Dynasty, Asphalt Shingle, Cornerstone

Dynasty, Asphalt Shingle, Cornerstone • IKO Dynasty shingles with ArmourZone are manufactured in IKO’s special “Advantage” size. Bigger than most competitors’ comparable products, they offer greater exposure to give you a dramatic-looking roof that really stands out from the ordinary. • What’s an “ArmourZone”? It’s a 1 ¼-inch-wide nailing surface for correct nail placement reinforced by a tear-resistant band that provides even more fastening strength over a wider surface area of the shingle. Nails applied in this area are optimally positioned to help resist nail pull-through and shingle blow-off, even in high winds.
