Duro-Last Roofing

Reasons to Choose Duro-Last

Factories, schools, churches, government offices, and businesses of all types have chosen Duro-Last because our roofing system is:

Prefabricated.

Every Duro-Last roof is measured and manufactured to exact size, accommodating every rooftop penetration. Prefabricating the roof in a controlled factory environment eliminates up to 85% of seaming that's done on-site during roof-top installation and improves the long-term performance of the roof. This precise attention to detail ensures an excellent fit and delivers worry-free, leak-proof protection. Duro-Last can even assist Nasi Roofing 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 pooling water and helps solve roof problems before they can occur. With Duro-Last's 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 as installation is quiet, fast, and safe. There are no loud machines, no hazardous materials, noxious fumes, hot tar, or 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's written 15 or 20 year commercial warranties provide our customers with maximum protection. While other roofing manufacturers offer limited warranty coverage, Duro-Last provides the world's best material and labor warranties. No small print and no additional cost to you.

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 US Environmental Protection Agency. Energy Star has approved a wide variety of cool roofing products, all with different levels of reflectivity, performance characteristics, and warranties.

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 procedures). This high, sustained reflectivity is saving significant energy and money for building owners all over the US, and because the Roofing System is mechanically-attached, insulation can be placed under the membrane during the installation of the roof, reducing heat loss in the winter.

Customer Testimonial

Duro-Last roof

"As the Maintenance Lead of Vilas county, I am writing a reference letter for Nasi Roofing and the Duro-Last Roofing System. With another successful roofing project performed by you. I wanted to express what a pleasure it was to work with you and your team of installers. This is the third project that the County has hired Nasi Roofing to install the Duro-Last Roofing System. The durability of the membrane is awesome. We had installed the first roof in 2000. it was inspected in 2015 with very little wear. I thank Nasi Roofing and their team for their hard work, especially with respect to follow ups after storms during the project. I look forward to doing business with future projects."
