Cool Roof 
 
 
A cool roof reflects and emits the sun's heat back to the sky instead of transferring it to the building below. Cool roofs reduce the cooling energy load, therefore reducing air pollution and greenhouse gas emissions. Cool roofs may last longer than traditional types and help mitigate the urban "heat island" effect. The net energy savings achieved from cool roofs varies depending on the climate because they can also reduce the heat load on a facility in colder climates, where summer energy rates have less overall influence on energy bills.

While it is true that cool roofs are mostly associated with white roofs, they come in a variety of colors and materials. Cool roof pigments allow metal roofing products to be ENERGY STAR® rated even in dark colors that aren't as reflective as whites or light colors, but can still save energy over other paints.

Benefits of cool roofs:
  • Energy savings and reduced air pollution/greenhouse gas emissions
  • Extended roof life over other construction materials
  • Improved comfort
  • Reduced degradation of roofing membranes on commercial facilities
  • Reduction in urban "heat island" effect

A list of various cool roof products is available on the Cool Roof Rating Council (CRRC) website.
