What is a Cool Roof?

A cool roof is one that has been 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. Nearly any type of building can benefit from a cool roof.

Just as wearing light-colored clothing can help keep you cool on a sunny day, cool roofs use solar-reflective surfaces to maintain lower roof temperatures. 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.

Benefits of Cool Roofs Installed by Creative Energy Solutions

  • Reducing energy bills by decreasing air conditioning needs.
  • Improving indoor comfort for spaces that are not air conditioned.
  • 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.
  • Reduce local air temperatures (sometimes referred to as the urban heat island effect).
  • Lower peak electricity demand, which can help prevent power outages.
  • Reduce power plant emissions, including carbon dioxide, sulfur dioxide, nitrous oxides, and mercury, by reducing cooling energy use in buildings.
