Learn about the Duro-Last Roofing System

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, gray, or dark 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.

We use Duro-Last Products for the
"World's Best Roof"


The Duro-Last Difference

Factories, schools, churches, government offices, and businesses of all types have chosen Duro-Last because our roofing system is:

Duro-Last is The "World's Best Roof"®

Duro-Last's custom-prefabricated, reinforced, PVC roofing system is ideal for any flat or low-sloped application. Extremely durable and easily installed by authorized contractors without disruption to daily operations, the Duro-Last single-ply roofing system is also leak-proof, resistant to chemicals, fire and high winds, and virtually maintenance-free. Over a billion square feet of the Duro-Last PVC roofing system membrane have been installed on all types of commercial, industrial, and institutional buildings throughout North America.

Prefabrication of Duro-Last's PVC roof membrane not only reduces the material waste associated with the installation of most rolled systems, it also eliminates 80-85% of the typical on-site, labor-intensive seaming required for other single-ply roofing systems. The Duro-Last roofing system also comes complete with all accessories included.

Prefabricated

Every Duro-Last single-ply roof is measured and manufactured to exact size, accommodating every rooftop penetration. Prefabricating the vinyl roof membrane in our controlled factory environment eliminates up to 85% of seaming that is done on-site during rooftop installation, and improves the long-term performance of the roofing system. This precise attention to detail ensures an excellent fit and delivers worry-free, leak-proof protection. Duro-Last can even assist your architect, facilities or maintenance personnel in developing specifications for your roofing project.

Durable

The Duro-Last roofing system, made from a PVC membrane, is resistant to fire, chemicals, grease, high winds, and punctures, and easily accommodates wide temperature extremes. Duro-Last's custom flashing components - made from the same vinyl roof membrane as our deck material - resist ponding water and help solve roof problems before they can occur. Plus with Duro-Last's available Roof-Trak® Protective Walkway System, heavy equipment and maintenance traffic are easily managed.

Installed With No Disruptions

Building occupants will hardly know a new roof is being applied, because installation is quiet and safe. Our PVC roof membrane is mechanically-attached to the deck; edges and vinyl roof components are heat-welded together to complete the watertight, monolithic roofing system installation. There are no loud machines, no hazardous materials, no noxious fumes, no hot tar, and no mess. Because it's made from lightweight vinyl, a new Duro-Last roofing system can often be installed over an existing roof without an expensive tear-off, virtually eliminating dust or falling debris that could interfere with building activities or damage sensitive equipment.

Energy-Efficient

PVC roofing systems make an important contribution to sustainable buildings, and Duro-Last is proud to be a charter partner in the EPA's ENERGY STAR® Roof Products Program. Duro-Last is also a charter member of the Cool Roof Rating Council and a member of the US Green Building Council.Our Cool Zone® roof system has high reflectivity and emissivity values - throughout its life span on the roof - that reduce the amount of heat transferred into a building. Cool Zone roofs are saving significant energy and money for building owners all over North America and increasing comfort level and productivity for building occupants.

From lowering a building's energy consumption to helping facilities obtain LEED® credits to reducing the urban heat island effect, the Duro-Last Cool Zone roofing system is a leading sustainable building product.
