Licensed Roofer Serving Dallas, WI

"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."

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

"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."
