Hiring the wrong roofing contractor can cost you thousands of dollars and leave you with a roof that fails prematurely. With so many companies competing for business — especially after major storms — knowing who to trust is more important than ever. This guide walks New Jersey homeowners through exactly what to look for.
1. Verify NJ Licensing and Insurance
In New Jersey, all home improvement contractors are required to be registered with the New Jersey Division of Consumer Affairs as a Home Improvement Contractor (HIC). Before you sign anything, ask for the following documents and verify them:
- NJ HIC Registration Number — searchable on the NJ Division of Consumer Affairs website
- Certificate of General Liability Insurance — protects your property if damage occurs during work
- Workers’ Compensation Insurance — protects you from liability if a worker is injured on your property
Any reputable roofing contractor will provide these documents without hesitation. If a contractor refuses or delays, walk away.
2. Check Local Reviews and References
Go beyond the company’s own website. Search Google Reviews, the Better Business Bureau (BBB), and Houzz for genuine customer feedback. Look for:
- How long the company has been operating in New Jersey
- How they respond to negative reviews or complaints
- Whether reviewers mention consistent team members — a sign of a stable, professional workforce
Ask the contractor for references from recent local jobs in your area. A confident, established contractor will be happy to connect you with past customers.
3. Always Get Multiple Written Estimates
Never accept a verbal quote. Get at least three written estimates before making a decision. A proper roofing estimate should clearly include:
- Brand and type of materials to be used
- Itemized labor costs
- Project timeline from start to completion
- Warranty information for both materials and workmanship
- What happens if additional damage is discovered once work begins
Be cautious of any estimate that is dramatically lower than the others. It almost always means substandard materials, inexperienced labor, or hidden costs that will appear later.
4. Watch Out for Storm Chasers
After any major NJ storm, out-of-state contractors flood the area with attractive quick-deal offers. These “storm chasers” are a well-known problem across New Jersey and should be avoided at all costs. They often:
- Demand large upfront deposits and then disappear
- Use cheap, off-brand materials that fail early
- Operate without proper NJ licensing or insurance
- Offer warranties that are impossible to enforce once they have left the state
Always work with a locally established company that has a real track record and a physical presence in your community.
5. Understand Your Warranty Options
A quality roofing job comes with two types of warranties that you should understand before signing:
- Manufacturer Warranty — covers defects in the roofing materials themselves (shingles, underlayment, flashing). Standard warranties range from 25 years to lifetime coverage.
- Workmanship Warranty — covers errors made during installation by the contractor. This is where many contractors differ significantly.
Contractors who are certified installers for manufacturers like GAF, Owens Corning, or CertainTeed can often offer enhanced warranty protection that standard contractors cannot.
