Single Ply membranes generally consist of either EPDM, TPO or PVC.  These sheet membranes come in widths ranging from 6 to 12 feet and are heat welded together to make a high quality watertight barrier. The membranes come in standard colors of white, gray and tan with manufacture warranties ranging from 10, 15, 20 and even up to 30 years that cover materials and workmanship.  EPDM, TPO and PVC FleeceBack membranes can even receive a warranty against hail damage from 2” coverage all the way up to 4” hail coverage depending on the membrane thickness and roof conditions.  With all the options and excellent warranty coverage, its no wonder why single ply membrane roof systems have taken over the commercial market.  Coontz Roofing is proud to offer quality single ply membranes and is certified with Carlisle, Firestone, Sarnafil, and Fibertite.
