Roofing Contractors in Warren, Watchung and Green Brook, NJ: A Guide

We did the homework here.
For the places actually worth your time, money and babysitter, follow me: @tiffanyknowsnj.

The Guide: Roofing Contractors in Warren, Watchung and Green Brook, NJ

New Jersey does not license roofers. It registers them — and it registers them to a legal entity, not to the name painted on the truck. Every company in the table below holds a Home Improvement Contractor registration: the number that begins 13VH and runs eight digits after it. It is issued by the Division of Consumer Affairs, it is free to look up, and it takes about ninety seconds.

Warren, Watchung and Green Brook hold 192 active home improvement registrations between them — 118 in Warren, 40 in Watchung, 34 in Green Brook, counted at the state registry on September 4, 2026. Three of those companies are roofers. That is the shape of this market: a great many contractors live here, and almost none of them roof here. The rest of this guide is the companies that travel in, and the record behind each of them.

How We Selected These Companies

This guide covers three places: Warren, Watchung and Green Brook.

A company appears here if it installs, repairs or replaces residential roofs for homeowners in those towns, publishes roofing as a named service on its own website, and holds a New Jersey Home Improvement Contractor registration that the state records as active. That is the whole test. It is not a test of size, of price, of how long a company has been trading, or of what we think of its work. Thirty-three companies meet it and are in the table.

A company that trades from somewhere else is here only if it says on its own site that it works in one of these towns, or that it works in Somerset County. Where it says neither, it is not here, however close it is. Two companies verified for the neighbouring Bridgewater guide are absent for exactly that reason.

What a company publishes about itself is not the criterion. It is the content. Where a business publishes a registration number, this guide prints it and reports what the state record says about it. Where a business publishes nothing, this guide says so plainly and dates the statement. Neither is a compliment or a complaint. Both are facts about a website on a particular day.

About This Guide

This guide is produced by Garden State Circle. Companies appear here because they meet the criteria described above — they perform residential roofing work for homeowners in the towns this guide covers, publish it as a service, and hold an active state registration. That is a test, not a judgment, and it is the only route onto this page. No company can pay to be included in this guide, to be listed higher, or to change what the comparison table says about it. Companies are listed alphabetically, and every detail in the table was verified against each company’s own website and against the New Jersey Division of Consumer Affairs registrant record in September 2026. Five companies were added to the table on September 4, 2026, in the hours after it was first published, and their entries say so.

Everything under the heading that begins this guide is governed by the rules above, on every guide we publish. Where a sponsor’s message appears above that heading, it is paid for and labelled, and it buys nothing in the guide. Garden State Circle is supported by the businesses that participate in it. Participation pays for our ongoing work: keeping a business’s entry accurate, re-checking its record, and publishing a page of its own details that the business maintains. There is no paid placement in this guide. Participation does not buy a place here, a position here, or anything the comparison table says.

Garden State Circle is published in New Jersey by Tiffany and Jake Slowinski and covers Warren, Watchung and Green Brook. Contact the publisher at jake@gardenstatecircle.com. How every guide is made, in one place: how every guide is made.

Which of These Companies Is Actually in These Towns

Most homeowners asking whether a roofer is “local” are really asking two questions at once: will they come out for a repair rather than only a full replacement, and will they still be reachable in two years if the flashing leaks. Geography is only part of that, and it is the part that is easiest to check.

On geography this market is closer to the Somerset Hills than to Bridgewater. Three companies in the table are registered inside these three towns — David Anderson Construction on Stirling Road in Watchung, Liam’s Construction in Green Brook, and Stuart Home Improvement on Mountain Boulevard in Warren. One more, E & W Precision Roofing, holds an active registration recorded in Warren and sits below the table for the reason given there.

Two of those three are worth reading carefully. Stuart Home Improvement’s published address is a private mailbox at a Mountain Boulevard address, not a yard; the company is a restoration firm with roofing as one of its named services. Liam’s Construction publishes its town and no street at all. Neither is a mark against anybody — roofing crews work out of trucks — but a Mountain Boulevard address in Warren is not the same kind of thing as a Stirling Road address in Watchung, and the table cannot show you that difference.

One more works from close by and names this market on its own site: DP Roofing & Contracting, of North Plainfield, which trades online as Done Perfect Roofing and names Warren Township among the towns it serves. Everyone else drives in. From immediately around the market: Powell’s Roofing & Siding from Garwood, which carries a Warren page of its own; Hammer Exteriors from a Campus Drive office in Somerset; Blue Nail Exteriors from Montville, with separate Warren and Green Brook pages. From the Bridgewater and Somerville side, where most of the county’s roofers are: Arctic Roofing & Restoration, Lasting Construction, Levs Construction, Markey Windows Doors & More, Tetti Roofing, Tyler Roofing and W.C. Construction, each naming Warren or Watchung or Green Brook on its own site. Further out and travelling in: Hunterdon Roofing from Lebanon, Magnolia from Union, Matute Roofing from Wayne, New Jersey Siding & Windows from Randolph and Superior Siding & Windows from Rockaway.

One thing this market does that the others do not: four separate companies file Warren Township under the wrong county on their own websites. Powell’s lists Warren under Union County. Kepo, Magnolia and MD Contracting each name “Warren” in a list of counties, which is Warren County in the north-west of the state, sixty miles away, and not Warren Township at all. We treated a county named “Warren” as a county and a town named “Warren” as a town, and the table reflects that.

The Companies, Compared

Checked against the New Jersey Division of Consumer Affairs Home Improvement Contractor registration search.

Registrations, registered entity names, statuses and towns were verified against the New Jersey Division of Consumer Affairs registrant record, and services and credentials against each company’s own website and the manufacturer directories named in the entries, in September 2026.

Registered here, and the second test could not be run

E & W Precision Roofing LLC holds registration 13VH13425100, which the state records as active in Warren, and Owens Corning lists it as a Preferred Contractor. Its own domain answered when we asked for it on September 4, 2026 and returned no readable page — no services, no address, no towns. The second half of our test is a company’s own site saying what it does, and there was nothing to read. It is here so that a homeowner who has been handed this name can find the record. Third-party listings place it variously in Warren, Watchung and Dunellen; the state has it in Warren, and that is the only one of those we ran ourselves.

A Note on Reading the Registration Column

Twenty-one of the thirty-three companies in the table publish a New Jersey registration number on their own website. That is the first thing the table shows, and on its own it is only mildly interesting. The second thing it shows is the reason the column is split in two.

The registered name is often not the trading name. Bellari Home Remodeling’s registration is held by Somerville Aluminum Co., Inc. — the name the company traded under for decades. Powell’s Roofing & Siding is registered as Powell’s Home Improvements, L.L.C. Blue Nail Exteriors is registered as Blue Nail LLC. MD Contracting & Roofing is registered as Michael & Danielle Deegan Contracting LLC. Express Roofing NJ is registered as Express Services LLC. Levs Construction is registered as Lev’s Construction, with an apostrophe. Mighty Dog Roofing of Bridgewater is registered to JDC Property Management Company LLC. Every one of those is lawful, ordinary and invisible to a homeowner typing a company name into the state’s search box — which matches the registered name from its first letters and returns nothing for the name on the estimate.

The registered town is not always the published town. Matute Roofing publishes Wayne and is registered in Towaco. Hammer Exteriors publishes a Somerset office and is registered in South Plainfield. Proven Contracting publishes Bridgewater and is registered in Livingston, one of the four offices it lists. Mighty Dog Roofing of Bridgewater works from a Bridgewater suite and is registered in Mount Laurel, in Burlington County, because the registration belongs to the franchisee. A registered office and an operating office are different things and a company is entitled to both — but a homeowner checking a number has no way to know which one they are looking at.

One company publishes the wrong state’s number. Hunterdon Roofing, Siding & Window Company displays a Pennsylvania registration, PA161132, and not its New Jersey one, 13VH00209500, which is active in Lebanon. A homeowner who checked the published number against New Jersey’s registry would find nothing.

How to check a registration yourself

Search the New Jersey Division of Consumer Affairs licensee verification for Home Improvement Contractors, using the business search rather than the individual one. You can search by the 13VH number if you have it, or by the beginning of the registered name — the name search matches from the start of the name, so a partial word at the front works and a word from the middle does not. The result gives the registered entity, the number, the status and the town. It is free.

What the registration is, and what it is not

A 13VH registration means the business has registered with the state, carries commercial general liability insurance of at least $500,000 per occurrence, and is subject to the Contractors’ Registration Act. It is not a competency examination and it is not a trade license — New Jersey does not test roofers the way it tests electricians, plumbers or heating contractors. It tells you a business exists on the record and can be found again. That is worth having and it is not the same as skill.

Manufacturer certification is the closest thing this trade has to a graded credential, which is why it has its own column. GAF Master Elite, Owens Corning Platinum Preferred and CertainTeed SELECT ShingleMaster are awarded by the shingle manufacturers, carry installation-training and insurance requirements, and are what makes the long manufacturer warranties available in the first place. Where the column says “GAF directory”, we read the tier off GAF’s own public contractor listing; where it says “as published”, we read it off the company’s site and did not check it at the manufacturer.

The Companies

Arctic Roofing & Restoration, Bridgewater

Arctic Roofing & Restoration describes itself as a Bridgewater-based residential roofing company serving Somerset and Middlesex counties, and publishes roof replacement, emergency repair, storm-damage restoration and insurance-claim work as its services.

It publishes no registration number and no street address; GAF’s contractor directory lists it as GAF Certified Plus at a Route 202 suite in Bridgewater, and the state records ARCTIC ROOFING LLC as active in Bridgewater under 13VH13490400.

Bellari Home Remodeling, Branchburg

Bellari Home Remodeling works from County Line Road in Branchburg and publishes roofing, siding and windows among its services; its own site says the company was founded in 1950 and was known for many years as Somerville Aluminum. That is still the registered name — SOMERVILLE ALUMINUM CO., INC, active in Branchburg under 13VH01723200 — which is why a search under “Bellari” returns nothing. It publishes no town list; it names Somerset County, and its premises are in it. It describes itself as a ProVia certified installer and a VELUX Certified Installer.

Benchmark Siding Co., Branchburg

Benchmark Siding Co. is owned and operated by David Carman, who its site says has run it since 2005. Its published services are vinyl siding, cultured stone, window and door installation, roofing installation and cellular PVC trim, and it names Somerset County as its territory with town pages for Branchburg, Bridgewater, Hillsborough, Readington, Clinton and Montgomery.

Its service-area page names Somerset County — Watchung, Warren, Franklin and Montgomery — plus towns in Essex, Union and Morris. It publishes neither a registration number nor a manufacturer certification on its own site; the state records DAVID ANDERSON CONSTRUCTION LLC as active in Watchung under 13VH06606300, and GAF’s directory lists it as GAF Certified at the same Stirling Road address, in business since 2011.

DP Roofing & Contracting, North Plainfield

DP Roofing & Contracting trades online as Done Perfect Roofing, publishes its registration, 13VH01844800, and lists residential and commercial roofing, roof repair and inspection, chimney work, solar roofing, attic vents and storm and insurance work as its services. It names Somerset among eleven counties, with Bridgewater, Hillsborough, Warren Township, Bedminster, Edison and Parsippany-Troy Hills among the towns; it publishes no street address. Its site describes the company both as GAF Certified and as GAF Master Elite, while GAF’s own directory lists it as GAF Certified Plus at a Somerset Street address in North Plainfield, in business since 1996 — we print all three and do not choose between them. The state records DP CONTRACTORS as active in North Plainfield. Added to this guide on September 4, 2026, when its site was read to name Warren Township.

Levs Construction works from West Cliff Street in Somerville and lists Green Brook, Warren and Watchung under Somerset County on its areas-we-serve page, and describes itself as a family-owned, woman-led company that uses its own in-house crews rather than subcontractors.

It describes itself as a CertainTeed SELECT ShingleMaster and publishes no GAF or Owens Corning credential.

Its own site files Warren under Union County; Warren Township is in Somerset County.

Proven Contracting, Bridgewater

Proven Contracting works from Thruway Drive in Bridgewater — one of four New Jersey offices it lists, alongside Livingston, Randolph and Long Valley — publishes its registration, 13VH08608400, and names Somerset among the eleven counties it serves. It names David Curcio as managing partner and Ryan Watson as general manager and co-founder, describes itself as GAF Master Elite, James Hardie Certified and Tamko Diamond, and publishes an EPA Lead-Safe firm number, NAT-F124892-3.

Stuart Home Improvement, Warren

Stuart Home Improvement publishes an address on Mountain Boulevard in Warren — second floor, PMB #4776, a private mailbox rather than a yard — and names Watchung and Warren first in its town list, ahead of Basking Ridge, Westfield, Summit, Bridgewater, Chatham, Bernardsville, Berkeley Heights and Scotch Plains. It presents itself primarily as a restoration company, with roofing as a named service block covering replacement, repair, leak detection, emergency tarping, storm damage and flat systems alongside water and fire damage work. It describes itself as a GAF Certified Residential Roofing Contractor with Enhanced Warranty Factory Trained status, and publishes no registration number, saying only “NJ Licensed & Insured”; the state records STUART HOME IMPROVEMENT LLC as active in Warren under 13VH11792300.

Superior Siding & Windows, Rockaway

Superior Siding & Windows works from Rockaway and names Somerset County among the six counties on its locations page, with Bridgewater, Somerville, Bedminster, Bernards, Basking Ridge and Far Hills among the towns; it names none of this guide’s three. Its published services are siding, roofing, windows, doors and masonry, with Alside, ProVia and Marvin as the brands it names. It publishes no registration number and no street address; the state records SUPERIOR SIDING & WINDOWS, LLC as active in Rockaway under 13VH01107800.

Tetti Roofing, Bridgewater

Tetti Roofing works from a Grove Street suite in Bridgewater, publishes its registration, 13VH13842500, and does roofing only — replacement, repair, maintenance, inspection and financing. Its Somerset County page names Warren, Watchung and Green Brook, and it carries a Warren roofing page of its own; it also covers Middlesex and Hunterdon. It offers a twenty-year workmanship warranty of its own alongside GAF’s fifty-year manufacturer warranty, and GAF lists it as GAF Certified. The state records TETTI ROOFING LLC as active in Bridgewater.

Tony Balsamo & Son

Tony Balsamo & Son publishes its registration, 13VH01883400, heads its services “Roofing, Siding & Repairs”, and names Somerset, Middlesex and Union counties and Central New Jersey as its territory. It describes itself as a GAF Certified Roofer. It publishes no street address and no town of its own; the state records TONY BALSAMO SIDING CONTRACTOR, INC. as active in Piscataway. Its about page says it has been serving Belle Mead and surrounding areas for years; directory listings place it variously in Belle Mead and in Piscataway. Piscataway is the one the state has, and it is the only one we ran. Added to this guide on September 4, 2026, when its site was read to name Somerset County.

True North Roofing, Branchburg

True North Roofing publishes its registration, 13VH13971300, describes itself as a GAF Certified Installer with “20+ years experience”, and names Hunterdon, Morris, Somerset, Middlesex and Mercer counties as its territory. It does roofing — inspections, installations, repairs — and gutters, is veteran-owned and publishes a GAF Roofs for Troops rebate; it publishes no street address, and GAF’s directory lists it at a Route 202 suite in Branchburg. The state records TRUE NORTH ROOFING LLC as active in Branchburg. A similarly named domain, truenorthroofingllc.com, redirects to an Arizona business and is not this company.

Tyler Roofing, Bridgewater

W.C. Construction, Bridgewater

W.C. Construction works from Washington Valley Road in Bridgewater, publishes its registration, 13VH10064100, and names Warren among the sixteen towns it serves, with Somerset among six counties. Its site describes the company as GAF Certified and names CertainTeed Master Shingle and ProVia among its credentials, and its siding page offers a fifteen-year warranty on labour. Its own pages give its tenure two ways — “over a decade” on the home page and “over 30 years” on the siding page — so we quote both rather than choose. The state records WC CONSTRUCTION LLC as active in Bridgewater.

Named Here, and Not in the Table

Five companies came up in this market and are not in the table above. Naming them and saying why is part of what the table is for.

The Great American Roofing Company, Warren, publishes NJ License # 13VH00152900 on its contact page, alongside the entity name on that page — CLM Enterprises, LLC dba The Great American Roofing Company NJ — and says it has been serving New Jersey for over forty years, as an Owens Corning preferred contractor. We ran that number at the Division of Consumer Affairs on September 4, 2026. We print a registration only when the state records it as active on the day we check, and we print nothing else about a named business’s standing. If that changes, or if we have the wrong number, write to us and the row goes in.

Basking Ridge Roofing Co., which trades as Father & Sons Construction, publishes roofing contractor pages of its own for both Warren and Watchung and a Somerset County list naming Green Brook as well. It publishes no registration number, saying only “Licensed & Insured”, and no manufacturer certification. We could not find a registration under either name in September 2026. That is a statement about our search, not about the company — a registration held in an owner’s name or under a different legal entity would not surface in the searches we ran, and that is a common and entirely lawful arrangement.

Deegan Roofing Company, Scotch Plains, publishes a Watchung page and names Somerset among its counties; it publishes no registration number, and we could not find one under that name in September 2026. The same sentence applies. It publishes no Warren and no Green Brook page.

Ace Exterior Solutions LLC holds an active registration recorded in Watchung. We could find no website of its own — the only site under that name belongs to a company in Wisconsin — and no manufacturer directory listing, so neither half of the second test could be run. Doctor Scrubs Contracting & Exterior Solutions LLC holds an active registration recorded in Warren; its own site would not open for us on September 4, 2026, and nothing we could reach named roofing as a service.

Two companies verified for our Bridgewater guide are deliberately absent. Intira LLC describes its territory as “Central and Northern New Jersey” and RDS Remodeling as “Central New Jersey”; neither names a town in this guide, and neither names Somerset County. Both are real, registered and working nearby. Under this guide’s test they are not here, and if either adds a town or a county to its site, they go on.

The Question This Table Cannot Answer Yet

Every company in the table lists roof repair as a service. Very few will actually come out and quote a single slipped shingle or a leaking flashing detail on a house they did not roof, and no website in this trade answers that question honestly, because there is no commercial reason to. It is, for most homeowners most of the time, the only question that matters.

We are asking it directly, company by company, and the answers will be published here as they arrive. One has landed already: Proven Contracting told us plainly that yes, they do small repairs. Every other company on this page has been asked the same question. If you have called a roofer in Warren, Watchung or Green Brook about a small repair, we would like to know what happened — whether they came, how long they took, and whether they quoted the repair or only a replacement. Write to admin@gardenstatecircle.com.

Wal Contracting heads its own site “Franklin Park, NJ Roofing • Franklin Township Roofer” and publishes two registration numbers, the New Jersey 13VH12353900 and the Pennsylvania PA191643. Its published services run from premium residential roofing in slate, asphalt shingle and cedar shake to commercial flat roofing in TPO and EPDM, custom copper work, siding, windows, doors and renovations, and it names Somerset and Middlesex counties with Princeton, New Brunswick, Freehold, Bordentown, Trenton, Jersey City, Keansburg, Newark and Pottersville among its towns. It describes itself as a Certified GAF Contractor and publishes no street address; the state records WAL CONTRACTING LLC as active in Franklin Park, and GAF’s directory lists it on Vetter Drive there as GAF Certified, in business since 2021. Added to this guide on September 4, 2026, when its site was read to name Somerset County.

Does a roofer in Warren, Watchung or Green Brook, NJ need a license?

Not a trade license. New Jersey does not examine or license roofers the way it licenses electricians, plumbers and heating contractors. Home improvement contractors register with the state under the Contractors’ Registration Act — the 13VH number — which carries commercial general liability insurance of at least $500,000 per occurrence and a written contract for any job over $500. Every company in the table above holds an active registration, and the table says which of them publish it. Whether a given roofing job falls inside the Act is a question for the state, not for this guide; what we publish is the record we ran.

Why do so few roofers work out of these three towns?

Warren, Watchung and Green Brook hold 192 active home improvement registrations between them, and three of the companies in this guide are registered inside them. That is not unusual for a residential market of this kind — most of Somerset County’s roofers are clustered around Bridgewater, Branchburg and Somerville, ten to fifteen minutes west, and they drive. A full roof replacement is a scheduled job rather than an emergency call, so the distance matters less than most homeowners assume. What is worth asking directly is whether the crew on your roof works for the company or for a subcontractor, and who owns the warranty if the company changes hands.

Why does the registered name not match the company name?

Because registration attaches to a legal entity and trading names are free to differ from it. A company that was renamed, that was acquired, that operates a brand distinct from the corporation behind it, or that is a franchise location of a larger operator will show a registered name that looks unfamiliar. Nine companies in this guide do. It is normal, and it is why searching the state registry by the name on your estimate often returns nothing at all.

A roofer’s site says it serves “Warren” — is that this Warren?

Not always, and this is the single most common error in the market. Warren Township is in Somerset County. Warren County is a different place sixty miles north-west, on the Delaware. Several contractors list “Warren” in a string of county names, which means the county; several others list Warren as a town, which means the township. Where a site lists it alongside Hunterdon, Morris and Sussex it is the county; where it lists it alongside Watchung, Bridgewater and Basking Ridge it is the township. We separated the two before building the table, and where a company’s claim was to the county we did not treat it as a claim to the town.

What does GAF Master Elite actually mean?

It is the top tier of GAF’s contractor programme, restricted by the manufacturer to a limited share of roofing contractors in each area, and it requires proof of licensing where applicable, insurance and ongoing installation training. Its practical consequence for a homeowner is access to GAF’s longest workmanship warranties, which cannot be offered by a non-certified installer. Below it sit GAF Certified Plus and GAF Certified, which most of the companies here hold. Owens Corning Platinum Preferred and CertainTeed SELECT ShingleMaster are the equivalent top tiers in those two programmes. All are checkable in the manufacturer’s own contractor directory.

Who Governs Roofing Work in Warren, Watchung and Green Brook, NJ

Roofing work in New Jersey answers to two state agencies with confusingly similar names, and they do different things. The registration — the 13VH number in the table above — is issued by the Division of Consumer Affairs, Regulated Business Section — (973) 504-6370 — which is where the registration check described above is run. The permit belongs to the Uniform Construction Code, N.J.A.C. 5:23, written by the Department of Community Affairs, Division of Codes and Standards — (609) 292-7899 — and enforced by each municipality’s own construction office, listed below. New Jersey adopted the 2024 editions of its construction subcodes on August 17, 2026; the one- and two-family dwelling subcode is the International Residential Code 2024, New Jersey edition (N.J.A.C. 5:23-3.21), per the Division’s current-codes table.

Every office above was opened and read on September 4, 2026. Names are published only where the municipality publishes them.

Warren Township publishes an office and an address but no names and no direct number; parts of the township’s site would not open to us, so the row says so rather than guessing. Green Brook publishes its building inspection hours separately from its office hours — building inspections Monday to Friday, 8:00am to 2:00pm — and Watchung publishes inspection windows by trade rather than a single counter time.

Fee schedules are adopted by ordinance and change. Whether a particular job needs a permit is interpreted by the town’s own construction office, not by us. We publish what each municipality published, with the date we checked it — confirm with the office before you rely on it, and if any of it has changed, the correction address at the foot of this page is the fastest way to tell us.

Something out of date?

This guide is maintained. If anything here is wrong or has changed — a name, an address, a registration number, a certification, or whether a business has closed — tell us and we will check it. Businesses listed here are welcome to write in directly, and a company that publishes a registration number we have recorded as absent is exactly the kind of correction we want.

And if you run a roofing company that should be on this list and is not, write to us. We would rather be told than be incomplete. The test is the same one every company here cleared: that you install, repair or replace residential roofs for homeowners in Warren, Watchung or Green Brook, and that you publish that work as a service on your own website. A permit pulled in one of those municipalities, a completed job, or your registration will do it. Show us that and you go on the page.
