It can get ugly out there. That’s why you need a durable TPO roofing system that can keep its cool under extreme conditions, and keep you looking good in the process. GenFlex EZ TPO single-ply roofing systems fit the bill. Our TPO systems, including the revolutionary GenFlex EZ TPO Peel & Stick™ HW, offer the durability it takes to withstand the most punishing elements. Plus, they provide outstanding heat-reflectivity and energy efficiency for high performance that’s strikingly affordable.

GenFlex EZ TPO membrane, a high quality thermoplastic polyolefin, offers the “best of both worlds”…the proven flexibility and weathering resistance of rubber and the performance of hot-air welded thermoplastic seams. Heat-welded thermoplastic roofing membranes are the fastest growing segment of the low-slope roofing market and GenFlex EZ TPO is an excellent system choice. Here’s what you can expect from a GenFlex EZ TPO System:

  • Smart Firsts: GenFlex developed the first 12-foot wide TPO sheet meeting industry code requirements. A wider sheet means fewer seams to weld and fewer panels to install, and that can add up to big savings. Compared to a 10-foot system, the wide sheet application requires 16% fewer seams—33% fewer than an 8-foot system, and 50% fewer than a 6-foot system.

  • More Options: GenFlex EZ TPO systems offer the widest selection in both product and system types.  From dual weld seams to Peel & Stick systems, GenFlex has the TPO products you need for mechanically anchored to fully adhered systems with warranties up to 20 years depending on the system design.

  • Better Ideas: Introduced in 2003, the GenFlex EZ TPO Peel & Stick HW membrane system is truly a revolutionary new era in roofing. Peel & Stick TPO membranes and accessories have pre-applied adhesive and tape, making installation faster, easier, safer and smarter. Now available in a 10-foot roll as well.
