Cool Roof – Prescriptive

Cool roofs are roofing products that reflect more of the sun’s rays than standard roofing products. According to Energy Star, Energy Star qualified roof products can lower roof surface temperatures by up to 100 degrees. This reduces the amount of heat transferred inside the building and reduces the amount of air conditioning needed, including a possible 10-15% reduction in air conditioning for the hottest hours of the day.

According to Energy Savers, standard or dark roofs can reach temperatures of 150°F or more in the summer sun. A cool roof under the same conditions could stay more than 50°F cooler. Decreasing the roof operating temperature may also extend the life of the roof.

Cool roofs are generally considered most effective in areas with longer periods of warm weather that require significant usage of air-conditioners and other cooling methods.

Savings Through the Roof.

 

Cool Roofs reflect more sunlight and absorb less heat than traditional roofs. These effects reduce the amount of heat that gets transferred inside your house, reducing the amount of air-conditioning needed. Homeowners can see a 10-15% reduction in air-conditioning use during the hottest hours of the day.

 

HERO Pro Tip: If you have an attic, you can also get a Radiant Barrier installed on the inside of the roof to deflect even more heat.
