About

Cornerstone Roofing Inc. holds a 5.0 Google rating across verified reviews — a rare mark of consistency that facility managers and property owners in Santa Rosa, CA can rely on when evaluating commercial roofing partners. Licensed under CA Lic. #909400 and fully bonded, Cornerstone serves Sonoma County commercial and residential clients with a scope that includes low-slope and flat roofing systems alongside shingle, metal, and tile applications. For facility managers overseeing retail strips, office buildings, multifamily complexes, or mixed-use properties in the Santa Rosa metro, Cornerstone's flat and low-slope capabilities translate to practical experience with modified bitumen, TPO, EPDM, and protective coatings — the systems most commonly specified on commercial structures throughout Northern California. The contractor's responsiveness is a recurring theme in client feedback: the team has demonstrated a pattern of accelerating project timelines ahead of incoming storms, a critical capability for property managers who cannot afford interior damage or tenant disruption from delayed roof replacements. Work spans from targeted leak repairs and roof inspections to full system replacements on multi-story structures, making Cornerstone a viable single-source vendor for smaller commercial portfolios across Sonoma County. Their second-generation, family-operated structure keeps decision-making lean, which typically means faster estimates, clearer communication, and accountability that larger regional contractors sometimes struggle to match. Operating Monday through Friday out of their Santa Rosa headquarters on Llano Road, Cornerstone is positioned to respond efficiently to commercial accounts across the greater Santa Rosa area, including Roseland, Southwest Santa Rosa, and the Wright corridor. Facility managers seeking a licensed, proven flat-roof contractor in Sonoma County will find Cornerstone Roofing a credible option for both reactive repairs and planned capital replacements.
