Insulating the Attic and Cool Roof Technology
The sun tends to heat conventional roof shingles up to temperatures as high as 140 or 150 degrees F during the summer. That heat is then radiated to the attic, which reaches scorching temperatures, usually 40 to 50 degrees hotter than the outside air. The heat in the attic then radiates through the ceiling into the living areas making your whole house uncomfortable. To make matters worse, some homes have air conditioner ducts running through the attic. Picture this: you pay for the electricity to run your air conditioner to cool the air down to 50 degrees, and then run the cold air through metallic ducts in the attic, that are baking at 150 degrees. Your air conditioner will have to work much harder to keep up, and your cooling bills will be extremely high, especially if you live in warmer areas of the U.S.
