Free Upgrade from IKO Cambridge Architectural Shingles to IKO Dynasty Performance Shingles. Dynasty offers a wider 1-1/4” nailing zone with woven band on the back to ensure proper installation and minimize chance of shingle blow off from nail pull through. Achieve better wind rating with fewer nails, saving time and money! Deeper shadow bands create more definition in the roof color. Heavier weight helps shingles lay flatter, seal better and help prevent blow off.
