The roof coating with bitumen tiles is conditionally divided into the preparatory stage and the process of laying elements. First, a wooden crate is prepared, which is the basis for laying elements. It provides a ventilation system that looks in the form of holes under the skate of the roof, as well as natural gaps around the perimeter of the base of the ramp. After preparing the crate on top, a special covering carpet is creeping on it, which serves as waterproofing material. After that, a layer of insulation over the entire surface is attached to the crate.
