The Roof Be Cool

The primary advantage of a cool roofing system is that business owners can expect to use less energy to cool their small businesses.

The roof be cool.

By doing this cool roofs allow for a more comfortable and controlled indoor environment. Cool metal roofing is a popular cool roofing material as it can offer more than twice the solar reflectance of traditional asphalt roofing. Up to 70 when paired with a colored reflective coating. Compared to the 30 solar reflectance of asphalt shingles that s a dramatic difference.

A cool roof prevents heat absorption by reflecting the sun s heat and then emitting its radiation back into the atmosphere. Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning. 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.

The surface of a cool roof reflects more sunlight and releases more heat than a so called hot or dark roof. As a result the roof stays cooler maintains a lower surface temperature keeping the building below at a cooler and more constant temperature. Standard or dark roofs can reach temperatures of 150 f or more in the summer sun.
