During roof’s installation it is very important pay particular care about the succession of coats to ensure effectiveness with their functions. Basic elements are:
– damp-proof membrane and vapor sealing pellicle;
– warmth-keeping lagging;
– protection against wind;
– roof-boarding material;
– ventilation arrangement;
– other components.
Roof installation implies coming of this type of “pie”, which in the final stage is roofed with cladding or thatching, and, if necessary, is painted.
