Roof Repair & Replacement in Barnstead, NH

"The Golden Pledge warranty was a big factor in our decision. 25 years on workmanship plus 50 on materials. Gilsum Roofing & Maintenance is one of the few local companies that can even offer it."

"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. Gilsum Roofing & Maintenance handled the entire insurance claim — met the adjuster, filed the supplement, and we paid nothing out of pocket besides the deductible."
