Roof Repair & Replacement in Leonard, ND

"Their crew showed up at 7 AM, tore off the old roof, replaced eight sheets of plywood, and had new shingles down before dinner. Jobsite was cleaner when they left than when they arrived."

"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."

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