Just as wearing light-colored clothing can help keep you cool on a sunny day, cool roofs material that is designed to reflect more sunlight and absorb less heat than a standard roof. Cool roofs can be made of a highly reflective type of paint, a sheet covering, or highly reflective tiles or shingles. Standard or dark roofs can reach temperatures of 150°F or more in the summer sun. A cool roof under the same conditions could stay more than 50°F cooler and save energy and money by using less air conditioning.
A cool roof can benefit a building and its occupants by:
1. Reducing energy bills by decreasing air conditioning needs
2. Improving indoor comfort for spaces that are not air-conditioned, such as garages or covered patios
3. Decreasing roof temperature, which may extend roof service life.
Beyond the building itself, cool roofs can also benefit the environment, especially when many buildings in a community have them. Cool roofs can:
1. Reduce local air temperatures (sometimes referred to as the urban heat island effect)
2. Lower peak electricity demand, which can help prevent power outages
3. Reduce power plant emissions, including carbon dioxide, sulfur dioxide, nitrous oxides, and mercury, by reducing cooling energy use in buildings.
TYPES OF ROOFS AND HOW THEY CAN BE MADE COOL
There are many types of roof systems available, but the surface exposed to the sun is the one that determines if a roof is cool or not. You can usually make a new or existing roof cool by selecting the appropriate surface.
