High-tech roofs

A movement taking root in Southern Nevada represents another step forward in this nation’s quest to save energy.

As reported last month by The New York Times, “cool roof” technology is catching on throughout the country as a way to reduce energy costs. In the Las Vegas Valley that could translate to lower air conditioning bills.

Cool roofs contain materials designed to do a better job of reflecting sunlight away from buildings than traditional roofs.

The nonprofit Cool Roof Rating Council of Oakland, Calif., which evaluates the reflective value of roofing material for contractors and other interested parties, indicates on its Web site that cool roofs can cost roughly the same as traditional ones. For those cool roofs that cost a bit more, the difference is usually made up quickly in energy savings.

Although white is a common color because of its reflective advantages, cool roofs come in other colors, too, which should make it palatable to property owners.

NV Energy is doing its part to encourage cool roofs by offering energy rebates through its Sure Bet program to owners of commercial buildings that use solar-reflective roofing material.

Only three applicants in Southern Nevada have received rebates so far, according to the utility. But there is enormous potential for cool roofs to catch on in the valley because of its abundant heat and sunshine.

With all the talk about an emerging renewable energy presence in Southern Nevada, it would be wise to consider a cottage industry of cool roof technology. We would encourage more valley businesses to consider cool roofs for new structures or replacing existing roofs because the potential energy savings could be substantial.
