Title 24 now requires the use of cool roofing materials materials with an initial solar reflectance of 0 70 or greater and an initial thermal emittance of 0 75 or greater measures on a scale of 0 to 1 with one as the highest rating on all low slope non residential roofs over conditioned spaces heated or cooled. As the term implies the temperature of a cool roof is lower on hot sunny days than a conventional roof reducing cooling loads and the energy required to provide air conditioning.
