There are cool options for nearly all types of roof coverings. There are many types of roof systems available, but the surface solar reflectance of the roofing product-the outermost layer of the roof exposed to the sun is, also known as the roof covering-determines whether the roof is cool or not. Help offset global warming by reflecting more sunlight to outer space.Decrease power plant emissions by reducing the demand for energy to cool buildings.Reduce peak electricity demand, which can help prevent power outages.
Slow the formation of smog from air pollutants, which are temperature-dependent, by cooling the outside air. Lower local outside air temperatures, thereby lessening the urban heat island effect. That is, absorbing less sunlight at the roof reduces heat conduction into the building, increasing the need for mechanical heating in winter. Beyond the building itself, cool roofs can also benefit the environment, especially when many buildings in a community have them. Decreasing roof temperature, which may extend roof service lifeĬool roofs can also incur a winter heating penalty. Improving indoor comfort and safety for spaces that are not air conditioned. Making it possible to downsize new or replacement air conditioning equipment, saving money and potentially increasing cooling efficiency. Qualifying for money-saving rebates from utilities or government programs. Helping older inefficient (or undersized) air conditioners provide enough cooling for today’s hotter summers.
