Roof Repair & Replacement in Dublin, NH

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

"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."

"We went with the Owens Corning Duration shingles in Driftwood. The ridge vent and intake ventilation they installed dropped our attic temperature noticeably. Energy bill went down that first summer."
