Verified Reviews
"Got three quotes for a roof replacement. San Gregorio Roofing & Maintenance was the middle price but the only one who actually got on the roof and showed me photos. Everyone else just eyeballed it from the driveway."
"Asked for a second opinion because another company said I needed a full replacement. San Gregorio Roofing & Maintenance said I only needed valley flashing repair and some shingle replacement. Saved me about $14,000. I trust these guys."
"Our roof was 22 years old and starting to curl. They did a full tear-off and installed Timberline HDZ in Weathered Wood. Looks incredible. Crew was fast and cleaned up everything."
