A roofer falls off a ladder on your property. He has no workers’ compensation. In New Jersey, that bill can land on your homeowners insurance, or on you directly.
Insurance covers the liability side. Registration and manufacturer certification cover the quality side, since a contractor has to be vetted on finances, track record, and workmanship before the state or GAF will stand behind them.
That’s why it pays to learn how to check if a roofer is insured in NJ before anyone climbs onto your roof. The whole check takes about ten minutes and a handful of direct questions.
This guide covers what to ask for, where to verify it, and the red flags that mean you should keep looking.
How Do You Check if a Roofer Is Insured in NJ?
To check if a roofer is insured in NJ, ask for a current certificate of insurance showing both general liability and workers’ compensation coverage, then confirm that coverage directly with the insurer listed on the certificate.
Also verify NJ contractor registration and any manufacturer certification, such as GAF Master Elite, before signing a contract.
Here’s the step-by-step version:
- Ask for a certificate of insurance before work starts, not after. A legitimate roofer produces one on the spot. A company that stalls, or promises to “send it later,” may not have current coverage to show you.
- Check who and what is on it. The named insured should match the exact business signing your contract, not a subcontractor or a different LLC. Confirm it lists both general liability and workers’ compensation, with policy dates that cover your project.
- Call the insurer listed on the certificate. A certificate only proves coverage on the day it was printed. A five-minute call to the agent confirms the policy is still active today.
- Ask to be added as a certificate holder for your project dates. Most agents can email an updated certificate within minutes, at no cost to the contractor.
Workers’ compensation is the line homeowners tend to skip past, and it’s the one that protects you most. If an uninsured worker gets hurt on your property, New Jersey premises liability rules can put you, not just the roofing company, on the hook for the medical bills.
| What to Check on the Certificate | Why It Matters |
| Named insured | Matches the company signing your contract |
| General liability | Covers property damage during the job |
| Workers’ compensation | Covers crew injuries, protecting you from liability |
| Policy dates | Active through your project’s start and finish |
How Do You Verify a Roofer’s NJ Registration Before Hiring in Monmouth County?
New Jersey doesn’t issue a traditional “roofer’s license” the way some states do. Home improvement contractors instead register with the New Jersey Division of Consumer Affairs under the Contractors’ Registration Act (N.J.S.A. 56:8-136 et seq.), and that registration number is what an NJ roofer license check is actually looking for.
A valid registration number starts with 13VH followed by a string of digits, and state law requires it to appear on the contractor’s contracts, invoices, and advertising. A company that can’t produce this number when asked has failed the check right there.
You can confirm a registration is active through the New Jersey Division of Consumer Affairs’ online License Verification System. Search by business name under Home Improvement Contractor. The listing shows whether registration is active, expired, or carries disciplinary history.
One thing worth flagging: New Jersey passed a law in 2024 to eventually replace this registration system with full licensure under a new state board. That change hasn’t taken effect yet, so registration, not licensure, is still what to check for today, in Monmouth County and everywhere else in the state.
What Does GAF Master Elite Certification Actually Tell You?
GAF Master Elite is a manufacturer credential, not a state requirement, and it answers a different question than registration does. Registration confirms a contractor is legally allowed to operate in New Jersey. GAF Master Elite confirms GAF itself reviewed that contractor’s work and stands behind it.
GAF re-reviews Master Elite contractors every year. Fewer than the top 3% of roofing contractors nationally hold the certification at any given time. It’s also what makes GAF’s strongest warranties available. Those depend on the installer’s certification tier, not just the shingles going on the roof.
A truck decal or a website badge isn’t proof by itself. Confirm the certification directly through GAF’s own contractor verification tool at gaf.com. Look up the company by name or zip code, and check that the listing shows Master Elite specifically rather than a lower tier.
Fortified Roofing holds GAF Master Elite Certified status, which is part of why our Signature Fortified Roof™ carries the warranty coverage GAF reserves for its top-tier installers.
What Red Flags Mean You Should Walk Away?
Most of these show up before you ever sign anything.
- Cash-only, or a big discount for paying the full amount upfront. A legitimate roofer invoices through the business named on their registration and insurance, not a personal Venmo account.
- No written estimate. A home improvement contract in New Jersey should spell out scope, materials, and price in writing. A verbal ballpark isn’t a contract.
- Refusing to produce a certificate of insurance, or refusing to let you call the agent. A five-minute request shouldn’t get a defensive reaction.
- High-pressure, sign-today-only pricing. A roof is a five-figure decision, and a contractor who won’t let you sleep on it isn’t doing you a favor.
- No verifiable local address. A crew that showed up after a storm with an out-of-state plate and no local office is worth researching before you hire, not after.
None of these guarantee a bad outcome on their own, but seeing more than one is reason enough to keep looking.

Frequently Asked Questions
How Do I Check if a Roofer Is Licensed and Insured in NJ?
Ask for a current certificate of insurance showing general liability and workers’ compensation, then confirm it directly with the insurer. Also check the contractor’s New Jersey Home Improvement Contractor registration number through the state’s License Verification System, and confirm any manufacturer certification, like GAF Master Elite, directly with the manufacturer.
What Insurance Should a NJ Roofer Carry?
New Jersey requires registered home improvement contractors to carry at least $500,000 in general liability coverage. Workers’ compensation is separate and just as important, since it protects you if a worker is hurt on your property.
Is GAF Master Elite the Same as Being Licensed?
No. GAF Master Elite is a manufacturer certification GAF awards after an annual review of a contractor’s work and customer satisfaction. New Jersey’s home improvement registration is a separate legal requirement to operate, and a roofer needs both, not one instead of the other.
