Sierra Roofing & Construction
Authorized Duro-Last Installer
As an authorized installer of the "World's Best Roof"; we draw on the expertise of Duro-Last's designers, engineers, and quality control technicians to ensure that every roof is installed to it's specifications.
Every Duro-Last project is prefabricated to fit each roof precisely. By performing 80-85% of membrane seaming in our controlled factory environment, Duro-Last reduces the potential for rooftop installation errors and leaks. The Duro-Last roofing system is perfect for any flat, low-sloped, new or retrofit application. Additionally, our standard, comprehensive 15-year No Dollar Limit (NDL) Warranty is the best in the industry. It's transferrable, has no exclusion for ponding water, and provides coverage against consequential damages that result from material defects and the authorized contractor's installation of Duro-Last products.
Installation is quiet and safe, without loud machinery, hazardous materials, noxious fumes, hot tar or mess. A new Duro-Last roofing system can often be installed over an existing roof without an expensive tear-off, virtually eliminating debris that can disrupt building activities or damage sensitive equipment.
