In virtually every state, yes. Workers' compensation insurance is legally required for roofing contractors who have employees, and in many states the requirement kicks in with your very first hire. Only Texas and a small number of other states allow employers to opt out of the workers' comp system entirely, though even in Texas, opting out exposes you to direct employee lawsuits with no cap on damages, which is a risk most roofing companies cannot afford to take.
Workers' compensation covers medical expenses, lost wages, rehabilitation costs, and death benefits for employees who are injured or become ill as a result of their job. In roofing, the most common claims involve falls from heights, injuries from pneumatic nail guns, heat-related illness, strains and sprains from heavy lifting, and cuts from sheet metal and flashing. OSHA data consistently places roofing among the top five most dangerous occupations in the United States, with a fatal injury rate roughly six times higher than the national average for all industries.
The NCCI class code for roofing is 5551 (Roofing - All Kinds & Drivers). This is one of the highest-rated class codes in the workers' compensation system because of the frequency and severity of roofing injuries. Base rates vary by state but commonly fall between $10 and $30 per $100 of payroll. For a roofing company with $500,000 in annual payroll, that translates to workers' comp premiums ranging from $50,000 to $150,000 per year before any credits or debits are applied. This makes workers' comp the single largest insurance expense for most roofing operations.
Your experience modification rate (EMR or e-mod) is the primary lever you have to reduce your premium. The EMR compares your company's actual claims history to the expected claims for businesses of your size in your class code. An EMR of 1.00 means your claims experience is average. Below 1.00 means you are performing better than average and will receive a credit on your premium. Above 1.00 means your claims experience is worse than average and you will pay a surcharge. A roofing company with an EMR of 0.80 will pay 20% less than the base rate, while a company with an EMR of 1.30 will pay 30% more. Over three to five years, investing in safety programs, proper training, and claims management can move your EMR significantly and save tens of thousands of dollars annually.
Subcontractor management is a critical issue for workers' comp in roofing. If you hire subcontractors who do not carry their own workers' comp coverage, your insurer will include those subs' payroll in your premium calculation at audit time. This can result in a massive unexpected bill at the end of your policy term. Always require certificates of insurance from every sub showing active workers' comp coverage with limits that meet your state's requirements. Keep copies on file and verify them before each project.
Independent contractor misclassification is another common pitfall. If you classify workers as independent contractors to avoid paying workers' comp premiums, but those workers function as employees under your state's legal test, you face penalties including back premiums, fines, and potentially criminal charges. The IRS, state labor departments, and insurance auditors all scrutinize contractor classifications, and the consequences of getting it wrong are severe. Most states use some variation of the ABC test or common-law factors test to determine whether a worker is an employee or independent contractor.
If you are a sole proprietor or partner with no employees, most states allow you to exempt yourself from workers' comp requirements. However, many GCs and project owners will not let you on their job site without a workers' comp policy or a valid state-issued exemption certificate. Even if you are legally exempt, purchasing a policy for yourself provides income protection if you are injured on the job and keeps you eligible for the contracts that drive your revenue.
