Our Energy Roofing System

Cool Roofs can reduce the roof surface temperature by many degrees Fahrenheit, thereby reducing the heat transferred into the building below. This helps to reduce energy costs (by keeping attics and ducts cooler), improve occupant comfort, cut maintenance costs, increase the life cycle of the roof, and reduce urban heat islands along with associated smog.
Energy StaR® is for roofs to.

Similar to the energy-efficient appliances in your home, roofing products can provide energy-saving qualities. Owens corning Duration Premium
Cool roofing shingles can help reduce your energy bills when installed properly. These shingles reflect solar energy, decreasing the amount of heat transferred to a home’s interior—and the amount of air conditioning needed to keep it comfortable. Actual savings will vary based on geographic location and individual building characteristics.
