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.
Duro-Last is now the world's largest manufacturer of prefabricated 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.
