Roof
According to the EPA, about $40 billion is spent annually in the US to air-condition buildings – one-sixth of all electricity generated in a year! ENERGY STAR qualified roof products reduce the amount of air conditioning needed in buildings, and can reduce energy bills by up to 50%.
A reflective roof can reduce peak cooling demand by 10-15 percent. As a result, the home or building owner may be able to purchase a smaller, more efficient, and less-expensive cooling system.
Reduced energy demand means less burning of fossil fuels, which results in less pollution from power plants. Also, ENERGY STAR qualified roof products help to reduce the “heat island effect” in which dark, heat-absorbing buildings and paved areas make the air in urban areas hotter, and more smoggy.
Energy Star® qualified roof products maintain a more constant temperature and reduce thermal shock, which occurs when cool rain hits a hot roof, causing a sharp drop in temperature. During temperature changes, a roof expands and contracts, causing stress and degrading the roof.
