What Rochester Customers Say

★★★★★

"Second roof Thornton Roofing & Maintenance has done for us. First one on our primary home, now our rental property. Same crew both times, same attention to detail. Drip edge, ice shield, everything by the book."

— Karen S., Rochester

★★★★★

"The Golden Pledge warranty was a big factor in our decision. 25 years on workmanship plus 50 on materials. Thornton Roofing & Maintenance is one of the few local companies that can even offer it."

16+ Years of Experience

Hail, wind, and monsoon damage are common in NH. Our team includes HAAG Certified inspectors who document damage the way adjusters expect it. We handle the entire insurance claim process so you don't have to.

Rochester Roofing FAQ

Yes. Thornton Roofing & Maintenance is fully licensed, bonded, and insured for roofing work across NH. We pull all required permits for Rochester projects and schedule inspections with the local building department.

Most residential roofs are completed in a single day. We stage materials the day before and our crew arrives at 7 AM. Larger homes, steep pitches, or multi-layer tear-offs may take two days. We never leave a roof uncovered overnight.

Often, yes. Not every roof problem requires a full replacement. If the damage is isolated (a few missing shingles, a flashing leak, a small area of hail damage), a repair may be the right call. We'll inspect and give you an honest recommendation.
