Do I need flashing? Which flashing to choose?

A flashing is an essential element allowing correct installation of a roof windowin the roof slope. The precisely designed elements of the flashing enable tight and durable integration of the window with roofing. It is very important as the main task of the flashing is to drain water and snow away from the window and protect it against the wind. The flashings are manufactured from aluminium sheet, coated with polyester lacquer. The basic color is Grey – brown (RAL 7022), thanks to which windows fit  to standard colors of roofing materials. Flashings are used for connecting the windows with roofing and it is the roofing which decides about their selection.
