Roof
Most of the roofs in the United States today are dark-colored. However, dark roofs absorb more energy from the sun and contribute to attic and home heat. Ultimately, the hotter it is in your attic, the harder your air conditioning will have to work in the summer and the higher your electric bills. Creating an energy efficient roof system for your home can combat these effects. An energy efficient roof should reflect a high percentage of solar energy and radiate away energy (heat) after it is absorbed.
Roof Coatings
One way to increase the solar reflectance and thermal emittance of your existing roof is to use a roof coating. Current Energy offers Hy-Tech roof coatings, which are fluid applied, ceramic filled coatings that are painted on top of your existing roof. A coated roof reflects and emits about 90% of the heat producing Infra Red radiation striking it. Hy-Tech coatings adhere well over aged galvanized and metal roofs, wood, shingle roofs, built-up roofs with dried-out asphalt or aluminum coatings, urethane and polystyrene foam insulation, polyester plastic panels, precast flat concrete, flat and barrel cement tiles and many single ply roofing materials.

Radiant Barriers
Tip: Don’t forget to install a radiant barrier right into the roofing material when building a new home or replacing a roof.
If you are putting a new roof on your home, you can use plywood with a radiant barrier already incorporated. Current Energy recommends Polar Ply radiant barrier sheathing, which is composed of an aluminum radiant barrier that blocks 97% of summer radiant heat. Polar Ply is laminated with flame resistant adhesive to the roof sheathing. Direct lamination provides durability, requires no additional construction labor, and substantially reduces the flammability of the roof sheathing.
