For San Dimas homeowners going with a shingle roof: Owens Corning manufactures shingles out of a plant in Compton, CA — right in Los Angeles County. That means shorter supply chain, faster material availability, and you're supporting a product made locally. Owens Corning is one of the most widely specified shingle brands in the country, and their Duration and TruDefinition lines carry a strong warranty. When we install shingles in San Dimas, it's one of our go-to options.
We're a family-owned C39 licensed roofing contractor based in Rancho Cucamonga. Our team handles every estimate and project-manages every job from start to finish. You always have a direct line to us with any 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.
