Quick Answer
The C-39 Roofing Contractor classification is one of the most regulated in California. Required: active CSLB license, workers' comp regardless of employee count (C-39 was always required, even before SB 216), $25K license bond, and General Liability — most GCs require $1M/$2M minimum. WC Class 5551 runs pricing varies by classification, payroll, operations, claims history, limits, and underwriting per $100 payroll. Total annual insurance for a small roofing crew can hit $30K–$60K.
