Roof covering installation and assembly

Roof structure is often called “roofing pie” and not without reason – indeed, any rooftop consists of several elements, which, sort of stratifying on each other, create strong safeguard for housing. Each of coating construction’s layers performs its own designated role, whether that be moisture-proofing, noise insulation, or defense against heat loss. During roof’s installation it is important to pay particular attention to the sequence of coats in order to ensure effectiveness of 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 creation of such a “pie”, which at the final stage is covered with cladding or thatching, and, if necessary, is painted.

These stuffs are designed specifically for terraced-roof option, customized in light of its profile, that gives 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. Extruded heat retainers, mineral wool rigid insulants and expanded plastics are applied for flat-deck roofs’ winterization. Installation technologies and insulation’s choice is determined by roofing type and loads intensity on it.
