BERRIDGE ENERGY STAR APPROVED COOL METAL ROOF COLORS

Low Slope roofs must have an initial solar reflectance of  greater than 0.65.  After 3 years, the solar reflectance must be greater than or equal to 0.50.
Steep Slope roofs must have an initial solar reflectance of greater than 0.25.  After 3 years, the solar reflectance must be greater than or equal 0.15.

Low-Slope Roofs: Surfaces with a slope of 2:12 inches or less. (As defined in ASTM Standard E 1918-97).
Steep-Slope Roofs: Surfaces with a slope greater than 2:12 inches.
Solar Spectrum: Radiation originating from the sun, including ultraviolet, visible, and near-infrared radiation. Approximately 99% of solar energy lies between wavelengths of 0.3 to 3.5 micrometers.
Solar Flux: The direct and diffuse radiation from the sun received at ground level over the solar spectrum expressed in Watts per square meter.
Solar Reflectance: The fraction of solar flux reflected by a surface expressed as a percent or within the range of 0.00 and 1.00.
Emissivity: The emittance of a material refers to its ability to release absorbed heat. Scientists use a number between 0 and 1, or 0% and 100%, to express emittance. With the exception of a metallic surface, most roofing materials can have emittance values above 0.85 (85%). One example is a metal wrench left in the sun, which is hot to the touch because it has a low emissivity value.

While many other Berridge colors meet or exceed Energy Star’s requirements, the following Berridge colors are Energy Star Certified.
