One of the most affordable and versatile materials used today in construction is a profiled sheet or corrugated flooring. It is widely used in the construction of outbuildings, fences, wall cladding and roofing work. Due to the ease and ease of installation, professional flooring can lay and amateur. Let’s try to figure out how to cover the roof with a professional sheet with your own hands. Video and photo examples of roofing work will help to understand this issue.
What is a profiled sheet and how they roof
Thanks to the development of advanced technologies, new materials appeared in the construction, with high performance and an affordable price. The professional flooring is a high-tech building material – galvanized corrugated metal sheets of various sizes with or without a polymer coating.
From the outside, the profiled sheet consists of the following layers:
- galvanized sheet – the basis of the professional sheet;
- anti-corrosion coating;
- polymer coating;
- protective mounting film.
On the inside, the sheet can also be protected with an anti-corrosion layer and a protective lacquer.
Due to the high protective characteristics and aesthetic qualities, the professional sheet is simply indispensable in the arrangement of the roof. Ease of use of this material is also that the wall covering, the installation of fences and the roof of the roof can be done by hand. Numerous specialized sites have video and photo instructions on how to roof the roof with professional sheets.
High strength, anti-corrosion properties and rigidity in combination with a variety of sizes and low weight ensured the popularity of sheeting in the construction of various types of premises.
The main advantages of using a professional sheet include the following:
- small weight;
- ease of self-assembly;
- availability of component materials;
- ease of transportation and storage;
- low price;
- wide range of sizes;
- high aesthetics of the coating.
The use of professional sheet accelerates the time and total construction costs with their own hands. A small number of joints ensures the reliability and tightness of the structure, and the low weight allows the professional sheet to be fixed even to beginners.
After entering the construction markets of profiled sheets, roofing with this steel material is performed much faster and easier. A large amount of information, photos and videos, how to cover the roof with a professional sheet with your own hands, allow you to learn how to fix the roof of corrugated board yourself.
Like many repairs, roofing with a professional sheet is best for two people. It is first necessary to clarify the dimensions of the area to be covered with corrugated flooring, to make sure that the ramps are rectangular in shape and to check their plane with a level. Then decide on the color, shape, thickness and brand of the professional sheet, as well as select the necessary tools and accessories.
A variety of types, forms and a wide range of the sizes of a professional leaf for a roof give the chance to find the necessary material for any roof.
The professional sheets are distinguished by the height of the corrugations, the presence of a capillary groove and a variety of colors of the polymer coating. The shape of corrugations corrugated is trapezoidal and sinusoidal, less often a sheet of rounded and rectangular shape.
The capillary groove is necessary to take moisture from the roof when docking professional sheets with an overlap, and the polymer coating provides a protective and aesthetic function. Due to the variety of colors, you can mount the roof of any color with your own hands, giving a special personality to the dwelling.
Important! All data on the professional sheet is reflected in its labeling. For roofing use profiled with marking letter H – the carrier, and the subsequent number of numbers means a number of characteristics.
For example, decking is marked H-60-0.7-840, which means:
- decking for roofing;
- height of the corrugations 60 mm;
- metal sheet thickness 0.7 mm;
- mounting width of sheet 840 mm.
The choice of professional sheet is made depending on the purpose of the premises under construction and the climatic conditions of the area. Unheated premises, sheds, hangars and other outbuildings can be covered with an inexpensive galvanized corrugated flooring without a polymer coating. Residential buildings, where the angle of inclination of the roof is more than 10 °, should be covered with professional sheets with a polymer coating, a large metal thickness and high corrugation.
Important! When choosing a professional sheet, pay attention to its appearance. The surface of the material should be smooth, without cracks and scratches, with an intact protective film.
An important parameter when choosing a profile sheet is the angle of the slope. The greater the angle of the slope, the greater the surface of the roof, the higher the windage, but the lower the snow load, since the snow easily rolls down from the sloping roof. To avoid deformations, the roof of a small slope should be covered with a thicker sheet.
Before you cover the roof with a sheet of steel with your own hands, you need to decide on the tool and purchase the appropriate materials. For self-installation of the roof of corrugated board you must have the following:
- cordless screwdriver;
- construction stapler;
- electric shears and hacksaw for metal;
- building level;
- roulette wheel;
- markers of different colors;
- gun with sealant;
- drill with a set of drills;
- self-tapping screws with sealing washer;
- skate for joining sheets;
- metal brush to remove chips;
- wind strip from rainwater;
- snow racks on the roof of the professional sheet.
The main stages of roofing with their own hands using professional sheets are:
- roof design;
- installation of crates;
- determining the size and number of professional sheet;
- definition of components and additional elements;
- installation of a professional sheet on a roof roof;
- installation of wind slats, skate and snow guard.
Before you cover the roof with a professional sheet, you need to decide on the project. This can be done with the help of specialized construction programs or to calculate independently. If you have to cover a complex roof with a lot of ramps at different angles of inclination, it is best to use ready-made programs or contact the architects. With a simple design, the question of how to cover the roof with a professional sheet without a special program is solved by ordinary mathematical calculations.
The basic formula for calculating the number of profiled sheets to cover a simple roof is as follows:
Where N is the number of professional sheets for laying the 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 size of the roofing sheet, it is necessary to keep in mind that the calculations take into account not common, 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.
The size of the horizontal overlap depends on the angle of the slope and is determined by a special table:
|Slope 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 chosen professional flooring and needs to be covered with overlapping waves.
Profiled sheeting plays an important role in determining the size of the overhang: the greater the height of the corrugations, the longer should be the overhang. With a short overhang, water may leak under the roof.
After determining the number of horizontal professional sheets, you need to calculate how many such rows are necessary to cover the roof. This value is calculated based on the length of the slope of the roof, the eaves overhang, the roofing sheet, the size of the overlaps, and also taking into account the additional elements.
Before you begin to fix the professional flooring with your own hands, it is advisable to view the appropriate training videos and photos. The roof of the roof with a professional sheet should be started after the installation of end boards, from the bottom row, with the expectation of the size of the overhangs. To the upper end board you subsequently need to attach the end plate of the profista (wind corner). Then use self-tapping screws to set the eaves bar.
Important! Installing the ledge should be made below waterproofing carpet. Then the resulting condensate will fall into the catchment or blind area.
You can cover the roof with a professional flooring with your own hands in two ways: cover the previous sheet with the next one, or put it under the bottom. Professional sheets should be fixed to the crate with self-tapping screws with EPDM gasket to protect against moisture. The number of screws is calculated on the basis of the formula: 5-7 pcs. on 1 sq.m of a roof. To fasten the profiled sheets, screws are screwed into the upper wave profile with a step of 0.5 cm.
Helpful advice! To avoid deformation of the gasket, try to tighten the screws gently and without additional effort.
Professional sheets can be fixed in four-block or three-block way. In the first embodiment, the sequence of installation is as follows:
- The first sheet of the first row.
- The second sheet of the second row.
- The second sheet of the first row.
- The second sheet of the second row.
In the second embodiment, the sheets need to be fixed according to the scheme:
- Two sheets of the first row.
- One sheet of the second.
After the installation of corrugated board, it is necessary to install those additional elements that were not fastened during the roofing: ridge, ebb, angles strips, snow holders, and so on.
Given our climatic conditions with harsh and snowy winters, snow protectors are an important element of the roof. Due to the high heat capacity of the proflist, the lower layer of snow is flooded and there is a danger of an avalanche of it.
Do-it-yourself installation of snow catchers allows you to evenly distribute the load on the roof, ensuring safety and increasing thermal insulation due to snow cover. Also, snegozaderzhateli protect the protective layer of professional sheet from damage by solid particles contained in the snow.
Helpful advice! Given the cost of snegozaderzhateley, you can mount them not over the entire surface of the roof, but in the most important places: above the walkways and entrances to the building.
Snegozaderzhateli have different sizes and design, the choice of which is determined by the average height of the snow cover area, as well as the features of the roof. It should be remembered that the installation of snow guards does not exempt from regularly releasing the roof from snow.
