Roof made of corrugated sheeting Source

[zihadhosenjm40]

At the design stage of any building, be it a private house or an industrial building, a correctly selected angle of inclination of the roof slopes made of profiled sheet (corrugated sheet) will allow to increase wind resistance as much as possible, achieve rapid removal of snow, water, and also find a compromise between the amount of materials expended and the durability of the corrugated sheet. In this article, you will learn what is the minimum slope of a roof made of corrugated sheet that can be installed, the features when installing the roof at different angles and calculating the permissible angle of the planned roof.

Reason for the need for a minimum slope
Any non-flexible roof has a minimum angle to bangladesh mobile database horizontal surface of 10°. Using corrugated sheeting as an example, this is understandable due to the possibility of rainwater getting between the roof joints and a large amount of snow stagnating on the roof surface. There are no strict restrictions on the maximum angle, but roofs with steep slopes, where the angle of inclination is more than 60°, are less wind-resistant.

Concepts of angle and slope, minimum angle according to SNiP II-26-76*
The angle, measured in degrees, shows the deviation of the slope from the horizontal surface, and the slope, measured in percent, is the ratio of two legs of a right triangle, vertical to horizontal, formed by one slope and the base.

Based on the building codes and regulations of the Russian Federation for roofing SNiP II-26-76, the minimum roof pitch angle made of corrugated sheets installed on the roof of residential buildings is at least 10°, or a slope of at least 17.6%.
