About Duro-Last Products: Vinyl Roof Membranes Built for Strength & Durability

Duro-Last Benefits

Find out about the many benefits of choosing the Duro-Last Roofing System!

  • Proven Track Record

    Since 1978, Duro-Last Roofing, Inc. has had over 1 billion square feet of roofing installed throughout North America.

    Many of Duro-Last’s original roofs still remain intact and continue to perform exceptionally well.

  • Pre-Fabricated for Precision

    Each Duro-Last project is prefabricated to fit every roof with precision. By performing 80-85% of membrane seaming in their controlled factory environment, Duro-Last reduces the potential for rooftop installation errors and leaks.

  • Business As Usual

    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 could disrupt building activities or damage sensitive equipment.

  • Backed by the industry's best warranty

    Duro-Last is so confident in their roofing systems that they protect installations with the best warranties in the industry.

    Their standard, comprehensive 15-year No Dollar Limit warranty is transferable, has no exclusions for ponding water, and provides coverage against consequential damages that result from defects in material and/or installation workmanship.

  • Energy Efficient

    The Duro-Last white membrane is highly-reflective throughout its life span on the roof, saving significant energy and money for building owners all over North America.

  • Durable

    With a Duro-Last roofing system, high winds, snow, and other severe weather are not detrimental. Once installed, a Duro-Last roof is watertight and virtually maintenance free. The Duro-Last roofing system is also fire retardant, and resistant to chemicals, high winds, grease and punctures.
