"WebRoofs that are lighter in color or are reflective stay cooler than roofs that absorb sunlight. There are two ways to help cool a roof. First, a cool roof can reflect away sunlight, so it stays cooler. Such a roof is said to have a high solar reflectance. Second, a cool roof should also release or emit heat (infrared radiation) so it stays cool. " - Emissivity coating
