Falls are the main hazard in roofing. In 2023 roofing contractors accounted for 110 fatal falls, 26 percent of all fatal falls in construction (BLS).
What comp costs per roofer in Illinois
The Bureau of Labor Statistics counts 5,300 roofers on payrolls in Illinois (May 2025), the 5th largest workforce among the 50 states and DC. The median wage is $37.45 an hour, 41% above the US median of $26.65.
Roofers make up about the same share of Illinois jobs as they do nationally (location quotient 1.00).
At the US median of $11.21 per $100 of payroll (Illinois does not publish its figure online), comp on one worker at that wage costs about $4.20 for every hour worked, or $8,732 a year full time. A 4-person crew comes to roughly $34,929 a year in premium before any experience mod.
Because premium is charged on payroll, who you hire moves the bill. Illinois pay runs from $22.41 an hour at the 10th percentile to $51.22 at the 90th, so the same rate costs $2.51 an hour on a new hire and $5.74 on a senior hand.
Workers comp requirements in Illinois
- Coverage required: 1 employee; construction is classed as extra-hazardous
- Owners and sole proprietors: In construction, owners and officers cannot opt out and must be covered
- State fund: Private market (no state fund)
- Waiting period: 3 work days; retroactive if off 14+ days
- Penalty for going without: Willful failure: up to $500/day (minimum $10,000) and Class 4 felony exposure
Because construction is classed as extra-hazardous, Illinois removes the owner/officer opt-out that most states allow.

If your crews work across the line, list those states under item 3.A or 3.C of your policy before the job starts. Rates follow the state where the work is done, not where your office is.
What moves a roofing comp bill
- Falls drive roofing claims, and one serious fall can push your experience mod well above 1.0 for three policy years. A written fall-protection plan and documented toolbox talks are what carriers ask to see before they offer a safety credit.
- Uninsured subcontractors are the most common audit surprise in roofing. If a sub cannot show you a certificate of insurance, the auditor adds what you paid them to your own payroll at the roofing rate.
- Estimators and salespeople who never go on a roof can often be classed separately at a far lower rate, but only if your payroll records show their hours apart from field work.
- Overtime premium (the extra half in time and a half) is excluded from comp payroll in most states. Record it separately so you are not charged the roofing rate on it.
