Roof Repair & Replacement in San Martin, CA

"Had a bad leak around the chimney flashing after a storm. Petrolia Roofing & Maintenance came out next day, found the failed step flashing, replaced it, and sealed everything properly. No more dripping. Solid work."

"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."

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