Professional Roofing Services in New Boston

"Our flat roof on the garage had been patched five times by other companies. Sullivan Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."

"Hail punched through half our shingles last spring. Sullivan Roofing & Maintenance handled the entire insurance claim — met the adjuster, filed the supplement, and we paid nothing out of pocket besides the deductible."

"Second roof Sullivan 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."

We've been installing and repairing roofs for over 22 years. That experience shows in how we handle complex roof lines, unexpected deck damage, and insurance claim disputes. We've seen everything and know how to handle it.

We don't charge for inspections and we don't pad estimates. If your New Boston roof needs a repair, we'll tell you. If it needs a replacement, we'll explain exactly why. No high-pressure sales, no scare tactics.
