Roof Repair & Replacement in Greenland, NH

"Their crew showed up at 7 AM, tore off the old roof, replaced eight sheets of plywood, and had new shingles down before dinner. Jobsite was cleaner when they left than when they arrived."

"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."

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