During roof’s installation you will need to pay particular care about the succession of coats in order 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 advance of this kind of “pie”, which on the final stage is included with cladding or thatching, and, if needed, is painted.

These stuffs are created specifically for terraced-roof option, customized in relation to its profile, that provides them maximum protection against weathering, ultraviolet exposure, etc. Assembling rolled materials is accomplished by welding sheets of roll composition roofing using hot air. Various mastics allow achieving waterproof membrane’s perfect impermeability.
Assembly of membranous rooftops is executed by attaching the fabric to roofing’s screed; membrane sheets are fastened between each other by hot-air welding method.
