Specifiers Prefer Duro-Last® Roofing Systems

Specify a Roofing System with Proven Performance

Architects, engineers and consultants across North America specify Duro-Last Roofing Systems. This is why:

An Integrated Approach

Our approach provides seamless integration between the architect, the contractor, and Duro-Last - the manufacturer. We take each roofing design that you create, and turn it into a complete system, manufactured to your specifications, including all components and details. We then deliver the entire roofing system to the job site for installation by an authorized Duro-Last contractor.

The Prefabrication Advantage

Through our custom prefabricated roofing systems – which can include both membrane and accessories – up to 85% of the seams can be completed in our factory-controlled environment. This eliminates most of the on-site fabrication that can lead to roof leaks. The results are a long-lasting, reliable roof.

In-House Support

Duro-Last offers a large team of knowledgable professionals, whether you need CAD drawings for a meeting, specifications for a unique project, or an answer to a technical question, we can provide the resources you need to get the job done.

Industry-Leading Warranties

Duro-Last warranties provide unparalleled protection for commercial roofing applications. We were the first manufacturer to offer a warranty that expressly covers consequential damages.

Durability = True Performance

The unique formulation of Duro-Last Roofing Systems delivers long-term value and peace of mind. Two differentiators Duro-Last offers are a high-quality reinforcement scrim and thickness above scrim.

  • Knitted in-house, our anti-wicking polyester weft-insertion scrim has a 14 x 18 or 14 x 9 threads-per-inch density – among the highest in the industry. Duro-Last's scrim uses a third tie yarn to prevent runs and doesn't allow tears to spread. The scrim is the backbone of all Duro-Last’s membranes, giving them their strength and puncture resistance.

  • The thickness above scrim of each Duro-Last Roofing System – also known as the “performance layer” – exceeds the ASTM minimum standard. Compared to competitive products, Duro-Last's membranes have the thickest film over scrim. Duro-Last Roofing Systems provide protection where buildings need it most: the exposed surface of the membrane.
