Energy Saving White Roofs Save You $$$
For Royalty Companies, "white" refers to the color of energy saving roofs we sell that will help increase the reflectivity of heat from your roof and also help save you money by making your business cooler on the inside.
ENERGY EFFICIENCY
Duro-Last is a leader in cool roofing solutions. 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 a Duro-Last Roofing System retained reflectivity as high.

Reflectivity is a key player in talking about saving money for your commercial roof. 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 others?
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
- Engineering.
In each of these areas, the Duro-Last Cool Zone roofing system leads the commercial roofing industry. Click on the icons 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.
NO LEAKS WITH DURO-LAST
The Duro-Last membrane is classified as a CPA and is a proprietary thermoplastic formulation consisting of resins and plasticizers, stabilizers, biocides, flame retardant and UV absorbents. This membrane is then laminated to a weft insertion knitted scrim that is produced by overstitching, a non-woven web. Because of this composition and professional installation, the Duro-Last Roofing System provides you with a leak proof roof!

DURABLE
The Duro-Last Roof System is resistant to fire, chemicals, grease, high winds, and punctures, and easily accommodates wide temperature extremes. The Duro-Last Roof System has endured such devastating storms as Hurricane Hugo, and Hurricane Andrew. In 1989, 130 Duro-Last roofs remained undamaged after the force of Hurricane Hugo destroyed many buildings in the Charleston, South Carolina area.
