What we find on Harmony roofs.
Housing here dates to 1966 at the median, across roughly 1,062 units. Something like 69% went up before 1980.
Roofs from this period step up and down across the house, so a single home can carry three or four separate planes meeting walls. Done properly, those junctions stop being a maintenance item; done with sealant, they come back every few years.
Lots out here are large and tree cover is heavy, so two things show up repeatedly: shaded north slopes that hold moss and algae, and limb damage after storms.
With around 2,517 people spread across 24 square miles, properties here sit far apart — long driveways, mature trees and plenty of room to work. The town sits at around 686 feet, high enough that winter arrives earlier here than it does at the shore. Harmony has been its own township since 1839. It was carved out of Greenwich Township.
What Harmony weather does to a house
This is Warren County: farmland and ridges along the Delaware, with winters closer to Pennsylvania's than the shore's. This is the high, cold corner of New Jersey. Under New Jersey's construction code Warren County is designed for 35 pounds per square foot of ground snow, among the highest figures in the state. The weight itself is rarely the problem; the problem is meltwater refreezing at a cold eave and backing up under the shingles. The fix is not a bigger gutter; it is ice-and-water shield carried well past the interior wall line, and a ventilated attic that keeps the deck cold.

“Honest about everything. They showed up on time, kept the property clean, and the roof came out amazing. Made everything stress free.”
Straight answers.
Roofing in Harmony typically runs $9,000 to $22,000. What moves a given house within that band is size, pitch and what is already on the roof — and with a median build year of 1966 and 69% of the stock built before 1980, Harmony sees more of that variation than a newer town would. The inspection settles it before you get a number.
You do, and we take care of it. Permits for a roof come from the Harmony construction office under the state Uniform Construction Code, and we pull the permit, schedule the inspection and meet the inspector ourselves.
It does. Warren County carries a design ground snow load of 35 pounds per square foot under New Jersey's construction code — among the highest in the state. In practice that means ice-and-water shield carried well up the eaves and a properly ventilated attic, because ice dams, not the weight itself, are what damage homes here.
Most residential roofs are torn off and replaced in a single day — crews start early, strip, dry-in and finish the same afternoon. Harmony is about 52 miles from our Manalapan base, well inside the area our crews cover daily.
It is a real factor. At around 686 feet, Harmony is exposed enough that damage shows up at the edges — lifted tabs along the rakes and ridge caps that let go first. We use high-wind nailing patterns and sealed ridge details as standard here.
No deposit, in Harmony or anywhere else we work. Nothing is due until the job is finished and you have walked it with us. Financing is available if you would rather spread the cost, and it does not change the quoted price.
We are a veteran-owned NJ contractor — HIC 13VH12437000, GAF-certified, 4.9 stars from 264 reviews — working throughout Warren County, including Lopatcong, White and Phillipsburg. You pay nothing up front and the quoted number is the number.
