Cool Metal roofing utilizes reflective pigments to reflect the sun's energy away the roof. Cool roofs help reduce energy consumption and also reduce urban heat island effects. Standard industry criteria for cool roofs are:
- For steep slope applications (greater than 2:12 pitch): initial minimum solar reflectance of 0.25, and 3-year aged
minimumsolar reflectance of 0.15.
- For low slope applications (2:12 or less pitch): initial minimum solar reflectance of 0.65 and 3-year aged minimum solar reflectance of 0.50.
