Duro-Last®Precision-fabricated, Watertight Protection for Flat Roofs and Low-Sloped Roofs

Duro-Last® Building

The Duro-Last® single-ply flat roofing system is ideal for any low sloped or flat roof design. Since 1978, over
a billion square feet of Duro-Last® membrane have been installed on buildings of all types. The Duro-Last® roofing system is:

  • Precision-fabricated to fit your building's low-sloped or flat roof. Every Duro-Last® roof is manufactured to exact size in our controlled factory environment. This eliminates up to 85% of rooftop installation seaming and ensures an excellent fit, delivering worry-free, leak-proof, long-term protection for any low-sloped or flat roof design.
  • Energy efficient. The Duro-Last® white membrane has the highest retained reflectivity of any single-ply membrane rated by the EPA's ENERGY STAR® Roof Products Program, saving significant energy and money for facilities with low-sloped and flat roofs throughout North America.
  • Durable. The Duro-Last® roofing system is resistant to fire, chemicals, grease, high winds, and punctures, and easily accommodates wide temperature extremes. Installed by authorized contractors. A Duro-Last® installation on your building's low-sloped or flat roof is quiet and safe, without loud machinery, hazardous materials, noxious fumes, hot tar or mess. A new Duro-Last® roofing system often can be installed over an existing roof without an expensive tear-off.
  • Backed by the 15-year or 20-year full warranties for low-sloped or flat roofs. Duro-Last® protects the commercial and industrial building owner with either a 15-year full warranty or a 20-year full warranty. Both warranties are transferable, and both provide maximum protection. Our standard warranty includes coverage for consequential damages that result from defects in the Duro-Last® material and/or installation.
