Your Local Roofer
in Ontario
Ontario's housing stock ranges from older ranch-style homes near downtown to newer developments off Haven and Milliken. GAX Roofing has worked across the city — from tile roofs in established neighborhoods to shingle replacements in newer subdivisions. We handle Ontario city permits and inspections directly.
We're a family-owned C39 licensed roofing contractor based in Rancho Cucamonga. Arthur handles every estimate personally and project-manages every job from start to finish. He's the one you call if you have a question — before, during, or after the work is done. Free in-home estimates. There's a pitch — but we're not going to sit at your house for three hours and grind you down.
