Natural Energy-Saving Benefits of Tile Roofs Help Reduce Energy Costs

Tile Roofing Institute to Discuss New Research on Energy Efficient Properties of Concrete and Clay Tile Roofs

CHICAGO – New research shows that the energy-efficient properties of concrete and clay tile roofs play a key role in helping reduce energy costs. Working with the Oak Ridge National Laboratory (ORNL), the Tile Roofing Institute (TRI) sheds light on the unique, energy-saving properties of tile roofing systems, what makes it a cool roofing product and how builders and homeowners can benefit. To learn more, visit the Tile Roofing Institute at the Building Systems Councils booth at the International Builders Show in Orlando, Feb. 7 to 10, booth W2689.

Energy Efficiency – It’s More Than Just Color

Historically, experts have promoted tile roofing’s cool, energy-saving properties. Light- or white-colored roof tiles were shown to cool the house beneath it by reducing the amount of heat transferred from outside to inside. The problem was that builders weren’t able to sell homebuyers on light-colored tile roofs as most people preferred their roofs to be darker in color.

What’s now known is that properties other than color make tile an even better cool roofing option, potentially saving homebuyers additional energy and money. Research from ORNL shows that tile roofing’s mass, reflectivity and ventilation beneath the tiles contribute to a reduction of heat transference of at least 50 percent, when compared to a traditional asphalt shingle roof. Coated clay tiles can cut the transfer of heat by up to 70 percent.

As more evidence is found, green building and government energy programs are feeling pressure to consider tile roofing in a home’s environmental rating. In his ORNL research, William Miller, Ph.D. notes, “The Environmental Protection Agency, the Leadership in Energy and Environmental Design (LEED) program and many state energy offices should offer energy credits for roofs using sub-tile venting and cool pigmented colors.”

Tile’s Durability Also Saves Money

In addition to its energy-efficient properties, tile roofing is highly durable. Installed properly, tile roofs can withstand harsh weather conditions including high winds, snow and ice build-up, hail and earthquakes. Additionally, tile roofing is naturally fire-resistant.

With tile’s strength and ability to stand up to the elements, it requires relatively few repairs compared to asphalt shingle roofing. According to TRI Technical Director Rick Olson, because tile is inherently durable, tile roofs can last much longer than shingle roofs. “Tile roofs can last decades,” notes Olson. “In Europe, where tile roofs are common in a variety of climates, it’s not unusual to find buildings with tile roofs that have lasted centuries.”
