Engineered for the best installation
Proprietary LayerLock® Technology mechanically fuses the common bond between overlapping layers of a shingle. The added strength at the common bond powers StrikeZone® — the industry’s widest nailing area. StrikeZone® features a smooth microgranule surface for an asphalt-to-asphalt bond. The StrikeZone® nailing area is so easy to hit that a roofer placed 999 out of 1,000 nails correctly in our test.¹
