Davis Roofing: Article About Cool Roofs
Since ancient times, white painted roofs have been used for their cooling benefits in places with warm climates, such as Greece. Similar technology can be used today on modern homes. According to the U.S. Department of Energy, a homeowner can lower the temperature of their roof by up to 50 degrees Fahrenheit with the use of a cool roof. Because less heat is being transferred into the home via the roof, owners can experience a savings in both energy and money if they have a cool roof in place. Having a cool roof on a patio can make the space much more comfortable in hot weather.
