Duro-Last, Inc. began in 1978 with the simple need to find a roofing system that worked. Existing roofing systems presented a common problem - they required ongoing maintenance and continual expense, with no long-term solution in sight. Investigation of the roofing industry proved that the majority of roofing system failures then (and still today) is not due to the roofing system assembly itself, but to workmanship onsite. To solve this problem we brought our roofing system "in-house," developing custom prefabrication methods and specialized equipment that allows us to complete the difficult details with custom prefabricated accessories. The result is lower on-site labor costs and better installation quality. Duro-Last is now the world"s largest manufacturer of prefabricated roofing systems. The Duro-Last Roofing System, contractor installation team, customer service and warranty all set the quality standards for the roofing industry.
