Manteca has seen explosive growth over the past decade — new neighborhoods going up alongside homes that have been through 20, 30, 40 Central Valley summers. Newer homes need roofs installed correctly from the start. Older homes need roofers who know what’s underneath and won’t miss what’s coming.
We’ve been working in this region since 1995. Whether your home is brand new or was built when Manteca was still mostly farmland, we know what the valley climate does to roofing materials and what it takes to make a roof last here long-term.
Video before we write a single number.
Every Manteca estimate starts with a documented roof inspection on camera. You see exactly what we found before you’re asked to commit to anything.

What Central Valley homeowners say about Grandmark.
“Called three roofers before Grandmark. Nobody else put my roof on camera before giving me a price. The video inspection alone told me they were the right choice before the quote even came in.”
“New roof, new ducts, and a full video of everything they did. I had no idea you could replace the ducts while the deck was open — Grandmark explained it and did it all in the same job. Incredible.”
“Storm took out part of my roof on a Friday. Grandmark was out Saturday, documented the damage, and had a crew working by Monday. The completion video they sent was more thorough than I expected.”
