How to Choose a Roofer in NJ — 7 Things Every Homeowner Must Know
How to Choose a Roofer in NJ — 7 Things Every Homeowner Must Know
Choosing the wrong roofing contractor in New Jersey can cost you tens of thousands of dollars — in repairs, in legal fees, or in a roof that fails years before it should. Choosing the right one means a roof that lasts 30+ years, a warranty that actually covers you, and a job done by a crew you can trust.
Here are the 7 most important things every New Jersey homeowner must check before hiring a roofing contractor.
1. Verify the NJ Home Improvement Contractor License
In New Jersey, any contractor performing home improvement work — including roofing — must be registered as a Home Improvement Contractor (HIC) with the NJ Division of Consumer Affairs. This is not optional. It is the law.
You can verify any contractor's HIC registration at the NJ Division of Consumer Affairs website (njconsumeraffairs.gov). Simply search by business name or registration number.
Why this matters: An unlicensed contractor has no accountability to the state. If they do shoddy work or disappear with your deposit, you have very limited legal recourse. A licensed contractor is bonded, insured, and subject to state oversight.
Brandon Roofing has been a licensed NJ Home Improvement Contractor since 1990. We carry full general liability and workers' compensation insurance on every job in Morris County and Sussex County NJ.
2. Confirm They Carry Workers' Compensation Insurance
This is the one most homeowners skip — and it can be catastrophic. If a roofing worker is injured on your property and the contractor doesn't carry workers' compensation insurance, you can be held liable for their medical bills and lost wages.
Ask every contractor for a Certificate of Insurance (COI) that shows:
- General liability coverage (minimum $1 million per occurrence)
- Workers' compensation coverage
A reputable contractor will provide this without hesitation. If they can't or won't, do not hire them.
3. Ask Who Will Actually Do the Work
Many roofing companies in New Jersey are essentially sales organizations. They have a polished website, a professional salesperson, and a slick estimate process — but when it comes time to actually do the work, they subcontract it to a crew you've never met.
This is not inherently wrong, but it means you have no control over who is on your roof. The subcontractor crew may be excellent, or they may be cutting corners to maximize their margin on the job.
The best roofing contractors in NJ use their own trained, full-time crews. Ask directly: "Will your own employees be doing the work, or will you be subcontracting?" Get the answer in writing if possible.
At Brandon Roofing, we never subcontract. Our own crew does every job. The owner is on-site every day.
4. Check Google Reviews — Carefully
Google reviews are the most reliable public indicator of a contractor's quality in 2026. But not all reviews are equal. Here's how to evaluate them:
Look for:
- High volume (50+ reviews is meaningful; 10 reviews is not)
- Consistent 5-star ratings over multiple years
- Reviews that mention specific towns, specific jobs, and specific details
- Reviews that mention the owner by name
- How the company responds to any negative reviews
Be skeptical of:
- A sudden spike in reviews (could be purchased)
- Reviews that are vague ("great job!" with no details)
- Reviews from outside the service area
- No response to negative reviews
Brandon Roofing has a 5.0-star Google rating with 55+ verified reviews from homeowners across Morris County and Sussex County NJ. Every review is from a real customer in a real town.
5. Understand What's in the Estimate
A professional roofing estimate should be detailed and specific. It should include:
- Exact materials: manufacturer, product line, color, and weight
- Scope of work: full tear-off vs. overlay; how many layers are being removed
- Warranty terms: both the contractor's labor warranty and the manufacturer's material warranty
- Payment schedule: typically a deposit at signing, progress payments, and final payment on completion
- Timeline: start date and estimated completion date
- Permit information: who is responsible for pulling permits (required for most full replacements in NJ)
If an estimate is vague about any of these — especially materials and warranty — ask for clarification before signing. A contractor who can't or won't specify the exact materials they're using is a red flag.
6. Know the Difference Between a Tear-Off and an Overlay
In New Jersey, most roofing contractors will recommend a full tear-off (removing all existing shingles down to the decking) rather than an overlay (installing new shingles over existing ones). Here's why:
Tear-off advantages:
- Allows inspection of the decking for rot, damage, or inadequate ventilation
- Provides a clean, flat surface for the new shingles
- Required by most manufacturer warranties
- Required by NJ code if there are already two layers of shingles
Overlay advantages:
- Cheaper upfront
- Faster installation
The problem with overlays is that they hide existing damage, add weight to the structure, and typically void manufacturer warranties. Most reputable NJ roofing contractors will not do an overlay unless the existing roof is in excellent condition and there is only one existing layer.
Ask your contractor directly: "Are you doing a full tear-off or an overlay?" If they're recommending an overlay to save money, make sure you understand the trade-offs.
7. Get Multiple Estimates — But Don't Just Choose the Cheapest
Getting 2–3 estimates from different contractors is always a good idea. But the cheapest estimate is not always the best value. Here's how to compare estimates properly:
- Are they using the same materials? (GAF Timberline HDZ vs. a generic shingle is a significant quality difference)
- Are they both doing a full tear-off?
- Do both warranties cover the same things?
- Does the cheaper contractor have the same license, insurance, and reviews?
A $2,000 difference in price is meaningless if the cheaper contractor uses inferior materials, skips the tear-off, or disappears when you have a warranty claim.
The Bottom Line: How to Choose a Roofer in NJ

- Is licensed and insured (verifiable)
- Has 5-star reviews from real local customers
