Cool Reflective Coatings
Qualified roof coating products reduce the amount of air conditioning needed in buildings, and can reduce energy bills by up to 50%. The Cool Roof Program defines certain standards for solar reflectance, 3-year aged maintenance of reflectivity, and emmisivity in roof coating systems. Reflectivity is the percentage of the sun’s heat a roof keeps off a building, and emissivity is the percentage of heat a roof lets out of a building.
Lighter colored (white) roof coatings reflect the suns heat and UV rays and often lower the temperature of the roof by up to 100° degrees F. The most common cool roof coatings used over sprayed polyurethane foam (SPF) and other roof deck surfaces are light/white colored.
Cool Spray Roofing Saves you Money
•Reduces your building maintenance expenses.
•Lower your HVAC energy consumption, and save money on utility bills
•Qualify for a rebate from your utility company, or from government-sponsored energy rebate programs, which are offered in some areas of the country
•Reduce your tax burden with a tax-deductible maintenance expense •Elimenate the high cost of a roof replacement, including tear-off disposal
The most common types are:
During warmer summer months, temperatures can reach 170° degrees F on a low-slope black asphalt roof, and they can drop to -20° degrees F during the winter in northern and higher elevated regions. Much of the heat generated by absorbing the sun’s ultraviolet (UV) radiation transfers to the building interior, and can have significant adverse effects on energy consumption.
