A cool roof is a system that provides high solar reflectance (reducing heat transfer to the building) and high thermal emittance (radiating absorbed heat). Cool roofs are usually white or light-colored. Designed to reflect sunlight and absorb less heat, cool roofs can be made of highly-reflective materials or covered with liquid-applied products, including waterproofing coating systems.
Cool roofing delivers immediate and long-term benefits, including:
- significant savings on operating costs for air conditioning
- longer life-expectancy for your roof
- environmental protection: lowers emissions/pollution, reducing greenhouse effects and urban heat island effects.
- better thermal control for special-needs building (food stores, buildings without AC, animal farms)
