The Duro-Last prefabricated single-ply roofing system is ideal for virtually any commercial or industrial, flat or low-sloped application. The highly-reflective white membrane delivers real energy cost savings for building owners and managers. Extremely durable and easily installed without disruption to daily operations, the Duro-Last roofing system is also leak-proof, resistant to high winds, and virtually maintenance-free.Since 1978, over a billion square feet of Duro-Last membrane have been installed on buildings of all types, with millions more being installed every year. The Duro-Last roofing system is:

The World’s Coolest Roof

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 of all types throughout North America.The Duro-Last Commercial Roof reflects up to 86% of the sun’s rays, resulting in saving up to 35% on energy costs! The Duro-Last Roof System has been approved by Energy Star. Of the white, single-ply products rated by the Energy Star program, only the Duro-Last Roof System retained reflectivity this high.

Rooftop Sustainability
In the commercial roofing industry, reflectivity has been the dominant discussion point for several years, and the Duro-Last® Cool Zone® roofing system has set the standard for single-ply roof reflectivity and the resulting energy savings. Now the term “sustainability” is receiving a lot of attention, and once again, Duro-Last is setting the bar.

But what does sustainability really mean for building owners, facility managers, contractors, architects, and other specifiers? It means that the design, construction, maintenance, life-cycle impact, adaptive re-use, destruction, and recycling of roofing components must help meet the long-term environmental standards demanded by today’s high-performance buildings.

To be considered “sustainable,” a roofing system must meet the Five E’s of high-performance roofing: Energy, Environment, Endurance, Economics, and Engineering. In each of these areas, the Duro-Last Cool Zone roofing system leads the commercial roofing industry. Click on the icons below to learn more about the Five E’s and how the Duro-Last Cool Zone roofing system delivers on the multiple demands of high-performance roofing.

There are good reasons to choose metal roofing, including lower initial installation costs and superior protection against fire.

But time catches up with everything, including metal roofs. Years of exposure to the elements, hot and cold extremes, and rust and corrosion can combine to compromise your metal roof’s integrity.

In fact, if your metal roof is more than a few years old, you probably know the frustration of leaky buildings and escalating maintenance costs.

And you’re not alone. With over 60 billion square feet of metal roofing in place in the United States and two billion more installed each year, that adds up to a lot of leaks – and a lot of money spent fighting them.
