Your Local Roofer
in Claremont
Claremont is a college town with a charming historic district and a mix of Craftsman bungalows, Spanish Revival homes, and mid-century properties. Older homes especially benefit from a thorough roof inspection before minor issues become major repairs.
For Claremont 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 Claremont, it's one of our go-to options.
