There’s a line between a good shingle and a great shingle.™
It’s the nailing line on your shingles. The difference between a good shingle and a great shingle is having SureNail® Technology. With SureNail® Technology, strength and durability are built into every Duration® Series shingle, thanks to the unique fabric strip in the nailing area. This unique shingle design provides outstanding gripping power.
ENERGY STAR® is for roofs, too. Like the energy-efficient appliances in your home, an ENERGY STAR rated shingle can help make your home more comfortable and energy-efficient. These “cool” shingles reflect solar energy because the granules on the shingle help bounce the sun’s rays decreasing the amount of heat transferred into 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. ENERGY STAR rated shingles are required to have an initial solar reflectance index of 0.25 and a 3-year aged solar reflectance of 0.15.
