DURO-LAST® OFFERS COMMERCIAL ROOFTOP WARRANTIES THAT SET THE INDUSTRY STANDARDS

Watertight Exteriors DuroLast Roofing SystemBecause the Duro-Last roofing system contains the highest quality materials and undergoes stringent quality control checks during its manufacturing process, we have total confidence that it will provide years of leak-proof protection. We back our confidence by providing the most comprehensive warranty available: a 15-year full labor and material warranty. Duro-Last also has 20-year warranties available.

  1. LABOR AND MATERIALS INCLUDED On a Duro-Last roof (for warranty related repairs or replacement), you pay nothing for materials or labor.
  2. PONDING WATER Duro-Last's standard 15-year labor and material warranty contains no exclusions for ponding water.
  3. CONSEQUENTIAL DAMAGES COVERAGE Our standard warranty includes coverage for consequential damages that result from defects in the Duro-Last material and/or installation.
  4. TRANSFERABLE The standard Duro-Last warranty is transferable at no charge to a new building owner.
  5. ISSUED BY THE MANUFACTURER Duro-Last warranties come straight from the manufacturer that has produced over a billion square feet of roofing membrane since 1978. These warranties are in addition to any warranty your roofing contractor may provide.
  6. NO CHARGE There is no additional charge for your Duro-Last standard warranty. That means you get the industry's best rooftop protection for FREE.
  7. NO MAINTENANCE PROGRAM REQUIRED Although regular common sense maintenance can extend the life of your roof, Duro-Last does not require you to invest in a roof maintenance program (often stipulated by other manufacturers) for your warranty to be in effect for the entire 15-year period.
