Commercial Roofing Applications

In terms of High-Performance Roofing endurance is the ultimate reflection of the performance of every roofing component in terms of reliability, water absorption, wind and fire resistance, maintenance, and repair. No matter how “cool” or “green” a roof is, it still has to protect the building – for years – in all types of weather – a reality that is sometimes neglected in sustainability discussions.

If you're looking for a roof that will last, consider our track record. More than one billion square feet of Duro-Last membrane have been installed throughout the U.S. since the late 1970s – and many of these roofs are still in service. What makes a Duro-Last Cool Zone roofing system so durable? Each roof we make is:

• Resistant to water, fire, chemicals, grease, and punctures
• Able to stand up to all types of weather – including high winds and extremes of hot and cold
• Virtually maintenance free, unlike other roof materials that may require regular patching and repairs
• Reinforced with a high-density weft-insertion scrim for exceptional strength and durability
• Confidently backed by the industry’s best warranties. Duro-Last protects commercial and industrial building owners with either a 15-year full warranty or a 20-year prorated warranty.
• Both are transferable, and both provide maximum protection. Our standard warranty includes coverage for consequential damages that result from defects in the Duro-Last material and/or installation.

Thermoplastic PolyOlefin

(TPO) is a trade name that refers to polymer/filler blends usually consisting of some fraction of PP (polypropylene) , PE (polyethylene) , BCPP (block copolymer (polypropylene) , rubber, and a reinforcing filler. Common fillers include, though are not restricted to talc, fiberglass, carbon fiber, wollastonite, and MOS (Metal Oxy Sulfate). Common rubbers include EPR (ethylene-propylene rubber), EPDM (EP-diene rubber), EO (ethylene-octene), EB (ethylene-butadiene), SEBS (Styrene-ethylene-butadiene-styrene). Currently there is a great variety of commercially available rubbers and BCPP's. They are produced using regioselective and stereoselective catalysts known as metallocenes. The metallocene catalyst becomes embedded in the polymer and cannot be recovered.

In the commercial roofing industry, reflectivity and cool roofing 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, terms like sustainability, cool roofs, and cool roofing are receiving a lot of attention, and once again, Duro-Last is setting the bar.

But what does sustainability and cool roofing 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 Five E's link above 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.

Duro-Last Roofing 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.

The Duro-Last Cool Zone roofing system is an ENERGY STAR® labeled roofing system, with an initial reflectivity of 87.5% and a three-year weathered reflectivity of 86.5%, based on Energy Star testing procedures. Reflectivity or albedo is the percentage of the sun’s energy that is reflected by a surface. Another important measurement of a roof membrane’s performance is emittance Emittance deals with how effectively a surface releases heat; it is the percentage of absorbed energy that a material can radiate away. The Cool Zone’s total emittance is measured at 95%.

Duro-Shield Metal

The Duro-Shield metal retrofit roofing system is a cost-effective, single-ply roofing solution that can be installed directly over existing metal roofs. The Duro-Shield system is leak-proof, virtually maintenance-free, and backed by a comprehensive 15-year full warranty or a 20-year prorated warranty.

The Duro-Shield roofing system is the long-term way to protect your building against rain, temperature changes, interior drips, ice build-up, and rust and corrosion.
