Keith Roofing Company has been covering Santa Clara roofs for decades — residential and commercial, tile and shingle, repair and replacement. Family-owned since 1952. BBB A+ Accredited. California Licensed #1118418.
Santa Clara has been a steady service area for Keith Roofing since the 1960s. It's a city of roughly 130,000 with a mix of historic neighborhoods (particularly the Old Quad near Santa Clara University), 1950s–70s residential development (Forest Park, Mariani), and substantial commercial and institutional building stock supporting Silicon Valley (the area around Mission College, Great America, and the Levi's Stadium / 49ers campus).
Santa Clara has its own Building Division separate from San Jose, and its own active permit-review process. The residential work is mostly straightforward re-roof cycles; the commercial work includes substantial flat-roof replacement, coating, and repair for office parks, retail, and industrial properties. Volume and variety are what define our Santa Clara work. From Old Quad Craftsmans to Great America commercial flat-roofs, we handle the full range. Our long-standing relationships with several Santa Clara commercial property management firms and our deep familiarity with the Santa Clara Building Division make us the default roofer for many local businesses and homeowners.
What this means for you: When you call Keith Roofing for your Santa Clara home or business, you're not getting a generic quote from a roofer who works everywhere and specializes nowhere. You're getting contractors who know this specific market — the typical failure modes, the dominant roof systems, the permit process, the HOA and preservation rules, and the pricing that makes sense for your property type and neighborhood.
Decades of working this specific market means we know the common failure modes, the dominant roof systems, and what to look for at estimate.
Residential roofing is mostly architectural asphalt shingle on post-war ranch and tract homes, with pockets of concrete tile on Mediterranean-style homes. The Old Quad neighborhood near Santa Clara University has some historic residential with Craftsman and Victorian homes. Commercial work is significant — TPO, modified bitumen, roof coatings, and commercial flat-roof repairs for the office-park and industrial building stock. Santa Clara is also home to substantial solar retrofit demand — high residential solar adoption means we routinely coordinate re-roofs with existing panel arrays.
Many Santa Clara homes are on their second or third re-roof cycle — original 1950s–70s tract homes plus 1990s re-roofs now aging out.
Older Santa Clara homes often have inadequate ridge or soffit ventilation — we upgrade at re-roof to extend shingle lifespan.
Many aging Santa Clara commercial flat roofs are candidates for silicone coating rather than full replacement — significant cost savings with 10–20 year warranty extensions.
Santa Clara's high residential solar adoption means many re-roofs involve coordinating with existing solar arrays — panel removal, re-roof, and panel reinstall.
Santa Clara's residential roof inventory is predominantly 1950s–70s architectural shingle housing stock, now on its second or third re-roof cycle. The dominant material for these re-roofs is architectural asphalt shingle from CertainTeed, GAF, or Owens Corning — we're certified contractors for all three and can deliver enhanced warranty coverage that single-manufacturer roofers often can't match.
A typical Santa Clara residential re-roof follows a standard sequence: permit pull from Santa Clara Building Division, full tear-off of existing material, deck inspection and repair as needed, synthetic underlayment with 6-inch laps, ice/water shield in valleys and at penetrations, architectural shingle install with starter course and hip/ridge cap, and proper ventilation (ridge vent typically preferred over box vents). We document installation with photos at each phase for warranty registration and owner records.
On the commercial side, Santa Clara's office-park and industrial building stock has substantial aging BUR (built-up roof) inventory. Many of these roofs are candidates for silicone restoration coating rather than full replacement. Silicone coatings from GE, Gaco, and other manufacturers restore waterproof integrity at 30-40% of full-replacement cost and add 10-15 years of service life. For roofs past coating candidacy, we install TPO single-ply (Carlisle SynTec, GAF EverGuard, Firestone UltraPly) with fleece-backed mechanically-fastened or fully-adhered systems depending on building specifics.
Architectural shingle systems installed to manufacturer spec deliver 25-30 year service life (premium options like CertainTeed Presidential reach 40+ years). Commercial TPO and silicone coating systems both deliver 20-30 year warranted service life. Our volume in Santa Clara means we see actual performance data across decades of installations, and we can advise on which material-and-installer combinations hold up locally.
Roofing materials and installation techniques should reflect local climate realities — not generic specifications. Here's what Santa Clara's specific weather patterns mean for your roof.
Santa Clara summers are typical South Bay — 85-92°F highs with significant UV exposure. Dark-color shingles on south-facing slopes see elevated temperatures; we typically recommend cool-roof compliant materials and adequate attic ventilation.
Typical South Bay rainfall — 15-18 inches annually. Atmospheric-river events in December-March can deposit heavy rainfall quickly. Proper underlayment and flashing are essential.
Low wildfire risk — Santa Clara is not in WUI zones. Fog exposure is moderate. Algae-resistant shingles are worth specifying for north-facing slopes.
Santa Clara roofing priorities: Title 24 cool-roof compliance (strictly enforced by local permit office), solid flashing for winter storms, and material selection that balances performance with cost across a large inventory of similar-spec residential and commercial properties.
Historic residential near Santa Clara University — Craftsmans and Victorians.
Mid-century ranch homes, standard shingle re-roof work.
Newer planned community with townhomes, condos, and single-family.
1950s–60s tract homes with mixed roof systems.
Commercial flat-roof systems for office and retail.
Industrial and commercial flat-roof work.
Santa Clara Building Division permits require clear scope documentation — we prepare submission packages with material spec sheets, Title 24 compliance, and project timeline.
Residential re-roofs are straightforward — typical 2-4 day jobs with clear scope. Commercial projects require additional planning: property manager coordination, tenant notification, access restrictions, and often staged scheduling.
All residential shingle installations include proper underlayment, ice/water shield in valleys, starter course at eaves, manufacturer-compliant nailing, and ridge vent ventilation. Commercial TPO installations include fleece-backed mechanically-fastened or fully-adhered systems per building spec.
We complete final walk-through with the homeowner or property manager, provide warranty registration documentation, and schedule any warranty inspections required by manufacturer programs.
We're CertainTeed SureStart PLUS, GAF System Plus, and Owens Corning Preferred Contractor certified — meaning we can offer enhanced warranties (often 30-50 years) from all three manufacturers. Single-manufacturer roofers can't match this breadth.
Decades of Santa Clara work means we know what the Building Division inspectors prioritize and how to structure permit applications for smooth approval. Fewer delays, fewer inspection failures.
Santa Clara's commercial property management firms recommend us because we handle the non-roofing operational side well — tenant communication, access coordination, staged scheduling, clean billing.
Santa Clara's high solar adoption means many re-roofs require panel coordination. We work with local solar installers to sequence removal and reinstallation, avoiding warranty issues and minimizing project disruption.

A 1970 Forest Park home had a 27-year-old shingle roof plus a 12-year-old residential solar array. The homeowner needed the roof replaced but the solar array still had significant service life. We coordinated with the original solar installer (a Bay Area firm still in business) to remove the panels, complete a full tear-off and re-roof with GAF Timberline HDZ architectural shingles, install new flashing and mounting points designed for the solar reinstall, and schedule the panel reinstallation within a week of roof completion. The project included a 50-year GAF System Plus warranty on the new roof and zero lapse in solar generation. Homeowner saved approximately $3,500 by coordinating the work vs. handling roof and solar separately.
