At a glance
Which New Jersey counties do we serve?
We serve ten counties, six in central New Jersey and at the shore and four in the north. The table sums up the details that change a roof, window or gutter plan from one county to the next.
| County | County seat | Energy code zone | ENERGY STAR window zone | What we watch for |
|---|---|---|---|---|
| Middlesex | New Brunswick | 4A | North-Central | Raritan Bay salt air, intense downpours |
| Somerset | Somerville | 5A | Northern | Snow load, ice at the eaves |
| Monmouth | Freehold Borough | 4A | North-Central | Ocean and tidal river salt air, coastal storms |
| Mercer | Trenton | 4A | North-Central | Princeton historic districts, attached homes |
| Morris | Morristown | 5A | Northern | 35 psf fallback snow load |
| Hunterdon | Flemington | 5A | Northern | Snow load, rural homes and outbuildings |
| Essex | Newark | 4A | North-Central | Closely built older homes, attached housing |
| Passaic | Paterson | 5A | Northern | 40 psf fallback snow load |
| Ocean | Toms River | 4A | North-Central | Salt spray, wind, barrier islands |
| Sussex | Newton | 5A | Northern | Code-required ice barrier, 50 psf fallback snow load |
Energy code zones come from NJ DCA Bulletin 22-1. Window zones come from the ENERGY STAR climate zone finder. Every county name links to its own page.
Central counties
Central New Jersey: Middlesex, Somerset, Mercer and Hunterdon
These four counties sit inland of the ocean, but they straddle two energy code zones. That means the right window and the right snow detailing change as you head north and west.
Middlesex County has its seat in New Brunswick and counted 863,162 residents in the 2020 Census. Perth Amboy, South Amboy and the Laurence Harbor shore of Old Bridge face Raritan Bay. There, Sheffield Metals lists a typical 800-foot Galvalume warranty exclusion for a large bay. NOAA’s Atlas 14 puts a 10-year, 5-minute downpour at New Brunswick near 6.3 inches per hour, so gutter size matters here.
Somerset County is governed from Somerville. It falls in energy zone 5A and the ENERGY STAR Northern window zone. When the state’s hazard tools return a case study result, DCA Bulletin 19-1 lets designers use a 30 psf ground snow load for Somerset.
Mercer County is run from Trenton, the county seat. Princeton has designated 21 historic preservation overlay districts, and its commission adopted new design guidelines in September 2026. A roof or siding change there can involve a review. Mercer also moved from zone 5A to 4A when New Jersey adopted its 2021-based codes.
Hunterdon County, seated in Flemington, is the smallest county we serve by population, with 128,947 residents in the 2020 Census. QuickFacts shows an owner-occupied housing rate of 85.1 percent there. Bulletin 19-1 gives Hunterdon the same 35 psf snow fallback as Morris, so winter detailing comes first.
Shore counties
Shore counties: Monmouth and Ocean
Along the shore, salt air picks the metal before you pick a color. Several panel makers exclude Galvalume from their warranties near salt water, so the distance from your house to the ocean, bay or marsh comes first.
Monmouth County has its seat in Freehold Borough and a shoreline that runs from the Raritan Bayshore down to Manasquan. During Sandy in 2012, the National Weather Service recorded water at Sandy Hook 8.9 feet above ground level before the tide gauge failed. Metal Sales does not warrant its Galvalume panels within 1,500 feet of salt water.
Ocean County, seated in Toms River, grew from 637,229 residents in 2020 to an estimated 673,746 in 2025, about 5.7 percent, per Census QuickFacts. Sandy cut two new inlets through the barrier island near Mantoloking. The highest gust in the Mount Holly forecast area, 89 mph, was measured at Surf City. For island and bayfront homes, we start by reading the salt-water terms in the panel warranty.
Northern counties
Northern counties: Morris, Essex, Passaic and Sussex
Snow and ice drive most roof decisions up north. In Sussex County the code itself gets stricter.
Morris County has its seat in Morristown, which has a seven-member Historic Preservation Commission that advises its land use boards when asked. Bulletin 19-1 sets a 35 psf snow fallback for the county. Morris sits in zone 5A and the Northern window zone, where ENERGY STAR wants a U-factor of 0.22 or lower.
Essex County, seated in Newark, counted 863,728 residents in 2020 and an estimated 896,379 in 2025. It is in energy zone 4A and the North-Central window zone. Many older Essex neighborhoods have closely built and attached homes. An attached home generally needs a permit for a new roof, even where a detached house next door would not.
Passaic County is run from Paterson. Census QuickFacts puts its owner-occupied housing rate at 53.1 percent, which means close to half of its occupied homes are rentals. The county’s 40 psf snow fallback in Bulletin 19-1 is the second-highest value the bulletin lists, after Sussex.
Sussex County, seated in Newton, is the only place in New Jersey where the code requires an ice barrier under the roofing, per DCA Bulletin 07-3. Its 50 psf snow fallback is the highest in Bulletin 19-1. The State Climatologist puts average snowfall in New Jersey’s northern zone at 40 to 50 inches a year.
Local differences
What changes from one county to the next?
Four things change the most: the metal near salt water, snow and ice details, the window rating, and which local office reviews the work.
- Salt water. Near the ocean, bays and marshes, Galvalume warranties often stop at set distances, so aluminum or a coast-rated finish comes into play.
- Snow and ice. Fallback snow loads climb from 30 psf in Somerset to 50 psf in Sussex, the one county where code requires an ice barrier.
- Windows. The five 5A counties are in ENERGY STAR’s Northern zone, with a 0.22 U-factor limit. The five 4A counties are North-Central, at 0.25.
- Local review. State code exempts most detached-house roof and siding work from permits. Historic districts, zoning and associations stay local.
Our pages on standing seam roofs, gutters, siding and windows go deeper on each choice. If you would rather stay with shingles, see our roofing page.
Permits
Do permit rules change from town to town?
The rules are statewide, but the offices are local. New Jersey’s Uniform Construction Code applies in every municipality, and each town’s construction official enforces it.
State rules (N.J.A.C. 5:23-2.7) list a new roof covering on a detached one- or two-family home as ordinary maintenance, along with new siding on one- and two-family homes. Townhouses and other attached homes are not on that list and generally need a permit. Polypropylene siding and structural repairs fall outside the exemption too.
Local approvals still apply. A town with a historic preservation ordinance can review exterior changes in its districts, as the New Jersey Historic Trust explains. If your street may be in one, tell us at the estimate visit so the review is planned in. Our guide to roof permits in New Jersey has more.
Every county
How does a job run, wherever you live?
The same way in all ten counties: a measured visit, a written estimate, a signed contract, and a walk-through when the work is done.
State law, N.J.S.A. 56:8-151, requires a signed, written contract for any home improvement over $500, and you may cancel until midnight of the third business day after you get your copy.
Every contract includes our written workmanship warranty; see the warranty page and our process page.
Outside the map
What if your home is outside these ten counties?
Ask us. Send the address and what you need, and you will get a straight answer on whether the job fits our travel range and schedule. If we cannot give your house the care it needs, we will say so.
Neighboring counties such as Union, Bergen, Warren, Burlington and Hudson touch our area. Use the contact page or the form below, and include your town.
Coming next
Will there be pages for individual towns?
Yes, as jobs finish. We add a town page or a project case study only after we complete real work there, with photos and details from that job.
A town page should show work we actually did there. Until then, the county pages carry the local details, and the towns they list are places we serve, not past projects.

Questions
Service area questions
How far does your service area reach?
Ten counties. In central New Jersey and at the shore: Middlesex, Somerset, Monmouth, Mercer, Hunterdon and Ocean. In the north: Morris, Essex, Passaic and Sussex.
Will you look at a job just outside those counties?
Yes. Send the address and a short note on the work, and we will tell you honestly whether the trip makes sense before booking a visit.
Does my county change which metal roof you suggest?
Often, yes. Near salt water we read the panel maker’s warranty first, because Metal Sales excludes Galvalume within 1,500 feet of salt water. In the snowier northern counties, the seam type, snow guards and gutter hangers get more attention.
Is an ice and water membrane required where I live?
By code, only in Sussex County, according to NJ DCA Bulletin 07-3. We lay an eave membrane under our metal roofs in all ten counties anyway, since ice dams can form on any house that leaks heat into a cold attic.
Who issues a permit when a job needs one?
The construction office in your municipality. The Uniform Construction Code is statewide, but each town enforces it. A detached one- or two-family home usually needs no permit for a new roof or siding, while townhouses and other attached homes generally do.
Which ENERGY STAR window zone covers my county?
Somerset, Morris, Hunterdon, Passaic and Sussex are in the Northern zone, where certified windows need a U-factor of 0.22 or lower. Middlesex, Monmouth, Mercer, Essex and Ocean are North-Central, where the limit is 0.25.
