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

  1. Lower your X-Mod (clean claims, fast claim closure)
  2. Document a written fall-protection safety program (5–15% credit available)
  3. Separate clerical payroll into Class 8810
  4. Consider an officer exclusion if eligible
  5. Shop specialty roofing carriers — many standard markets decline roofing
