What is a Cool Roof?

A cool roof is a roofing system that can deliver high solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the building) and high thermal emittance (the ability to radiate absorbed, or non-reflected solar energy) is a cool roof. While most cool roofs are white or other light colors there are cool color technologies that come in a variety of colors and still maintain high solar reflectance.

The roof stays cooler and reduces the amount of hear transferred to the structure below. This helps to keep the building cool and at a more consistent temperature.

The two basic characteristics that determine the ‘coolness’ of a roof are solar reflectance (SR) and thermal emittance (TE). Both properties are rated on a scale from 0 to 1, where 1 is the most reflective or emissive.

Aesthetics – a roof that performs and looks good

A cool roof can significantly reduce your cooling energy costs and increase your comfort level by reducing temperature fluctuations inside your building.  Average energy savings range from 7%-15% of total cooling costs.

When people think about making their buildings more “green” or sustainable, cool roofing isn’t always the obvious choice.  However, certain green building programs, such as the U.S. Green Building Council’s LEED, give credit for installing a cool roof.  So if you are trying to save energy or make your building more environmentally-friendly, a cool roof is one way to achieve that goal.
