Timberline® Cool SeriesEnergy Saving ShinglesNow get potential energy savings (and even tax credits) when you install GAF-Elk Timberline® Cool Series Shingles. Thanks to modern reflective technology, you can join the green revolution with Cool Series roofing shingles. Our highly reflective shingles can help to reduce temperatures in your attic, so your home will stay cooler in the summer—to save on air conditioning costs. Simply put, our Cool Series shingles use specially-designed roofing granules that have greater reflectance than traditional shingles. The result is, it minimizes the transfer of heat to the space below—to keep you cooler in the summer. Not only that, Timberline® Cool Series shingles are made with the patented StainGuard® algae protection to assure the beauty of your roof against unsightly blue-green algae! How Cool?*
Thanks to the reflective nature of the Cool Series Shingles, part of the heat coming from the sun gets reflected, reducing the heat in the attic, and heat going into the house. It may translate into substantial savings in air conditioning bills. Cool roofs may save residents an avg. 7-15%** of total cooling costs, depending on geography, structure and climate. In warmer climates, cooling-cost savings may be greater year round. A cool roof minimizes the solar heat gain of a building by first reflecting incoming sun rays and then by quickly re-emitting the remaining absorbed portion. As a result, the cool roof stays cooler than a traditional roof of similar construction.
*Results may vary by geography, season and property.
A Cool Secret.Roofing granules give a shingle its unique look and tone. Not any more. Thanks to our technology, cool granules are covered with multiple layers of reflective material. That means thousands of mini-reflectors working to make you feel cool! Trust The Star...Timberline® Cool Series is an Energy Star® qualified roof product. Here’s what it means to you:
