PVC roofing is a modern long lasting roof system. PVC membrane was originally used as pool liners before later in the 60’s used in roofing. Due to i’ts long life cycle, sun reflection (cool roof), its chemical inter nature, burn resistance, and recycle-ability, it is considered one of the most economical, practical, and environmentally friendly roof systems. It is normally mechanically attached via screws or full adhered using low VOC glues. The seams are then hot air welded together to form a strong monolithic roof system.
