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 or low-sloped 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.

Installation is less disruptive than a shingle or metal roof.
You will hardly know we are there. No loud machinery, no noxious fumes, no potential damage by rain getting in during installation, no messy splatters of tar to clean up,
it can be installed in less time saving labor cost and intrusion to the home or work space, or classroom.
The Duro-Last Duro-Tuff roll roofing system 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. See the Fact Sheet 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 is also a charter member of the Cool Roof Rating Council (CRRC) and a member of the United States Green Building Council (USGBC).
Duro-Last participates in all major technical committees in the roofing industry, plus the American Society of Testing Materials (ASTM).
