Storm Damage? Free Roof Inspection in Derry — Call Now

"We got three quotes for a full tear-off and Thornton Roofing & Maintenance was the most thorough. They showed us the rotted decking in the photos before replacing it. New Timberline HDZ shingles look great."

"I called about a small leak and expected a hard sell on a full replacement. The inspector showed me it was just a cracked pipe boot — $300 repair instead of a $12,000 roof. Honest company."

"They replaced all our gutters along with the roof. Seamless aluminum, properly pitched. Water actually drains into the downspouts now instead of overflowing at every seam. Night and day difference."
