What Color of Roofing Heats and Cools the Best?

Light-colored roofs reflect more heat away from a building.

Colors That Cool

Lighter roofing colors such as white or light tan reflect more solar radiation than darker ones, according to Virginia Cooperative Extension. This means the house absorbs less heat, and energy costs to cool the house will be reduced, as well.

Colors That Heat

Dark-colored roofs absorb solar radiation. Black or brown roofs trap heat, cause a rise in building temperature and can lower heating costs, according to the University of Oregon.

Bottom Line

Light-colored roofs cool the best while dark-colored ones provide the most heat. Consider using roofing materials that incorporate new technology such as cool-color pigments. These combine the advantages of light- and dark-colored roofs. They may be a good option for those who want the look of a dark-colored roof with the benefits of cooling properties.
