Calculate How Much You Can Save with a Cool Roof

Cool roofing reflects radiant energy from the sun if the roof is exposed to direct sunlight during summer days. Commercial buildings often use white roofing materials, but homes need darker colors that usually absorb more heat energy. Manufacturers have developed a variety of metal and asphalt roof materials with solar reflective properties for residential use.

Cool roofs also reduce the urban heat island effect when developed areas experience higher temperatures due to solar heat gain. Check out this calculator from Oak Ridge National Lab and Lawrence Berkeley National Lab to analyze the economic benefits of a cool roof installation on an existing home.
