Cool Roof Coatings
Friday, January 15th, 2010It’s widely known and understood that roof coatings are often a less expensive alternative to a complete roof replacement. Coatings can not only extend the life of an existing roof system, but result in energy savings as well.
The use of light colored reflective coatings not only provide a protective barrier against ultraviolet rays that break down roof membranes, but they also can reduce the roof surface temperatures by 40 to 60 degrees Fahrenheit.
In “Potential Benefits of Cool Roofs on Commercial Buildings: Conserving Energy, Saving Money and Reducing Emissions of Greenhouse Gases and Air Pollutants,” LBNL scientists Hashem Akbari and Ronnen Levinson estimate if roofs on 80 percent of air-conditioned commercial buildings in the U.S. were coated to qualify as cool roofs (a conservative 55% aged solar reflectance), the buildings’ owners would save more than 10,000 gigawatt hours of energy annually valued at about $725 million. These energy savings also would result in an annual reduction of more than 6 megatons of carbon dioxide production, which is equivalent to the carbon dioxide emissions of about 1.25 million automobiles.
In conclusion, a quality roof coating formulated to ASTM International Performance Standards and properly selected for its intended application should provide years of service and benefit.
