Griswold Roofing Contractor | Serving Griswold From Onawa

"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."

"What sold me was the inspection report. Detailed photos of every damaged area, measurements, written explanation of what needed repair versus replacement. No other company gave us anything close to that level of documentation."

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

No Subcontractors

Every Griswold roof is installed by our own trained crews, not subcontractors pulled from a labor pool. That means consistent quality, accountability, and a crew that knows our standards from the first nail to the last drip edge.
