With the climate getting warmer in most parts of the country, you might be wondering what you can do to help keep your house cool. Most commercial buildings have been enjoying the cooling effects of their roofs for some time, since their single-ply membranes are often white, which reflects heat away. ‘Cool roofs’, are often either composed of a light-colored material, such as the granules on shingles, or are painted a light color, such as some metal roofing.
Below are Energy Star rated and/or Cool Roofing Rating Council (CRRC) approved roofing products that we carry that help keep your house cool when it’s hot outside.
Asphalt shingles are the most common residential roofing product, so we’ll start with those. Of those, Owens Corning is the most popular asphalt shingle manufacturer. They offer 3 shingles at 3 price points that are Energy Star rated – Supreme, Oakridge, and TruDefinition Duration.
Their most affordable ‘cool roof’ asphalt shingle is their Supreme. This is a 3-tab shingle with a 25-year limited warranty and wind rated at no more than 60 mph. If cost is your most important factor in choosing a cool roof, Owens Corning’s Supreme shingles are a good choice. Next up is Owens’ Oakridge. These are architectural shingles with a limited lifetime warranty and a 110/130 mph wind rating. If you can afford to spend a little more, these are a better shingle. Lastly, their TruDefinition Duration is their best Energy Star shingle. It includes the same features their Oakridge has, plus Owens’ SureNail technology, which helps the installer secure each shingle to your roof faster, and helps keep the shingles down during high winds. All 3 of these are only available in their ‘Shasta White’.
CertainTeed is another a well respected shingle manufacturer that we carry. They offer two ‘cool roof’ asphalt shingles. Their Presidential Solaris® is designed to resemble wood shake, has a UL Class A fire resistance rating, offers a Lifetime limited transferable warranty, and a 15-year 110 mph wind-resistance warranty (upgradable to 130 mph).
Landmark Solaris® is the cool roof version of CertainTeed’s popular Landmark shingle. It, too, has a UL Class A fire resistant, offers a Lifetime limited transferable warranty, and a 15-year 110 mph wind-resistance warranty (upgradable to 130 mph).
Be sure to check on their website if either of these Energy Rated roofing products are available in your area.
Another popular asphalt shingle manufacturer is GAF. They offer a solid product with a great warranty. GAF currently offers 3 cool roof asphalt shingle products – their Timberline HD in white, Royal Sovereign® in white, and their Timberline Cool Series
Antique Slate, Barkwood, Weathered Wood
Although less expensive than Owens Corning, TAMKO still makes a great asphalt roofing shingle. They offer 2 that are Cool Roof Rating Council approved – their lesser expensive 3-tab shingle Elite Glass-Seal 3-tab in white or glacier white and their laminated Heritage in Glacier White. As with CertainTeed, check Tamko’s website or ask us for available in your area.
You wouldn’t think that a metal roof could help keep your house cool, but it can as long as your house has adequate insulation and you don’t have air leaks or windows that aren’t energy efficient. A lot goes into an energy-efficient home. A metal roof reflects heat away from your home, which helps to reduce your utility bill in the warm Summer months. As our climate is getting warmer, this is becoming more important. Oddly enough, the color of your new metal roof doesn’t have to be a highly reflective color, such as white or galvanized :-).
Clay roofing tiles are a natural ‘cool’ roofing product simply because they breathe. The material itself is porous which allows air to move through them. The space beneath the tiles also let warm air move up your roof and out through the ridge cap at the top. All the while letting rain or melted snow flow over the top of your clay tiles safely to your gutters. Boral Roofing makes several clay tiles that are CRRC approved.
Romano Pans trace their roots to the ancient Greeks with their alternating flat panels and half-barrels. The classic barrel 1-piece ‘S’ Tile. ClayMax is Boral’s lightweight low-profile barrel tile. ClayLite designed especially for re-roofing. 2-Piece Mission barrel tiles that dates back to the Bronze Age. 2-Piece Monarch authentic Mediterranean style with its small-barrel and high-arch.
Whatever your style or budget, there’s a cool roof option for you, be it asphalt shingles, metal sheets, or clay tiles. If your roof is ready to be replaced, now is a great time to consider a ‘cool roof’.
As of the time of this writing, only 3 of the above manufacturers offer Energy Star Rated or Cool Roofing Rating Council (CRRC) approved roofing products in our area (Front Range, Colorado) – Owens Corning, Flatiron Steel, and Boral Roofing. That said, do keep an eye on the others, as they may offer their cool roof products in your area.
