Workers Comp vs General Liability: Two Essential Coverages Every Roofer Must Understand
Workers compensation and general liability are the two most critical insurance policies for any roofing contractor. They cover completely different risks, protect completely different parties, and are required for completely different reasons. Yet many roofers, especially those just starting out, confuse the two or mistakenly believe one can substitute for the other. Understanding the distinction is fundamental to protecting your business, your employees, and your ability to work.
What Workers Comp Covers
Workers compensation insurance covers your employees when they are injured or become ill due to their work. For roofing contractors, this includes falls from roofs and ladders, injuries from nail guns, saws, and other tools, heat-related illness, injuries from lifting heavy materials like bundles of shingles, burns from hot-applied roofing systems, and vehicle accidents while driving for work purposes.
When an employee is injured, workers comp pays their medical bills, a portion of their lost wages (typically two-thirds of their average weekly wage), vocational rehabilitation if they cannot return to their previous job, and death benefits to the employee's dependents if the injury is fatal. In exchange for these guaranteed benefits, the employee gives up the right to sue you for the injury. This is known as the exclusive remedy doctrine, and it is one of the most valuable protections workers comp provides to employers.
Workers comp is the most expensive insurance line for roofing contractors. Rates range from $18 to $55 per $100 of payroll depending on your state, whether you do residential or commercial work, and your experience modification rate. A roofing company with $400,000 in annual payroll at a rate of $30 per $100 pays $120,000 per year for workers comp alone. This single policy often costs more than all other insurance coverages combined.
What General Liability Covers
General liability insurance covers injuries and damage to third parties, meaning people and property that are not your employees. If a bundle of shingles falls off a roof and hits a homeowner, that is a GL claim. If your crew accidentally breaks a window, damages HVAC equipment on a commercial building, or causes water damage to a home's interior during a re-roofing project, those are GL claims. If a roof you installed three months ago leaks and destroys the homeowner's ceiling and furniture, that is a completed operations claim under your GL policy.
GL also covers personal and advertising injury, which includes claims like defamation or copyright infringement, though these are less common for roofers. More importantly, GL provides legal defense costs. If a homeowner sues you for a $50,000 property damage claim, your GL carrier provides an attorney, pays defense costs, and covers the settlement or judgment up to your policy limits. Defense costs are typically paid in addition to your limits, meaning a $50,000 settlement on a $1M policy does not reduce your remaining coverage by the amount spent on defense.
Why You Cannot Substitute One for the Other
A surprisingly common mistake among new roofers is assuming that GL covers everything, including employee injuries. It does not. General liability specifically excludes injuries to your own employees. If your roofer falls off a ladder and breaks his back, your GL policy will deny the claim. Without workers comp, you are personally liable for that employee's medical bills, lost wages, and potential lawsuit, which could easily exceed $500,000 for a serious fall injury.
Conversely, workers comp does not cover third-party claims. If your crew drops debris on a parked car, workers comp will not pay for the damage to the car. If a homeowner trips over your equipment and breaks an ankle, workers comp does not respond because the homeowner is not your employee. You need GL for every third-party claim.
This is why both policies are required by law in most states (workers comp) and by every contract and building permit (GL). They cover complementary risks with zero overlap. You need both, no exceptions.
How the Two Policies Interact
While workers comp and GL cover different risks, they interact in important ways. Your workers comp policy includes employers liability coverage, which responds to lawsuits that fall outside the workers comp system. For example, if an employee's spouse sues you for loss of consortium following a serious workplace injury, that claim falls under employers liability, not workers comp benefits. Your umbrella policy sits above both your GL and your employers liability, providing excess limits over both.
From a cost perspective, both policies are experience-rated, meaning your claims history directly affects your premiums. A large workers comp claim increases your experience modification rate (EMR), which increases your workers comp premium for three years. A large GL claim increases your GL premium at renewal. A roofer with a 1.3 EMR pays 30% more for workers comp than a roofer with a 1.0 EMR, and a single large GL claim can double your GL premium at renewal.
Common Roofing Scenarios and Which Policy Responds
Understanding which policy covers which scenario is critical for every roofer. If your employee falls off a roof and breaks his leg, workers comp pays. If a loose shingle slides off the roof and hits the homeowner's child, GL pays. If your crew's tear-off debris punctures the homeowner's car windshield, GL pays. If your employee develops a repetitive stress injury from years of nailing, workers comp pays. If a completed roof leaks six months later and destroys the homeowner's ceiling, GL completed operations pays. If your employee is injured in a company truck accident, workers comp pays for the employee's injuries and commercial auto pays for third-party injuries and vehicle damage.
The Cost of Being Uninsured
Operating without workers comp is illegal in most states and carries severe penalties including fines of $500 to $100,000 or more per day, criminal charges against the business owner, personal liability for all employee injury costs, stop-work orders that shut down your jobs, and loss of your contractor's license. Operating without GL means you cannot bid on any commercial work, most municipalities will not issue you a permit, and you are personally liable for every third-party claim arising from your operations.
For a roofing contractor, operating without either coverage is not just risky, it is a business-ending decision. A single fall from a roof can generate $200,000 to $1M in medical costs. A single completed operations claim can cost $50,000 to $500,000. These are not hypothetical numbers; they are common claim values in the roofing industry. Carry both policies, maintain them continuously, and build the premiums into your job pricing so every project contributes to your insurance costs.
