Duro-Last Cool Zone® Roofing System Installed by PRO-TEK

New roof or reroof? When it comes to purchasing a roofing system, there are many factors that need to be reviewed. Some building owners want a system that is aesthetically pleasing; others look for durability. Some want a system that not only prevents leaks but also provides excellent warranty coverage. Still others prefer the roofing system that will offer the most energy-efficient benefits to them and the environment around them. This is a very important attribute to review.

Roofs make up much of the heat-retaining surface in populated areas. In some highly concentrated areas, as much as 27% of the land cover is roof surface. This can cause an “urban heat island” – a region where the temperatures can be several degrees warmer than the surrounding countryside.

Buildings with dark roof surfaces get hotter and stay hot longer. Air conditioners must work harder to maintain comfort for occupants, and demands not only on building owners for the cost of electricity, but also on power companies that supply the energy rise. A reflective roofing system can keep a building cooler and save money in air conditioning costs.

There is even a benefit for buildings that are not air conditioned, because a reflective roof will keep a building cooler and more comfortable for occupants. Moreover, there is an environmental benefit by reducing the surface area that creates heat islands. Cities such as Sacramento, Atlanta, Baton Rouge, Chicago, and Salt Lake City have already made significant strides in reducing their heat islands through the planting of trees, replacing dark pavements with lighter surfaces, and most importantly, providing incentives for building owners to utilize cool roof technology.

Studies also suggest that reflective roof surfaces reduce the damage that a roof sustains from the effects of the sun. This can also make a roof last longer.

The ENERGY STAR® Roof Products Program (sponsored by the Environmental Protection Agency) provides guidance for consumers in selecting a roofing product that suits their needs, as well as a list of products that meet the qualifications established for cool roofing products. This qualifying products list identifies low-slope roof products that have an initial reflectance of at least 65% and a reflectance of at least 50% after three years of weathering. In addition, the list supplies warranty information and company contacts.

There are several types of cool roofing products on the market. Some provide a short-term means to help keep a building cool, while others keep buildings cool AND provide a long-term waterproofing solution. The Duro-Last Cool Zone® roofing system, is the only single-ply membrane recognized by the ENERGY STAR Roof Products Program as retaining over 86% reflectivity after three years of weathering. Additionally, because 80-85% of every Duro-Last roof is pre-manufactured in our controlled factory environment, rooftop seaming is minimized, making every installation virtually leak-proof. Prefabrication also means that there is very little waste involved during installation. That means less material going to landfills and congesting our environment with waste. Furthermore, some roofing manufacturers, including Duro-Last, support environmentally-friendly efforts by recycling scrap and trim.

To determine the most cost-effective solution to your roofing problems, look at the alternatives in terms of how they will fit your building’s needs. Do you have high energy costs that you need to get under control? Do you have a roofing system that is failing and needs repair or replacement? How have previous roofing systems performed? What is the track record of the products chosen as potential roofing alternatives? When it comes to technology and experience in the cool roofing arena, has the supplier done its homework? Is the product proven? Can the supplier provide real world examples of energy savings and performance? All of these questions need to be answered to properly identify which roofing system will work best for your building needs.

Energy Savings. Long-term watertight protection. Environmental responsibility. Not every roofing system will deliver all these benefits. The Duro-Last Cool Zone® roofing system does. Before you invest in a roofing solution, research every type of system — weigh the benefits and COMPARE! It will pay in the long-run.

Duro-Last Cool Zone® Product Advantages

The benefits of a Duro-Last Cool Zone roofing system include immediate energy savings and potential energy rebates, along with the assurance that you have installed an energy-efficient roof that will protect your building and its occupants for years to come.

Higher Reflectivity That Lasts
Our proprietary thermoplastic PVC film results in a membrane that is white through and through, providing the longest lasting high reflectivity of any single-ply membrane. In fact, independent tests have shown that a Duro-Last Cool Zone roofing system loses only 1% of reflectivity after three years of weathering.

Better Protection from Mother Nature
And speaking of weathering, our mechanically-fastened, flexible system is resistant to the extremes of wind, water, heat, and cold. That’s why we offer the best warranties in the industry, with includes coverage for ponding water and consequential damages.

Potential Savings in Life-Cycle Costs
Yes, you may be able to find a roof with lower upfront costs. But upfront costs are not the whole story, especially when you factor in energy savings, energy rebates, and maintenance costs over the life of the roof.

The increased use of highly reflective, white roofing surfaces can have a significant, and immediate, beneficial impact on the nation’s energy efficiency while reducing the harmful environmental effects of urban heat islands.

Several federal, state and local initiatives encourage or mandate the use of reflective roofing systems, but the main reason so many building and facility owners continue to choose cool roofing systems is the energy savings they provide.

Our free brochure discusses the white roof phenomenon, and how the installation of our highly reflective Cool Zone roofing system delivers long-term value for virtually any flat or low-sloped roofing application.

Calculate Your Savings

Some small businesses may require more energy than others depending upon the type of business they run. These are called ENERGY-Intensive users. Curious how your facility’s energy use stacks up against similar facilities? Calculate your energy intensity.

Energy intensity is reported as the amount of energy used per square foot of space. This measurement indicates energy usage of a facility relative to buildings which have similar space usage. The less energy used per square foot, the lesser the energy usage of the facility compared to a building of the same size.

This calculator will allow you to estimate your facility’s energy intensity and the potential energy and cost savings you could realize by implementing energy efficiency upgrades. It is an estimating tool only. As with any computer analysis, the accuracy of the results depends on the accuracy and thoroughness of the data that is entered.
