A cool roof is designed to reflect more sunlight and absorb less heat than a standard roof. Cool roofs can be achieved by coloring, highly reflective materials or coverings. Nearly any types of buildings can benefit from a cool roof but consider the climate and other factors before deciding to install one. Standard or dark roofs can reach temperatures of 150™F or more in the hot summer sun. A cool roof under the same conditions could stay more than 50™F cooler saving energy and money by using less air conditioning.
