Duro-Last Roofing began in 1978 when company founder John R. Burke, then the
owner of a company that made vinyl swimming pool liners, was struck by an
inspiration: If a vinyl liner kept water inside a swimming pool, why shouldn't it keep
water out, too? That simple premise became the foundation of the Duro-Last®
Further inverstigation of the roofing industry revealed that the majority of roofing
failures are not due to the roofing system assembly itself, but to poor workmanship on the job site site. To address this problem, Duro-Last brought its new roofing system "in-house", developing patented prefabrication methods and specialized equipment that allows us to complete nearly 100% of the difficult roof details and up to 85% of the roof 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. The Duro-Last Roofing System, contractor installation team, customer service and warranty all set the quality standards for the roofing industry.
Duro-Last Roofing is represented in Northern California by brothers Chris and Bob Hemphill of Division 7 Reps.
