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^{[citation needed]}. The British Board of Agrément states that certain vinyl roof membranes "should have a life in excess of 40 years."^{[citation needed]} Vinyl roofs are also the only type of commercial roofing product that has an active recycling program in place.^{[citation needed]}
