Grandmark Service Company was founded on a belief that California homeowners deserve honest work, lasting solutions, and proof that the job was done right. Two brothers launched the company in Fresno, CA, starting with Grandmark Roofing. What began as a roofing company grew into a coordinated team handling roofing, HVAC, and solar. The approach treats the roof, air, and comfort as one interconnected system. Ducts are replaced through the open roof, every penetration is sealed by a roofer, and video documentation is provided on every single job.

Financing options include 0% for 18 months.
