What Vandalia Customers Say

★★★★★

"We got three quotes for a full tear-off and Dunnegan Roofing & Maintenance was the most thorough. They showed us the rotted decking in the photos before replacing it. New Timberline HDZ shingles look great."

— Daniel E., Vandalia

★★★★★

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

— Jennifer K., Vandalia
