About

Cornerstone Construction & Roofing operates out of Garden Grove, CA, holding contractor license number 1092069 and serving commercial property owners across the greater Orange County metro. The company addresses both flat and low-slope roofing systems — the dominant roof types found on the retail strips, mixed-use developments, multifamily complexes, and light industrial buildings that define this corridor of Southern California. For facility managers evaluating roofing contractors in the Garden Grove area, Cornerstone brings a combined roofing and solar capability under one license, which can reduce coordination overhead when a roof replacement and PV system installation need to happen concurrently. Commercial flat roofing in this climate demands systems that resist UV degradation, thermal cycling, and periodic heavy rain events; proven options in this market include TPO membranes, EPDM, modified bitumen, built-up roofing, spray polyurethane foam, and reflective coatings — all relevant to the low-slope commercial stock common to Garden Grove's retail centers, office parks, and warehouse districts. The office is located at 10141 Westminster Ave, Unit 201, Garden Grove, CA 92843, and the team is reachable by phone at 714-206-4320 or by email at cornerstone@ccrsp.net. Standard business hours run Monday through Friday, 8 a.m. to 5 p.m., with limited Saturday availability. Facility managers should contact the team directly to discuss scope, scheduling, and whether service agreement structures are available for ongoing preventive maintenance or post-installation inspections.
