Duro-Last PVC Membrane
Over three decades of proven PVC roof system performance.
The Duro-Last vinyl roof membrane is a proprietary thermoplastic formulation consisting of PVC resins, plasticizers, stabilizers, biocides, flame retardants and U.V. absorbents.
A weft-insertion knitted scrim that is laminated between two layers of PVC film gives the membrane its strength and durability. The Duro-Last single-ply membrane is available in white, gray, dark gray, tan, or terra cotta.

The Duro-Last Advantage: The leading feature of Duro-Last is its exclusive thermoplastic formulation, specially designed to offer remarkable flexibility and reflectivity. The Duro-Last membrane is available in thickness options of 40, 50, and 60 mil, and can be tailored to precise building specifications through custom fabrication. By opting for the custom-fabricated Duro-Last Roofing System, as much as 85% of seams can be efficiently completed in our controlled factory environment, resulting in significant reductions in rooftop labor and the risk of potential leaks. Moreover, the Duro-Last membrane is fortified with an anti-wicking scrim, ensuring exceptional strength and resistance against punctures.
Our flexible roof membrane is easily prefabricated into deck sheets up to 2,500 square feet in size, as well as a custom-made parapet, stack, and curb flashings that eliminate most labor from critical roof areas – transitions and changes of plane. Prefabrication provides architects, specifiers, consultants, contractors, and building owners peace of mind regarding the watertight security of the roof installation.
Duro-Last has met or exceeded all major fire and wind code requirements, and regional approvals as necessary throughout the country. These certifications reinforce Duro-Last’s leadership in providing the consistent, watertight integrity that building owners expect.
Duro-Last is proud to be a charter partner of the ENERGY STAR® Roof Products Program. The ENERGY STAR label indicates to building owners and managers that the Duro-Last white vinyl roof membrane can save them money on cooling costs due to its high reflectivity (which reflects 88% of the sun’s energy).
Duro-Last is also a charter member of the Cool Roof Rating Council (CRRC) and a member of the United States Green Building Council (USGBC). Duro-Last participates in all major technical committees in the roofing industry, plus the American Society of Testing Materials (ASTM).
