The Benefits of Cool Roofs

The term "cool roof" refers to how much it reflects and emits the sun's heat back to the sky instead of transferring it to the building. According to the Cool Roof Rating Council (CRRC), "Coolness" is measured by solar reflectance and thermal emittance. The higher the value, the "cooler" the roof.

A cool roof is either white or is another "cool" color which use darker-colored pigments that are highly reflective in the near infrared portion of the solar spectrum. It is like wearing a light shirt versus a dark shirt out in the sunshine: the light shirt keeps you cooler.

Benefits of a Cool Roof are numerous and include:
  • Energy savings and global warming mitigation
  • Reduction in urban heat island effect and smog
  • Improved occupant comfort
  • Comply with codes and green building programs
Washington Roofing & Insulation provides free on site consultation to help you determine which cool roof product is right for you.
