Licensed Roofer Serving Peterborough, NH

"Emergency tarping after a windstorm ripped our ridge cap off. Gilsum Roofing & Maintenance had a crew out within three hours and tarped the exposed section before rain moved in. Saved us from interior water damage."

"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."

"Second roof Gilsum Roofing & Maintenance has done for us. First one on our primary home, now our rental property. Same crew both times, same attention to detail. Drip edge, ice shield, everything by the book."
