• Blow-off protection: printed nail line guides installers to position and fasten the shingles correctly, to help keep them on the roof and prevent them from blowing off in high wind
• Built-in algae-resistance: we embed special algae-resistant granules into our shingles to help inhibit the growth of blue-green algae that can cause unattractive black stains, streaks and discoloration
• The only time it’s good to be tacky: our shingles have IKO FastLock™ sealant strips along their bottom edges. When activated by the sun’s heat, these strips get extra-tacky and create a strong bond to ensure maximum protection against wind uplift, blow-off and water penetration
• This shingle’s core strength is its fiberglass mat: our fiberglass mat is coated top and bottom with weathering asphalt, then surfaced with colored granules. It’s heavy-duty for exceptional durability and structural integrity
