Liability insurance for roofers: what does it cover and what does it cost?

General liability (GL) insurance covers third-party bodily injury, property damage, and personal/advertising injury caused by your roofing work — plus the legal defense costs. It does not cover injuries to your own crew (that's workers' comp). Most roofers pay roughly $116 to $1,158 per month, driven mostly by state, revenue, and the limits a client demands.

Because roofing is a high-risk trade — crews work at height, drop tools, and operate torches and heavy equipment — carriers price it above most contracting classes, and clients almost always require proof of it before work begins.

What general liability covers

A GL policy responds when your operations harm someone outside your business. According to Vouch, the core coverages are bodily injury to non-employees, property damage to others, personal and advertising injury (libel, slander, copyright claims), products and completed operations, a small medical-payments section for minor injuries, and damage to premises you rent.

For roofers specifically, JobNimbus gives concrete examples: a dropped hammer that strikes a homeowner, a ladder that falls against a customer's car, a torch that scorches a cedar fence, or a pallet of shingles that cracks a driveway. Critically, GL includes completed operations — claims that surface months or years after a job wraps, which matters in roofing because leaks often appear long after the crew leaves. See our liability coverage requirements page for how limits are structured.

Why clients require it

Most general contractors, commercial property owners, and many residential clients demand a certificate of insurance (COI) before a roofing crew sets foot on the property — they want proof that if something goes wrong, someone other than them pays. JobNimbus notes the industry-standard limit is $1 million per occurrence and $2 million in aggregate, and larger commercial GCs increasingly require higher aggregate limits. Our general liability for roofers explainer breaks down how these COIs work.

Typical cost factors

GL premiums for roofers swing widely by state. MoneyGeek reports general-liability costs for roofing contractors ranging from about $396 per month in West Virginia to $1,158 per month in California. NEXT Insurance reports that 97% of its roofing customers pay $116 on average per month, with prices ranging between $66 and $670 per month — typically with per-occurrence limits of $300,000 to $1 million and aggregate limits of $300,000 to $2 million.

The biggest cost drivers are your state and local claim frequency (weather-prone states run higher), annual revenue and payroll, the coverage limits clients require, your claims history, and whether you do residential or higher-exposure commercial work. Note that GL is separate from workers' compensation, which covers your employees' on-the-job injuries — see workers' comp for roofers.
