Americans spend about $40 billion annually to air condition their homes & buildings - sixth of all electricity generated in this country.
There are several options for you to cool your roof. The quick & easy way is attic installation. A home with no insulation or poorly insulated roof will require more air conditioning in the summer and more heating in the winter, and if you have any dreams of actually inhabiting the attic of a house with a poorly insulated roof, forget about it.
Another way to cool your roof is adding cool roof coating onto an existing roof. Cool roof coatings are white or special reflective pigments that reflect sunlight. Coatings are like very thick paints that can protect the roof surface from ultra-violet (UV) light and chemical damage, and some offer water protection and restorative features. Products are available for most roof types.
Cool Roof Coating
If your roof shingles are old, then replace your shingles with cool shingles. Cool shingles are made in three layers – usually a layer each of fiberglass and asphalt to provide insulation and protection, followed by a topical layer of highly reflective granules that acts as a mirror. These granules are great at reflecting sunlight and prevent solar heat build-up on your roof. This means that hot or sunny days have considerably less impact on the temperature of a home and make it less expensive to keep cool during the summer.
Cool shingles are the most effective in warm climates with a lot of sunshine. To get a sense of their impact in your area, use this Department of Energy calculator to estimate your savings with cool shingles at www.roofcalc.com.
Another option for shingle replacement is cool metal roofing. Metal roofing can consist of a high percentage of recycled material and is 100% recyclable. It does not get as hot as asphalt, a common roofing material, and it reflects heat away from the building underneath in summertime. As reported by the Cool Metal Roofing Coalition and the Oak Ridge National Laboratory, installation of reflective metal roofing can save your home up to 40% in summer cooling energy costs while highly emissive metal roofs can reduce urban air temperatures by as much as 12 ° F.
These cool roof options mean less money out of your wallet, less dependence on energy resources and less general air pollution in your neighborhood and across the nation.
