Checks before work starts, New Jersey
Questions to settle with a roofer before work starts in Clark
Here is what New Jersey's own pages say about contractors, contracts, payments and roof paperwork. A table follows with the building office in Clark, Cranford and Linden. Everything reported is a published rule; none of it speaks for a contractor.
The state register, and what it leaves unsaid about roofs
Per Consumer Affairs' FAQ, a contractor who does or sells home improvement work for a living registers each year with the Division, exemptions aside. Ads, business cards and commercial vehicles are to show the registration number. Liability cover is part of it too. The same page says registrants hold a commercial general policy carrying $500,000 or more per occurrence. It adds that the Act supersedes any municipal law licensing home improvement contractors.
A wrinkle worth knowing: the state's list of home improvements includes driveways, porches, windows, siding and much else, but never names roofs or gutters. A closing catch-all takes in other changes, repairs or improvements to residential property. Only the Division can say whether a particular job counts.
A licensing board in the statute, and the clause that holds it back
Under P.L. 2023, c.237, a nine-member licensing board covers home improvement contractors and home elevation contractors. The board may issue limited specialty services licenses, and the statute names roofing among its examples. Sections 9 through 13 of the law are held in abeyance. They begin on a date tied to the board's rulemaking: the first day of the sixth month following adoption.
The sources do not say whether those rules have been adopted. Ask the Division which regime applies on the day a contract is signed, and use the lookup described next for the working check.
Using the state's lookup page
The Division's verification page has a person search and a business search, and Home Improvement Contractors is one of the professions in its list. Any search field needs two characters at least. Begin with the number the contractor shows on paper, then try the business name with the city.
A 2012 release from the same Division gave 800-242-5846 for checking a contractor's status by phone. Numbers change, so rely on the one printed on the Division's current pages.
What a contract above $500 has to say
Any home improvement priced above $500 needs a written contract, and a change to it needs one too. Everyone signs, and the wording has to be legible and plain.
On paper, look for these items. The seller's name and business address, and the sales agent's if one was involved. A summary of the job and its principal materials, down to make, model and grade where those apply. The total price, or the hourly rate for time-and-materials work. The dates the job starts and ends. Any mortgage or security interest tied to financing. Any promise in writing about products, materials, labor or services.
Matching payments to progress
The Division's 2012 consumer release offers a rule of thumb for paying. It suggests no more than a third up front, a third at the midpoint and the last third when the work is done. It is a yardstick, not a legal cap, but it gives a contract a number to be measured against.
That release also urges owners to ask to see the contractor's liability insurance policy and to phone the insurer to confirm it is valid. It also suggests asking people they know for recommendations, and keeping card numbers and financial details away from strangers online or by phone.
Signing off too early, and the inspection papers
Under the Division's unlawful-practices rule, a seller cannot ask for a completion certificate or final payment while the work is unfinished under the contract. Nor can a seller begin before the permits the job requires are issued. When construction ends, the buyer receives copies of inspection certificates ahead of final payment or any completion slip.
A roof job may need no permit at all, so the contract is the place to say which papers apply.

Reroofing a detached house: what the state exempts
The state's alert on changes effective March 5, 2018 lists existing roof covering as ordinary maintenance for detached one- and two-family dwellings. Repairs and replacements both count, in any amount, total replacement included. Exterior gutters and leaders are on that list too. Ordinary maintenance means work performed without a permit under the Uniform Construction Code. The construction regulations (section 5:23-2.7) add that the work is exempt from a permit application and from any notice to the construction official.
The code's limits stay in force. Work that affects structural or fire safety, or cuts a loadbearing wall or a structural beam, is not ordinary maintenance. The roofing line names detached one- or two-family homes only, so a twin, a townhouse or a larger building is a question for the building office.
The 2024 codes and the date they were adopted
The state's current-codes page lists two New Jersey editions from 2024, both shown as adopted August 17, 2026. One is the International Building Code. The other is the International Residential Code, which covers one- and two-family dwellings. The state's page does not describe how the changeover treats a contract signed now.
Ask the roofer and the building office which edition governs, and let the contract name it.
Who picks the roofer when an insurer is involved
Insurance department pages on storm claims list four things. Make temporary repairs to protect the property from more loss. Keep every receipt. Cooperate with the claim adjuster. Write notes on each conversation. The insurer is to supply a copy of its damage estimate and, if asked, the name of a contractor who will do the job at that price.
Nobody has to use the insurer's suggested contractor. If part of a loss is excluded, the company has to explain how.
Still unsure about an answer a roofer gave?
Call (732) 574-5073 and talk through what you were told, the town and the roof. Have the street address ready. Tenants bring the same notes to the owner.
