Stevens Roofing Systems is a leading global provider of thermoplastic roofing membranes. For over a quarter century, beginning with the introduction of our Hypalon® roofing membrane, Stevens has been the specified choice of building owners, architects, specifiers and roofing contractors for both new construction and re-roofing applications. We invented reinforced thermoplastic polyolefin (TPO) and launched our industry changing Stevens EP™ membrane back in the early 1990's. 

Today we continue to manufacture and market some of the most technically advanced commercial roofing materials available on the market. Our EV® membrane, an Elvaloy® HP modified PVC – the first roofing membrane based on DuPont's High Performance Elvaloy® technology, sets a new standard in PVC roofing membrane performance. All of our membranes are manufactured in an ISO 9001:2000 facility and are integrated with the finest system components and high quality service to deliver a broad range of solutions for your roofing requirements.

Our philosophy at Stevens is simple:  develop versatile systems backed by knowledgeable service, and work hard to provide the right solution for the project, every time.  So when you install a Stevens roof, you’re getting more than just a membrane.  You’re getting everything you need to put the best roof on your building.
