Various materials are used for replacing flat roofs including built-up roofing (BUR), modified bitumen, single ply, and sprayed polyurethane foam (SPF). Single ply roofing is preferred on commercial flat roofs because the material is lightweight and features a combined layer of membrane and weathering surface.
The most common single-ply roof material is EPDM, also called synthetic rubber. Also used in single ply applications are polyvinyl chloride (PVC) and thermoplastic polyolefin (TPO). PVC roofs are considered more durable and TPO installations are more economical. Modified bitumen is used on single ply roofs, as well.
