mentioned at the beginning of this article, corrugated board has a lot of advantages, which makes it an indispensable roofing material. You can also note other positive aspects of this material:

The profiled structure of the sheet has a high bearing capacity.
The lightness of the material greatly simplifies the work with it.
After laying the sheets on the roof, no joints are formed. This ensures the tightness of the coating.
Due to the special polymer coating, the material does not corrode, and as a result, its service life increases.

Note! Laying corrugated board on the roof should not cause any special problems, and at first glance, everything may seem extremely simple. However, during installation work, no flaws and inaccuracies should be allowed.

For the transportation of corrugated board, specialized transport is required. Sheets must only be laid horizontally. It is also recommended to pull them together with slings, after laying them on a hard and even surface. There are also special requirements for the driver. It is necessary to drive the car without sudden braking and turns. Failure to do so may result in damage to the material on the way to its destination.

In addition, it is important to ensure high-quality storage of corrugated board. The base must also be level and firm. If it's time to lift the sheets to the roof, then you need to do this with the help of a log. Their length should correspond to the height of the roof from the ground. You can lift several sheets at once.

Note! If the weather is windy, then it is impossible to lift the sheets onto the roof.

Today, such types of corrugated boards are known:

Mark C. The canvas has a sinusoidal or trapezoidal shape. If you decide to perform a decorative roof finish, then this option is just the way.
RS brand. It is used both for laying on a roof, and on walls.
Mark N. This model is equipped with additional stiffening ribs.

It is very important to know what slope angle is allowed for a particular product. Each manufacturer develops individual instructions. Therefore, when buying, you should ask for instructions, which is called the so-called "Installation of the roof from corrugated board instructions." Based on this, it is important to consider the future slope of the roof. Knowing the slope will help you calculate how much overlap each sheet should have. Below are some calculation options:

A slope of less than 15° will provide an overlap of 200 mm or more.
A slope of 15 to 30 ° will provide 150–200 mm and no more.
If the slope is less than 12 ° or the roof is flat, then each seam and joint should be carefully sealed. Otherwise, the roof will not cope with its functional responsibilities.

Calculation

Before buying material, it is important to calculate the number of sheets. This requires information regarding the width and length of the slope, as well as what brand of corrugated board will be used. To calculate, you can use a special program or draw a roof on a reduced scale. This will help to perform almost accurate calculations. It should not be forgotten that the sheets are overlapped. Depending on the angle of the slope and the grade of the profiled sheet, the overlap will differ. So you will find out how much the length and width of the sheet will be “eaten up”. Moreover, do not forget to add an overhang to the cornice, which can be up to 30 cm.

Note! It is necessary to purchase all additional elements in advance, for example, valleys and slats. They will be fixed in places where the slope has a certain kink, from the end, on the ridge and in other similar places.

Each sheet is attached to the crate with self-tapping screws. This is the only way to ensure reliable coverage. Fasteners are subject to special requirements. So, they must be made of galvanized steel. In this case, each self-tapping screw must have a special gasket made of elastomer or neopreon rubber. This rubber will provide a hermetic docking of the self-tapping screw with the profiled sheet. Due to this, moisture will not penetrate the wooden elements of the roof, which means that rotting of the supporting structure will be prevented.

The following technical parameters are presented for self-tapping screws:

Size 4.8x32mm, 4.8x60mm and 4.8x80mm.
The presence on the cap of a protective and decorative coating in the form of powder paint and a layer thickness of 50 microns.
The surface is treated with electrolytic galvanization with a thickness of 12 microns.
The presence of a protective gasket made of elastomer for profiled sheets and for valleys made of aluminum sheet.
Self-tapping screws should contain stabilizers that do not allow the negative effects of ultraviolet rays.

Note! When buying coating sheets, purchase one color and self-tapping screws. This will give the aesthetics of the entire roof.

It should also be mentioned about special seals, which are made of foamed polyethylene and polyurethane foam. The sealant is placed between the sheet and the crate. It is believed that a strip seal with a rectangular cross section is universal. But it will be much more effective to use those seals that repeat the shape of the profiled sheet.

The presence of a seal reduces the noise of a metal roof, increases the quality of the thermal insulation of the cake and increases the service life. A special adhesive is applied to the strips of the seal on both sides, so its installation is greatly simplified. It is very important that the sealant be perforated for ventilation in the under-roof space.

Note! The presence of a seal eliminates the large gaps resulting from the fit to the roof structure of the sheet. Birds, insects and cold air often get into these gaps. The special properties of the sealant material make it bioresistant and moisture resistant.

Immediately before the installation of profiled sheets, hydro and vapor barrier is laid. To make a vapor barrier, you can purchase a special film or roofing material, in extreme cases. The vapor barrier is attached to the crate. It is recommended to lay it from the lower edge of the roof. Due to this, each subsequent layer will be lower and moisture will not penetrate to the wood.

Note! If the brand of corrugated board S-8, S-10 or S-20 with a thickness of up to 0.5 mm is used, then the crate must be continuous. In all other cases, the step of the crate is selected individually from the characteristics of the roof.

Separately, it is worth mentioning about the layer of insulation, which will save 25% of heat. Those roofs on which corrugated board is mounted are advised to use matte insulation. The result is a roofing cake:

A layer of vapor barrier film.
Insulation.
The final waterproofing layer.

When making this “pie”, a “cold triangle” should be organized. Its presence will ensure a good passage of warm and cold air through the cracks in the cornice and ridge. So, natural ventilation will be created, which will prevent the formation of condensate.

The laid waterproofing layer will retain all the properties of the insulation. Otherwise, with strong moisture on the roof, an ice crust, dampness will form and, as a result, the process of wood decay is inevitable. For this reason, the material for each layer of the cake must be chosen carefully. It must be of high quality.

In order for all the work to go smoothly and without failures, take care of the availability of the necessary tools in advance:

rope;
roulette;
screwdriver;
a hammer;
metal scissors;
construction gun with sealant;
marker or pencils;
construction stapler;
drill.

Note! Profiled sheets are cut cold, as the polymer coating is not resistant to high temperatures. It is better to use scissors for metal or a jigsaw. At the same time, treat each cut with an anti-corrosion primer. This will increase the life of the coating.

Laying scheme

The sheets are overlapped on the lower edge of the roof, and the screws are twisted into the bend of the wave. Compliance with a specific installation scheme will create a reliable roof. First of all, under the valley plank at the level of the crate, a dense flooring is made from the groove at a distance of 60 cm from both sides. The lower boards of the valley are mounted with an overlap of 20 cm. The bottom plank is fixed from the edges with nails, and the final fastening is carried out together with the roof. If the slope is gentle, then sealing mastics should be used here.

Under the ridge, the bottom bar is wound up by 25 cm. A profiled or universal seal should be laid between the profiled sheet and it. As for the installation of end boards, it is better to fix them above the crate, then it will be possible to fix the end plate. This structure will be called the wind corner. After that, a cornice strip and filing with corrugated board are installed. It is mounted below the profiled sheet.

Installation of sheets will depend entirely on the type of roof. For example, if the slope is gentle, then a longitudinal sealing gasket is used and overlapped by one wave. If the slope is a steep compactor, it is not necessary to use.

Note! If you have a hip roof, then the installation begins with the hip itself. A cord is stretched along the cornice and each subsequent sheet is aligned along it. It is unacceptable to do this at the end of the ramp.

There are two methods for laying sheets of corrugated board on the roof:

Vertical direction. In this case, the first sheet with temporary fastening is laid below. Similarly, the sheet is mounted on the second row. Next, two sheets are stacked side by side, a square of 4 sheets is obtained. More sheets are stacked to it and so on. This method is in particular demand if the roof is equipped with a drainage groove.
Another method of stacking sheets is to make a block of 3 sheets. First of all, 2 sheets are laid on the first row. Between themselves, they are securely fixed, and the 3rd sheet of the 2nd row is joined last. This block can be fixed while aligning with the eaves.

Note! No matter which sheet stacking method you choose, it is important to pay special attention to each docking point. It is on this that the reliability and quality of the roofing will depend.

For each sheet of corrugated board, 7-8 self-tapping screws are required. They need to be twisted into the bottom wave. As mentioned above, the material is overlapped both vertically and horizontally. The overlap will depend on the angle of the slope. From what place should the sheets be laid? If the roof slope has a rectangular shape, then it is possible from any end along the cornice line. If the shape is a trapezoid and a triangle, then first of all it is important to think over the laying scheme. However, the first sheet is mounted in the center, and then the sheets are stacked symmetrically on both sides.

If a drainage system is planned, then the corrugated board is mounted along the eaves with an overhang of 60 cm. If it does not exist, then the overhang is carried out according to the material grade:

NS-20 - up to 10 cm.
S-44 and NS-35 - up to 30 cm.

So, align the first sheet along the cornice and the end of the roof. After that, it is fixed with a self-tapping screw at the top. Each next sheet is fastened along the longitudinal side of the sheet. It is pre-aligned with the eaves, and then fastened with the crate. According to this scheme, row after row is assembled.

The installation of the material is carried out so that a frontal overhang 7 cm wide is formed. At the cornice, the sheet is fixed at a distance of 30–40 cm, and the remaining rows of self-tapping screws can be staggered in increments of 1 m. . On a longitudinal overlap, fasteners are located at the top of the profile at a distance of 300 to 500 mm.

The next step is to install the ridge and the end plate. According to the standard, the end plate is 2 m long. If the length is not enough, then it overlaps. The fastening of the strap is carried out from the roof overhang to the ridge.

Note! When mounting the end strip, make sure that it overlaps at least one wave of the sheet. Self-tapping screws are twisted in steps of 1 m to the profiled sheet.

After that, it remains to make the last node of the roof - the ridge. Only smooth ridge elements should be used here. A number of experts recommend laying a special ventilated seal between them. If the sheets are corrugated, then a ridge seal is used.

At the end of the roofing work, a junction bar is installed with profiled sheets. They are an element with a length of 2 m. They overlap up to 20 cm. Fasteners are made with self-tapping screws from the side of the roofing sheets. Mounting pitch 40 cm.

Note! When organizing the adjoining of the roof to the wall, a special sealant should be used. It is laid between the joint strip and the upper edge of the corrugated board.

To prevent snow and rain from getting into the cracks, a longitudinal seal is also laid to the side junction. If the roof is steep, then such a seal is not needed.

In conclusion, let's summarize:

It is very important to pay attention to the transportation of roofing material.
The sharp edges of the sheets can cut your hands, so you need to work with protective gloves.
It is necessary for three people to lift the sheets to the roof. It uses two guides.
The installer must wear shoes with soft soles so as not to scratch the surface of the sheets.
If the surface is accidentally scratched, then these places must be treated with paint for polymer coatings.
You can step on the sheets only in places of the crate.

So, we are convinced that corrugated board is an excellent material for roofing. However, it is important to remember that it can serve for a long time and with high quality only if the installation and calculation technology is followed. If you have your own experience in this construction industry, then write comments at the end of this article. It will be equally useful to pay attention to the photos below.

If you are installing a do-it-yourself corrugated roof, then you need to think about the appropriate choice of rafters and battens, since these roof elements are often influenced by the type of corrugated board from which the roof is made.

Video about the installation of corrugated roofing on the roof with your own hands.

Depending on the type, size and area of the roof need to calculate the number of sheets of corrugated board and additional accessories that will be needed when installing the roof. However, a complex roof may require more sophisticated accessories than a simple gable roof.

Before starting the installation of corrugated board sheets, it is necessary to waterproof and vapor barrier the roof. For waterproofing, a special film is used, which is laid on the rafters and fastened with a stapler. Next, the crate is laid.

Since moisture can form between the roof and the waterproofing layer, it is recommended to place the crate on wooden slats laid on the waterproofing for ventilation.

How to fix corrugated board on the roof

How to fix corrugated board on the roof? For fastening corrugated board self-tapping screws are used on a wooden crate. Self-tapping screws are made of galvanized steel, and the steel contains a special stabilizer that prevents aging of the material from the action of ultraviolet radiation. Each self-tapping screw has a special sealing gasket made of elastomer. Such a gasket protects the wooden fasteners from rotting and the edges of the fastening hole from corrosion.

When calculating the required number of screws it is assumed that approximately 8 self-tapping screws are needed per 1 square meter of corrugated roofing.

Self-tapping screws are installed using a screwdriver. In this case, the screws are screwed into the lower wave of the sheet.

Fastening of corrugated board near the cornice is carried out with self-tapping screws located at a distance of 30-40 cm from each other. The following screws are installed through the wave, and the fastening pitch is 1 m.

Near the frontan, self-tapping screws are installed at a distance of 50 to 60 cm from each other. On the vertical overlap, the screws are located in increments of 30 to 50 cm.

screwdriver (set of suitable screws).

Tool preparation

NOTE!

It is strictly forbidden to use a grinder for cutting sheets of corrugated board. Bulgarians contribute to the burning of the polymer, and also contribute to the development of corrosion of the roofing material.

The structure and arrangement of the roof of corrugated board

- an important component of any roof. The design of the entire roofing pie consists of sequentially laid layers of materials that are required to provide heat, create a microclimate (humidity and ventilation systems) throughout the building. The device and method of laying the roofing cake depends on the purpose of the room.

For living quarters the layers of the roofing cake are laid in the following order, starting with the interior decoration of the room:

crate;
counterlattice;
space for air flow;

When arranging a roofing pie for non-residential premises, layers of insulation and vapor barrier are not laid. Air flow shafts and chimney outlets are equipped with a heat-insulating layer to prevent them from freezing.

Roof device from corrugated board: scheme

Preparation and installation of the crate

Before installing, it is necessary to determine the size of the crate step, measure the length, width of the sloping part of the roof.

Lathing step calculation

Boards are used to make the crate ( up to 5 cm thick) with a continuous crate or bars ( having a cross section of at least 5 cm by 5 cm) with a discharged crate. The type of lathing is determined depending on the angle of inclination (slope) of the roof.

The dependence of the step of the lathing on the angle of the roof

In addition, the material must be well dried. It is better to choose a tree of beech, pine or alder.

Lathing installation

The crate is installed on the rafters. To perform a smooth horizontal laying use a rope that is pulled parallel to the already laid board. Together with the rope, a pre-prepared template is used.

The height of the corrugated board profile affects the width of the crate step: the smaller , the smaller the crate spacing.

Start laying from the eaves. First, the main thicker board of the crate is fixed. Then the bars are laid from the bottom of the roof upwards in compliance with the step, or the boards are laid in a continuous layer.

Fasten boards preferably, nails or special brackets - a pair of nails per board, bars - to each rafter board - for one nail. It is recommended to use fasteners twice as long as the thickness of the board (beam) of the crate. The joints of the bars along the length must be fastened with staples or special nails. When the base of the roof is concrete, the crate is fixed with dowels.

Lathing installation

Protective boards are attached to the ends of the slope, equal to the height of the profile of the roofing corrugated board.

When the crate is completed, you should start laying the corrugated board.

The procedure for fixing sheets on the roof

It is important to fasten sheets of corrugated board with special self-tapping screws. If is less than 12° , then all joints of the sheets (having an overlap of at least 25 cm) are fixed with a sealant.

Instructions for laying corrugated roofing:

fastening of sheets with self-tapping screws is carried out strictly along the lower wave through one. In the lower and upper rows, each wave is fastened with screws;
when screwing in self-tapping screws, use low speed, since when pressed, the formation of a deflection of the material is possible;
when overlapping in one wave, a special rubber gasket should be used(with a roof slope of up to 16 °), while when applying a sheet in two waves, no gasket is required;
it is recommended to fasten the sheets to the crate with special self-tapping screws, having a color polymer coating and rubber ring gaskets, and between the sheets themselves - with special rivets;
end planks and ridge are laid after the application of the main coating of the entire roof.

Fastening with self-tapping screws

The last step corrugated roofing is, air ducts and adjoining strips.

The correct technology of laying the coating is the key to high-quality laying.

Overlap of corrugated board on the roof

For, to avoid roof leaks, it is necessary to correctly calculate the overlap details of roofing corrugated board.

The main indicator for calculating the overlap is roof pitch:

if the slope is less than 15°, then the overlap of the sheets must be at least 20 cm and at least two waves;
if the slope is 15°- 30°, then the overlap should be from 15 to 20 cm;
with a slope of more than 30° overlap width should be between 10 and 15 cm.

How to cover the roof with corrugated board

With a horizontal overlap, its width should be at least 20 cm. At the same time, all overlaps are sealed.

Do-it-yourself installation of corrugated roofing

Covering the roof with corrugated board can be done even by a beginner in the construction business, subject to installation requirements.

First of all, it is important to follow the instructions for the material, bought for the arrangement of the roof.

In addition, the choice of high-quality and certified material plays a big role in the quality of the future coating.

Mandatory stages of preparing the roof for laying the roofing profiled sheet:

correct and obligatory laying a waterproofing layer;
arrangement of ventilation by imposing slats on the waterproofing layer;
plank flooring on both sides of the gutter at a distance of about 60 cm under the valley plank on a crate with an overlap of 20 cm at the valley boards;
installation of a cornice strip, while the waterproofing layer should be higher.

Routing

Depending on the roof structure sheets of corrugated board are laid:

with a rectangular sloping roof. Installation of corrugated board on the roof is carried out from the lower corners of the roof. Lay several (2-3 pieces) sheets in the first row, securing them with one self-tapping screw. Then they mount the second row - 1-2 sheets of corrugated board. The rows are aligned along the cornice and fixed thoroughly;
with a triangular roof or a trapezoidal roof sheets of corrugated board are attached in two directions from the guide from the edge of the ridge perpendicular to the cornice strip.

Installation of additional elements

Fastening of corrugated board elements should be carried out in the following order:

the first sheet is placed in the lower corner roofs, taking into account the overhang (with a wave depth of up to 10 mm, the length of the overhang should be no more than 100 mm, in other cases, the length of the overhang should not be less than 200 mm);
parallel to the eaves overlap no more than two waves the following sheets are stacked;
second row of roofing sheets laid by applying a transverse overlap(about 20 cm) on the bottom row. Per square meter of corrugated board, from 6 to 8 self-tapping screws are required.

Further produced. The installation of the wind bar is carried out from the side of the hinged part to the ridge. The missing length is increased by overlapping the planks, and the excess is cut off. Thus, one of the waves of the sheet is covered with a plank. The bar is attached with self-tapping screws to both the end board and the corrugated sheets. At a low wave height of the sheets, a sealant is placed between the roofing material and the elements of the ridge.

Installing the wind bar

NOTE!

When installing ridge elements, the overlap must be at least 10 cm. The step of the slats should correspond to a length of 30 cm or more.

The installation of the roof with the wall is carried out using a ridge seal, which is mounted between the butt plate and the upper edge of the roofing profiled sheet. With a sloping roof, it is better to lay a longitudinal seal. With a steep steep slope - transverse.

Subject to the sequence of steps for installing roofing corrugated board, you can independently cover the roof with corrugated board with your own hands.

Common installation errors

Subject to certain nuances for the installation of corrugated roofing, mistakes should be avoided which can lead to serious consequences:

it is important to start laying the corrugated board from the correct edge. Having measured the edges, laying should be done from the edge with the smallest indicator. In this way, gaps in the overlap can be avoided;
when applying material stepping on the bottom layer should be avoided to prevent displacement;
do not align the sheets along the edge of the butt. A rope should be used as a level;
it is important to take into account the direction of the wind on the ground. Sheets laid against the wind are able to pass snow and rain flows.

Thus, the roofing from the corrugated board can be correctly laid both with the help of specialists and on your own. Compliance with the instructions and simple rules will help to cover the roof with high quality and provide reliable protection to the house.

In contact with

The roof is an important part of any home. It must be resistant to bad weather, damage of any type, temperature extremes. The aesthetic side of the issue also plays an important role. All these requirements are met by corrugated board, which is a versatile material with an impressive number of positive characteristics. A natural question arises, how to properly cover the roof with corrugated board with your own hands.

Profiled sheet and its main features

Today, many people decide to cover the roof with a professional sheet with their own hands. The product is not difficult to install and has a low cost. Profiled sheeting covers buildings with pitched roofs, gazebos and terraces, household objects of any value.

The profiled sheet is made of steel. In this case, the cold profiling technique is used. This results in a high level of strength and damage resistance. A huge role is played by the profiled sheet configuration, represented by stiffeners. The low price and variety of colors are additional advantages that allow you to worry about the attractive appearance of the house. You can cover the roof with a profiled sheet yourself, if you follow the features of the technological map and instructions. The correct execution of the roofing cake is also responsible for durability.

What is a roof structure?

The design of the roof truss system must be done correctly. Initially, a number of characteristics of the profiled sheet itself should be taken into account. First, it is, which is quite small. As a result, there is no need to strengthen the truss system.

The second important characteristic is the angle of inclination. It plays a more aesthetic role, so you can rely on your own preferences and wishes. The best option would be an angle of inclination of 12 degrees. If a smaller roof slope is chosen, additional work is needed. These include sealant treatment of all horizontal and vertical overlaps. In this case, the vertical overlap is mounted so that it represents two waves.

In order to cover the roof with corrugated board yourself, you must additionally use a wall (bearing corrugated sheet). When arranging a roof with an impressive angle, certain brands can be used, including the following S-44, NS-20, NS-35. With a small roof slope of 5-8 degrees, self-supporting products of the H-75, H-60 brands can be used.

In order to properly cover the roof with corrugated board, it is important to use a beam with a section of 30x100 mm to create a crate and install rafters, the average step is 1 meter. It is necessary to use a larger section if the step is more than one meter, and the minimum value for the step is 30 cm. The best material to create is an unedged board.

An important point is the humidity regime of the roof cake. For its organization, it is necessary to create a high-quality roof. To do this, waterproofing is placed on the rafters, a counter-lattice is fixed in order to achieve an optimal air gap between the waterproofing and the finishing metal coating. It should be remembered that before covering the roof, all wooden components should be treated with bioprotective and fire retardant compounds.

What is needed for self-assembly?

To cover the roof with corrugated board with your own hands, you should prepare a number of tools. Sophisticated equipment is not needed, and the list includes the following:

knife, rope, screwdriver, drill;
tape measure, pencil, level;
electric or cutting shears for metal;
construction gun, stapler, hammer;
sealant.

It is important to understand that corrugated board is not resistant to elevated temperature extremes. Welding is not recommended. You can choose scissors for metal, an electric jigsaw, a hacksaw with fine teeth. The technology of "cold" installation is also suitable.

How to choose seals and fasteners?

To properly cover the roof with corrugated board, you should give preference to fasteners of proper quality. Choose those that are made of steel, which is galvanized galvanized and qualitatively hardened. The element additionally has a neoprene rubber gasket to ensure the sealing of the mount.

Self-tapping screws are selected in accordance with a certain technical characteristic. Among them, the following are the most important:

Powder paint plays the role of a decorative and protective coating, the thickness of which should vary from 50 microns.
The surface is electrolytically galvanized, the thickness is over 12 microns.
Dimensions can be selected from three options - 4.8x80, 4.8x60, 4.8x35 mm.
The protection gasket is made of aluminum or elastomer depending on the area of use.
As part of the profiled sheet, stabilizers are necessarily present, which exclude the negative effect of UV rays.

Experts advise to cover the roof with corrugated board and fix it with self-tapping screws that match the color scheme. Today, picking up the details of the required shade is not difficult.

In this case, the roof covering with corrugated board is carried out using seals. Their material is polyurethane foam or polyethylene foam. Details are laid between the profiled sheet and the crate. The universal version has a rectangular cross section, but it is best if products that repeat the shape of a profiled sheet are used.

Covering the roof with corrugated board using sealants becomes an actual solution. As a result, the thermal insulation characteristics of the roof cake increase, and the service life of the floor increases. Sealers for corrugated board are extremely easy to install due to the presence of glue.

Covering the roof with corrugated board using seals will also be relevant when there is a need to eliminate gaps. In most cases, they occur when the corrugated board is adjacent to the roof plane. If the gaps are not closed, cold air, birds and insects will get inside. The advantages of the material include durability, resistance to bio-factors and moisture.

How to properly fix the profiled sheet?

In order to properly cover the roof with corrugated board with your own hands, you should learn how to correctly fix the profiled sheets. For this, a screwdriver is used, fasteners are screwed into the lower wave. On average, 7-8 self-tapping screws are needed per sheet of corrugated board. The profiled sheet is overlapped in accordance with the scheme. Neighboring profiled sheets reach more than one wave in size. Specific parameters depend on the slope of the roof and usually reach 100-300 mm.

The technology for covering the roof with corrugated board involves determining the place from where the laying will begin. For a rectangular roof, there are no particular difficulties, you can start fixing the corrugated board at any end, focusing on the cornice line.

For slopes of a trapezoidal or triangular shape, the layout scheme must be carefully considered. The main recommendation is that laying begins along the center line of the eaves, mounting the corrugated board in two directions symmetrically.

It is also necessary to take into account the overhang of the corrugated board. Along the cornice line, it should reach 60 mm if it is planned to organize a drain. If there is no need for a drainage system, then the overhang is increased, focusing on. For the S-44 or NS-35 grade, the overhang should reach 200-300 mm, and for the NS-20 grade, an overhang of about 100 mm will suffice.

The first profiled sheet is aligned along the cornice and the end of the roof, then it is fixed at the top. Then the corrugated board is leveled along the cornice and fixed along the longitudinal side, fastening to the crate. The following rows are mounted in the same way. Laying is carried out so that the front overhang in width reaches 70 mm. The optimal fastening step is 100 cm. If we talk about the gable of the roof, here the step is reduced to 50-60 cm, and at the eaves to 30-40 cm.

Such material as corrugated board has long been known to everyone and is used in construction in a variety of “roles” - fences are installed from it, garages and sheds are built, and roofs of outbuildings, small houses and even large mansions are covered. Decking is produced in a variety of colors, so you can see houses covered not only with sheets of the same color, but also with a combination of shades. which looks very original.

To know how to properly cover the roof with corrugated board, you need to carefully study the instructions, and then purchase high-quality roofing and consumables, prepare all the necessary tools.

It is very important that you do not need to have special professional skills to cover the roof with this material. The main thing is to follow the technological sequence of work and not make mistakes that can lead to roof leakage, which will require bringing the coating to perfection.

Advantages and disadvantages of corrugated board as a roofing material

Like any roofing material, corrugated board has its pros and cons that you need to know before purchasing it.

To positive qualities This material includes the following:

The light weight of corrugated board allows you to easily lift it to a height and, if necessary, level it at the installation site.
Optimum ratio of cost and service life of the material. With high-quality installation, the manufacturer sets a minimum operating period of 12 ÷ 15 years.
Ease of installation - the material is easily overlapped and screwed with special self-tapping screws.
Aesthetics of the coating - corrugated board, due to the variety of colors, makes the appearance of the house neat, gives it individuality.
In the relief of most sheet models, special capillary grooves are provided, which are designed to effectively drain water when laying overlapping sheets of material.

negative qualities corrugated board can be called:

High thermal conductivity of metal. Therefore, corrugated board will not protect the attic from overheating or low temperatures. If this coating is chosen, a good attic floor will be required, which implies additional costs for thermal insulation material and its installation.
In windy weather, when the wind speed is 15 m / s and higher, any metal coating emits ultrasonic vibrations that adversely affect the human psyche. Therefore, in regions with constant windy weather, it is better to give preference to roofing that does not vibrate in the wind.
Low soundproofing. If the roof is not provided with heat and sound insulating material, the sounds of drops or hailstones falling on the floor will be clearly audible in the house.

Choice roof decking

Decking can be made from galvanized metal sheets that do not have a color coating. Such sheets are most often used to create temporary or permanent sheds, or to cover outbuildings. It is also often used for building site fencing. Unpainted corrugated board has a fairly low cost, but is not very suitable for covering residential buildings, as it has low performance characteristics and is not very attractive in terms of aesthetics.

It is very popular, which has a decorative protective coating of polymer compositions. This material is more durable and able to withstand quite severe loads. Certainly this — with proper installation, which largely depends on the angle of the slope of the roof slopes.

Several types of corrugated board are produced with a protective and decorative polymer coating:

Bearing (H) - designed to cover the roof, floors and canopies.
Wall ( FROM) - used for the construction of a fence, hangars, garages.
Universal (NS) - suitable for roofing, installing fences, building garages, utility facilities, etc.

It is better to use a carrier to cover the roof, but last resort any of the above types can be used.

In addition, this material varies in height and number of waves. The height of the wave (corrugations) is indicated by a number, which is placed next to the marking of the type of corrugated board. For example, several models are presented in table:

Marking	Application	Corrugation height in mm	Metal thickness in mm	Usable width in mm
C10	wall	10	0,5; 0,6; 0,7	1100
C18	wall	18	0,5; 0,6; 0,7; 0,8	1000
C21	wall	21	0,5; 0,6; 0,7; 0,8	1000
	Roofing Wall	35	0,5; 0,6; 0,7; 0,8	1000
C44	wall	44	0,5; 0,6; 0,7; 0,8; 0,9; 1,0	1000
H60	roofing	60	0,7; 0,8; 0,9; 1,0	845

A metal sheet of corrugated board can have a one-sided or two-sided coating, but no matter what it is purchased for, it is better to choose a material that is protected on both sides.

The coating consists of numerous protective layers, the diagram below clearly shows which layers cover the outer and inner side.

External side of the roofing material:

The basis for corrugated board is a steel sheet.
Steel is coated with zinc.
Next comes the anti-corrosion coating.
A primer layer is applied to it, which serves as a preparation for the polymer.
Then comes the colored polymer coating.
A protective film (polyurethane) is often applied to the color polymer coating, which will keep it from fading and peeling.
For transportation and storage of corrugated board, it can be additionally covered with a film coating on top, which is removed after installation.

The inner side of the corrugated board is covered in the same sequence with exactly the same materials, but on some models there is no colored polymer film from the inside, while on others the sheet is covered equally on both sides. The latter, of course, have a higher cost, but their service life is much longer.

The color scale of a professional flooring is rather various. According to the most conservative estimates, the color range is represented by at least 30 shades, so choosing the right one will not be ore. The color layer on the surface can be applied by powder method or using a special polymer coating technology.

To summarize the selection criteria, we can list the following:

To make sure that the material is of high quality and produced in professional conditions, you should ask the seller for a product certificate. If it is missing, then it is better to contact another store.
The marking of the material is checked, indicating its purpose, thickness and wave height.
The appearance of the material is evaluated. It is necessary to pay attention to the evenness of the sheet, the absence of defects in the coloring and protective layer, the same shade of all sheets, the uniformity of the coating. The appearance can tell a lot about the quality of the corrugated board - if during the inspection a peeling of the coloring layer or burrs on the sections are found, then it is better to refuse the purchase.
Another criterion is to check the corrugated board for bending - high-quality material must be elastic, and if you try to bend it, it tends to return to its previous position. In this case, no trace of a fold should appear on the coating.
Type of external decorative coating - polymer or powder. The highest quality corrugated board coatings are matte and regular polyester and plastisol. Coating data must also be stated on the product certificate.
Material price. It must be remembered that you should not choose the cheapest material - it is unlikely to be of high quality. Moreover, all corrugated board has a very affordable price.

When the material is purchased, it is necessary to properly deliver it to the construction site, as well as carefully, without damage, unload and lift it to a height.

How to avoid damage during transport and installation of the material?

It is important to highlight this issue because damage to the corrugated board during its delivery, unloading and installation will significantly reduce the life of the future roof.

This material is made from steel sheet, which is embossed by cold rolling in special equipment.

Such material, laid as a roof, is able to withstand high wind and snow loads, but during its transportation, loading and unloading, the sheet coating can be subjected to unnecessary mechanical stress, which will lead to its damage. To prevent this from happening, you must follow certain rules for transporting, storing, carrying and lifting sheets.

Transportation of a professional flooring is made on trucks. The sheets must be stacked in piles on a rigid base of the body or on a special metal frame, which is fixed in the body at an angle.

After laying the roofing material in the car, it must be securely fastened with slings to avoid the sheets rubbing against each other when the car is moving, since this can lead to damage to the protective coating.
The car transporting the corrugated board must move at a speed of no more than 80 km / h.
It is very important to ensure that the unloading of the roofing is carried out with the utmost care. If unloading will be done manually, it is desirable that each of the sheets be removed from the stack separately, transferred and placed in the place prepared for them. It is best to prepare the flooring from boards and plywood, covered with polyethylene on top.
It is required to ensure that none of the sheets is bent during transportation, since it will not be possible to return it to its original state, which means that during coating, gaps form between the sheets that will violate the evenness and integrity of the roof.
To raise the corrugated board to the roof without harming it, you must also do it correctly:

- for accurate lifting of the material, logs will be required, which are installed at an angle to the roof - these will be a kind of "rails" for the convenience of lifting sheets;

- sheets rise to a height of only one piece;

- the laying of corrugated board on the roof itself can be done by two masters, but it is better to lift the roofing material to a height with three people - this is an additional insurance for the integrity of the material and the safety of work.

Now a few words about how not to damage the corrugated board during installation.

The maximum risk of damage to the material is added if a large area of the roof is covered, since in the process of laying and fixing it will be necessary to walk on the already laid roof. Therefore, it is necessary to choose the right shoes for work - it should not only be comfortable, but also have a soft elastic sole that cannot damage the protective layer and will not slip on the roof surface. It is possible to step on the fixed roofing material only between the ribs and only in those places where the guides pass, especially if there is a large step between them.

In order for the installation to take place neatly, without unnecessary damage to the roofing material, you need to use only high-quality tools. For work you will need:

Screwdriver.
Roulette.
Scissors for cutting metal up to 0.6 mm thick.
Marker for marks.
Level.
Electric drill.
Rubber mallet.
Electric jigsaw or electric scissors.
Soft brush for sweeping away metal shavings.

It is forbidden to cut the corrugated board with a grinder. The best tool for this is electric scissors.

Features of the installation of corrugated board as a roof

In order for the installation of roofing material to be successful, it is necessary to take into account some features of the work.

Influence of roof slope on installation

Much in the process of covering with roofing material depends on the slope of the roof. It is very important to correctly position the boards or lathing bars, as well as observe the required amount of overlap of corrugated sheets.

If the slope of the slope is 5 ÷ 10 degrees, then the crate is made solid or the slats are nailed at a distance of no more than 5 ÷ 7 mm from each other.

The overlap of the sheets in this case should be horizontally in two waves, and the top to the bottom row should be at least 300 mm. And with such a small slope of the slope, the gaps between the sheets of corrugated board are most often filled with sealant, since there is still a risk of water leaking between them, especially in windy weather.

With a roof slope of 10 ÷ 15 degrees, the distance between the lathing bars is 400 ÷ 450 mm, and adjacent sheets are overlapped in one wave. The top row should overlap the bottom row by 200 ÷ 220 mm.
With a roof slope of more than 15 degrees, the lathing bars are fixed on the rafters distance of 550 ÷ 600 mm. The overlap of the sheets stacked next to each other is made in one wave, and the top row is superimposed on the bottom row by 170 ÷ 200 mm.

To make it convenient to mark and fasten the crate, it is cut out to the right size, for example, 600 mm, which will help to mount the frame under the roofing much faster.

Order of fixing sheets

It is very important to follow the sequence of laying sheets if the coating will consist of two or more horizontal rows of corrugated board.

Laying of roofing material starts from the eaves. The edge sheet is set strictly according to the building level, since the correct laying of all other elements of the roof will depend on its evenness. In addition, the stacked sheets are aligned along the lower edge of the overhang - if this method of alignment is excluded, then the lower edge of the roof will be uneven.

Upon completion of the installation of the first row, fixing the second begins on the same side of the roof from which the first was mounted. However, some craftsmen also practice a different approach - with sequential laying of the bottom, and then the top sheet, or with the laying of a "ladder" - for example, two sheets from the bottom - one from above, that is, the top row constantly "lags behind" by 1 sheet.

The best option is if the length of the sheet is sufficient for the entire roof slope

If it is possible to purchase sheets equal to the length of the slope, then this option should be preferred - this will reduce installation time, and the roof will be more reliably protected from leakage, since there will simply be no horizontal overlaps of sheets.

Rules for fastening corrugated board

It is carried out using special self-tapping screws equipped with a press washer and a rubber gasket. To make the roof look aesthetically pleasing, self-tapping screws are usually matched to the color of the base material.

If the roof is covered with canvases that are solid along the length of the slope, then the first sheet is temporarily fixed at the top below the roof ridge by 50 mm and at the bottom, on the overhang. The sheet should protrude beyond the edge of the overhang by 40 ÷ 50 mm. The upper distance left open will become a ventilation gap and will later be covered from above with a ridge element.
The second sheet is overlapped with the first one or two waves, depending on the slope, aligned with the overhang of the first sheet and screwed with a self-tapping screw.

Subsequent canvases are laid and aligned also along the overhang and fastened together on the crest of the wave. Their fastening takes place from the eaves to the ridge with a screwing step of 500 mm.

When 3 ÷ 5 sheets of corrugated board are laid, and they are aligned along the edge of the overhang, their capital is fixed to the crate. The canvases are attached to the crate at the bottom of the wave, immediately after the overlap of the sheets, and then, passing one wave, along the bottom of the second.
If two or more horizontal rows are laid, then in the strip of their overlap with each other they are fixed with self-tapping screws along the bottom of each wave.

If polymer-coated corrugated board is installed, then after screwing in the screws, it is recommended to remove the formed metal chips in order to avoid damage to the protective coating of the roofing material. It is completely swept off the coating with a soft brush.

It is also necessary to stipulate the requirement that in no case can the corrugated board be fixed on the crate with nails or rivets, since such fasteners will not hold the canvas when a high wind load occurs. The wind can easily tear off the roofing, and the nails will remain in the bars of the crate.

Installation of additional elements

In addition to corrugated sheets, there are other elements in the roofing structure that help protect the building from the penetration of precipitation into the attic. It should be noted that the presence of even one formed or unclosed gap in the roof can seriously damage the ceiling, as well as the walls and ceiling of the house.

Additional elements of the roof include a ridge, valleys, lining of pipes passing through the roof, cornice boards and others.

Skate mount

After the installation of corrugated sheets is completed, at the highest point of the roof, its edges are covered with a ridge.

The ridge is fixed with the same self-tapping screws, through the top of the corrugated boarding waves, with a step of 200 ÷ 300 mm. In order for the fastening to become reliable, it is necessary to foresee two longitudinal boards on both sides of the ridge when installing the crate.

When installing the ridge, it must not be pressed closely against the highest point of the roof - there must be a ventilation gap between it and the inner surface of the ridge element.

If a semicircular type of ridge is installed, then special plugs are installed and fixed on its end sides.

Since the skate is assembled from separate elements, they are also overlapped. Simple skates, having the shape of an angle, should have an overlap of 120 ÷ 150 mm, and semicircular (tiled) - 100 ÷ 120 mm, with their alignment along the stiffeners.

Finishing the gable part of the roof from corrugated board

To exclude the possibility that the corrugated board will be torn off by the wind from the end side, the gap between the sheets and the crate is closed with wind angles or planks, which are superimposed on one side of the corrugated board, and on the other - on the first rafter facing the end of the building. The bar is also fixed with self-tapping screws with a pitch of 400 ÷ 500 mm.

Facing the end part of the roof. 1 - wind bar, 2 - self-tapping screws

Since the planks are also made up of individual elements, they are overlapped by 70 ÷ 100 mm.

Cornice fixing

The eaves are installed before the flooring of the main roofing material. It plays both a decorative role, closing the side connections of the truss system, and a functional one, preventing splashes from falling on the wooden parts when water flows from the roof into the drain. In addition, brackets are attached under the cornice or on top of it for laying the gutter.

Most often, at first, the drain brackets are fixed to the crate with self-tapping screws at a distance of 500 ÷ 600 mm from each other. They are lowered below the crate by 100 ÷ 150 mm.
Then the gutter is installed on the brackets.
After that, a cornice strip is installed and nailed or screwed to the bottom board of the crate.

Sheets of corrugated board are laid on top of the cornice strip, and must be leveled so that the water flowing from them directly falls into the fixed gutter

Valley installation

The installation of a valley is not required for every roof, but only where it has a complex configuration with profile fractures. If there is a conjugation of two planes, turned downwards, then mounting this element is indispensable.

The valley consists of two parts - internal and external.

The inner part of the valley is laid even before the roofing. It is fixed at the junction of two roof planes and fixed to the crate with roofing screws in increments of 350÷500 mm. Separate parts of a long valley are laid, starting from the eaves and rising to the ridge, with an overlap of 150 ÷ 200 mm.

After the sheets of corrugated board are laid (with a shift to the inside of the valley by 80 ÷ 100 mm), a layer of porous sealant is laid between them and the inside of the valley. This material will prevent leakage during rain. Then the corrugated board through the bottom of the waves with a step of 400 ÷ 500 mm, together with the lower part of the valley, is screwed to the crate with self-tapping screws.
After that, silicone sealant is applied to the edges of the sheets of corrugated board, and the outer part of the valley is laid on it. Just like the inner part, it is composite, so its parts are overlapped by 100 mm, starting installation from the eaves and anointing the joints with sealant.

After that, the outer part of the valley is screwed with screws to the corrugated board.

Fastening snow retainer

Snow guard- this is an element that will not allow a sharp descent of snow from the roof in the spring, delaying it and giving time to melt and drain with water or evaporate.

Snow guards There are two types - these are peculiar strips in the form of corners, scrolling in a checkerboard pattern, or horizontal tubular barriers installed in special brackets.

The brackets are attached to the corrugated board surface at a distance of 900 ÷ 1000 mm. Then, special tubes with threads along the edges are inserted into the holes in them, onto which, after their installation, metal plugs are screwed.

Both brackets and slats snow retainers fastened through the corrugated board to the crate. When fixing the planks, they are screwed through the top of the wave, so gaps are formed between the plank and the corrugated board, through which the melt water will leave.

Wall profile covering the joint between the wall and the corrugated board

If the corrugated roof is adjacent to the wall, then the joint between them must be closed to prevent leakage. For this, there is a special figured bar - a wall profile, which is mounted on the wall with the help of anchor fasteners, and on the metal profile - with self-tapping screws screwed into the crest of the wave.

Silicone sealant can be used to seal the junction of the plank with the wall. It is also advisable to make a strobe in the wall in order to hide the upper curved edge of this profile into it. After installation, the strobe can be sealed, for example, with cement mortar or tile adhesive for outdoor use.

Seals for corrugated board

Sealers are used in roofing to close gaps at the joints of the coating with the wall, at the places of “fractures” of hipped roofs and under the ridge.

Seals usually have an adhesive layer on one side, covered with parchment, which is removed before installation, and the material is glued in the right place.

Making the passage of the pipe through the corrugated board

If a chimney of a stove or fireplace, or a ventilation duct, passes through the corrugated board, you will have to work on it. But before do work on the external finish of the joints, it is necessary to install around chimney inner apron, which mounted before laying on the corrugated boarding crate.

An apron is installed around the pipe from separate metal adjoining profiles. On the walls of the chimney, using a marker, a line is marked along which a strobe will be punched to bend the upper edge of the adjacent profiles into it. Then it must be thoroughly cleaned of dust and rinsed with water.

After that, the so-called tie - stripe a metal sheet having flanges, which are mounted from the pipe to the eaves. A tie is needed to drain the water that accumulates behind the pipe during rain.

After that, the lower part of the apron must be fixed for sealant, on the crate and a tie laid on the sides of the pipe, and install the upper edge in a strobe, also on sealant. When installing the parts of the adjoining plank, they must overlap each other by 150 mm.

After the internal work is completed, the installation of corrugated board is carried out. When the roofing material is laid around the chimney pipe, the outer apron strips are mounted, which are fixed on the pipe and on the ridges of the corrugated board on the roof.

The general sequence of roofing with corrugated board

So, knowing how the installation of all additional elements and the corrugated board itself is carried out, we can consider the sequence of work on covering the roof with this roofing material.

The first step is to cover the truss system. It is laid from the cornice, horizontally overlapping the slope by 100 ÷ 150 mm. The film is fixed with a stapler with staples on the rafter legs.
On top of the film to the rafters are nailed bars of the counter-lattice, which will create the necessary ventilation gap between the film and the roofing material. The size of the bars should be 400 × 500 mm, that is, the ventilation gap will be 400 mm.
A crate of slopes is arranged perpendicular to the counter-lattice. Here it is necessary to provide additional ridge boards - they are located on both sides of the roof ridge. Also, additional boards or bars are mounted around the chimney and at the joints of the roof planes to secure the valley (angle inward) or ridge element (angle outward).
Further, wind boards are fixed on the gable sides of the roof.
Then brackets for the drain gutter are fixed on the bottom board of the crate, and the gutter itself is laid.
A cornice plank is nailed to the extreme board of the crate.
The next step is to fix the inside of the valley, if necessary in the roof structure.
Then you can proceed to the arrangement of the waterproofing of the chimney pipe. A tie is laid along its edges, going to the eaves - it is attached over the cornice strip. Next, install sealed elements of the inner apron adjacent to the pipe.
Having dealt with the internal additional elements, which should be under the roofing material, they proceed to the installation of corrugated sheets. To pass the pipe in one or two sheets, an opening of the required size is measured and cut out with the help of electric scissors. The edges of the corrugated board should cover the parts of the apron fixed on the crate and come close to the pipe. It is possible to leave a gap of 50 ÷ 70 mm.
Further, at the junctions of the two sections of the roofs, the outer part of the valley is fixed.
After that, metal elements of the ridge are fixed at the highest point of the roof.
The last step from the gable side to the corrugated board and the wind board is fixed windproof corner.

So, as you can see, there is nothing supernatural in laying such a roof. Having studied the sequence of work and the technology of their execution, enlisting the assistance of reliable assistants, acquiring the necessary material, preparing tools, you can safely start covering the roof with corrugated board on your own.
