Cool Roof FAQs

Summers are hot here in Texas, and it’s easy to rack up a big electric bill trying to keep your house cool during the months of May through October. Smart homeowners are always looking for new ways to keep their homes cool without spending a fortune. Did you know that you can save on cooling (and heating) costs by installing an energy-efficient or “cool” roof? Here, we’ll go over some commonly asked questions about cool roofs.


Q: What is a “cool” roof?
A: A cool roof is a roof that helps conserve energy and reduce cooling costs of the building it covers. A cool roof is constructed with shingles or tiles that have a higher level of solar reflectance and higher thermal emittance. In other words, these materials are better able to reflect the sun’s heat and to release any remaining heat that is not reflected. Cool roofs are made from a variety of materials, including asphalt fiberglass, metal, or polymers.

Q: How are tiles made more energy efficient?
A: Often, reflective tiling is used in order to keep the roof from absorbing heat during the summer months. Since darker materials will absorb more heat (think of stepping on blacktop barefoot during summer), lighter-colored roofing materials are often used. Alternatively, paints and coatings can be applied to darker tiling to make it reflective.

Q: How much can I save with a cool roof?
A: Depending on the area where you live, the shape of your roof, and the time of year, you can save as much as 70% on cooling costs during the summer. In cooler areas or in places where the sun is less intense, the range is a bit lower, but usually you can expect at least 20%.

Q: How much does it cost to install a cool roof?
A: A cool roof isn’t necessarily more expensive than any other roof. That said, if you plan to retrofit an existing roof with reflective coating or other materials, it could get a little pricey. The cost depends on the materials you’re using, the size of the roof, and the roofer you have doing the retrofit. Ultimately, it could be well worth the cost if it results in large energy savings for the life of the roof.
