What Winthrop Harbor Customers Say
"Our flat roof on the garage had been patched five times by other companies. Ottawa Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."
"We got three quotes for a full tear-off and Ottawa Roofing & Maintenance was the most thorough. They showed us the rotted decking in the photos before replacing it. New Timberline HDZ shingles look great."
"I called about a small leak and expected a hard sell on a full replacement. The inspector showed me it was just a cracked pipe boot — $300 repair instead of a $12,000 roof. Honest company."
