Why homeowners in Stanislaus County call Grandmark.
We find the real problem — on camera.
Every estimate starts with a video inspection of your roof. You see exactly what we found before we write a single number. No guessing, no inflated quotes.
Our crew, not a subcontractor.
The same licensed team that quotes your job is the team that shows up and completes it. 29 years. No strangers on your roof.
Proof delivered when the job is done.
Post-job completion video sent directly to you. Every seal, every penetration, every piece of material — documented. A permanent record you keep.
Ready to get your roof looked at?
One call. A licensed roofer comes out, documents your roof on camera, and gives you a straight answer on what it’ll cost.
