What is a profiled sheet and how to cover a roof with it
Thanks to the development of advanced technologies, new materials have appeared in construction that have high performance characteristics and an affordable price. High-tech building materials include corrugated board - galvanized corrugated metal sheets of various sizes with or without polymer coating.
Sheets of corrugated board of various colors and with different corrugation heights
From the outside, the profiled sheet consists of the following layers:
- galvanized sheet - the basis of the profiled sheet;
- anti-corrosion coating;
- polymer coating;
- protective mounting film.
On the inside, the sheet can also be protected with an anti-corrosion layer and protective varnish.
The advantages of using profiled sheets in construction
Due to its high protective characteristics and aesthetic qualities, the profiled sheet is simply irreplaceable when arranging the roof. The convenience of using this material also lies in the fact that wall cladding, the installation of fences and roofing with a profiled sheet can be done by hand. On numerous specialized sites there are videos and photo instructions on how to cover the roof with profiled sheets.
High strength, anti-corrosion properties and rigidity, combined with a variety of sizes and low weight, ensured the popularity of corrugated board in the construction of various types of premises.
Even a non-professional can lay professional sheets
The main advantages of using a profiled sheet include the following:
- durability;
- resistance to corrosion;
- rigidity;
- light weight;
- versatility;
- ease of self-assembly;
- availability of component materials;
- ease of transportation and storage;
- low price;
- wide range of sizes;
- high aesthetics of the coating.
Corrugated roof is not subject to corrosion
The use of a profiled sheet speeds up the time and total cost of building with your own hands. A small number of joints ensures reliability and tightness of the structure, and a low weight allows even beginners to fasten the profiled sheet.

After entering the construction markets for profiled sheets, roofing work with this steel material is much faster and easier. A large amount of information, photos and videos on how to cover the roof with a corrugated sheet with your own hands, allow you to learn how to fix a roof from corrugated board yourself.
Like many repair work, it is best to cover the roof with a profiled sheet together. First, it is necessary to clarify the size of the area that needs to be covered with corrugated board, make sure the rectangular shape of the slopes and check their plane using a level. Then decide on the color, shape, thickness and brand of the profiled sheet, as well as select the necessary tools and accessories.
Types of professional sheet, selection and marking of corrugated board
A variety of types, shapes and a wide range of sizes of profiled sheet for the roof make it possible to find the right material for any roof.
Profiled sheet with a capillary groove
Profiled sheets differ in the height of the corrugation, the presence of a capillary groove and a variety of colors of the polymer coating. The corrugation shape of the corrugated board is trapezoidal and sinusoidal, less often a rounded and rectangular sheet is found.
The capillary groove is necessary to drain moisture from the roof when overlapping profiled sheets, and the polymer coating provides a protective and aesthetic function. Due to the variety of colors, you can assemble a roof of any color with your own hands, giving a special personality to the home.
Important! All information about the professional sheet is reflected in its marking. For the roof, corrugated board with lettering marking is used H - carrier, and the next row of numbers means a number of characteristics.
Profiled sheeting marking: H - for roofing (installation fixed formwork, as interfloor floors), С - for wall fences and partitions, NS - for roofing and wall fences
For example, corrugated board is marked H-60-0.7-840, which means:
- roof sheeting;
- corrugation height 60 mm;
- metal sheet thickness 0.7 mm;
- assembly width of a sheet is 840 mm.
The choice of the profiled sheet is made depending on the purpose of the building under construction and the climatic conditions of the area. Unheated premises, barns, hangars and other ancillary buildings can be covered with inexpensive galvanized corrugated board without polymer coating. Residential buildings, where the angle of inclination of the roof is more than 10 °, must be covered with a profiled sheet with a polymer coating, a large metal thickness and high corrugation.
To fasten the profiled sheets, use self-tapping screws to match the color of the roof
Important! When choosing a professional sheet, pay attention to its appearance. The surface of the material must be smooth, without cracks or scratches, with an intact protective film.
An important parameter when choosing a brand of profiled sheet is the slope angle. The greater the slope angle, the larger the roof surface, the higher the windage, but the lower the snow load, since snow easily rolls off the sloping roof. In order to avoid deformations, the roof of a slight slope must be covered with a profiled sheet of greater thickness.

Required tools and materials
Before you cover the roof with a profiled sheet with your own hands, you need to decide on the tool and purchase the appropriate materials. For self-installation of roofing from corrugated board, you must have the following:
- cordless screwdriver;
- construction stapler;
- electric shears and a hacksaw for metal;
- building level;
- roulette;
- markers of different colors;
Tools for mounting profiled sheets: 1 - screwdriver, 2 - hammer, 3 - rubber hammer, 4 - metal brush, 5 - tape measure, 6 - rail, 7 - marker, 8 - water level, 9 - scissors for metal, 10 - round nose pliers
- gun with sealant;
- drill with a set of drills;
- self-tapping screws with a sealing washer;
- skate for connecting sheets;
- a metal brush for removing shavings;
- wind bar from rainwater;
- snow holders on the roof made of profiled sheet.

Work stages and material calculation
The main stages of do-it-yourself roofing using professional sheets are:
- roof design;
- installation of the lathing;
- determination of the size and quantity of the profiled sheet;
- determination of components and additional elements;
- installation of a profiled sheet on the roof of the roof;
- installation of wind bars, ridge and snow guards.
Before you cover the roof with a profiled sheet, you need to decide on the project. This can be done using specialized construction programs or you can calculate it yourself. If you have to cover a complex roof with many slopes at different angles of inclination, it is best to use ready-made programs or turn to architects. With a simple design, the question of how to cover the roof with a profiled sheet without a special program is solved by ordinary mathematical calculations.
Roof prepared for laying corrugated sheets
Material calculation
The basic formula for calculating the number of profiled sheets to cover a simple roof is as follows:
N=D/L,
Where N is the number of profiled sheets for laying a horizontal row, D is the length of the roof slope, L is the useful (assembly) width of the sheet. In the final calculation, the parameter N is rounded up.
Important! Speaking about the dimensions of the profiled sheet for the roof, it must be borne in mind that the calculations take into accountnot general, but working, that is, the useful width of the sheet. In this case, the overlap of the material is equal to the difference between the total and useful width of the sheet.
For a simple roof, the number of required profiled sheets can be calculated independently
The size of the horizontal overlap depends on the angle of the slope and is determined according to a special table:
| Ramp angle | Up to 15 degrees | 15 - 30 degrees | More than 30 degrees |
| Overlap | 20 cm and more | 15 to 20 cm | 10 - 15 cm |
The vertical overlap depends on the brand of the selected corrugated board and must be covered with overlapping waves.
The brand of corrugated board plays a significant role in determining the size of the overhang: the greater the height of the corrugation, the longer the overhang should be. With a short overhang, water can flow under the roof.
After determining the number of horizontal profiled sheets, you need to calculate how many such rows are needed to cover the roof. This value is calculated based on the length of the roof slope, eaves, roofing sheet, the size of the overlaps, as well as taking into account additional elements.
Installation of crate for corrugated board
How to attach a profiled sheet to the roof. DIY installation features
Before you start fixing the corrugated board with your own hands, it is advisable to view the corresponding training videos and photographs. Roofing with a profiled sheet must be started after installing the end boards, from the bottom row, taking into account the size of the overhangs. The end plate of the profiled sheet (wind angle) must subsequently be attached to the upper end board. Then, using self-tapping screws, install the cornice strip.
Roof preparation scheme for laying profiled sheets
Important! The installation of the eaves should be done below the waterproofing carpet. Then the resulting condensate will enter the catchment or blind area.
There are two ways to cover the roof with corrugated board with your own hands: cover the previous sheet with the next one, or put it under the bottom. You need to fix the profiled sheets to the crate with self-tapping screws with an EPDM gasket to protect against moisture. The number of screws is calculated based on the formula: 5-7 pcs. for 1 square meter of roof. To fasten the profiled sheets, the screws are screwed into the upper wave of the profile with a step of 0.5 cm.
Helpful advice! To avoid deformation of the gasket, try to tighten the screws carefully and without additional effort.
It is important to screw the screws into the corrugated board correctly
Profiled sheets can be fastened in a four-block or three-block way. In the first version, the installation sequence is as follows:
- First sheet of the first row.
- Second sheet of the second row.
- The second sheet of the first row.
- Second sheet of the second row.
In the second option, the sheets must be fastened according to the scheme:
- Two sheets of the first row.
- One sheet of the second.
Installation of additional elements. Snow holders
After installing the corrugated board, it is necessary to install those additional elements that were not attached during the roof: a ridge, ebb tides, corner strips, snow holders, etc.
Complementary elements for a roof made of corrugated sheets
Considering our climatic conditions with harsh and snowy winters, snow barriers are an important element of the roof. Due to the high heat capacity of the profiled sheet, the bottom layer of snow is flooded and there is a danger of its avalanche-like descent.
Installing snow guards with your own hands allows you to evenly distribute the load on the roof, ensuring safety and increasing thermal insulation due to the snow cover. Also, snow protectors protect the protective layer of the profiled sheet from damage by solid particles contained in the snow.
Snow holders will protect against snow from the roof in winter
Helpful advice! Considering the cost of snow holders, you can fix them not over the entire roof surface, but in the most important places: above the paths and entrances to the building.
Snow holders have different sizes and designs, the choice of which is determined by the average height of the snow cover of the area, as well as by the characteristics of the roof. It should be remembered that the installation of snow guards does not free the roof from the snow on a regular basis.
Based on the information received and the video materials presented, you can easily and quickly create beautiful roof own home yourself.
