Roofing from the corrugated board with your own hands is not difficult.
They can cover the roof, which has a large area, and the price of the material will not be too high.
Excellent characteristics of corrugated board are a good choice in its favor to cover the roof.
When constructing a house, the roof can be a single-pitched roof and a two-track roof.
A roof with two skates is preferable for the construction of a dacha, a residential house.
Single-pitched roof is most often used in the construction of utility buildings: baths, a garage, a store room, a barn. The single-deck roof construction is quite simple, reliable, economical.
Its installation is carried out quickly, because such structures do not differ in large dimensions.
The slope angle of the saddle roof must be calculated individually, depending on the characteristics of the structure, climatic conditions.
Sometimes a flat roof forms during the construction of a residential house. The concept of "flat" - not exactly accurate.
Be sure to observe the minimum slope of the roof from the corrugated board, which will drain rain and snow. The angle of inclination of such a roofing pie should be 2-4 degrees.
A flat roof can save money, as it does not need to create a truss system for its arrangement.

When building a house, it is important not only to pay attention to the foundation and walls.
The installation of the roof from the corrugated board is the stage on which the operational parameters and the attractiveness of the structure depend.
The technology of roofing with profiled sheeting is simple, so even a beginner builder can handle it.

Criteria for choosing the corrugated board
The qualitative structure of the roof from the corrugated board depends on the ability to select the material correctly.
Before buying it, it is worth to thoroughly inspect the corrugated board, its characteristics must comply with the standards:
- the surface of the sheet should not have any dents, defects;
- edges of the corrugated board must not have burrs, chips;
- sheet should be evenly colored;
- when checking the sheet for bending the paint should not break off or crack, when the
- is unbent, the quality corrugated board immediately takes on the original form.
It is worth taking into account the climatic conditions of the area where the house will be built.
If the area is characterized by the precipitation of a large amount of precipitation in the winter, the thickness of the corrugated board must be large, the angle of rigidity is high.
It is also worth considering that the angle of the roof should not be less than 15 degrees.
If there is not enough precipitation in the area of precipitation, then you can choose a material with a lower index of stiffness.
Before you bring the purchased corrugated board, accessories to the construction site, it is worthwhile to prepare the place where they will be located.
Sheets should not be deformed, otherwise it will not be possible to achieve reliable junctions. Also, in advance, you need to make devices that will properly and accurately lift the corrugated board on the frame.
Installation of hydro and steam insulation
The technology of laying corrugated board involves the arrangement of layers that prevent penetration of moisture and steam - this is the so-called roofing pie.
As a waterproofing roofing cake can contain roofing felt, roofing felt, pergamine. In addition, the design can have more modern materials - glass-glass, hydro-glass, bicrost.
Steam insulation involves the use of propylene or membrane films.
Arrangement of roofing with polyethylene is not recommended. The steam will condense. As a result, the walls in the room will be exposed to mold, which will lead to their destruction.
Waterproofing, vapor barrier is fastened to the rafters, for this use a construction stapler. Roofing made from corrugated board can only be provided with reliable joints.
Material must be started from the bottom of the roof. Thus, sealing will be performed.
During the operation of the building, moisture will not penetrate into the under-roof space, since the hydro- and vapor barrier will prevent it.
After the hydro-and vapor barrier is laid in the roof cake, it is possible to make a crate.
It is recommended to attach wooden slats to the insulation material, and already lay the crate on them.
This will ensure ventilation, moisture will not form between the roof and vapor barrier.
Before laying, the components of the billet should be treated with special compounds that prevent fungus infection and impart fireproof properties.
The thickness of the corrugated board affects the nature of the crate. When using a thin profiled sheet, the lath must be continuous.
Video:
Sheets that have a large thickness are laid on a thin crate. In this case, the angle of inclination of the roof, the climate, the size of the profiled sheet influence the frequency of the laying of the beams.
Video lesson will help to properly install the waterproofing and crate.
All construction activities must be carried out with the conditions that the technological map contains. Only in this case the roofing cake will be of high quality.
Fastening of corrugated board
It is recommended to fasten profiled sheets to the crate with the help of self-tapping screws.
In the sale of components are presented in different colors, so they can be selected in the tone of the corrugated board.
For one meter of corrugated board it is recommended to use 5-7 screws. Thus, the sheets will be securely fastened to the crate.
The angle of the roof slope affects the way of laying the corrugated board:
- the angle of inclination is less than 12 degrees - it is recommended to use silicone sealants when laying;
- angle of inclination 12-15 degrees - profiled sheets must be overlapped. It should be about 200 mm;
- angle of inclination 15-30 degrees - overlap can be made 150 mm, but 200 mm is allowed;
- the angle of inclination is more than 30 degrees - it is necessary to observe the overlap of 100-150 mm.
The device of a roof from a professional flooring is necessary for beginning from below - sheets fasten to wooden bridges overlap. When building a gable roof, work should be done from the right end.
If the roof has a tent type, the sheets are stacked on two sides, the work starts from the highest point of the ramp.
First of all, the curtain rod is installed. It is fixed with screws. Between the corrugated board and the curtain rod is to lay the sealant.
In this case, the bar itself should protrude beyond the overhang by 4 cm. The lower edge of the profiled sheet has a gutter groove. It must necessarily be located from the bottom.
Profiled sheeting must be leveled, paying attention to the overhang, joints are not taken into account. How the roof is made of corrugated board, the video instruction provided will show.
The correctness of the laying of the corrugated board on the roofing cake and the characteristics of the future roof depend on the precise implementation of the following rules:
- A metal sheet is attached to the ridge and the overhang is not strong. It is lowered for overhang by 4 cm. After that, the second sheet should be laid, the edge of which is aligned with the first sheet. The second sheet is also attached temporarily. On the crest of the wave, the sheets need to be connected by fastening material from the overhang to the ridge - a step of 50 cm.
- After several sheets have been installed in this way, the roof overhangs them and then firmly fixed. Mounting is done at the bottom of the wave. The video will give clarity to the fixing of the corrugated board;
- Further laying of the material is carried out overlapping, sheets are fixed on the bottom of the wave.
During the fastening of the ridge, it is necessary to make ventilation gaps correctly. The profiled sheet should be from the ridge at a distance of 5 cm.
The skate itself must be fixed with self-tapping screws, and closed with special plugs on the sides.
After laying profiled sheets on the gables of the roof, you need to put the windshields of metal.
When forming a roof, it is worth paying more time and attention to how the roof assemblies are assembled from the corrugated board.
Nodes are the places of abutment of sheets to the wall of the building or the point where the corrugated board joins one another.

If all work is done correctly, in the future, the roof structure will not be affected by adverse effects.
At the junction of sheet materials, where the horizontal part of the roof goes to the vertical, you need to install the bar. Its function is to prevent dust and moisture from getting inside the box.
Erection of the cornice
A curtain overhang protects the walls from water draining from the roof surface during rain or after snow melting. On its slope, water moves into a special chute, while the wall remains dry.
Overhang should be 55-70 cm long. If the roof skeleton has very steep ramps, the overhang can be of shorter length. But it's worth it to be ready, that when you slant the rain, moisture will fall on the wall.
The characteristics of the curtain rod should be such that they protect the roof cake and the whole roof frame from the effects of moisture.
Video:
When forming a waterproofing membrane is important to lay on top of the abutments of the cornice. Otherwise, the overhang will not perform its functions, which will lead to the destruction of the walls, the frame will be damaged.
If the overhang is supposed to be used as an additional cover over the building's balcony, then at the bottom of the eaves it is covered with profile sheets, the same as the carcass was covered.
