What San Mateo 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. Port Costa Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."
