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