GenFlex TPO membrane was introduced in 1996 and is manufactured at our state-of-the-art extrusion technology facility in Muscle Shoals, Alabama, where we have produced the industry’s first 12-foot wide sheet meeting industry code requirements
The 12-foot wide sheet offers significant benefits including fewer seams to weld and fewer panels to install. With fewer seams and fewer panels for most applications, there is a significant cost advantage to a 12-foot fully adhered system. 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
GenFlex 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 TPO is an excellent system choice.
GenFlex TPO roofing systems are designed for durability and to withstand extreme environmental exposure. GenFlex 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
Introduced in 2003, the GenFlex Peel & Stick™ TPO 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.

In today’s fast-paced marketplace, manufacturers are rushing to be a part of the growing demand for TPO roofing systems. Many of these manufacturers have little-to-no TPO or single-ply roofing experience. The Smarter Choice is to select a manufacturer who has been making and supplying TPO for more than 15 years: Versico.
Thermoplastic polyolefin (TPO) is the fastest-growing segment in the commercial roofing industry. To take advantage of this recent popularity, a growing number of companies have begun offering TPO single-ply membranes. Unfortunately, not all TPO is created equally. Your building deserves a TPO roofing system provided by the manufacturer that has been at the forefront of TPO research, development and technology since the inception of TPO as a roofing membrane.

PVC roofing systems result in a cleaner, quicker, more economical installation able to withstand heat, wind, rain, varying temperatures and many contaminants. The heat-weldable seams provide a unified, watertight seal as strong as the membrane itself. Systems can be installed fully adhered or mechanically fastened.
