About

Diamond Roofing holds California Contractor License #995107 and operates out of El Cajon, CA, serving commercial and residential clients throughout San Diego County. For facility managers and property managers overseeing low-slope or flat-roof assets in the region, Diamond Roofing offers TPO cool roof systems as a primary commercial flat-roof solution — a cost-effective, reflective membrane well-suited to San Diego's high-UV climate. Beyond TPO, their commercial scope in the El Cajon and greater San Diego market typically encompasses EPDM, modified bitumen, built-up roofing (BUR), and protective coatings for existing roof assemblies, giving property teams options across the full flat and low-slope spectrum. Shingle systems round out their portfolio for multifamily and mixed-use assets where sloped sections require attention alongside flat field areas. The contractor is licensed and insured, which satisfies a baseline requirement for most commercial procurement processes and certificate-of-insurance requests. Diamond Roofing operates Monday through Friday, 7:00 AM to 4:00 PM, with Saturday appointments available, and can be reached at 619-295-3110 or admin@diamondroofingsd.com for inspection scheduling. While the company's messaging leans heavily residential in tone, their stated scope includes commercial roofing work across San Diego County — making them a viable candidate for smaller commercial accounts, neighborhood retail centers, multifamily communities, and light industrial or office properties in the El Cajon corridor. Facility managers evaluating this contractor should request explicit commercial project references, clarify whether preventive maintenance agreements are available, and confirm crew capacity for multi-building or portfolio-level engagements before award.
