Every roofing company says it. It’s on every truck, every website, every door hanger that lands on your porch: licensed and insured. Four words that are supposed to mean something — and they do, when they’re actually true.
The problem? Most homeowners never verify either one. They hear the phrase, assume it checks out, and move on to comparing prices. That’s exactly how unlicensed contractors stay in business.
A Business Registration Is Not a Contractor’s License
This is where the confusion starts. In most states, registering an LLC or corporation is a basic legal step — it means the business exists on paper. That’s it. It says nothing about whether the person running it is qualified to tear off your roof and install a new one.
A home improvement contractor (HIC) license is a completely different thing. In New Jersey, for example, contractors are required to register with the Division of Consumer Affairs and carry a valid HIC number. That registration means the state has the contractor on file, they’ve met baseline requirements, and there’s a record homeowners can check if something goes wrong.
Here’s what to look for: a real HIC license number should be displayed on the contractor’s website, contracts, and marketing materials. If you can’t find one, that’s not an oversight — it’s a red flag. You can verify any New Jersey contractor’s registration directly through the state’s online lookup tool in about 30 seconds.
What Happens When an Unlicensed Crew Damages Your Property
This is the scenario nobody thinks about until it’s too late. An unlicensed crew cuts corners on flashing, misses a code requirement on ventilation, or damages your siding during a tear-off. Now what?
You have almost no recourse. Unlicensed contractors aren’t accountable to a licensing board. There’s no bond to file a claim against. Your ability to pursue damages in court gets complicated — in some states, contracts with unlicensed contractors are considered void, which means even a signed agreement may not protect you.
And here’s the part that really stings: your homeowner’s insurance may not cover damage caused by unlicensed work. Insurers can — and do — deny claims when they determine the work was performed by someone who wasn’t properly licensed. You’re left paying out of pocket for repairs on top of what you already spent on the original job.
“Insured” Doesn’t Mean What You Think Either
A contractor saying they’re insured could mean a lot of things. What you actually need to confirm is that they carry both general liability insurance and workers’ compensation coverage.
General liability protects your property. If a crew member puts a ladder through your window or a dumpster cracks your driveway, the contractor’s policy covers it — not yours.
Workers’ comp is the one most homeowners forget to ask about. If a worker gets injured on your property and the contractor doesn’t carry workers’ comp, you could be liable. Your homeowner’s policy might cover it, or it might not — and that’s not a question you want to answer after someone falls off your roof.
Ask for a certificate of insurance (COI) before work starts. A legitimate contractor will hand it over without hesitation. If they push back or make excuses, walk away.
How to Actually Verify Before You Sign
It takes five minutes and can save you thousands. Here’s what to check:
License: Ask for the HIC number. Look it up on your state’s consumer affairs website. In New Jersey, that’s the Division of Consumer Affairs contractor verification page. The number should match the business name and show an active status.
Insurance: Request a current COI directly from the contractor. Better yet, call the insurance company listed on the certificate and confirm the policy is active. Policies can lapse — a certificate from six months ago doesn’t mean coverage is current.
Manufacturer certifications: These aren’t required, but they add a layer of accountability. Programs like GAF Master Elite or CertainTeed Select ShingleMaster require contractors to meet ongoing standards for installation quality, training, and customer satisfaction. Only a small percentage of contractors qualify, and losing the certification means losing access to extended warranty programs — so there’s a real incentive to do the work right.
The Bottom Line
“Licensed and insured” should be the starting point of your vetting process, not the end of it. The contractors who actually carry proper licensing, active insurance, and manufacturer certifications aren’t bothered by you checking — they expect it.
If you’re starting a roofing project and want to skip the guesswork, find licensed roofers who can show you the credentials upfront. Verify before you sign. Your roof — and your wallet — will thank you.
