Expert Verdict — Reviewed by the SuperArbor Pro Desk
Order three bundles per square plus waste of roughly 10-15% for cuts, valleys and hips, and use IKO starter and hip-and-ridge pieces from the same line for a complete system. Cool Colors shingles suit projects targeting solar reflectance; verify the printed reflectance values if the project requires them. Fasten per IKO's nailing pattern to maintain the 110 MPH wind rating.
Install shingles per the manufacturer's application instructions and local building code, using roof anchorage and fall protection when working at height.
Order IKO Cambridge Cool Colors Harvard Slate Cool Plus shingles by the bundle for your next roof.
