All types of business have chosen Duro-Last because:

  • Prefabricated. Every Duro-Last roof is measured and manufactured to exact size, accommodating every rooftop penetration. Prefabricating the roof in our controlled factory environment eliminates up to 85% of seaming that is done on-site during roof top installation, and improves the long-term performance of the roofing system. This precise attention to detail ensures an excellent fit and delivers worry-free, leak-proof protection. Duro-Last can even assist your architect, facilities or maintenance personnel in developing specifications for your roofing project.
  • Durable. The Duro-Last roofing system is resistant to fire, chemicals, grease, high winds, and punctures, and easily accommodates wide temperature extremes. Duro-Last’s custom flashing resists ponding water and helps solve roof problems before they can occur. Plus with Duro-Last’s available Roof-Trak® protective walkway system, heavy equipment, and maintenance traffic are easily managed.
  • Installed with no disruptions. Building occupants will hardly know a new roof is being applied, because installation is quiet, fast, and safe. There are no loud machines, no hazardous materials, no noxious fumes, no hot tar, and no mess. In many cases, a new Duro-Last roofing system can be installed over an existing roof without an expensive tear-off, virtually eliminating dust or falling debris that might interfere with building activities or damage sensitive equipment.
  • Backed by the industry’s best warranties. Duro-Last protects commercial and industrial buildings with a comprehensive 15-year full warranty or a 20-year prorated warranty. Both provide maximum protection, including coverage against damage caused by ponding water, and coverage against consequential damages that result from defects in the Duro-Last material.
  • Energy-efficient. Duro-Last is a leader in cool roofing solutions, and has introduced the Duro-Last Cool Zone® brand to address the growing nationwide interest in energy efficient roofing systems. Duro-Last is proud to be a “charter partner” in the ENERGY STAR® Roof Products Program, sponsored by the U.S. Environmental Protection Agency.

Of the white, single-ply products rated by the ENERGY STAR program, only the Duro-Last Cool Zone roofing system has retained reflectivity of greater than 85% after three years of weathering (based on ENERGY STAR roof products testing criteria). This high, sustained reflectivity is saving significant energy and money for building owners all over the United States. Furthermore because the Duro-Last roofing system is mechanically-attached, and insulation can be placed under the membrane during the installation of the roof, reducing heat loss in the winter.
