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