Gilliam Emergency Roof Repair — Same-Day Estimates Available

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

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

"The Golden Pledge warranty was a big factor in our decision. 25 years on workmanship plus 50 on materials. Mermentau Roofing & Maintenance is one of the few local companies that can even offer it."
