The Roof Be Cool

A cool reflective roof stays 50 to 60 degrees cooler when exposed to the same summer heat.

The roof be cool.

By doing this cool roofs allow for a more comfortable and controlled indoor environment. A cool roof reflects most of the incident sunlight and emits some of the absorbed radiation back into the atmosphere instead of passing the heat on to the building below. Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. The surface of a cool roof reflects more sunlight and releases more heat than a so called hot or dark roof.

A cool roof prevents heat absorption by reflecting the sun s heat and then emitting its radiation back into the atmosphere. Up to 70 when paired with a colored reflective coating. Compared to the 30 solar reflectance of asphalt shingles that s a dramatic difference. The primary advantage of a cool roofing system is that business owners can expect to use less energy to cool their small businesses.

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 and save energy and money by using less air conditioning. In hot climates traditional roofs in the contiguous united states can reach temperatures of 150 to 185 degrees fahrenheit.
