Who’s the best siding company in South Jersey?
Our vetted pick is M&J Roofing & Siding — a family-owned contractor with offices in Blackwood and Turnersville, working across South Jersey since 2007. They’re the only company on this page we’ve independently verified, and their New Jersey registration is 13VH12363400, which you can look up yourself in about a minute.
Four other established South Jersey siding companies are listed further down with their real license numbers. We haven’t vetted those — and nobody pays us for a spot on this page.
Search “siding companies in South Jersey” and you get a wall of companies calling themselves the best, a Yelp page, and a Reddit thread. None of them tell you the one thing that actually matters before you hand someone a deposit: whether the company is currently registered with the State of New Jersey.
So that’s where we start. Every company named on this page has its real NJ home-improvement registration number printed next to it, pulled from state and BBB records. One company we looked at got cut because its license reads inactive. Here’s the list, what separates a siding crew that lasts from one that doesn’t down here, and how to run the check yourself in 60 seconds.
1. M&J Roofing & Siding — our vetted pick
M&J Roofing & Siding is the siding contractor we point South Jersey homeowners to first. It’s a family-owned company run by Michael Iannelli, operating since 2007 out of two Camden and Gloucester County offices — Blackwood and Turnersville — and it carries GAF Master Elite certification, a tier fewer than 3% of U.S. contractors reach. On the siding side they install vinyl, wood, and fiber cement, and because they’re a roofing company too, they handle the roof-to-wall flashing details where most siding jobs actually fail.

How we vet a South Jersey siding contractor
We check three things before any contractor gets into our directory, and you can run the same checks yourself in about a minute. Every New Jersey home-improvement contractor is required to register with the NJ Division of Consumer Affairs and carry a registration number beginning with “13VH,” plus commercial general liability insurance. Look any company up at njconsumeraffairs.gov/hic.
- Active 13VH registration — confirmed on the state lookup, not just claimed in a website footer. Registration has to be renewed annually, and plenty lapse.
- Real insurance and workers’ comp — so a fall off a ladder against your house isn’t your problem.
- Reputation and manufacturer certification — genuine local reviews plus credentials like GAF Master Elite or James Hardie Elite Preferred.
While putting this page together we looked at a Berlin-area siding company whose New Jersey registration comes back inactive — while its site still advertises siding work across South Jersey. We left it off. That phrase is typed by the same person who typed the rest of the marketing copy. The state database is the only thing that settles it, and it’s free.

Which siding material actually holds up in South Jersey
The right siding here depends on how far you are from the water. A vinyl job that lasts thirty years in Medford can look chalked and brittle in twelve on a barrier island, because salt air and constant UV are a different environment than the Pinelands. Here’s how the common materials behave in our conditions.
| Material | How it does down here | Best fit |
|---|---|---|
| Vinyl | Handles freeze-thaw well and won’t rot. Can warp near grills and reflected heat, and fades faster with heavy salt and sun exposure. | Inland Camden, Burlington & Gloucester County homes |
| Insulated vinyl | Same durability plus a real insulation gain — noticeable on older uninsulated walls and through humid July. | Pre-1970 housing stock in Collingswood, Haddonfield, Audubon |
| Fiber cement | The strongest performer in salt air and wind-driven rain. Won’t melt, rot, or feed insects. Heavy, so installation quality matters more. | Shore and barrier-island homes — Ocean City, Margate, Avalon |
| Wood / cedar | Looks right on historic homes but our humidity and freeze-thaw cycle mean real upkeep — sealing and repainting on a schedule. | Historic districts where the look is the point |
Most homeowners assume siding is cosmetic and skips the permit office. Under the New Jersey Uniform Construction Code, a full siding replacement generally requires a building permit, and your township may want it filed before work starts. A registered contractor pulls that permit in their name. If someone asks you to pull it, that’s a signal they may not be properly registered. In flood-zone shore towns, expect extra scrutiny around wall openings and flood vents.
Before you sign with any siding company
Get three written quotes with the same scope, and make sure each one specifies the material brand and line, not just “vinyl siding.” Ask what happens if the crew opens the wall and finds rot or old sheathing damage — a good contractor tells you the per-sheet price up front instead of surprising you mid-job. And ask for the 13VH number before the estimate, not after: a registered company gives it up without hesitating.

Frequently asked questions
Who is the best siding company in South Jersey?
Our vetted pick is M&J Roofing & Siding, a family-owned GAF Master Elite contractor in Blackwood and Turnersville working across South Jersey since 2007, NJ registration 13VH12363400. It’s the only company on this page we’ve independently verified for registration, insurance and reputation.
How do I check if a South Jersey siding contractor is licensed?
Search the company name or its “13VH” number at njconsumeraffairs.gov/hic, and confirm the registration reads active. Then ask for current certificates of general liability and workers’ compensation insurance. If a contractor can’t produce all three, walk away.
Do I need a permit to replace siding in New Jersey?
Generally yes. A full siding replacement typically requires a building permit under the New Jersey Uniform Construction Code, and your registered contractor should pull it in their own name. Fees and requirements vary by township, and flood-zone shore towns often add review steps.
What siding is best for a shore house?
Fiber cement generally outperforms vinyl in barrier-island conditions because it resists salt air, wind-driven rain and UV without warping or chalking. It costs more and weighs more, so installation quality matters — use a contractor with real fiber cement experience, not just vinyl.
Does South Jersey Contractors take payment for these rankings?
No. We don’t sell rankings or reviews. A contractor has to pass our vetting to be listed at all — advertising can buy visibility, never a rating that wasn’t earned.
