Cool Roofing Not Specific to a Single System

Ask any expert to define "cool roof", and his or her explanation will likely include the words “reflectivity” and “emissivity.”

What is a Cool Roof?
Any roof that can boast strong performance in those two areas (the ability to reflect sunlight off a facility’s rooftop while minimizing roof temperature) is a good candidate for the designation of "cool roof".

A cool roof is any 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), helping to improve the energy efficiency of the building and mitigating the urban heat island effect.  Most cool roofs are white or other light colors.

The term cool roof can also refer to a geo engineering technique to address global warming through solar radiation management, provided that the materials used not only reflect solar energy, but also emit infra-red radiation (thereby cooling the planet).

Cool Roof Options
The sky is the limit when it comes to choices of systems that qualify as a cool roof - the idea that opting for a "cool roof" limits you to a specific type of product is a common misunderstanding. You can get a cool roof in almost any material you might be considering. For example, Conklin offers cool roofing solutions for fabric reinforced, metal, foam, EPDM, and single-ply systems.

For more information on cool roofing options, please contact a professional roofing contractor in your area that specializes in cool roofing.
