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 here.

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.
