A vinyl roof membrane is a polyvinyl chloride (PVC) roofing membrane used in commercial construction. Vinyl roofing membranes have been around for over 40 years in the U.S. and longer in Europe. The British Board of Agrément states that certain vinyl roof membranes "should have a life in excess of 30 years." Vinyl roofs are also the only type of commercial roofing product that has an active recycling program in place.
