Why Roofing Is the Highest-Risk Trade for Insurance
Falls from heights are the single leading cause of death in the construction industry nationally — and roofers work at height on every single job. The combination of fall risk, fire hazard from torch-applied roofing systems, and the significant completed operations exposure from water intrusion claims makes roofing the trade that insurers rate most cautiously. Many standard carriers won't write roofing contractors at all, and those that do charge significantly higher premiums than for other trades.
This doesn't mean roofing contractors can't get good coverage. It means you need a broker who specializes in contractor insurance and has access to the specialty and non-admitted markets that write the roofing trade. At CaliContractorInsurance.com, we place roofing contractors regularly — including those who have been declined by standard carriers.
California adds additional complexity. The state's wildfire environment creates unique demand for roofing work (post-fire reconstruction) but also means that insurers in fire-prone areas have reduced appetite across all construction trades. We know which markets are open in California and which are not — saving you the time of applying to carriers that will simply decline.
CSLB License Classes for California Roofers
- C-39 — Roofing Contractor: The primary license for roofing work in California. Authorizes the installation, repair, and maintenance of all types of roofing systems including composition shingles, tile, flat/low-slope (TPO, EPDM, modified bitumen, built-up roofing), metal roofing, and waterproofing membranes.
- C-17 — Glazing: Required for the installation of skylights and other glazing units in roofing applications. Many roofing contractors encounter skylight installation requests — if you do this work, verify your licensing covers it.
Like all CSLB licensees, roofers must maintain a $25,000 contractor license bond. California also has specific regulations about roofing contractor advertising and disclosure requirements — the CSLB has taken enforcement action against unlicensed roofers, particularly after storm events.
Been Declined? If a standard carrier has declined to write your roofing business, don't assume you're uninsurable. We have access to specialty and non-admitted markets that specifically write roofing contractors — including those with prior claims or adverse loss history.

Key Insurance Coverages for Roofing Contractors
General Liability with Completed Operations
General liability insurance is the foundation, but for roofers the completed operations component is especially critical. Water intrusion claims from improper installation or flashing failures can surface months or years after the job is done. A homeowner who discovers ceiling staining and traces it to a roofing defect from a project completed 18 months ago has a valid completed operations claim. These claims are common and can be expensive — especially in California where interior finishes and construction costs are high.
Workers' Compensation
Roofing has one of the highest workers' comp rates of any trade — the premium reflects the genuine fall risk inherent to the work. California requires workers' comp for any employee. Roofers with strong safety programs, consistent use of fall arrest systems, and documented safety training can manage their X-mod over time. Your experience modifier has an outsized effect on WC costs in roofing because base rates are already high.
Commercial Auto
Roofing crews typically drive pickups and flatbeds loaded with materials to job sites daily. Commercial auto insurance covers your fleet and your employees who drive them. Be sure to include trailer coverage if you're hauling equipment or dumpsters — liability from trailer accidents is covered under your commercial auto policy, not your GL.
Real Claim Scenarios for California Roofing Contractors
Worker falls from two-story residential roof. A roofing laborer slipped on a wet tile roof surface and fell approximately 18 feet to a concrete driveway. The fall caused a traumatic brain injury, multiple fractures, and a prolonged hospitalization followed by rehabilitation. The workers' compensation claim covered all medical treatment, over a year of temporary total disability, and ultimately a large permanent disability settlement. This is precisely why roofing WC rates are so high — and why WC coverage is non-negotiable.
✓ Covered by Workers' CompensationTorch-applied roofing ignites attic fire. A roofing crew applying torch-down modified bitumen on a flat roof addition ignited dry wood blocking near the roofline. The fire spread into the attic space before it was detected, causing significant structural and finish damage. Torch work fires are among the most common and serious claims in the roofing industry — many carriers restrict or exclude torch work entirely, making it critical to disclose this work method on your application.
✓ Covered by General LiabilityImproper installation causes water damage three years later. A homeowner experienced recurring ceiling leaks that were initially attributed to storms. Three years after a roof replacement, a forensic roofing consultant determined that flashing at a chimney penetration had been improperly installed, allowing water infiltration that over time damaged the interior. The completed operations claim covered interior repairs, mold remediation, and temporary housing during remediation.

Roofing is unequivocally the most expensive trade to insure. Both GL and workers' comp rates for roofers significantly exceed other trades — reflecting the real claims history of the industry. Here are general benchmarks, though actual pricing varies considerably based on claims history, safety program, roof types, and use of torch equipment:
| Contractor Profile | Employees | Estimated GL Premium | Notes |
|---|---|---|---|
| Sole Proprietor Roofer | Owner only | $4,000 – $12,000/yr | Residential, no torch work |
| Small Roofing Crew | 2–5 workers | $12,000 – $35,000/yr | Residential and commercial; WC additional |
| Commercial Roofer | 10+ workers | $35,000 – $80,000+/yr | Commercial flat roofing, torch work, large volumes |
* Workers' comp for roofing is priced separately and is also among the highest-rated in construction. Total program costs can be substantial. We help roofers find the most competitive pricing available in the market.
How Your X-Mod Affects Roofing Workers' Comp Costs
The experience modification factor (X-mod) has an outsized impact on roofing WC costs because roofing base rates are already so high. A 0.85 X-mod vs. a 1.15 X-mod on a large roofing payroll can represent tens of thousands of dollars annually in premium difference. Building a lower X-mod takes time — typically 3 years of claims data — but the following practices directly influence it:
- Implementing and documenting a formal fall protection program that meets Cal/OSHA Title 8 requirements
- Requiring daily toolbox talks and documenting attendance
- Providing appropriate PPE and fall arrest systems and enforcing their use
- Reporting all injuries promptly and managing claims proactively with your WC carrier
- Using a return-to-work program to get injured workers back on modified duty as soon as medically appropriate — this significantly reduces claim costs
