The Duro-Last Roofing System

Flat and Low slope Roofing Solutions

HP Roofing highly recommends the Duro-Last roofing system. As a Roofing contractor for NH VT Upper Valley area we understand the problem with flat roofs in the winter. The surface of the Duro Last system is so slick that snow and ice can be removed with a broom. We have found this product to perform exceptionally well on older homes where the issue of some puddling occurs, Duro Last has no problems with standing water as the material performs almost like a swimming pool liner, but many times tougher.

The Duro Last system can be installed over current roof. Our Qualified roofers will inspect the existing roof for presence of moisture. If none is found, we then install an underpayment of 1/2 foam board to protect the Duro Last membrane from exposure to the old roofing material to protect your warranty and enhance the insulation on the roof.

The Duro-Last roofing system membrane is a proprietary thermoplastic formulation consisting of resins and plasticizers, stabilizers, biocides, flame retardants and U.V. absorbents. A weft-insertion knitted scrim that is laminated between two layers of film gives the membrane its strength and durability. The Duro-Last membrane is available in white, tan or gray. Duro-Last can also be painted. See the General Specifications for details.

Duro-Last has met or exceeded all major fire and wind code requirements, and regional approvals as necessary throughout the country. These certifications reinforce Duro-Last’s leadership in providing the consistent, watertight integrity that building owners expect.

Duro-Last has been approved by Factory Mutual as a 1-60,1-90, 1-105, 1-150 and 1-210 roofing system. Duro-Last is also listed by Underwriters Laboratories as a UL Class A material. Evaluation services ICBO and NES have merged to form ICC-ES, which has evaluated Duro-Last for the International Building Code (IBC). The Duro-Last roofing system has been approved by the IBC and by code agency MIAMI-DADE for use in their respective jurisdictions.

Duro-Last is proud to be a charter partner of the ENERGY STAR® Roof Products Program. The ENERGY STAR label indicates to building owners and managers that the Duro-Last white membrane can save them money on cooling costs due to its high reflectivity (reflects over 86% of the sun’s energy).

Duro-Last participates in all major technical committees in the roofing industry, plus the American Society of Testing Materials (ASTM).
