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 membrane is available in white, tan or gray.
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 has been approved by Factory Mutual as a 1-60,1-75, 1-90, 1-95, 1-105, 1-135, 1-150, 1-165, 1-195, 1-210, 1-270, 1-435, and 1-495 roofing system. Duro-Last is also listed by Underwriters Laboratories as a Class A, B, & C approved material. Evaluation services ICBO and NES have merged to form ICC-ES, which has evaluated Duro-Last for the International Building Code (IBC). The Duro-Last roofing system has been approved by the IBC and by code agency MIAMI-DADE for use in their respective jurisdictions.
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 (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).
In the commercial roofing industry, reflectivity has been the dominant discussion point for several years, and the Duro-Last® Cool Zone® roofing system has set the standard for single-ply roof reflectivity and the resulting energy savings. Now the term “sustainability” is receiving a lot of attention, and once again, Duro-Last is setting the bar.
But what does sustainability really mean for building owners, facility managers, contractors, architects, and other specifiers? It means that the design, construction, maintenance, life-cycle impact, adaptive re-use, destruction, and recycling of roofing components must help meet the long-term environmental standards demanded by today’s high-performance buildings.
To be considered “sustainable,” a roofing system must meet the Five E’s of high-performance roofing: Energy, Environment, Endurance, Economics, and Engineering. In each of these areas, the Duro-Last Cool Zone roofing system leads the commercial roofing industry. Click on the icons above to learn more about the Five E’s and how the Duro-Last Cool Zone roofing system delivers on the multiple demands of high-performance roofing.

Benefits of the Shingle-Ply roofing system:
The Duro-Last Shingle-Ply System is ideal for commercial
applications where building appearance is important,
but conventional shingles are not practical because the
roof’s slope may not provide good water runoff or the
roof has other limitations. The Shingle-Ply membrane
provides a shingle look and the watertight performance
and long-term durability of a thermoplastic, single-ply
roofing system.
Our Shingle-Ply product is made from the same durable
membrane as the Duro-Last roofing system, a proven
performer since 1978. The shingle design is printed
onto the membrane, then a special polymer coating
is applied to help protect the finish from marring,
fading, and dirt accumulation.
Shingle-Ply rolls are delivered to the job site ready to
be unrolled, positioned, and installed by an authorized
Duro-Last contractor. Each piece is aligned with the
installed adjacent piece and mechanically attached
to the roof deck. Overlapping edges are heat-welded
together, forming a watertight, monolithic covering.
Flashings for penetrations and other transition areas are
precision-fabricated in a Duro-Last facility; there is no
on-site assembly of these components. The Duro-Last
Shingle-Ply system is complete, with all fasteners,
flashings, edge details, and other materials delivered
to the job site.*
