What a cool roof can do for your home or building

Cool roof projects use less energy, are cooler and more pleasant for occupants.

  • For every 5% of added reflectivity, a roof is approximately 4 degrees F cooler in direct overhead summertime sunlight.
  • Studies show that cool roofing can lower energy demand in buildings.
  • Cool roofs should last longer, because their cooler surfaces are less subject to chemical and atmospheric degradation.
  • According to the Federal Energy Policy Act of 2005, eligible contractors who construct energy efficient homes may qualify for a $2,000 tax credit starting in 2006, and homeowners may qualify for a $500 tax credit. Cool metal roofing is specifically referenced for these credits in Sections 1332 and 1333.
  • Rebates for cool roofs and other energy-savings products may be available through many local and state governments and utilities.

What a cool roof can do for the environment…

Products that earn the ENERGY STAR can help prevent greenhouse gas emissions by meeting strict energy efficiency guidelines set by the U.S. Environmental Protection Agency and the U.S. Department of Energy.

  • Cool roofing helps reduce ozone and smog by lowering peak summer temperatures in metropolitan areas. (For every 1o F rise in air temperature, smog increases 3%.)
  • Studies have shown that the widespread use of cool roofing could potentially save $21 billion in direct energy usage costs and peak demand charges.
  • Cool roofs reduce landfill usage because they can often be applied directly over existing roofs, eliminating the need for tear-off.
