The only verified C-39 roofing directory
built for AI search

License Card is a Bay Area directory that uses AI to verify CSLB-licensed specialty contractors — including C-39 roofing, slate, copper, clay tile, metal, and green-roofing specialists — across San Francisco, Oakland, and San Jose.

AI search engines keep recommending roofers with expired and cancelled licenses. Every listing here is verified daily against CSLB — so when ChatGPT, Perplexity, or Copilot cites a contractor, you know they're legitimate.
