Quick answer
Roofing is one of California's highest-risk trades, and C-39 roofers must carry workers' comp even with no employees. Rates per $100 of payroll (class code 5552) are among the steepest of any trade, so a low X-Mod and a clean claims history are the main ways to control cost.

Roofing is one of the highest-rated workers' comp classes in California, and many carriers won't even quote it. Falls, heat, and heavy tear-offs push premiums sky-high. We place California roofers — including the high-X-Mod and hard-to-place accounts other brokers turn away.
Who We Cover
From residential re-roofs and repairs to large commercial and industrial work, WPIS writes workers' comp for California roofing contractors of every size — shingle, tile, metal, TPO, and built-up, pitched and flat. Whether you run one crew in the Valley or several across the state, your coverage is built around how your operation actually runs.
Roofing carries one of the highest base rates of any class code in California because of fall exposure, and a single serious claim can push your Experience Modification (X-Mod) above 1.50 for years. On top of that, most standard carriers won't write roofing at all, which leaves you with few options and high prices. We work the specialty markets that actually want roofing risk, manage your X-Mod proactively, and make sure your payroll is split correctly so you're not overpaying on office and sales staff.
A California workers' compensation policy pays for work-related injuries regardless of fault. For a roofer that means medical care for falls, burns, heat illness, and lifting injuries; lost wages while a worker recovers; employer's liability if an injury leads to a lawsuit; and coverage that keeps you compliant with your CSLB C-39 license. Coverage is required for virtually every California roofer with employees — there is no payroll threshold.
Class Codes
Roofing payroll sits in one of the highest-rated codes in the state, so getting your classification split right is one of the biggest levers on your premium. These are common examples — we confirm the exact classification for your operation:
| Class Code | Operation | Hazard Profile | Notes |
|---|---|---|---|
| 5552 / 5553 | Roofing — All Kinds & Drivers | Very High | Dual wage, $33/hr threshold: 5552 (under) / 5553 (at-or-above); tear-off & install |
| 8742 | Outside Sales / Estimators | Low | Must be split out of 5552 |
| 8810 | Clerical / Office | Low | Keep office staff out of the field code |
Estimators, outside sales, and office staff should never sit in the 5552 roofing code. Misclassification here is the single most expensive mistake we see roofers make — we audit your split at every renewal.
We track open claims, push for timely closure, and verify the data WCIRB uses. For roofers, where one fall can spike your mod for three years, proactive management is everything.
A written fall-protection and heat-illness program isn't just Cal/OSHA compliance — carriers price it in. A documented safety program is often the difference between getting quoted and getting declined.
Any sub who can't show valid workers' comp gets added to YOUR payroll at audit — at roofing rates. We help you track sub certificates so you don't get hit with a surprise premium bill.
FAQ
Is workers' comp required for my roofing business in California?
Yes — and roofing is stricter than most. Any roofer with employees must carry it, and you need it to keep your CSLB C-39 license. Many sole-proprietor roofers carry it too, because GCs won't let them on a job without it.
Why is roofing workers' comp so expensive?
Roofing has one of the highest base rates in California because of fall exposure, and most standard carriers won't write it at all. Premium is rate × payroll × X-Mod, so correct classification, a managed X-Mod, and access to the right specialty markets are what bring it down — all of which we handle.
Can I get covered with a high X-Mod or prior claims?
Yes — this is exactly what we do. We work with carriers that specialize in tough roofing risks, including accounts that have been non-renewed or declined elsewhere.
What happens with my subcontractors?
If a sub can't provide a valid workers' comp certificate, their payroll gets added to yours at audit — at roofing rates. We help you collect and track sub certificates so you avoid a surprise bill.

Yes, and roofers have long been required to carry it. C-39 roofing contractors must maintain workers' comp even with no employees, and SB 216 confirms coverage for all licensed contractors. The CSLB can suspend a license for any lapse.
Roofing is one of the highest-risk classifications because of fall exposure, so the rate per $100 of payroll is among the steepest of any trade. A clean claims history and a low X-Mod are the main levers to control the cost.
Roofing falls under California class code 5552 (Roofing - all kinds), which covers installing, repairing, removing, and waterproofing all types of roofs. Crews paid at or above the state's dual-wage threshold instead fall under 5553. Because roofing rates are high, a misapplied code can trigger a large bill at audit, so correct classification is important.
Invest in fall-protection and safety programs, manage claims aggressively to limit severity, keep your X-Mod down, and use a broker who shops specialty roofing markets instead of defaulting to State Fund.
