Stevens Roofing Systems is now Dow Roofing Systems.

Dow Roofing Systems is the leading global manufacturer of thermoplastic roofing membranes and the key component for commercial roofing in Dow’s global building solutions portfolio.

Innovation Leadership
For over a quarter century, beginning with the introduction of our Hypalon^® roofing membrane, Stevens roofing technology has been the specified choice of building owners, architects and roofing contractors for both new construction and re-roofing applications. We invented reinforced TPO (thermoplastic polyolefin) membranes and launched our industry-changing EP™ membrane in the early 90s.

Manufacturing Leadership
Today we continue to manufacture and market the most  technically-advanced commercial roofing materials. Our products are the only membranes manufactured in an ISO 9001 certified facility. And, our comprehensive No-Compromise(SM) Roofing Challenge combines an integrated and exclusive set of solutions in design, technology, quality, energy-efficiency and performance.
