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.
