What is the eagerness

Okap is the edge of the roof from which water dripping drips during rainfall. Okap has to work properly. The drainage of the roof can be solved by a roof gutter, an under roof or a mezzanine gutter.  The roof gutter is the safest, the fallen snow protects it. Gutter pipes are made of galvanized, titanium or copper sheet. Another option is stainless steel sheets, coated sheets and also plastic eaves, which are suitable for small buildings, such as pergolas .  Okap must be sprawled so that there is no water in it.
