Tools and accessories for corrugated roofing. How to cover the roof with corrugated board with your own hands. We select high-quality self-tapping screws

High-quality and durable roofing from corrugated board is quite easy to build on your own. It is only important to know what materials to take, how to properly attach the sheets to the crate and how to protect the inner under-roof space from dampness.

And we will pay special attention to additional elements that need to be bypassed with full compliance with the technology. So, do-it-yourself corrugated roofing - step by step!

Material preparation: avoiding the first mistakes

Once you have made accurate calculations for your roof, you can order profiled sheets. But, if you purchased corrugated board, but for some reason its installation will have to be postponed (for example, prolonged rains), then store the sheets without removing the factory packaging, on a flat surface and indoors. Additionally, bars should be placed under the sheets in increments of 50 cm.

Shift and move such roofing material carefully, holding the edges along the length and especially avoiding creases and deflections of the sheets. You also need to move the sheets carefully, because. modern polymer coating is particularly sensitive to mechanical damage.

As well as cutting this material with abrasive cutting tools: fragments from the circle will scratch, and significant heating will occur at the cut site. But, if you had to work that way, then immediately cover all the damage with repair paint.

Fortunately, the technology of roofing from modern corrugated board will allow you to carry out all the work in the warm season, from April to September, and you will not have to store the sheets for a long time.

Installation of corrugated board: step-by-step master classes

Let's first of all immediately deal with construction terms so that you do not have to search the Internet for the meaning of each new word:

You will be surprised, but the same (at first glance) material needs to be laid in different ways. It's all about the manufacturers - everyone gives their own recommendations for laying, and they are really important. Because corrugated board from different companies is demanding on its conditions, even if the differences are small. Therefore, carefully study the instructions attached to the roofing material and do not trust fully hired workers who “ate the dog on such roofs” and try to do everything their own way.

Here is a simple example of how the installation of corrugated board with a thickness of less than 0.7 cm and more durable differs:

And when working with such material, a wooden scaffold is no longer needed:

Imagine that a hired team starts stomping on thin corrugated board, because before that they “put the exact same roof on your neighbor” and “nothing bent”? And now it will bend, and how, to which the unfortunate workers will declare that "the way it was."

But, speaking in general, the main indicator of high-quality roof installation is tightness. After all, the roof just serves to protect all internal structures from moisture and cold. And even an inconspicuous gap can become a serious problem: dampness, smudges, quickly deteriorating materials and fungus. That is why we will now analyze in detail all the subtle points.

A little about safety

The technology of roofing with a metal profile is not as complicated as it is important not to damage the roofing during its installation. After all, although this material looks strong and tough, caution is still required when working with it:

On the finished metal profile flooring, move in soft shoes.
Try to step only on the concave waves of the sheets and better directly on the screws.
So, you can only step on the roof on your toes.
Keep your foot always parallel to the slope.
Only one leg should be in one recess.

Construction of a sheathing for corrugated board

The crate for mounting the roof is made either solid, if the slope is small, or sparse, in increments of up to 5 meters. But with what step the roof lathing is needed depends on how thick the sheets of corrugated board will be:

Waterproofing and wind protection

Next, we think about how to properly make a roofing roof pie. The modern market produces many waterproofing materials, of various types and properties. We even have a whole separate article about it. But in general, focus on the following program of action:

Step 1. So, fix the selected waterproofing material on the rafters. To do this, take the most common construction stapler, but before laying it, be sure to check whether you are laying the film or membrane on the wrong side. And glue the panels together with a special tape.
Step 2. After that, we break through the slats along the rafters (take a thickness of at least 2 cm) and thus form the ventilation gap necessary for ventilation.
Step 3. Now we put the roofing material on this upper crate.

Here's what it all looks like in real life:

We select high-quality self-tapping screws

The consumption of self-tapping screws when fastening corrugated board is usually about 6 pieces per 1 square meter. Self-tapping screws 4.8 by 28-35 mm are suitable, as for wood, and for additional elements - 4.8 by 50 or 60 mm. As a tool, purchase a screwdriver with a special nozzle or a cordless electric drill from the same manufacturers of roofing materials.

Special self-tapping screws for fastening profiled sheets are indispensable, because. This is the only way to ensure:

Complete waterproofing of the roof.
High connection strength.
The minimum risk of injury to the coating during fastening, and, therefore, the absence of corrosion in the future.

The highest quality and most reliable self-tapping screws for corrugated board are sold by the same suppliers that deal with sheets. Use zinc plated carbon steel or stainless steel screws whenever possible - this is ideal. But when buying, still carefully inspect all sealing washers.

How to properly fix the corrugated board?

You can understand that you have fastened the screw correctly by the metal washer - it will have about 1 mm of rubber gasket protruding.

It is necessary to screw the screws into the roofing material strictly perpendicularly, directly into the deflection of the vertical wave at the corrugated board. Although there are a lot of disputes about this in the construction fraternity, and each method has its own advantages. So, a self-tapping screw in the lower wave creates a more reliable fastening, and in the upper wave, rainwater is much less likely to get into the under-roof space.

On the eaves and ridge, you need to screw the screws into the deflection through the wave, and in the middle of the sheet - into each board of the crate. In total, you will need about 5-8 pieces per square meter.

What tools are needed for installation?

Note that the device of the roof itself from corrugated board is really within the power of even a person with little knowledge in construction. Of course, there are roofing materials that only experienced professionals can properly install. But in the case of modern corrugated board, we can reassure you: you can handle it yourself!

Fortunately, there is nothing complicated here. Due to the large length of the sheets, the roof slopes overlap without additional transverse joints, and the material itself can be easily cut and corrected. You will need a minimum of tools for this business:

So, you can lay corrugated board on slopes of almost any angle of inclination, it is only important to correctly calculate the amount of transverse overlap:

150-200 mm for roofs with 15-30°.
200 mm for slopes from 14°.
100-150° at large angles.

For fastening, you will need self-tapping screws with special sealing washers:

In what order should the sheets be laid?

Many roofers install profiled sheets like this: starting from the bottom row, they first lay 4-5 sheets, and each of them fix only one self-tapping screw in the center. After that, the sheets are interconnected with self-tapping screws 4.8x19 mm, which are installed in increments of 500 mm. Now they check how the sheets turned out to be aligned with the roof overhang, and finally fix the roofing material. Here is the scheme:

But, if you are working on the roof for the first time, in order to avoid distortion, fasten the profiled sheets in the same way, but in this order:

Step 1. We install the first sheet on the crate, and fasten it with one screw at the very ridge.
Step 2. We lay the second sheet so that the bottom edges of both sheets below form one perfectly even line.
Step 3. We fix the overlap along the top of the wave under the very first transverse fold.
Step 4. We evaluate by eye how correctly the sheets are docked. Uneven? Then lift one sheet from the other, tilt it slightly from the bottom up, and again join the fold by fold. Secure everything with self-tapping screws at the top of the waves.
Step 5. Work with 3-4 sheets in this way, carefully align them with the cornice and then install the remaining sheets.

To the base of the roof, the corrugated board must be mounted so that the edge extension is 40 mm from the eaves. This is necessary in order to leave a gap of the optimal size on the ridge and the ventilation of the roof was not disturbed. By the way, if the profiled sheets have a gutter, then each next one should overlap the groove of the previous one.

Remember: when laying, you cannot step on the comb of the sheets - they will bend. In general, fitters wear soft shoes for such work. That's all the details!

Working with additional elements

And now let's move on to our numerous additional elements. All of them, as a rule, are made in standard lengths: for a roof with a polymer coating - 2 meters, for a galvanized roof - 2.5 meters. They complete the roofing work themselves. The sealant, which is traditionally placed between the roofing material and additional elements, allows them to fit more tightly to the sheets, further preventing moisture from entering under the roof and allowing it to “breathe”.

But for the design of skates, cornices and other complex structures, you need to purchase special elements that are offered by the same manufacturer whose roofing material you purchased:

It is necessary to fasten the additional elements with the same 4.8 roofing screws as the main material. The only difference is that the metal roofing is fastened with self-tapping screws 28-35 mm long, and the elements - with self-tapping screws 50-60 mm long.

Valley and valley overlay

And now let's deal with such a mysterious name as "valley". The valley and the valley lining are additional elements duplicating each other, which are mounted at the points of internal convergence of two differently directed slopes. You need to fasten the valley under the corrugated board.

Therefore, if the roof has a complex shape, with internal surface joints, then take a valley and a valley lining as an additional element. So you will give your roof a neater and more aesthetic appearance, additionally protecting complex transitions from moisture getting inside.

Aprons for pipes

The most critical stage of the roof is the removal of pipes. Such pipes consist of two conditional parts - the lower one, which goes along the roof profile, and the upper one, the actual pipe. And, if the through passage of the pipe falls on the lower part of the roof, it makes sense to install a snow stop above the passage.

For a sewer ventilation system, an uninsulated pipe about 10 cm in diameter is passed through the roof, without a head. And for radon, they take the same pipe, but with a cap. Remember that these pipes cannot be connected to ordinary ventilation pipes, because. for those, insulated elements of 125 mm in diameter are already used.

The pipe itself can be installed both before the installation of the roof, and at the end. If you chose the second option, then in the finished roof you will need to cut a hole for the pipe and cover it with some material for a while. In the course of finishing work, pipe cuttings will need to be made from galvanized steel aprons or more modern materials such as Wakaflex.

Here is a good tutorial on how to do it:

dormer window

Now we are working with the dormer window. So, we cut the sheet of corrugated board into two parts at the lower end of the groove, put the bottom sheet, then the bottom plank of the groove, and only then the top roofing sheet.

snow holder

The snow guard is mounted in those places where there is a risk of snow rolling. For corrugated board, this is usually the second line at a distance of 30-40 cm from the eaves. For installation, use self-tapping screws 4.8x50 through 1-2 profile waves.

Outer and inner corner

If the slope changes its direction, then additional finishing elements are used, such as the inner and outer corner and the transition. Their main task is to create maximum tightness and give the joint of sheets an aesthetic appearance.

adjoining

The junction is an additional element that serves as a bypass for the chimney or protection of the roof adjoining the wall:

Cornice, end plank and joint plank

And here is the instruction:

Start the installation of the end strips from the side of the roof overhang, directing towards the ridge.
He already has an extra part of the end plate, just cut it off.
Fasten the plank to the end board and profiled sheets in the ox comb with screws in increments of up to 1 meter. If you did everything right, the end strip will cover at least one wave of the roof profile.
Attach the end plate with wood screws 4.8x60 or 4.8x50, directly to the wooden base. Leave a step from 30 to 50 cm and make sure that the end plate completely covers the end of the extreme wave of the corrugated board.

Now we move on to the installation of the connecting strip of the joint. Its length is 2 m, and the overlap of the planks cannot be less than 1 meter. The joint plank is taken 2 meters long, and two planks are attached to each other with an overlap of at least 1 meter. Attach the additional element to the wall in a strobe, or hide everything under the wall sheathing.

The main purpose of the eaves strip is to protect the under-roof space from precipitation, especially in rain with strong winds. And the lower the angle of inclination of the roof, the more necessary this additional element. But you need to fix the eaves bar earlier than the sheets of corrugated board. Overlap - 100 mm.

Installation of the skate

After all the roofing material has been laid, we fasten the ridge. In advance, we line the joints of the ridge and the roof with a sealant. Ridge elements for trapezoidal roofing sheets are usually taken smooth. Between them and profiled sheets, it is advisable to put ventilated seals, and for small corrugations - special ridge seals.

We fix the skate with screws on both sides at a distance of 2-3 waves. It is important that the ridge itself covers all the first screws that hold the sheets of roofing material. Ridge strips should overlap each other with a grip of at least 1 meter, and we fix the elements to the roofing sheets with self-drilling screws in increments of up to 3 meters.

An important point: the smaller the angle of inclination of the roof, the wider the ridge itself should be. So, the most standard dimensions are 140x140 mm or 200x200 mm.

But today it is more fashionable and rational to order a figure skate, which comes in two dimensions: 110x30x110 mm and 145x50x145 mm. There are also special types of ridge for a complex roof, when multidirectional slopes come together.

Roof care from corrugated board

Snow on the roof of profiled sheets lingers quite a bit, and therefore it is not necessary to clean it. But, if you need to carry out certain repairs, then arm yourself with small plastic shovels that will not leave scratches.

Caring for corrugated roofing is quite simple: the rain itself will wash away all the dirt and dust, and you just have to clean the grooves and drainage systems from clogged fallen leaves once a year.

If for some reason a more serious cleaning is to be done, then use ordinary water and a hose with a pressure of up to 50 bar. Detergents can be used only those that are intended for painted surfaces, and "White Spirit" will help to cope with stubborn stains.

As you can see, nothing complicated!

Building a country house is not an easy task. But what could be more reliable and cozier than a home built with your own hands?

When the walls are ready, it's time to build the roof. This is a crucial stage of construction, on which a lot depends. One of the modern and practical roofing materials, corrugated board, is easy to install and reliable in operation. How to independently build a roof from corrugated board?

Material selection

The professional flooring represents sheets of stamped galvanized steel. They are relatively light weight and bend easily. The profiled sheet can be coated with a special polymer composition that protects it from corrosion. Outside, the new sheets are covered with a protective polyethylene film, which is removed after the installation of the roof.

Important! The resistance of the metal to corrosion provides a protective zinc coating. According to Russian GOST standards, its indicator should be at least one hundred and twenty grams per square meter.

When mounting the truss system with your own hands, you need to know in advance what kind of roofing material you plan to cover it with. This is important because each coating requires a certain type of sheathing and rafter step.

When choosing a corrugated board, it is important to take into account the peculiarities of the local climate. For example, in regions with severe snowy winters, you need to choose a coating with a wave of at least 20 millimeters. The angle of inclination of the roof in this case must be at least fifteen degrees, otherwise the snow mass will linger and may deform the corrugated board.

The profile has several markings:

corrugated board C - with a wave height of 8 to 44 mm, used for light roofing or for decorative purposes, for the construction of temporary protective objects;
corrugated board NS - with a wave height of 35 - 44 mm, used for roofing, wall construction;
corrugated board H - wave height up to 114 mm, has additional stiffeners and is used for mounting ceilings between floors and capital roofing.

For the construction of the roof of a private house, the grade of corrugated board HC44 and HC 35 is considered optimal.

How to calculate the consumption of corrugated board

When calculating the consumption of material for building with your own hands, you need to take into account that the sheets are overlapped vertically and horizontally. In this case, the vertical overlap is equal to the wave, and the horizontal one depends on the slope angle. An angle of up to fifteen degrees requires more than twenty centimeters of overlap, up to thirty degrees - fifteen centimeters, more than thirty - ten centimeters.

Important! If the angle of inclination of the roof is less than 12 degrees, during installation, all seams must be treated with a special sealant.

The size of the cornice overhang depends on the brand of corrugated board. For HC8-10, it remains within 5-10 centimeters, HC 35 - H60 can reach 30 centimeters.

To calculate the consumption of corrugated board, you can use special programs that can make calculations for complex geometric shapes of the roof.

How to correctly calculate roofing materials:

Tools and materials for installation

Do-it-yourself installation of corrugated board does not require complex and professional tools. For this purpose you will need:

level, tape measure and rope;
knife, scissors for metal;
marker or chalk;
screwdriver, drill, stapler;
sealant in a tube with a gun.

Important! The metal profile is not resistant to high temperatures, so it is cut and installed without welding.

If there are no scissors for metal at hand, you can cut the corrugated board with a hacksaw or electric jigsaw. To protect the cut edge of the sheet, it must be covered with a special primer.

Self-tapping screws are used to fasten the corrugated board to the crate. They are made of galvanized steel and equipped with a rubber gasket, which will not allow moisture to penetrate through the mounting hole, and protect the wood from decay, and the corrugated metal from corrosion.

Advice! In order not to deform the sheets when they are lifted to the roof, you need to use logs. They are installed from the ground to the roof.

Logs will also help to avoid damage to the material during unloading and transportation.

Insulation and sheathing of corrugated roofing

Vapor barrier of corrugated roofing is carried out with a specialized film. You can use for this purpose and the usual roofing material. The main task of the vapor barrier material is to prevent excess moisture from accumulating under the roof. Sheets of hydro and vapor barrier are overlapped, attaching them with a stapler to the rafters.

Important! The installation of the film must be started from the lower edge of the roof, so that the upper row lies with an overlap on the lower one.

A crate is fixed to the insulating layer. Its density depends on the profile brand. If the profiled sheet is thin (grade C), the crate is made solid. For denser material, the pitch of the crate varies between five to ten centimeters. All wooden roof elements are treated with special protective compounds against fire, decay and insects.

Do-it-yourself installation of a profiled sheet

The laying of the profiled sheet begins from the lower edge of the roof, from the corner. The edges of the material should hang down by about 4-10 centimeters, depending on the brand of corrugated board. The first row is fixed on the crate with self-tapping screws. The fastener is screwed into the bottom of the wave. About five self-tapping screws are consumed per square meter of material.

At the corners of the roof, wind corners are used.

The overlap of the profiled sheets is done so that the waves match. The optimal horizontal overlap is twenty centimeters. If the roof angle is more than fifteen degrees, a sealant must be used. It is a gasket that does not allow snow, rain and wind to clog into the seams. The sealant must be selected depending on the waveform of the profiled sheet.

After mounting the main part of the roof surface, end and ridge strips are attached. Lastly, the corrugated board is attached to the walls and the chimney.

Important! Self-tapping screws on the sheet should not hang out. Properly installed fasteners do not deform the wave and are tightly fixed in the crate

If it is planned to install an organized drain on the roof, the eaves, gutter and plank are installed first. A perforated soffit is installed for roof ventilation.

The ridge on the roof must have two ventilation gaps. The ridge element is fixed with self-tapping screws with a distance of forty centimeters.

What is important to remember when installing a corrugated roof with your own hands

Any work at height requires special care and compliance with safety measures:

you need to use safety ropes and belts;
with a large slope of the roof, it is important to install a fence;
use shoes with soft, non-slip soles;
do not work in wet and rainy weather (profiling becomes slippery);
all work must be carried out with protective gloves, the sharp edge of the metal sheet can injure hands;
raising and lowering the profiled sheet should be carried out only along the logs with the help of three people, preventing the free fall of the material.

Reading time ≈ 4 minutes

The construction of a roof from corrugated board is considered the most affordable and simple method of arranging roofs in a private house. This building material is lightweight, resistant to corrosion, and any man can handle its installation without involving hired workers for the construction. Our tips will help you make a roof from a profiled sheet with your own hands and save money.

Preparing for installation

Before starting work, prepare the following materials and tools:

tape measure, level and knife;
drill, screwdriver, hammer;
construction stapler, metal scissors;
roofing screws measuring 4.8 × 35, 4.8 × 60 or 4.8 × 80 m;
wooden bars for crates;
profiled sheets.

Think about how you will be served sheets on the roof. To do this, you can use logs, winches or blocks. To avoid accidents, use special mounting belts and ropes for insurance and work in shoes that do not slip.

In order for a do-it-yourself corrugated roof to be durable and reliable, when choosing a brand of material, consider the climate of your area. Ideal option for roofs of private houses of any areas - a professional flooring of the HC44 and HC35 brands.

Framing and vapor barrier

1. Making the crate. For the crate, take wooden bars, they are lighter than metal ones and it is more convenient to mount them. You can take boards from spruce, pine, oak or alder. First, treat them with an antiseptic so that there is no fungus on the roof and a refractory compound. At this stage of the construction of a corrugated roof, it is advisable to mount special membranes necessary for vapor barrier. The crate is mounted on the truss system.

Consider the following points when installing the crate:

first, reinforce the first board along the eaves, which should be thicker than the others. Mount the board on special rails, pre-nailed to the rafter legs. The slats run perpendicular and are needed to provide the ventilation gap required for the corrugated sheet. Then continue attaching the rest of the boards. It is convenient to start fastening from the bottom, gradually rising to the top;
collect the construction of the crate using nails or self-tapping screws. For fixing boards to concrete, dowel-nails are used;
select the step between the bars depending on the angle of the roof slope and the size of the profile. Usually the step is 50-100 cm.

2. Vapor barrier. Vapor barrier prevents moisture from accumulating under the roof. This is a special film with membranes that release steam and prevent moisture from seeping through. Lay the film before you begin the installation of the corrugated roof roof. Lay the vapor barrier sheets overlapping, they are fastened with special self-tapping screws.

Features of laying a profiled sheet on the roof

Roofs for houses are single-pitched and double-pitched. A shed roof made of corrugated board requires less material and its construction is much simpler. Start fastening sheets on any roof from the bottom of the roof slope.

Main points of work:

all sheets are fastened to a wooden crate with roofing screws. Laying starts from the edge. If something is not clear, we recommend that you look at the photo and video of the installation of the roof, which you will find in our article;
screw the screws strictly perpendicular to the plane of the roof, distortions are unacceptable. Self-tapping screws are mounted in the bottom of the sheet wave. Each sheet will require 7-8 self-tapping screws, the installation of profiled sheets overlaps. The overlap of adjacent sheets must be at least one wave;
first, it is desirable to fix the profiled sheets with one self-tapping screw so that they can be corrected if it turned out not evenly. If the row is even, then securely fasten all sheets along the crest of the wave. The sides are sewn up with a special sheet after laying the entire row.

Profiled sheet (corrugated board) is made of steel sheet coated with zinc, aluminum and protective polymers. It is widely used in construction as a roofing material, for the construction of gates, fences and other structures.

The material acquires corrugation when passing through a roll forming machine, while the ribs of the sheet can be in the form of a wave or in the form of a trapezoid. The width of the corrugated board is 113-120 cm, the length is 30-1200 cm, the thickness is 0.4-1.2 mm.

Advantages of corrugated board

Before proceeding to the installation of a roof from a profile sheet, consider the advantages of the material:

Not subject to corrosion;
Long service life;
Ecologicaly clean;
Variety of colors and shapes;
High performance to environmental impact and mechanical stress;
During installation, a minimum number of joints is formed;
Universal.

The disadvantages include the formation of condensate and poor sound insulation.

Overlap of corrugated board and angle of inclination of the roof

In the case of using corrugated board as a roofing material, the installation of sheets must occur with an overlap.

If the slope exceeds 30 °, the overlap of the sheet will be 10-15 cm;
15°-30° - 15-20 cm;
less than 15° - up to 20 cm.

Calculation of roofing material

To correctly calculate the roofing material, you first need to calculate the area of \u200b\u200bthe roof, taking into account design features. To do this, the surface is divided into geometric shapes, all data is subsequently added up.
Each type of roof shape (triangle, trapezoid or square) uses its own formula to calculate the area. Eaves, end overhangs and kinks (ridges, ridges and junctions) are measured. Decking has two width indicators: total - 118 cm, and working - 110 cm, this fact must also be taken into account in the calculations.

To calculate the required number of sheets running horizontally, you need the length of the slope divided by the working width. The size of the overlap is also taken into account. The number and length of the sheets is equal to the sum of the overhang from the cornice, the overlap and the length of the slope.
2 meters is the standard length of the additional element, in order to determine the required amount of material, we sum up the length of the slopes, and then, taking into account 10 cm of overlap, divide the resulting figure by 1.9. To fix the corrugated board, self-tapping screws with rubberized gaskets are used, their number is 8 pieces per 1 m2. At the last stage, we determine the amount of insulation and waterproofing.

The device of a roof from a professional flooring

The indicators of thermal insulation, vapor barrier and waterproofing in the roof structure largely depend on the correct laying of the "pie". Roofing "pie" tout the entire structure of the roof. The system may be different, depending on the premises: whether it will be residential or not.
Pie device:

Decking;
Clapboard or drywall;
insulation;
Vapor-proof material;
crate;
Rafter leg;
Ridge seal;
Skate and rail;
Rafter bar;
Waterproof film.

The first sign of a violation of the roofing "pie" will be the formation of ice at sub-zero temperatures.

Tool and material for the installation of corrugated board

Film or thick polyethylene;
stapler;
Glass wool or mineral wool;
Silicone;
For gluing waterproofing seams connecting tape;
For waterproofing membrane in rolls;
Paralysis film;
self-tapping screws;
Screwdriver;
timber;
Clapboard.

The list of the required amount of building material is compiled when calculating the estimate, and will depend on the type of roof structure.

We properly cover the roof with corrugated board with our own hands

At the first stage of installation work, waterproofing is laid, starting from the lower edge of the crate. The film is laid with an overlap of 10 cm to 15 cm. The material should not be strongly stretched, and a construction stapler is used to fasten it.

Installation of the counter-lattice

Between the waterproofing and the corrugated board, it is required to leave a gap to remove moisture. The counter-lattice is installed after, the design consists of planks 5 cm high, they are placed along the crate, parallel to the eaves and rafters.

Installation of corrugated board

To ensure that the mounting hole is tightly closed, use self-tapping screws with sealing gaskets. Silicone sealant is used to process the horizontal overlap of the corrugated board.

If the installation takes place in a sloping roof, then the sheets are installed with a vertical overlap in two waves. In the case of using a sealing gasket, it is allowed to install sheets with an overlap in one wave.
Installation of corrugated board on a gable roof occurs from the bottom row. Lay 5 sheets and fix in the center with a self-tapping screw. And after that, with a step of 50 cm, the corrugated board is interconnected with self-tapping screws. If everything is verified along the overhang, then the final fixation is performed.

Installation of end strips

The end plate for most sheets is 2 m, the lowest installation begins with an overlap of 5-10 cm. If installed correctly, at least one wave of the profiled sheet will overlap. In increments of up to 1 meter, self-tapping screws are fastened.

The fastening of the ridge strip with an overlap of 10 cm is carried out with the help of smooth elements, they must be included in the kit. It is desirable to install a layer of air-permeable sealant between the corrugated board, fastening takes place in increments of 30 cm with roofing screws.

Installing the junction bar

With an overlap of 20 cm, an abutment bar is laid, fastening takes place with self-tapping screws in increments of 40 cm. Using a ridge sealant, the joints of the ends of the wall and roof are sealed, this will help to avoid moisture getting into the cracks.

The roofing process is considered high-altitude work, and safety measures must be taken before installation begins;
It is better to lay the corrugated board on the boards during the installation process, and not on the ground;
The corrugated board from the cornice should go down by about 5 cm;
The waterproofing should sag a little.
Use a taut cord to lay the profile sheets evenly along the cornice.

To protect the house from rain and snow, it is necessary to close it with a reliable roof. The roof covering is intended for protection of internal rooms from adverse atmospheric influences. Most often, a gable or four-pitched (hip) roof is used for private houses, but for small buildings, a single-pitched roof is possible.

A multifunctional profiled sheet can be used as a coating material. A do-it-yourself profiled sheet roof will allow you to complete the construction without unnecessary costs and loss of quality.

Pros and cons of roofing material

Installation of corrugated board on the roof is a fairly popular way to complete the building box. But before choosing this particular material, you need to familiarize yourself with its advantages and disadvantages. Knowing undesirable features, you can eliminate or smooth them out in time.

The advantages of the material include the following characteristics:

a shed or gable roof made of corrugated board with your own hands has a fairly low cost;
installation technology and transportation do not cause difficulties;
technology allows to provide high speed of roofing works;
light weight of the material;
strength and resistance to snow loads;
high degree of waterproofing with proper installation;
long service life;
resistance to corrosion and fading under the influence of ultraviolet radiation;
Fire safety;
with proper fixing, high resistance to wind loads;
the ability to use a sparse crate, which saves materials;
the presence of a variety of colors.

The list of positive characteristics is quite wide, but do-it-yourself corrugated roofing also has disadvantages:

laying the metal sheet makes the roof too noisy when it rains;
surface heating in the sun;
it is important to carefully lay the material, leakage is possible due to installation errors;
the appearance of corrosion in areas with a damaged top layer.

If you do the job correctly, the above problems will not arise. To reduce the noise level, soundproofing materials are placed in the coating cake. Heating from the sun in this type of roofing is not higher than in other materials. Unlike, for example, bituminous tiles, it does not lead to a change in the structure of the coating and its melting. If the installation technology is followed, there are no problems with leaks either, and in order to prevent corrosion, it is necessary to be careful during transportation and movement, to prevent damage to the profiled sheet.

Which profiled sheet to choose for the roof

There are quite a number of different types of corrugated board on sale. When buying material for a shed or gable roof, you need to pay attention not only to color, but also to technical characteristics, namely:

metal thickness;
profile type and height;
type of protective coating.

According to regulatory documents, there are three types of profiled sheet:

grade "H" with high bearing capacity for horizontal structures;
grade "C" for vertical structures;
brand "NS" - universal.

It is best to lay on the roof material of grades "H" and "NS". Grade "C" can only be laid in the roof cake on small buildings with a large roof slope (60 degrees or more).

It is also possible to lay a wall profiled sheet in a pie for a shed roof of garages. Also, when choosing, it is necessary to pay attention to the wave height of the sheet, it is indicated immediately after the letter in the marking. For pitched roofs, laying grades H60 and H75 is possible. For flat profiled sheets H75 or H114 are suitable. To choose the right one, you need to know the snow load and the pitch of the rafters.

Roof construction options

Depending on the purpose of the under-roof space, the pie of a shed or gable roof may differ. When arranging a cold attic or technical floor, the pitched roof structure will look like this:

rafter legs;
waterproofing;
crate;
roofing.

In this case, insulation is not required, as it is provided by the attic floor pie.
To equip an attic or a warm attic, you will need to lay the insulation. The roofing pie from the profiled sheet will look like this:

ceiling lining;
bottom crate;
vapor barrier;
rafter legs with insulation between them;
waterproofing;
wind protection;
counterlattice;
upper crate;
roofing.

The cake also largely depends on the chosen insulation. For example, laying mineral wool requires the arrangement of an air-ventilated layer. The thickness of such a gap should be at least 4-5 cm. This must be taken into account when choosing the thickness of the rafters and counter-battens. The insulated roof must meet the requirements of heat engineering, on the basis of which the thickness of the heat-insulating material is selected.

Step by step laying technology

The device of the roof from the profiled sheet

The device of a roof from a professional flooring demands performance of a preparatory work. They include measurements of the exact length of the slope and the calculation of the required number of sheets. The roof of individual buildings can be single-pitched, double-pitched or four-pitched. Most often, the length of the profiled sheet is taken equal to the length of the slope. In the calculations, it is necessary to take into account the margin for overlap, which depends on the angle of inclination of the surface:

200 mm or more for roofs with a slope of less than 15 degrees;
150-200 mm for roofs with a slope of 15-30 degrees;
100-150 mm for roofs with a slope of 45 degrees or more.

Having calculated the amount of profiled sheet needed to cover the roof, it is necessary to check the tools that may be needed. The device of a roof from a professional flooring requires the presence of:

rulers and pencils;
building level;
hammer and nails;
tools for cutting metal (metal shears, hacksaw, circular saw, electric jigsaw for metal);
riveting machine with steel rivets.

Having prepared all these tools in advance, you can easily lay a profiled sheet.

Choice of crate

The installation instructions for this element of the truss system are quite simple. Shedding for a shed or gable roof can be of two types:

solid;
sparse.

In most cases, both options are installed on the same roof. For the main area, the lathing is laid sparsely, and such roofing units from corrugated board as valleys, cornices, skates require laying without gaps.

The crate of a shed or gable roof can be made from the following materials:

timber with a section of 50 by 50 mm;
board with a section of 32 by 100 mm.

The dimensions also depend on the snow load and the pitch of the rafters. In the first case, the crate is laid every 5 cm, and in the second, every 10 cm (that is, every one). It is possible to lay more discharged.

All wooden roof elements must be treated with antiseptic compounds before work begins. After fixing the bars or boards (if there is no need for waterproofing), you can lay the roofing material.

Instructions for fastening sheets

Installation of corrugated roofing requires attention to the reliability of fastening. Sheets are fixed with self-tapping screws in the lower part of the wave. To properly cover the roof, you will need to prepare self-tapping screws with hexagonal caps and neoprene gaskets. It is necessary to use special high-strength fasteners designed for metal.

This video provides instructions for laying the profiled sheet:

The fastening technology is quite simple: sheets are fastened with self-tapping screws to the crate in the lower part of the wave so that there are 5-7 fasteners per square meter of coverage.

Also, before starting, do not forget to familiarize yourself with the important subtleties that professionals talk about:

Before you cover the roof of the house with corrugated board with your own hands, you need to carefully study the issue. If the structure is mounted correctly, there will be no problems with its operation in the future. The roof will not leak and will last for many years.
