Benefits of Roof Coatings ...
What are the benefits of Cool Coating Roof Systems?
- Cooler roof surface temperatures mean less heat is
transferred to the building below. Less heat in the building means it is
cooler and more comfortable in the summer since its indoor and ceiling
temperatures are lower.
- Cool coating systems can also save cooling energy.
Monitoring of more than 10 actual buildings in California and Florida with
cool roofing systems have shown 20% to 70% reductions in cooling
energy use. Cooling energy savings vary from building to building dur to
differences in roof insulation, building configuration, cooling loads, cooling
system equipment, local climate, and various other variables -- but your
cooling needs are always decreased by using a cool coating on your roof.
- Cool coatings can also help your roof last longer.
Ultraviolet (UV) rays from the sun break down many conventional roofing
materials. A cool surface reflects the sun's UV rays and slows down roof
aging.
- Roofing materials also contract and expand daily as
they heat up during the day and cool down at night. A roof with a cool
coating does not experience such large daily temperature fluctuations so it
undergoes less thermal fatigue.
- Lower roof temperatures also reduce the rate of any
chemical breakdown.
- Cool coatings can increase roof life and significantly
decrease roof maintenance and expenditures
- They also help to reduce air pollution! Direct
reductions in air pollution generated from power plants result when less
energy is used to cool a building. Widespread use of cool coatings can
also reduce the summertime warming trends or "heat island" effect in our
cities, and cooler air in cities slows down the formation of smog, beyond
reducing cooling energy needs and emission production.
- Use of cool coatings can also reduce the amount of
roofing materials produced, used, and thrown away. Eleven million tons
of roofing waste currently land in U.S. landfills each year. If cool
coatings are used to increase roof life, this waste can be greatly reduced,
and the energy and materials needed to produce new roofing can be conserved.
