(TPO) Thermoplastic polyolefin membranes are single-ply roof membranes constructed from ethylene propylene rubber.  TPO is highly resistant to tears, impacts, and punctures with good flexibility to allow for building movement. TPO membranes are available in white, light gray, and black with thicknesses of either 45 mils , 60 mils or 80 mils (.080”).

Properly installed TPO roof systems have service lives ranging from 15 to 25 years, depending on the type of installation. Full removal of the existing roof, the amount of slope the roof has, weather conditions, as well as several other criteria contribute to the longevity of a roof’s service life.

Adhesion and Fastening of TPO

TPO roofing membrane can be installed using mechanical fasteners and plates or using bonding adhesives in a fully adhered application. When mechanically fastened application is desired, fasteners are placed along the edge of the sheet and fastened through the membrane and into the roof decking, providing a quick installation. Whether it’s Carlisle, Firestone or any other quality product our customer demands, we supply and install it as per the specifications and manufacturers guidelines, ensuring our clients get the warranty backing on the work provided.

Mechanical Seam Welding

One of the primary benefits of TPO membrane is the ability to weld the sheets together with a hot air welder. Automatic seam welders as seen above left, provide solid and consistent welds. The welding process results in a bond that is actually stronger than the sheet itself.
