Save Energy with a Cool Roof
Reflective roofing improves comfort and reduces cooling costs in the Deep South and anywhere the sun shines.
Synopsis: For homeowners in heating climates, a cool roof can be a good energy-saving option. Architect Linda Reeder outlines the reasons to consider a cool roof — largely, to save on cooling costs — and describes the way cool roofs work. Tile, metal, and asphalt all can be good cool-roof materials. Cool roofs aren’t foolproof; they can be prone to mold growth in hot, humid climates. Also, they may cost a little more than a traditional roof, depending on the roofing material you choose.
High-reflectance roofing, often called “cool roofing,” started appearing on homes more than 10 years ago, and its use has climbed steadily ever since. The reasons are simple: Cool roofing can reduce cooling costs up to 15%, it can lower oppressive summertime temperatures in cities, and because it doesn’t get as hot, it often lasts longer than traditional roofing does.
