Roofing is one of the highest-risk trades, so roofer workers comp is among the most expensive — rates can run several times higher than low-risk jobs, often a significant percentage of payroll. Premiums are driven by the roofing class code, your state, your payroll, and your claims history. In nearly every state, workers comp is required once a roofing business has employees, and many general contractors require proof of coverage before subcontracting any roofing work.
This guide focuses on the cost and rate side — what roofers pay and why — plus state requirements. For broader coverage basics, our essential guide to workers compensation for roofers covers the fundamentals; here we drill into pricing.
Why Roofing Workers Comp Is So Expensive
Roofing carries some of the highest injury rates of any trade — falls, heat exposure, and equipment injuries are common. Insurers price that risk into the class code, so roofing rates sit near the top of the scale.
- Fall risk — Work at height drives both frequency and severity of claims.
- Severe injuries — When roofing accidents happen, they tend to be costly.
- High class-code rate — The roofing classification reflects this elevated risk.
What Determines Your Roofer Workers Comp Rate
- Class code — Roofing codes carry high rates; steep-slope vs. low-slope can differ.
- Payroll — Premiums are calculated per $100 of payroll, so wages directly affect cost.
- State — Roofing rates vary dramatically between states.
- Claims history (EMR) — A clean safety record lowers your experience modification rate; past claims raise it.
- Subcontractor use — Uninsured subs can be added to your payroll basis at audit.

State Requirements for Roofing Businesses
In nearly every state, a roofing company with employees must carry workers comp. Some states have especially strict rules for construction trades, and a few require coverage even for certain owners or single-person operations in high-risk classes. Confirm your state’s threshold before you take on a job. Roofing also overlaps with broader construction rules — see workers comp for construction and our look at common construction-related work injuries.

How Roofers Can Lower Workers Comp Cost
- Build and document a fall-protection and safety program to improve your EMR
- Report and manage claims quickly to limit severity
- Verify subcontractors carry their own coverage to avoid audit add-ons
- Classify employees accurately by their actual roofing duties
- Consider pay-as-you-go or a PEO to tie premiums to real payroll and access pooled rates
