New Jersey has more unlicensed roofing contractors than almost any other state. Here's exactly what to check before you sign anything — and the red flags that should send you walking.
Why Choosing the Right Contractor Matters More Than the Brand of Shingles
The single biggest factor in how long your new roof lasts isn't the brand of shingles — it's the quality of installation. A GAF Timberline HDZ installed incorrectly will fail in 10 years. A mid-grade architectural shingle installed by a skilled, meticulous crew will last 30. New Jersey has a significant problem with unlicensed and underinsured roofing contractors, particularly after storm events when "storm chasers" from out of state flood the area.
7 Things to Verify Before Hiring a Roofing Contractor in NJ
1. NJ Home Improvement Contractor (HIC) Registration
In New Jersey, any contractor performing home improvement work over $500 must be registered with the NJ Division of Consumer Affairs as a Home Improvement Contractor. Go to njconsumeraffairs.gov and search the HIC registry. If a contractor can't give you their HIC number, walk away.
2. General Liability Insurance (Minimum $1 Million)
Ask for a Certificate of Insurance (COI) naming you as an additional insured. Call the insurance company to verify the policy is active. If a worker is injured on your property or your home is damaged during the project, the contractor's general liability insurance covers it — not your homeowners insurance.
3. Workers' Compensation Insurance
Without workers' comp, an injured worker can sue you as the property owner. Require a separate COI for workers' comp — this is non-negotiable.
4. Local References (Not Just Online Reviews)
Ask for 3 references from jobs completed in the last 12 months in Somerset County. Call them. Ask specifically: Did the crew show up on time? Was the site cleaned up daily? Were there any issues, and how were they handled?
5. Written, Itemized Contract
Your contract should specify: the exact materials (brand, product line, color), the scope of work (tear-off, decking inspection, flashing replacement, ice and water shield, ridge vent), the payment schedule, the start and completion dates, and the warranty terms. Never pay more than 10–15% upfront.
6. Manufacturer Certification
GAF Master Elite and Owens Corning Preferred Contractor certifications require training, insurance verification, and customer satisfaction standards. Certified contractors can offer enhanced warranty coverage that non-certified contractors cannot.
7. Physical Business Address in NJ
Verify that the company has a physical address in New Jersey, has been operating locally for at least 3 years, and has a track record in your county.
