How much does a roof replacement cost in New Jersey?
A national cost guide puts a New Jersey roof replacement at $10,000 to $24,000 for 2,000 square feet of roof. The same guide says most homeowners in the state spend roughly $15,000.
A second national guide lists the average new roof in New Jersey at $5,500 to $15,500. Your own number depends on the size of the roof and what shows up under the old shingles. These are market numbers, not our price list. Our roof replacement service page covers how the job itself runs.
What does a new roof cost in New Jersey by roof size?
Roof estimates are often quoted by the square. One square covers 100 square feet of roof. This table comes from the first guide’s New Jersey page, which runs $5 to $12 per square foot installed.
| Roof size (square feet) | Squares | New Jersey market range |
|---|---|---|
| 1,000 | 10 | $5,000 to $12,000 |
| 1,500 | 15 | $7,500 to $18,000 |
| 2,000 | 20 | $10,000 to $24,000 |
| 3,750 | 37.5 | $18,750 to $45,000 |
Roof size and floor space are two different numbers. Both guides figure a 1,000-square-foot home carries about 1,120 square feet of roof. The New Jersey page puts that roof at $5,100 to $13,400 with mid-range materials. A two-story house has less roof than a ranch with the same floor space.
For a bigger roof, a national remodeling journal’s 2025 cost report priced a 30-square job at $31,871. That job assumed a full tear-off on a hip roof with two skylights. It is a national average, not a New Jersey price.
What moves the price of a roof replacement?
National cost guides price the common line items like this.
| Line item | Market figure |
|---|---|
| Tearing off old shingles | $1 to $2 per square foot (New Jersey page) |
| New decking, plywood or OSB | $2 to $5 per square foot installed |
| Standard asphalt shingles | $3 to $7 per square foot installed (New Jersey page) |
| Architectural asphalt shingles | $7 to $15 per square foot installed (New Jersey page) |
| A new roof vent | $200 to $700 |
| Drip edge | $1.50 to $3.00 per linear foot |
| Replacing all the flashing | $400 to $1,000 |
Old layers and tear-off
New Jersey’s rehabilitation subcode says the old roof must come off once it has two layers. It must also come off when it is water soaked or too worn to hold new roofing. Wood shake and tile roofs always come off first. One guide notes that a layover saves the removal cost but shortens the new roof’s life.
Decking
Decking is the plywood or OSB under the shingles. Rot in the decking often stays hidden until the old roof comes off. Ask for a price per sheet in writing before work starts.
Pitch and shape
One guide says pitches steeper than 6:12 need extra safety steps and more labor. Chimneys and skylights raise the cost too, the same guide says.
Shingle grade
Three-tab asphalt shingles are the entry-level option. Architectural shingles cost more and hold up better against wind, per the New Jersey page. If you are weighing another material, our metal roofing page covers that choice.
Ventilation and flashing
A quote should name the vents that go in, such as a ridge vent. One guide says most installers include new flashing in the estimate. Ask whether yours replaces the old flashing at walls and chimneys or reuses it.
Do you need a permit to replace a roof in New Jersey?
For a detached one- or two-family home, no. The state Uniform Construction Code lists the replacement of existing roof covering on those homes as ordinary maintenance. Ordinary maintenance needs no permit and no notice to the town.
Attached townhouses are not on that line, so check with the township construction office. Framing repairs fall outside the list too. If a quote for a detached house lists a permit fee, ask what work it covers.
Do you pay sales tax on a new roof in New Jersey?
Usually not on a full new roof. The New Jersey Division of Taxation lists a new roof as an exempt capital improvement. You give the contractor a completed Form ST-8. The contractor then may not collect sales tax from you on the job.
A repair is different. The state counts fixing a leaky roof as a repair, and the labor on a repair is taxable.
What should a roof replacement quote include?
Compare quotes line by line before you compare totals. A clear quote spells out these items:
- How many layers come off, and how the old roof is hauled away
- A price per sheet for any rotted decking
- The underlayment, and whether ice and water barrier goes at the eaves and valleys
- Drip edge, plus new or reused flashing
- The vents, such as a ridge vent
- The shingle line and color
- Cleanup of the yard and driveway, nails included
New Jersey’s code requires an ice barrier only where the average January day is 25 degrees or colder. The state’s code bulletin says that area is Sussex County. In South Jersey it is a choice, so one quote may include it and another may not.
When is a roof repair enough?
The first guide says a repair can make sense when the roof is fairly new and the damage is limited. That means a few shingles or a contained leak. Widespread damage or rot underneath points toward a new roof. So do repairs that keep coming back.
The second guide puts patching a small leak at $150 to $1,000. Our roof repair page covers that work. For more repair figures, read what common roof repairs cost in New Jersey.
