Home of the 50-Year Asphalt Roof Warranty

At Grant Roofs Ohio, we believe your roof should last a lifetime, so that’s exactly how we back it.

We’re proud to offer one of the strongest residential roofing warranties in the industry, thanks to our partnership with Owens Corning, the top name in roofing materials. As an Owens Corning Preferred Contractor, we install only Owens Corning products and deliver a level of quality that allows us to include the Preferred Protection System Limited Warranty at absolutely no extra cost to you.

What Makes This Warranty So Special?

This isn’t your typical “limited” warranty with lots of fine print and hidden loopholes. Here’s what you’re really getting:


Up to 50 Years of Material & Labor Coverage


10 Years of Workmanship Coverage

Even the best materials can fail if installed poorly, but not with Grant Roofs Ohio. And if something does go wrong due to workmanship?


One-Time Transferable

Thinking of selling someday?


Why This Matters

When you invest in a roof from Grant Roofs Ohio, you’re not just getting shingles. You’re getting a Total Protection Roofing System®—a layered, engineered system designed for durability, ventilation, and weather defense.

We install:

…and we do it all with Owens Corning certified products and techniques, because your roof is only as good as the system that holds it together.


Bottom Line?

No one beats this warranty.

We believe in doing the job right the first time—and standing behind it long after the crew leaves your driveway.

So whether you’re in your forever home or planning to sell in the next few years, this warranty gives you confidence, value, and peace of mind that lasts.
