Licensed Roofer Serving Avoca, IA

"Our flat roof on the garage had been patched five times by other companies. Diagonal Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."

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

"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."
