Q: What is a cool roof?

A: A cool roof is a combination of a reflective roof surface (usually a lighter-colored shingle) that is held slightly above the roof deck (or sheathing) to allow passive air ventilation underneath the shingles; a cool roof system also may include the application of insulation in the roof rafter cavities. The goal is to keep the roof surface from becoming excessively hot and transferring that heat to the attic or conditioned living spaces, thus reducing the burden on the home’s cooling system and energy use.
