The per-employee cost of roofing insurance depends on several variables, but for workers' compensation alone, you should budget between $5,000 and $20,000 per employee per year based on typical roofing wages and NCCI class code 5551 rates. When you layer in the employer's share of general liability, auto, and umbrella coverage, the total insurance cost per roofing employee commonly ranges from $7,000 to $25,000 annually. Understanding how these costs break down helps you price your bids accurately and avoid underbidding jobs that will erode your margins.
Workers' compensation is calculated as a function of payroll, not headcount, so the per-employee cost varies directly with each employee's wages. Under NCCI class code 5551, manual rates typically range from $10 to $30 per $100 of payroll depending on your state. If a roofing laborer earns $40,000 per year and your state's rate is $15 per $100, the workers' comp cost for that employee is approximately $6,000 per year before your EMR adjustment. For a crew lead earning $55,000 in the same state, the cost would be approximately $8,250. In a high-rate state like New York or California with rates closer to $25 per $100, those figures jump to $10,000 and $13,750 respectively.
Your experience modification rate multiplies across every employee's payroll. If your EMR is 0.85, you would pay 15% less than the manual rate for each employee. If your EMR is 1.20, you pay 20% more. For a 10-person roofing crew with combined payroll of $450,000 in a state with a $15 rate, the difference between a 0.85 EMR and a 1.20 EMR is approximately $23,625 per year ($57,375 vs. $81,000). Spread across 10 employees, that is a difference of $2,362 per person per year, which illustrates why safety programs and claims management have such a direct impact on your bottom line.
General liability premiums for roofing contractors are typically rated on a combination of payroll and revenue. While the premium is not directly assigned per employee, you can allocate it proportionally for bidding purposes. A roofing company paying $8,000 per year for a $1M/$2M CGL policy with 10 employees is effectively spending $800 per employee on general liability. For a company paying $15,000 for the same coverage with 15 employees, the per-employee allocation is $1,000.
Commercial auto insurance allocation depends on how many employees drive company vehicles. If you insure five trucks at a total cost of $15,000 per year and five employees are assigned as primary drivers, the per-driver cost is $3,000. Employees who do not drive company vehicles still create auto exposure through hired and non-owned auto coverage when they drive personal vehicles to job sites or supply houses.
When preparing bids, you should include insurance costs as a direct job cost rather than burying them in overhead. The most accurate approach is to calculate your fully burdened labor rate, which includes base wages plus payroll taxes (approximately 7.65% for the employer's share of FICA), workers' comp premium, general liability allocation, and any other employee-related insurance costs. For a roofing laborer earning $20 per hour in a moderate-rate state with an average EMR, the fully burdened rate including all insurance and payroll taxes typically falls between $30 and $40 per hour. Failing to account for these costs in your bidding will systematically erode your profit margins.
To reduce your per-employee insurance cost, focus on the highest-impact strategies: lowering your EMR through safety programs and claims management, maintaining accurate payroll records to avoid audit surprises, properly classifying employees versus subcontractors, and separating clerical and sales payroll from your class code 5551 payroll where appropriate. Each of these steps reduces the denominator in your cost equation and improves your competitiveness on bids without sacrificing coverage.
