How Reflector Series™ shingles work

How Reflector Series™ shingles work

GAF's cool roof assists in reducing solar heat absorption by reflecting incoming sunlight and releasing absorbed energy, contributing to the mitigation of attic heat. This has the potential to result in cost savings on air-conditioning expenses.

Moreover, you don’t have to limit yourself to light shades. The groundbreaking GAF EcoDark™ granule technology generates vibrant colors previously unseen in cool roofing.

Actual energy savings are not assured and the extent of savings can differ based on factors such as climate region, utility costs, roofing product properties, insulation quality, HVAC system efficiency, and other variables.
