Roofers “Roofing in NYC” is a free measurement of the roof – the calculation of the cost of work and material for installing a shelter from a profiled sheet.

Be sure to take into account the angle of inclination of each roof slope. If the indicator of this parameter does not exceed 14 degrees, then the sheets are laid by the overlap method with a grip of about 20 cm. If the roof slope is inclined at an angle of 15-30 degrees, then the grip is made 15 cm, and if more than 30 degrees, then 10 cm.

The type of corrugated board used determines the method of mounting the lathing. For C20 grade material, a solid crate is made, for C35 – with a step of 30-50 cm, and for C44 – with a measure of 50 cm. If you just plan to change the old coating to a new one, the crate does not need to be altered.

Since the profiled sheets are relatively lightweight, they do not exert significant loads on the roof. This eliminates the need to build a robust and, accordingly, expensive rafter system. To fix the corrugated board on the roof, roofing screws are used. The end of such a fastener has a kind of drill, and a neoprene lining is located under its head. The color of the roofing screws can be different, which allows you to choose fasteners for any color of the corrugated board.

Self-tapping screws are twisted only through the descent of the sheet wave. Self-tapping screws 8 cm long are used to fix the ridge of the roof and 4–5 cm for all other sections of the top. To create cuts on the corrugated board, for example, for passages or grooves, metal shears or a circular saw are used. The resulting metal shavings are removed with a soft brush. The grinder cannot be used for cutting corrugated boards.

If scratches appear on any sheet, they are immediately painted over with a paint that matches the color. The edges of the sheets from the side of the roof arch are also covered with paint. It is not recommended to use aerosol paints and varnishes for this. Gloves and protective clothing should be used when installing the corrugated board. If the sheets are cut with a circular saw, then you must also wear special glasses.
