Greenland Roofing & Maintenance | Gilmanton Roofing Services

"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."

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

"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."

Storm Damage Specialists

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.

GAF Master Elite Certified

Only 2% of roofing contractors in the country hold GAF Master Elite certification. That gives Gilmanton homeowners access to the Golden Pledge warranty: 25 years on workmanship, 50 years on materials. It's the strongest warranty in the industry.

Manufacturer-Certified Installation

We hold certifications from GAF, Owens Corning, and CertainTeed. That means the manufacturers have trained and vetted our crews and will back our installations with their strongest warranties. Your Gilmanton roof gets factory-level quality control.
