The Duro-Last membrane is a proprietary thermoplastic formulation that provides exceptional flexibility, reflectivity, resistance to U.V. radiation, and flame retardance.
Duro-Last adds no “filler” material to increase the membrane thickness; our membrane’s top film thickness is equal to or greater than that of other single-ply products. It contains a weft-insertion scrim with a density of 18 x 14 threads-per-inch.
Duro-Last warranties provide unparalleled security for virtually all commercial roofing applications.

Each Duro-Last Designer Series system provides an aesthetic look plus the watertight performance and long-term durability of Duro-Last’s single-ply roofing system. We offer Shingle-Ply® and Rock-Ply® systems with each design printed onto the membrane. A special coating helps protect the finish from marring, fading, and dirt accumulation.
The Vinyl Rib system consists of the Duro-Last single-ply membrane and separate vinyl ribs. Membrane sections are adhered to the roof deck and overlapping edges are heat-welded together, forming a watertight, monolithic covering. Vinyl Ribs are then heat-welded to the installed membrane delivering an aethetic, architectural standing-seam look with the performance of Duro-Last's proven, thermoplastic, single-ply system.
