The drainage system needs almost every roof.

The drainage system needs almost every roof. The drainage system protects the base, as well as walls from water, but also protects the foundation from excess humidity, not allowing to collapse. With the help of a drain from the roof, water is collected in a gutter and excreted through pipes, in this case the building will not be destroyed. Drains are supplied with all the necessary fasteners and sashes. The shape of the pipes and gutters is rectangular or round.
