Why "licensed & insured" actually matters
"Licensed and insured" gets repeated so often in home services advertising that it can start to sound like filler. It isn't. These two things are the practical foundation of your legal and financial protection when a crew is working on your roof. Here's what each one actually does.
What a contractor's license actually verifies
Licensing requirements vary by state and sometimes by locality, but the general idea is consistent: a licensed contractor has demonstrated a baseline of competence, has registered with the state or local authority, and can be held accountable through that body if something goes seriously wrong. Depending on where you live, licensing may involve:
- Passing a trade or business exam
- Proof of a minimum amount of experience
- Registering a real business entity with a traceable address
- Maintaining the license in good standing, which can be checked and can be revoked
An unlicensed contractor may still do fine work — but if a dispute arises, you have far fewer avenues for recourse, and in many states, you may have no legal path to their license board at all because there isn't one to file with.
What insurance actually protects you from
This is the part homeowners underestimate most. Roofing work involves real risk — falls, dropped tools, damaged property. Two types of coverage matter:
- General liability insurance — covers damage to your property caused by the contractor's work, like a dropped tool cracking a window or a mishap damaging your siding.
- Workers' compensation insurance — covers medical costs if a worker is injured on your property. Without it, depending on your state and your own homeowner's policy, you could potentially be held liable for injuries that happen on your roof.
Ask to see a current certificate of insurance, not just a verbal assurance. A legitimate company can produce one without delay.
Permits
Many roof replacements require a building permit, and licensed contractors are generally set up to pull one. Permitted work typically gets inspected against code, which is a meaningful check on quality — a bad roof job is far more likely to get caught before it becomes a bigger problem down the line. Unpermitted work can also complicate a home sale later, when the lack of permit history surfaces during due diligence.
Warranty coverage
Materials often come with a manufacturer's warranty, but many of those warranties require installation by a certified or licensed installer to remain valid. A workmanship warranty from the contractor — covering their own labor, separate from the materials — is also far more meaningful when it comes from an established, licensed business that's likely to still be around if you need to make a claim in a few years.
How this ties to our vetting standard
License verification and insurance verification are the first two checks in our vetting standard, before a roofer is ever added to our roster. We confirm active licensing for the roofer's state and locale, and current general liability (and workers' comp, where applicable) — then periodically re-verify. It's the substance behind the word "vetted." Read more on our about page.
