Cool Roofing products are specifically designed to reflect and emit heat and UV rays away from your roof surface. This can lead to substantial savings for those who take advantage of these benefits.
Lower the temperature of your roof up to 60° during summer weather, save energy and get valuable incentives when you install a cool roof on your existing or new buildings.
Although there is no industry-wide definition of a cool roof, the EPA's Energy Star Roof Products Program has established a minimum standard, requiring that low-slope roof products have an initial reflectance of at least 65 percent and a reflectance of at least 50 percent after three years of weathering.
The Cool Roof Rating Council (CRRC) is a non-profit association that has established performance ratings for solar reflectance and emittance from roof surfaces. All tests are performed by accredited, independent laboratories and follow established American Society of Testing Materials (ASTM) protocols.
There are three primary types of cool roofing products on the market: protective paints and coatings, green roofs and single-ply roofing systems.
Important factors to consider when selecting a cool roofing system:
Reflectance/emittance performance, both initially and after three years.
Long-term track record of durability and performance.
A good warranty backed by a well-established manufacturer.
Climate and weather extremes in a given location.
Maintenance requirements and ease of repair.
