Timberline® Cool Series® Energy-Saving Shingles

Now get potential energy savings and cost savings when you install GAF 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. This results in less 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® Protection — to ensure the beauty of your roof against unsightly blue-green algae! (See Details)

How Cool? (See Details)

Bears In House

Thanks to the reflective nature of the Cool Series® Shingles, part of the heat radiating 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.

* Savings depend on various factors including, but not limited to, climate zone, utility rates, location, and HVAC efficiency.


A Cool Secret.

Roofing granules give a shingle its unique look and tone. But traditionally, only shingles with white granules have been considered “cool” by energy-saving standards.

Not any more. Thanks to our cool shingle process, using special proprietary cool granules with unique formulas, our shingles are highly reflective. These special granules reflect light to lower the roof temperature to help you feel cool.

Trust The Star...

Timberline® Cool Series® is an ENERGY STAR®-qualified roof product1. Here’s what it means to you:

  • Saves Money and Energy.

    According to the EPA, about $40 billion is spent annually in the U.S. to air condition buildings — one-sixth of all electricity generated in a year! ENERGY STAR®-qualified roof products may reduce the amount of air conditioning needed in buildings, and may reduce energy bills.
  • Downsizes Cooling Equipment.

    A reflective roof can reduce peak cooling demand. As a result, the home or building owner may be able to purchase a smaller, more efficient, and less expensive cooling system.
  • Decreases Pollution in Urban Areas.

    Reduced energy demand means less burning of fossil fuels, which results in less pollution from power plants. Also, ENERGY STAR®-qualified roof products help to reduce the “heat island effect,” in which dark, heat-absorbing buildings and paved areas make the air in urban areas hotter, and more smoggy.
  • May Increase Roof Product Life.

    ENERGY STAR®-qualified roof products maintain a more constant temperature, reduce thermal shock, and may help to extend the life of the roof.

1 When installed properly, this product will help reduce energy costs. Actual savings will vary based on geographic location and individual building characteristics. For more information, contact GAF Technical Services at 1-800-ROOF-411 or call 1-888-STAR-YES.
