The Duerson Corporation makes every effort to provide our customers with the most innovative and high-quality products on the market. We use only the best materials for our roofing system solutions, including one of the most energy efficient roofing systems available, Duro-Last.

To be considered “sustainable,” the Duro-Last Cool Zone roofing system meets the Five E’s of high-performance roofing standards. We’ve given a short summary of what Energy, Environment, Endurance, Economics, and Engineering mean and how the Duro-Last roofing materials we use rate in each section.

Energy Efficient Roofing

Organizations like the Environmental Protection Agency (EPA), the Cool Roof Rating Council (CRRC), and the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) have all established standards for what constitutes a “cool roof.” The Duro-Last Cool Zone reflective roofing system has exceeded these standards by providing high-emissivity roofing that may 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, and decrease the effects of Urban Heat Islands and related urban air pollution.

Environmental Considerations

According to the Oak Ridge National Laboratory (ORNL), the definition for sustainable roofing is a roof system that is designed, constructed, maintained, rehabilitated and demolished with an emphasis throughout its life cycle on using natural resources efficiently and preserving the global environment.

Besides maintaining membership with the U.S. Green Building Council (USGBC), which manages a voluntary environmental performance rating system of building components, Duro-Last also minimizes its environmental footprint in several other ways. For example, Duro-Last uses a closed-loop manufacturing process that recycles its production scrap, which in turn reduces waste; also, less fuel is required to transport the roofing system because it is more lightweight than other manufactured roofing membranes.

The Cool Zone system is also engineered in such a manner that it can be installed over an existing roof, which reduces waste, landfill space and disposal costs, and once it has reached the end of its life-cycle, the roofing system can actually be recycled into other products.

Long-Term Endurance

Despite the importance of being “green” and “sustainable,” the main function of a roof is still to protect the building long-term. The Duerson Corporation uses Duro-Last because of its long track record of durability. Installations throughout the U.S. can be noted from the 1970s, with many of the roofs still in service. The endurance of these particular membranes is evident in their resistance to water, fire, punctures, chemicals other potential hazards, as well as their high-density weft insertion scrim that provides extra strength and durability. The Duro-Last Cool zone roofing system is engineered to last and provide the sustainable, green roofing system that is so important for businesses today.

More Economical In the Long Run

The Economics section of the Five E’s highlights the importance of total life cycle costs incurred by a business owner when selecting a roofing system. These life cycle costs are meant to include energy savings as well as maintenance, repair, and removal and disposal costs.

With the Duro-Last Cool Zone roofing system, customers can expect low maintenance and repair costs, reduced installation costs due to custom factory prefabrication, protection from interior damage costs through leak-proof performance, as well as many other budget friendly benefits.

Engineering: the Key to High-Performance Roofing

The Department of Energy calls smart, coordinated engineering and design the key to the “whole-building design” of integrated subsystems and individual parts of a building into a cohesive unit that works together smoothly from “cradle to cradle.”
Throughout the Cool Zone engineering process, strict measures are in place to ensure the highest quality control is being maintained. According to the Duro-Last site, “every Cool Zone roof is engineered as a completely integrated system, prefabricated to the exact measurements of each building. Not only is up to 85 percent of membrane seaming completed in a factory-controlled environment, roof stacks, flashings, and edge details are also completed at the factory and shipped to the building site as part of the complete roofing system.” Because the roofing is precisely measured and fabricated to exact specifications before beginning the process, installation is much faster and less disruptive than other installation processes. The procedure produces no noxious fumes and is so quiet that building occupants can actually continue about their day while installation is occurring.
