After working as a lumberjack, carpenter, tool and die maker and soldier, among other jobs, John R. Burt got into the swimming pool business. After a liner he had purchased failed, he recognized the importance of vertical integration to control quality and founded
Tri-City Vinyl to manufacture his own pool liners.

One day it occurred to him: If his product could keep water in, it could keep water out. In 1978, that insight became the Duro-Last Roofing System.

The majority of roofing system failures then (and still today) are not due to the product itself, but to workmanship on-site.

To solve this problem, Duro-Last developed custom prefabrication methods and specialized equipment that allows us to complete nearly 100% of the difficult roof details and up to 85% of field seams under ideal factory-controlled conditions. The result is lower on-site labor costs and better installation quality. 

Learn more about our prefabrication benefits. 

Duro-Last is now the world's largest manufacturer of custom-fabricated roofing systems. Duro-Last Roofing Systems, our contractor installation team, customer service and best-in-class warranties all set the quality standards for the roofing industry.

Duro-Last Introduces Duro-TECH™ and Duro-TECH Fleece TPO

Duro-Last is proud to announce the expansion of its high-quality commercial roofing solutions with the launch of Duro-TECH and Duro-TECH Fleece TPO membrane product lines. This exciting addition marks Duro-Last’s entry into the TPO market, complementing its premium PVC product line with new cost-effective solutions that maintain the company’s high standards for quality, durability and ease of installation.

Both Duro-TECH and Duro-TECH Fleece membranes feature Duro-Last’s exclusive anti-wicking, weft-inserted scrim with a density of 9 by 9 threads per inch — an industry first for TPO membranes — eliminating the need for seam sealant during installation. This feature enhances installation efficiency, saving contractors time and reducing material costs while delivering watertight performance and durability. Additionally, each Duro-TECH membrane offers the most robust top film thickness in the industry — creating a resilient performance layer that stands up to the elements.

Duro-Last^® Sustainable Commercial Roofs

Sustainability has been a part of the Duro-Last culture for more than 20 years. Our founder, John R Burt, came up with the idea of reimagining old PVC roofs and manufacturing excess into resilient flooring, walkway pads and concrete expansion joints. To date, we have recycled more than 100 million pounds of PVC material through our sustainable manufacturing operations and Recycle Your Roof program.

We have continued our leadership in sustainability as the first manufacturer to publish a product-specific Environmental Product Declaration (EPD) for single-ply PVC roofing membranes.

Manufactured with the same formulation as the industry-leading Duro-Last^® membrane, Duro-Last X is an excellent choice for contractors seeking the convenience of roll goods coupled with the customization of custom-cut lengths. Designed to reduce scrap and improve installation efficiency over traditional roll goods, the Duro-Last X membrane is available in 10-foot wide rolls that can be custom-cut to any length up to 200 feet.
