When your roofing company works across state lines, workers compensation becomes significantly more complex. Each state has its own workers comp laws, rates, and regulatory requirements. Working in a state where you do not have proper coverage can result in fines, stop-work orders, and denial of claims for injured employees. If you are expanding your service territory or chasing storm work across state lines, understanding multi-state workers comp is critical.
The "Other States" Endorsement
Every workers comp policy includes an "other states" section on the Information Page (formerly the declarations page). Item 3.A lists the states where you have active operations and payroll. Item 3.C — the "other states" or "all states" endorsement — lists additional states where your policy will provide coverage if you begin work there. If a state is not listed in either 3.A or 3.C, your policy does not cover injuries that occur in that state.
Before you send a crew to a new state, verify that state appears on your other states endorsement. If it does not, contact your broker to add it — ideally 30 days before work begins. Adding a state mid-term typically does not increase your premium until the audit captures actual payroll worked in that state.
Monopolistic State Funds
Four states operate monopolistic or exclusive state funds for workers compensation: Ohio, Wyoming, Washington, and North Dakota. In these states, you cannot use your private workers comp policy. You must purchase coverage directly from the state fund. If you are a Texas roofing contractor sending a crew to Ohio for a commercial project, your Acuity or Travelers workers comp policy will not cover injuries there. You need a separate Ohio Bureau of Workers Compensation policy, which requires registration, premium deposits, and compliance with state-specific reporting.
The application process for monopolistic state funds takes two to six weeks, so plan well ahead of any project start dates. Penalties for working in these states without state fund coverage include fines of $1,000 per day in Ohio and criminal misdemeanor charges in Washington.
Rate Differences by State
Workers comp rates for roofing (NCCI class 5551) vary dramatically by state. As of current rate filings, base rates range from approximately $14 per $100 of payroll in some Midwestern states to over $40 per $100 in states like California and New York. If you are based in a low-rate state and send crews to a high-rate state, your premium for those workers will be calculated at the destination state's rate, not your home state rate. A crew earning $200,000 in payroll on a three-month project in a high-rate state can generate $50,000 to $80,000 in additional workers comp premium.
Reciprocity Agreements
Some states have reciprocity agreements that allow your home state policy to cover temporary work in another state without requiring separate registration. These agreements vary and change periodically. Your broker should verify current reciprocity status before each out-of-state project. Even with reciprocity, the destination state's benefit levels typically apply to claims, which means your carrier pays benefits at the higher rate if the destination state mandates richer benefits.
Contractor Licensing and Insurance Proof
Most states require roofing contractors to hold a state-specific contractor's license, and the license application requires proof of workers comp coverage in that state. If you are pulling permits in a new state, you will need to show a workers comp certificate listing that state in Item 3.A. Some states — including Florida, California, and Louisiana — impose severe penalties on unlicensed contractors, including criminal charges and forfeiture of contract payments.
Practical Steps for Multi-State Roofing
Maintain a broad other-states endorsement covering every state where you might work. Track payroll by state meticulously — your auditor will need it. Budget for rate differentials when estimating out-of-state projects. Register with monopolistic state funds well before project start dates. And coordinate with your broker on compliance requirements in each new state before you mobilize crews.
