Cool Roofs

Made of reflective paint, tiles, or shingles, a cool roof can stay more than 30 percent cooler than a standard dark roof by reflecting more sunlight and absorbing less heat. So it can help you lower your air-conditioning costs and conserve energy. Pretty cool, huh?

Cool Benefits

Cool BenefitsWhen many buildings in a community have cool roofs, it can lesson what is called the “urban heat island effect,” which is the phenomenon of buildings soaking up the sun’s radiation and then re-radiating that heat after sundown. According to the U.S. Department of Energy, lowering the amount of energy used to cool buildings “reduces local air temperatures; lowers peak electricity demand, which can help prevent power outages; and reduces power plant emissions, including carbon dioxide, sulfur dioxide, nitrous oxides, and mercury.”

Cool Savings

Cool SavingsMany types of cool roofs are the same price as standard roofs and some utility companies offer rebates. Beyond that, you’ll enjoy savings from a lower air-conditioning bill year after year. You can also receive up to $500 in a federal tax credit for a cool roof.

Cool Roof Types

Cool Roof TypesThere are many different cool roof systems for both existing and new roofs. They all use thick coatings with reflective pigments. Some also offer restorative features and water protection. The Cool Roof Rating Council is a nonprofit organization that was created to conduct third-party tests and give accurate ratings on cool roof systems. You can search their online Rated Products Directory to compare options and find the cool roof that meets your needs. Check it out – it’s free!

Cool Walls, Too

Cool WallsYou can also use reflective paint on your exterior walls to cool your house – especially if you live in a warm climate. These “cool paints” are on the Federal Energy Management Program’s Promising Technologies List, which prioritizes technologies that help save energy but are underused. Learn more about cool paints.

    My husband and I want to put a cool roof coating on top of our existing roof since it is still functional and probably won’t need to be replaced for another decade anyway. Do you know if those coatings are just as effective as getting a completely new cool roof? We really hope so, because we’d rather not throw out the perfectly good (albeit heat absorbing) roof we already have.

    Thanks for the post. This is really neat information. I really like the idea to have the suns rays bounce off of the roof. I can see how that can really help to make sure that the roof stays cool. I think talking with a roofing contractor would be a great idea to make sure that you get the right product for your home.

    One of the first things I want to do to my new house it replace the roof! I’d actually never heard of a cool roof before. I would totally be willing to look into something that will keep my house 30% cooler. This post mentioned that these roofs can be made of tiles or shingles. How do you choose which material will work best for your home?

    Great post. I have read about the cool roofs before, but have yet to really hewn in on them as you put it. Thanks for writing this article. My partner and I are always looking to add things to our company, and we are looking at some different energy efficient options. We have owned and operated a roofing company inc charlotte nc for many years now, and are always looking to innovate. I am glad I bumped into this. Thanks!

    I never realized there were so many roof types, and tricks to them. I especially like the tip to use reflective paint. If I ever move to a warmer climate, I will have to remember to look for cooler paints for my roof. Hopefully more companies and homes will realize the benefits to having cooler roofs.
