Best Roof For Keeping Your Cool

at | Category: Roofing

ceramic-tile-roof-1Here’s something to consider: when you’re trying to keep a home cool, most folks think of air conditioning as the first line of defense. But the real first line against heat is your roof! And a hot day in the life of a good roof should include releasing — not storing and absorbing — the sun’s rays.


Traditional shingle roofing materials hold and transfer heat in a similar way. Roofing tiles made of felt-like materials overlaid with asphalt and tar will hold heat, and even transfer it downward into a structure, while other types of roofing will reflect light and heat upward and away from a building instead.


Here are some roofing materials and techniques — from the traditional to the high-tech – that have proven to work well in warmer climates.


Overlays and Radiant Barriers

Cool-roof coatings have advanced in recent years, and more developments are underway. Elastomeric sealants, foam sprays, ceramic-based paints and even “recycled waste cooking oil” treatments are making waves.


A technology on the flipside of an overlay is a roof underpinning, or sub-roof system called a radiant barrier. This under-the-roof application involves installing a reflective material, such as aluminum, or even a specialized reflective spray treatment that’s installed into an attic or space between a home’s interior and the roof. These act as barriers to keep heat up and out of a home. Costs vary from about 15 to 75 cents per square foot, but those with added insulating features can cost more. Considering the energy savings you’ll see on your utility bill, the installation fees may be worth the price.



Slate is durable and beautiful, with a natural color range, and it lasts a long time with little maintenance. Light colored and earth-toned slate help in reducing the heat absorbed by a building because it has natural reflective properties. It also wears to a nice finish over time.

Some downsides to using slate are its upscale price and heavy weight. Reclaimed or salvage slate is available in some areas, but installation and transport costs still add up.


Terra Cotta and Clay

Many regions of Spain, Mexico, Italy, the American Southwest and yes- the Houston area – have tons of heat and sunshine, and an abundance of Mission or Spanish-style terra cotta roofs. Basic clay roofs are lighter in color and therefore don’t retain the heat of darker roofs. Modern clay tiles have paint treatments to make them look like more expensive slate or traditional terra cotta and to add weatherproofing and reflective capabilities.



Less expensive than slate and clay in most cases, but more costly than traditional shingles, concrete tile is an option for warm weather durability. Concrete is heavy and takes a long time to heat, making it a good material for warm weather roofing.


Solar & Photovoltaic

If your roof is going to store heat, why not convert it into something useful – like power for your home? Photovoltaic or PV roof shingles capture and redirect solar power into electricity. Solar electric panels and shingles come in traditional shingle shapes and sizes, so adding this energy-efficient technology is not an aesthetic sacrifice as much as some of the older, bulkier rooftop panels of past decades.


White Metal Roofing

In terms of reflectivity, white metal roofing actually doesn’t perform as well as white flat and white barrel tiles. It reflects about 66 percent of the sun’s energy away from a roof. But white metal roofing does have one edge: Compared to other roofing types, it cools faster at night, and holds less heat for shorter periods. Most metal roofing will cost 20 to 30 percent more than traditional roofing, but in energy savings, durability and lowered maintenance, it is a cost saver overall
