What Portsmouth Customers Say
"Hail punched through half our shingles last spring. Onslow Roofing & Maintenance handled the entire insurance claim — met the adjuster, filed the supplement, and we paid nothing out of pocket besides the deductible."
"Emergency tarping after a windstorm ripped our ridge cap off. Onslow Roofing & Maintenance had a crew out within three hours and tarped the exposed section before rain moved in. Saved us from interior water damage."
"Our flat roof on the garage had been patched five times by other companies. Onslow Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."
