A cool roof is designed to reflect sunlight and absorb less heat. They are an energy-efficient solution that uses reflective tiles, sheet coverings, or paint to reduce heat intake. Normal and dark roofs can reach high temperatures of over 150 degrees. Cool roofs reduce this amount by over 50 degrees, helping to conserve energy and reduce utility costs. Energy-efficient roofing can be easily identified by the Solar Reflective Index or SRI. This measures the material’s ability to absorb sunlight through reflection.
