This article will be useful for those who want to make a roof from corrugated sheets with their own hands. We will give step-by-step instructions that will help you do the roofing yourself without spending extra money on hired workers.

• If the roof slope is more than 15 degrees, the corrugated sheets should be laid on top of each other with an overlap of 200 mm.
• If the slope is from 15 to 30 degrees, the overlap should be the same or 50 mm less.
• It is advisable to use silicone sealants, especially if the roof slope is up to 20 degrees.

Before you begin to strengthen the corrugated sheets on the roof, you need to make a lathing.
It is most convenient to make it from wooden blocks. They are easier to install, and their price is significantly lower than their metal counterparts.

To make the sheathing, you can use beams made of alder, oak, aspen, spruce or pine. Before you begin installing the beams, they need to be treated with an antiseptic so that fungus does not appear on the roof in the future. The boards also need to be impregnated with a fire-resistant compound. At this stage of construction, special membranes can be installed that will protect against steam and moisture penetration.

Start of installation

First you need to install the upper and lower bars, located across. The structure can be assembled using nails or self-tapping screws if it includes metal elements. If the beams have to be attached to concrete, then dowel-nails can be used. It is most convenient to start installation from the bottom, gradually moving up. The step between the bars should not be more than 50 cm.

Vapor barrier

Vapor barrier is usually done on the roof of the building that will be heated. It serves to prevent moisture from accumulating under the roof. Most often, vapor barrier is a special film that has special membranes that prevent the passage of moisture and release steam. This film is installed before you begin laying the corrugated sheet. Vapor barrier sheets are laid overlapping, sticking to the roof with special self-tapping screws. You can make an overlap on the wall.

When the sheathing is ready and the insulation is done, you can install the corrugated sheets.

What is corrugated sheeting?

These are stamped sheets of zinc coated steel. They are quite light, able to bend, but at the same time durable. Thanks to these qualities, the sheets are excellent for roofing. Corrugated sheeting is suitable for any type of roof, regardless of how many slopes the roof has and what its slope is. They can cover residential and commercial premises.

Corrugated sheets are available in various sizes. They have different ribs and can be covered special enamel, or they can be without it. Don't forget to allow the film to sag a little. This is necessary to be able to ventilate the room. It is better to take the film together with which bitumen mastic can be used.

If you are using roll material- no big deal, but the sheets will need to be placed very tightly in relation to it. Laying the material will need to be done perpendicular to the location of the corrugated sheets.

How is a corrugated roof installed?

Before you start work, you need to take care of your safety, since the work takes place at height. In order to prevent accidents, you need to:
Use ropes for insurance and use special belts for installation.
If the roof slope is large, you need to do safety fence.
Use shoes with non-slip soles.
Do not install the sheets in the rain as they can become very slippery.
Shoes should not have hard elements. Stepping on the sheets can damage their protective coating. If possible, avoid stepping on them.

Damaged coating can be coated with a compound that is sold in construction stores for recovery protective coating sheets.

Direct installation

Most often, sheets of corrugated sheets are attached to each other with special self-tapping screws, which have a wide head with a rubberized skirt. If you use nails, they must be special: they are distinguished by a wide head and a rubber skirt. It is needed to ensure that the metal body of the nail does not scratch the corrugated sheet, and also to prevent moisture from entering the hole. The gasket can be made of polymers, but rubber is considered more reliable. It is best to treat the place where the screw is screwed in or a nail is driven in. sealant. The same is done with the seams that are formed from laying corrugated sheets on top of each other. This is done so that moisture cannot get under the sheets even at the molecular level.

If the corrugated sheet is too large and does not fit, the excess can be cut off using a hacksaw. You can use metal scissors, but they rarely cut accurately. Scissors are convenient for cutting small details, but not a big sheet. It's great if you have an electric cutter at your disposal. They can quickly cut perfectly even pieces, giving the sheet the required shape. Also suitable for this purpose circular saw, but you need to choose the right disk.

When cutting the sheet, do not use a grinder. This saw heats up the corrugated sheet material too much, causing the steel to become brittle and may begin to rust over time. Using this tool you will destroy protective layer sheet and ruin the insulation layer applied by the factory. This will lead to the fact that the corrugated sheeting will quickly become obsolete, and you will have to repair the roof, which begins to leak.
Sheet attachment point

How to attach corrugated sheets to each other?

Start installation from the bottom corner of the roof end. The bottom row is laid in such a way that its edges hang from the roof by about 4 cm. The first row is secured with self-tapping screws. The point where you need to screw in the screw is the bottom of the wave. Screw the screws into the waves one at a time.

When working with the sides of a building, you need to use wind corners, which are used to sew up the boards at the ends. Sheets can be mounted both lengthwise and crosswise, it depends on which method is more convenient for you personally. The sides need to be sewn up with a special sheet after you have laid the entire row. All sheets of corrugated sheets should be overlapped.
If the direction of the sheets is vertical, then the top sheet should cover the bottom sheet by at least 20 cm. If the wave pitch does not allow this, you need to overlap more, but in such a way that the waves coincide.
When placing corrugated sheets horizontally, the sheet located on top must overlap bottom sheet per wavelength. If you use a gasket-seal, it is better to overlap the length of two waves.
If the roof slope angle exceeds 16 degrees, it is necessary to use a sealant.

What is a seal?

This is a special gasket that is needed to prevent snow from getting stuck between the sheets of corrugated sheets. It also protects from wind and rain. The point is that the sealant forces the corrugated sheets to fit tightly to the sheathing. Seals are sold ready-made. You need to choose them based on the waveform of your corrugated sheet.

How to properly fix corrugated sheets on the roof?

Laying sheets should begin from the edge. One sheet is attached from the center of the edge using self-tapping screws. It’s better to secure it with one screw for now. This is done for the purpose of being able to correct the sheets. The following sheets are attached to it with an overlap and are also fixed with one self-tapping screw. This is done so that the row can be corrected if it turns out to be uneven. The sheets can then be secured securely.

After the row is corrected, you need to secure the sheets along the crest of the wave, and the joints are fastened with one self-tapping screw onto two sheets. This is done in each recess of the wave.

The first sheet is fastened in the following way: the longitudinal connection is made along the crest of the wave, the pitch is 500 mm, and the vertical joints are attached at each bottom of the wave.

The places where the screws are screwed are indicated in the figure.
For one meter square you will need about five screws. This consumption is the most optimal.
Installation of the ridge and end strips should be carried out only after the main sheet is securely fastened.

The most difficult thing is to install corrugated sheeting in places of contact with the wall. This part of the work is done last, like the installation of chimneys.
Pay attention to how the screw is tightened. Don't leave it hanging loosely, but make sure it doesn't bend the sheet. Correct location The self-tapping screw is shown in the picture.

Video - do-it-yourself roofing with corrugated sheets

To protect the house from rain and snow, you need to close it reliable roof. Roof covering is designed to protect interior spaces from adverse atmospheric influences. Most often, a gable or four-slope (hip) roof is used for private houses, but for small buildings it is possible to install a single-pitch roof.

Multifunctional profiled sheet can be used as a coating material. A roof made of corrugated sheets, made by yourself, will allow you to complete construction without extra costs and damage to quality.

Pros and cons of roofing material

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

The advantages of the material include the following characteristics:

• single slope or gable roof made from corrugated sheets with your own hands has a fairly low cost;
• installation technology and transportation do not cause difficulties;
• technology makes it possible to provide high speed 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;
• when properly secured, high resistance to wind loads;
• the ability to use sparse lathing, which saves materials;
• availability of many color options.

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

• laying metal sheets makes the roof too noisy when it rains;
• heating of the surface in the sun;
• it is important to lay the material carefully; the seal may be damaged due to installation errors;
• the appearance of corrosion in areas with a damaged top layer.

If the work is done correctly, the problems listed above will not arise. To reduce the noise level, soundproofing materials are placed in the coating cake. Heating from the sun for this type of roofing is no higher than for other materials. Unlike, for example, bitumen shingles it does not lead to changes in the structure of the coating and its melting. If the installation technology is followed, problems with leaks also do not arise, and to prevent corrosion, it is necessary to be careful when transporting and moving, to prevent damage to the profiled sheet.

Which corrugated sheet to choose for the roof

There are quite a large number of various types corrugated sheets When purchasing material for a single or double slope pitched roof it is necessary to pay attention not only to color, but also to technical specifications, namely:

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

By regulatory documents There are three types of profiled sheets:

• grade "N" with high bearing capacity for horizontal structures;
• grade “C” for vertical structures;
• brand "NS" - universal.

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

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

Roof design options

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

• rafter legs;
• waterproofing;
• sheathing;
• roof covering.

In this case, insulation is not required, since it is provided by the attic floor pie.
For arranging an attic or warm attic You will need to install insulation. A roofing pie made from corrugated sheets will look like this:

• headliner;
• bottom sheathing;
• vapor barrier;
• rafter legs with insulation between them;
• waterproofing;
• wind protection;
• counter-lattice;
• top sheathing;
• roofing covering.

The cake also largely depends on the chosen insulation. For example, styling mineral wool requires the arrangement of a layer ventilated by air. 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. An insulated roof must meet the requirements of heating engineering, based on which the thickness is selected thermal insulation material.

Step-by-step installation technology

Roof installation from corrugated sheets

The installation of a roof made of corrugated sheets requires preparatory work. They include measurements of the exact length of the slope and calculation required quantity sheets. The roof of individual buildings can be single-pitched, gable or hipped. 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 overlap margin, 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 corrugated sheets needed to cover the roof, you need to check the tools that may be needed. The installation of a corrugated roof requires:

• ruler and pencil;
• building level;
• hammer and nails;
• tools for cutting metal (metal scissors, hacksaw, circular saw, jigsaw for metal);
• riveting machine with steel rivets.

Having prepared all these tools in advance, you can lay the profiled sheet without any problems.

Choice of lathing

The installation instructions for this element of the rafter system are quite simple. Lathing for a pitched 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 sheathing is laid sparsely, and such roofing units made of corrugated sheets as valleys, cornices, and ridges require installation without gaps.

The sheathing of a single-pitch 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 lathing is laid every 5 cm, and in the second, every 10 cm (that is, every other). Possibility of styling more loosely.

All wooden elements Roofs 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 a roof made of corrugated sheets requires attention to the reliability of fastening. The 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 heads and neoprene gaskets. Special fasteners must be used increased strength, intended for metal.

This video provides instructions for laying corrugated sheets:

The fastening technology is quite simple: the sheets are fastened with self-tapping screws to the sheathing at the bottom of the wave so that for each square meter coating required 5-7 fasteners.

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

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

There are some nuances that require close attention, and neglecting these features can negatively affect the quality and functionality of the roof. Focus should be on the right choice roofing corrugated sheeting and compliance with installation techniques. Depending on the scope of use, profile sheets for roofing, wall and load-bearing purposes vary. For roofing installations, it can only be used roofing type corrugated sheeting, which can be of several types.

Types of roofing corrugated sheets

The roofing type of corrugated sheet most often has a coating of a special protective layer, represented by polymer materials– polyester, plastoisol or pural. Before purchasing roofing sheets, you should pay attention to the markings, which consist of letters and numbers.

The first letter in the marking reflects the purpose of the profiled sheet:

• the letter C marks wall sheets used for the manufacture of fences;
• the letter H marks high-quality roofing material;
• The letter NS marks a universal type of corrugated sheeting, the use of which can be used in the construction of roofing and wall fences.

For letter designation follows a figure that characterizes the wave height of the roofing sheet and is expressed in millimeters. The next number is the thickness of the metal sheet used in the production of corrugated sheets. The last two digits of the marking are the width and length parameters in millimeters.

High-quality roofing material must meet certain standards and for roofing it is allowed to use profiled sheets of the brands MP-18(A), MP-20(R), (A), NS-35(A), MP-35(B), S-44 (A), N-60(A).

Roof structure

Profiled sheets can be used for cold or insulated roofing. An insulated roof under corrugated sheeting requires special attention when performing the following steps:

Roofing pie structure

• layer of sheathing;

• ridge seal and ridge;

• laying waterproofing film;

• installation of a rafter strip or timber counter-lattice;

• installation of rafter legs;

• laying a layer of insulation;

• installation of vapor barrier film;

• ceiling rail device;

• installation of a layer of drywall or lining;

• arrangement of under-roof ventilation and ventilation between the insulation layer and the waterproofing film.

Installation technology

Installation of corrugated roofing can be done on a wooden frame or a frame made of steel purlins. Construction experts recommend using corrugated sheeting for buildings with a slope length of more than twelve meters. The application of several profiled sheets along the roof slope should be carried out with horizontal overlap and match the roof slope.

Instructions for laying corrugated sheets

Fastening corrugated sheets on the roof

Vertical installation of corrugated sheets can be started from any corner of the roof, but to avoid roof leaks, you need to cover the previous sheet with the next one by one wave. For high-quality ventilation, a gap of three centimeters must be left between the top roofing sheets and the thermal insulation layer. The material is invariably laid in a direction perpendicular to the horizontal cornice while maintaining an overhang of four centimeters.

Horizontal installation of corrugated sheets is justified if the length of the roofing structure is greater than the length of the purchased roofing material. Horizontal laying starts from any angle bottom row in the upward direction. The rule of overlapping the previous profiled sheet with the next one remains the same. The overlap of the joints should be twenty centimeters, and the remaining space is filled with silicone sealant.

The horizontal overlap should be:

• roof slope < 14˚ – двадцать сантиметров и больше;
• roof slope 15-30˚ - from fifteen to twenty centimeters;
• roof slope > 30˚ – from ten to fifteen centimeters.

If the roof slope< 12˚, то для герметизации горизонтального и вертикального нахлеста следует использовать тиоколовый или силиконовый герметики.

Roof elements

When using profiled decking, it is necessary to install the following roofing elements:

• The end strip, used for finishing the edges of corrugated sheets, is mounted before laying the corrugated sheets. Fastening by size or overlap is allowed. The first wave of the sheet is closed by an end strip by at least five centimeters. Side mount performed using roofing screws, and ridge fasteners are used for fastening from above;

• cornice strip protecting the facade of the building from precipitation. It is mounted with an overlap of ten centimeters. The attachment point is the last board of the sheathing. For fastening you should use roofing screws to match the color of the profiled sheet in increments of thirty centimeters;

• gutter strip, giving a finished and aesthetic appearance to the ridge element in front of which it is mounted. Using a strip and screws, the end parts of the corrugated sheets located under the ridge are secured;

• flashings in the form of external and internal corners, as well as abutment strips. They are attached after the installation of roofing sheets is completed. In addition to the decorative function, they help protect joints from moisture and dust. The place of installation of the abutment strips is the joints of the roof with walls and pipes;

• valleys connecting roof slopes with different slopes and promoting waterproofing. Installed before laying roofing sheets;

• snow guards mounted at a distance of thirty centimeters from the eaves edge. At length roof slope more than eight meters requires the installation of additional snow retention strips;

• ridge connecting top sheets pitched junction. Acts as protection for the upper line of the roof fracture. The mounting location is the top points of the corrugated sheet waves. Installation required sealing tape between the roofing sheets and the ridge, as well as filling the seams with sealant.

Correct fastening of sheets and components

Self-tapping zinc coated screws must be used to hold the roofing sheets together and to the sheathing. In addition, sealing washers made of neoprene rubber are used. Fastening the corrugated sheeting to the sheathing through the lower part of the corrugation is carried out with self-tapping screws 4.8-28 or more.

The ridge is fastened through top part corrugations with a self-tapping screw, the length of which is commensurate with the height of the profile.

The wind strip is attached using self-tapping screws in increments of 20-30 centimeters and an overlap of 10-15 centimeters.

The overlap for the ridge elements is 10-20 centimeters, and for fastening they are used through the upper part of the corrugation in increments of 20-30 centimeters. The length of the fasteners depends on the height of the corrugated sheets.

Cost of work

The average price for the installation of a pitched roof using sheets of corrugated sheets, excluding the cost of the material:

• installation of roofing covering on ready-made sheathing - from 700 rubles per m²;

• installation of roofing with installation of sheathing on a finished rafter system - from 950 rubles per m²;

• installation of a pitched roof with cold attic space, including rafter system, lathing and covering made of corrugated sheets - from 1,500 rubles per m2.

For more information on how to install it yourself, watch the video.

Let's sum it up

Modern roofing sheeting is becoming very popular. This material is especially in demand in the private sector and low-rise construction. The availability of an affordable price and performance qualities equivalent to a metal tile coating has made corrugated sheeting a very attractive material for roofing, which correct installation will serve faithfully for many years.

In this article we bring to your attention detailed guide for installation of a corrugated roof. After studying the technology of work and watching a thematic video, every homeowner will be able to correctly lay and secure the roofing with their own hands.

Installation of roofing from corrugated sheets

The first step is to select a brand of profiled sheet suitable for roofing. There are products on sale with the following markings:

• C – low profile material for walls and fences;
• H – sheets with an increased profile and stiffeners;
• NS, MP, MK – universal corrugated sheeting.

Reference. An example of complete marking looks like this: H60-845-0.5. The number 60 indicates the height of the profile in mm, 845 – the width of the sheet, 0.5 – the thickness of the metal.

The division into wall, roofing and universal corrugated sheets is quite arbitrary. Therefore, when choosing a coating, adhere to the following recommendations:

On a small country house or the garage will use galvanized metal without a polymer coating, it is significantly cheaper. To independently cover a private home or bathhouse with colored corrugated sheets, prepare additional materials:

Important point. Immediately exclude the grinder from your toolkit. Powder-coated metal can only be cut with electric or manual scissors.

Lathing requirements

Before covering the roof with corrugated sheeting, it is necessary to install the rafter system and prepare the sheathing. What should be done:

An important question is the step of laying the slats into which the corrugated sheet will be screwed. The interval depends on the slope of the roof: the smaller the angle, the greater snow load and boards are put up more often. It is recommended to maintain the following distances between the slats:

• slope less than 10° — continuous lathing or step up to 10 mm;
• roof angle 10-15° - interval no more than 45 cm;
• tilt over 15° - installation step of boards is 60 cm.

Advice. Adjust the distance between the slats to the length of the profiled sheets to securely fasten them at the edges.

Under the lining of valleys providing drainage large quantity water, it would not hurt to add additional waterproofing from roofing felt. In the case of insulated mansard roof do not forget to provide ventilation of the under-roof space, as shown in the diagram.

Installation instructions

Before you start covering the roof with corrugated sheets, you should install the internal shaped elements. These include valleys and chimney pipe framing - the edges of these parts must be covered with corrugated sheets on top.

The chimney is lined using the following technology:

It is easier to cover the drains in the corners with valleys - attach the shaped parts to the sheathing, starting from the cornice. The pitch of self-tapping screws screwed along the edges is 30-40 cm, the amount of overlap of the upper parts on the lower parts is 300 mm.

Now about how to cover correctly roof structure with your own hands:

Note. Corrugated sheeting can be laid either in rows or as a “ladder”, so that you do not have to constantly move the stepladder. The principle is simple: put 3 sheets in the 1st row, 2 in the second, one in the 3rd, then move to the side and continue installation, starting from the cornice.

After covering the entire area of ​​the slopes, all that remains is to attach additional parts (flashings), which cover the gaps from precipitation and give the roof a finished look. Let's list these works:

Installation of solid sheets of custom length is much easier - you need to maintain a side overlap and clearly align the sheets before fastening. To avoid damaging the powder paint when lifting long elements, it is recommended to tie them to wooden frame or use more modern devices - construction suction cups and clamps.

How to properly cover a roof with corrugated sheeting is demonstrated in the video:

Pros and cons of profiled coating

If you decide to cover your roof with corrugated sheets, you should be aware of the advantages and disadvantages of this material. The advantages of profiled painted sheets include the following qualities:

• reasonable price of building materials (cheaper than metal tiles);
• relatively light weight;
• ease of processing and installation compared to other traditional coatings;
• wide choice of colors;
• service life is from 15 to 30 years.

Note. Galvanized corrugated sheets without a colored coating are cheaper than painted ones. The material is well suited for various outbuildings and other ancillary buildings at the dacha.

Judging by reviews from homeowners, the operational drawback of steel profiled sheets on the roof is “sonority.” Even with insulation and sound insulation, the coating always “notifies” the owners of the house that rain has begun by the dull thud of drops on the iron. Other disadvantages look like this:

1. Metal conducts heat well, protecting attic space from the wind. If the roof is not insulated, the attic will be quite cold in winter, and too hot in summer.
2. The polymer coating fades in the sun and loses appearance after 3-4 years of operation.

Conclusion

Since the advantages of corrugated sheeting outweigh the negative aspects of its use, the material is in demand among homeowners with low incomes. Polymer-painted sheets allow you to save on installation if you do it yourself. As you can see, this task is completely solvable.

Durable quality roofing You can quite easily build it yourself from corrugated sheets. It is only important to know what a corrugated sheet roofing system is, as well as how to attach these sheets to the sheathing, and how to protect the internal under-roof space from moisture. Special attention It is also necessary to pay attention to additional elements, which must be used in full compliance with technology.

Preparation of material

After you have completed all exact calculations roofs, you can already order profiled sheets. If you have already purchased the sheets, however, their installation must be postponed for some reason, for example, because of rain, then the sheets must be stored without removing the original packaging from them, in indoors on flat surface. Additionally, it is recommended to place beams under the sheets at a distance of 50 cm.

This covering material must be moved and rearranged quite carefully, holding it by the edges along its length and especially avoiding deflections and creases in the sheets. Corrugated sheeting must be moved carefully, as modern polymer coating considered particularly sensitive to mechanical damage. It is necessary to cut the material abrasive cutting tools: fragments from the circle can severely scratch your hands, and significant heating is observed in the cut areas. If this is still necessary, then all damage must be immediately covered with repair paint.

Fortunately, the technology for constructing a roof made of corrugated sheets currently allows all installation work to be carried out in the warm season, from April to October, then the material will not have to be stored for a long time.

Step-by-step installation master classes

This will surprise some, but the same, at first glance, material must be laid in different ways. It's all about the manufacturers, because each manufacturer gives their own recommendations for installation, they are really important. Profile sheets from different companies demanding of their conditions, even if these differences are small. Therefore, you must carefully study the instructions supplied with the roofing material, and also not completely trust hired workers, who want to do everything their own way and “the dog was eaten on such roofs”.

Thin metal profile

If for installation of the roof you select a profile whose thickness is less than 0.7 mm, then during its installation you cannot move directly on it, as this will lead to damage. Therefore, you will have to lay wooden scaffolding on which you will need to walk.

Step by step instructions:

Roofing with corrugated sheets

When working with such material wooden backing can no longer be used.

Master class on installation of metal profile roofing:

The main indicator high-quality installation roofing is its tightness. The roofing material serves precisely this purpose, to protect all internal structures from moisture and cold. Even a small gap can become a serious problem in the future, allowing dampness and leaks to pass through, which can lead to to the formation of fungus and material damage.

Wind protection and waterproofing

Currently the market can offer large selection a wide variety of materials that will differ in types and properties.

Wind protection and waterproofing involves the following actions:

Step-by-step installation of waterproofing under corrugated sheeting:

Laying order of sheets

Most roofers install corrugated sheets in the following way: start from the bottom row, lay four sheets first, and each of them is fixed with only one screw located in the center. After this, the sheets are connected to each other with 4.8 × 19 mm self-tapping screws, which should be installed in increments of 50 cm. After this, you need to check how much metal sheets turned out to be aligned with the roof overhang, and then finally fix the roofing material.

If you are installing a roof for the first time, in order to avoid distortion, the profiled sheets must be attached in the following order:

The corrugated sheeting must be mounted to the base of the roof so that the edge offset is 4 cm from the eaves. This must be done in order to leave a gap in the skates. optimal size, and so that roof ventilation is not disturbed.

High-quality screws

The consumption of self-tapping screws during installation of a corrugated roof is usually about 6 pieces per square meter. For such installation, dimensions 4.8 × 28−35 mm are suitable. These screws can be used for both wood and metal. From manufacturers roofing materials You can also purchase screwdrivers with a special attachment as a tool. You can also use a cordless electric drill.

Special self-tapping screws for roofing with your own hands are indispensable, since this is the only way to ensure:

• High connection strength.
• Complete waterproof material.
• There is minimal risk of mechanical injury to the coating during fastening, which means that this will indicate the absence of corrosion in the future.

The most reliable high-quality self-tapping screws can be purchased from the same suppliers who sell corrugated sheets. It is recommended to choose screws made from stainless steel or carbon steel with a zinc coating. When purchasing these items, you still need to carefully inspect all sealing washers.

Correct fastening

You can tell whether you have fastened the screw correctly or not by looking at the metal washer - it should protrude rubber gasket by about 1 mm.

It is necessary to screw the screws into the corrugated sheet strictly perpendicularly, directly into the deflection of the vertical waves. Although many builders debate this issue, each method has its own advantages. For example, a self-tapping screw in the lower wave creates the most reliable fastening, and in the upper wave rainwater has less chance of penetration under the roof space.

But manufacturers recommend fixing the corrugated sheet exactly in the deflection. On the ridge and eaves you need to screw screws into the sag through the wave, and in the center of the sheet they need to be screwed into each sheathing board. In total, each square meter requires approximately 5 to 8 screws.

Required Tools

It is worth noting that the installation of corrugated sheeting on the roof is truly accessible even to a person with little experience in construction. Of course, there are roofing materials that only experienced professionals can install correctly. But if we consider the case of modern corrugated sheeting, then everyone can cope with the installation on their own.

Thanks to long length With corrugated sheeting, the roof slopes overlap without any additional transverse joints, and this material can be easily adjusted and cut. The following tools will be needed for installation:

The profile can be laid on slopes of almost any angle of inclination; in this case, it is only necessary to correctly calculate the amount of transverse overlap:

• 100−150 - mm at large angles.
• 200 mm - for a slope of 14 degrees.
• 150−200 - mm for roofs with 15−30 degrees.
