The practical case
More capacity per inch of width, a flat back that fastens tight to the fascia, and a decorative front edge that reads a little like crown moulding from the ground. It is the default for good reasons.
What’s covered
Ten years on our labor, and a 50-year limited — lifetime for the original homeowner — warranty on the shingle itself, backed by Owens Corning.
Full limited-warranty documentation is provided with every contract and governs in all cases.
