Whether you’re a distributor, contractor, architect, specifier or owner, our goal is to provide the products and services you need to be successful. A working partnership with GenFlex begins with a sales team of dedicated professionals, while our technical representatives, technical advisors and customer service representatives are available every step of the way. Our knowledgeable team can work with you to provide insight on the building and the project’s parameters.

You’ll find that our flexible, hands-on approach makes us easy to do business with. And our quality roofing systems, backed by Firestone, the industry leader, make us a company you can count on.

Big ideas have long defined who we are and what we do. In fact, our roots date back to 1915 with General Tire, one of the pioneers of polymers and reinforced plastics. Today, GenFlex continues to focus on the future, researching and developing better solutions to combat the elements, and new opportunities to meet the needs of the marketplace. Want proof? Just take a look at some of the significant industry firsts we’re known for:

1981: GenFlex becomes one of the original suppliers of EPDM systems. The company is also the first to market EPDM seam tape.
1996: GenFlex develops the first 12-foot-wide TPO sheet to meet industry code requirements, and it is still the widest sheet available.
2003: GenFlex launches the revolutionary Peel & Stick(TM) system, one of the most significant advancements in roofing in the past decade.
2010: GenFlex introduces FlexWhite EPDM, a white-on-black EPDM membrane that combines the benefits of a highly reflective white-surfaced membrane with the proven application techniques of a flexible EPDM roofing system.

Today, our roofing systems and components provide a high-quality product, easier installations and a complete array of warranties to meet your needs, as they evolve.
