Most Contractors Can't Offer This Warranty
Any roofer can install Owens Corning shingles. Only Platinum Preferred Contractors like Cornerstone can register the Platinum Protection Roofing System Limited Warranty, the highest and longest coverage Owens Corning offers. It backs both materials and labor for up to 50 years, comes straight from the manufacturer (not just us), and transfers to the next homeowner if you sell. Compare the coverage tiers below.
Warranty coverage subject to Owens Corning terms. Platinum Protection requires installation by a certified Owens Corning Platinum Preferred Contractor.
