Membrane Products
Designer Series Membrane Products
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.
Membrane Products
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.

Through Duro-Last’s prefabrication process, the entire roofing system, including all components and accessories, is designed to fit building specifications exactly, manufactured in one of our five plants and then delivered to the jobsite for installation. This process eliminates up to 85% of on-site rooftop membrane seaming, reducing errors during installation. Prefabrication also offers:
• Less labor and easier installation in all weather
conditions allow for Time Off the Roof™
• Reduced waste
• A solution for aesthetic design challenges
