About Polyvinyl Chloride (PVC) Roofing

Polyvinyl Chloride (PVC) single ply membranes have been around for almost 50 years. Originally installed in Europe, they quickly gained popularity in the United States. PVC membranes are composed of three layers — a strong polyester reinforced fabric sandwiched between two layers of PVC polymer plies. PVC is available in thicknesses ranging from 45-80 mils.

PVC can be installed in three ways; loose laid, fully adhered, and mechanically attached. The loose laid installation requires ballast such as river rock or pavers to hold the membrane in place. Fully adhered is a method where the membrane is completely glued in place using commercial grade adhesives rolled on both the backside of the membrane and the substrate. Mechanical attachment utilizes screws and plates to hold the membrane in place. The fully adhered method is recommended because it prevents water migration under the membrane in case of a membrane puncture.
