Energy Savings

Ultimate Roofing Systems will help you save money on your energy needs

Choosing the right roof for the job can be a powerful asset in reducing energy consumption and improving long term energy efficiency. When used with appropriately on low sloped or flat roofs, a high reflectivity, high emissivity Duro-Last Cool Zone roofing system can:

  • Reduce building energy consumption by up to 40 percent
  • Improve insulation performance to reduce winter heat loss and summer heat gain
  • Preserve the efficiency of rooftop air conditioning
  • Potentially reduce HVAC capacity requirements

Duro-Last Cool Zone roofing systems meet these “cool roofing” standards for both reflectivity and emissivity :

  • ENERGY STAR® Roof Product Program
  • Cool Roof Rating Council
  • Title 24 of California’s Energy Efficiency Standards for Residential and Non residential Buildings.

And unlike reflective coatings, the single ply monolithic Duro-Last roofing system won’t crack, peel, or wear away. Our cool roof performance is the fast, easy, and cost effective route to greater energy efficiency that lasts.

Notice that roof C (a gravel ballast built-up roof) is the same temperature as the asphalt parking lot (“D”), while roof “A” (a Duro-Last thermoplastic), remains cool.

The Five E’s of High Performance Sustainable Roofing

In the commercial roofing industry, reflectivity has been a 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 raising the bar.

But what does sustainability really mean? It means that the design, manufacture, maintenance, life-cycle impact, adaptive re-use, destruction, and recycling of roofing components help meet the long-term environmental standards demanded by today’s high-performance buildings.

For a roofing system to be considered sustainable, it must have the Five E’s of high-performance roofing: Energy, Environment, Endurance, Economics, and Engineering. In each of these areas, the Duro-Last Cool Zone system leads the commercial roofing industry.

What are the qualifications for a sustainable roof?

It is important to select a roof that delivers the Five E’s of high performance roofing:
image image image image image
ENERGY: Reduces energy use up to 40% and improves a building’s efficiency in any climate.

ENVIRONMENT: A roofing system that minimizes impact on the earth’s environment throughout the roof’s life and helps maintain healthy, productive environment inside the building.
ENDURANCE: A roofing system that meets or exceeds performance requirements for long life: all-weather reliability; chemical, fire and puncture resistance; and ease of maintenance and repair.
ECONOMICS: A roofing system that makes economic sense at the time of purchase and in the long run. A true economic comparison analyzes the cost of a roof throughout its life-cycle.
ENGINEERING: Make the most of the right materials, design and manufacturing process enable the other four E’s, resulting in a complete, integrated roofing system that can be installed quickly and easily and performs reliably over the long run.
