What is a Cool Roof?

Just out from the California Energy Commission is a brochure regarding Cool Roofs. This is helpful information and provides some understanding of how a roof is determined to be "cool" and how it affects Title 24 energy compliance. The direct link to the brochure is here below:


You can also access the file by following these steps:

  1. Log onto the California Energy Commission's Website
  2. Under the Brochures Heading, click on the "Cool Roofs" brochure.
  3. Select "Landscape" orientation in your print properties settings if printing two-sided (duplex).

I hope this is helpful to you in understanding the definition and requirements of a "cool" roof.

As always, I am available to discuss the process of meeting the California Energy Code for any building project. Contact me …
