GAF Timberline HD® Cool Colors Reflective Shingles
Energy Star Rated Roofing Options
The revolutionary new GAF Timberline® HD Cool Color Series combines the visual impact of shingles into the first energy-efficient “cool” asphalt shingle offered in a palette of rich, organic colors.
These remarkable shingles slow heat build-up for a more energy-efficient home. The Cool Color Series is composed of highly reflective granules that bounce back the sun’s rays and more effectively release absorbed heat.
Timberline® HD Cool Color Series shingles carry a 40-year limited warranty with an option for limited transferability and a limited wind warranty of up to 110 mph for all GAF Timberline® HD Cool Color Series.

Note: It is difficult to reproduce the color clarity and actual color blends of these products. Before selecting your color, please ask to see several full-size shingles.
Energy Star® Roofing Products
ENERGY STAR® labeled roof products can help you save money and the environment by reducing your energy use. They work by reflecting more of the sun’s energy back into the atmosphere, keeping your building cooler and reducing your air conditioning bills. Because much of the United State’s electricity is generated by burning fossil fuels, creating air pollution, reducing the amount of energy needed to cool buildings helps to reduce the production of air pollutants.
What is an ENERGY STAR labeled roof product?
It is a reflective roof product that lowers roof surface temperature by up to 100 degrees Fahrenheit, thereby decreasing the amount of heat transferred into a building’s interior. ENERGY STAR-labeled roof products save money and energy by reducing the amount of air conditioning needed to keep a building comfortable.
Cool Roofs
Cool roofs feature a highly reflective outer surface that reduces the amount of heat conducted through the roof. On a sunny day, ENERGY STAR–labeled cool roof products typically lower the roof surface temperature by 50° to 70° Fahrenheit (F), thereby decreasing the amount of heat transferred into a building.
Benefits of Cool Roofs Include:
- Downsized air-conditioning equipment. A cool roof can reduce peak cooling demand by up to 40 percent in warm climates, although in cold climates the heating load penalty may offset the cooling energy savings. Typical energy savings run around 20 percent, with simple payback periods of a few years.
- Extended roof life. Cool roofs tend to last longer because they are less susceptible to thermal expansion and contraction. Less heat absorption also helps the roof resist degradation by ultraviolet light and water.
- Reduced heat island effect. Nonreflective roofs can heat the air around them in a process known as the heat island effect. This phenomenon can raise the cooling demands of buildings and vehicles in a wide area, contributing to smog, elevated ambient temperatures, and associated health problems.
Energy savings from installing ENERGY STAR® or Cool Roofs Rating Council–labeled roof products depend on the local climate, existing insulation levels, the type of roof replaced, the type of roof installed, and maintenance. In the best applications, cool roofs have no incremental cost and deliver a nearly instant payback. In the wrong applications, the payback may be unacceptably long. Generally cool roofs are most cost-effective when:
- A roof is being installed as part of new construction or needs to be replaced on an existing building.
- Older, inefficient HVAC equipment needs to be replaced.
- The building is a flat-roofed, low-rise, air-conditioned commercial facility.
- There is little or no existing roof insulation.
- The climate is hot and sunny, at least in summer.
