Quick Answer
WCIRB Class 5551 — Roofing covers California contractors installing, repairing, or replacing roofs. It carries some of the highest WC rates in the state: pricing varies by classification, payroll, operations, claims history, limits, and underwriting per $100 of payroll depending on residential vs commercial mix and carrier. The high rates reflect fall-injury frequency and severity. Call (858) 925-9555 — we shop specialty roofing carriers.
What Class 5551 Includes
- Residential roofing (highest end of the rate range)
- Commercial flat and low-slope roofing (slightly lower)
- Roof tear-off and replacement
- Roof repair
- Skylight and roof penetration work integrated with roofing
What's NOT in 5551
- Solar installation only (often Class 7228 or 5190)
- Structural roof framing (Class 5645 — carpentry)
- Roof access for HVAC equipment placement (different classes)
Why Rates Are So High
- Falls are the leading cause of construction fatalities in California
- Even non-fatal falls cause long-term lost-time claims
- Reserves stay open for years, hurting X-Mods
How to Lower Your 5551 Rate
- Lower your X-Mod (clean claims, fast claim closure)
- Document a written fall-protection safety program (5–15% credit available)
- Separate clerical payroll into Class 8810
- Consider an officer exclusion if eligible
- Shop specialty roofing carriers — many standard markets decline roofing
