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.

What Our Customers Say
We were very please with the service provided by Cornerstone. Ours was not a normal path to securing a roof, however it was completed perfectly. From shingles to skylights to spouting. Camen worked 15 months to make it happen. He leaves no detail unfinished. Thank you Camen, Jake and crew for the new roof! Definitely would recommend.
Thanks to everyone at Cornerstone Roofing for doing great work with our new shingles, fascia and gutters. The work was done professionally and fast. Camen administered the job from start to finish with immediate response and answered all of our concerns. Larry and Jane C
Camen and his team did a great job. Very prompt, clear communication and stayed slightly under the estimate! Will use again for future projects!
