Examples of flat roof systems that are a single-ply system include: TPO (Thermoplastic Polyolefin), EPDM (Ethylene Propylene Diene Monomer) and PVC (Polyvinyl Chloride). These are the most popular products on the market today. There are several others like CSPE (Cholorsulfonated Polyethylene), PIP (Polyisobutylene) and KEE (Ketone Ethylene Ester); however, they are becoming less and less available as alternative products are being marketed.
Single-ply systems have their problems. Product manufacturing firms have made many changes to the chemical processes that go into these products. These systems have been challenged with shrinking from intense heat effects as well as system failure due to standing or ponding water issues. When these roof systems age to a certain point, the mesh or (scrim) will expose itself and trap latent moisture. At this point, the system is "past its useful life" and the owner bears the responsibility of repairing and or replacing the entire system before a catastrophic failure occurs.
Commercial Coating Pros specializes in restoring and refurbishing single-ply roofing systems, using state-of-the-art materials from leading manufacturers, at about half the cost of replacing them.
