Diablo Roofing Contractor | Serving Diablo From Hickman

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

"Had a bad leak around the chimney flashing after a storm. Hickman Roofing & Maintenance came out next day, found the failed step flashing, replaced it, and sealed everything properly. No more dripping. Solid work."

"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."
