What Dunbarton Customers Say
"Had a bad leak around the chimney flashing after a storm. Alton Roofing & Maintenance came out next day, found the failed step flashing, replaced it, and sealed everything properly. No more dripping. Solid work."
"Our flat roof on the garage had been patched five times by other companies. Alton Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."
