Quick Answer
How much does a roof replacement cost in New Jersey?

What Actually Drives Roof Replacement Cost
The calculator handles the big inputs. These six items decide where your final number lands, and every one of them is spelled out line by line on a Nail Force written estimate.
Roof size and pitch
Roofers price by the square, which is 100 square feet of roof surface. Your roof is usually bigger than the home’s footprint because of pitch and overhangs, and steeper roofs take more labor and safety setup.
Layers being torn off
Every old layer has to come off, get hauled away and disposed of. Two layers means more weight, more dumpster space and more labor than one. We confirm how many you have during the estimate.
Decking condition
Soft or rotted plywood under the old shingles has to be replaced before the new roof goes on. We photograph the bad spots and spell out how rotted wood is handled right on the quote.
Shingle grade
Architectural asphalt is the starting point. Premium architectural, designer shingles and synthetic slate or shake each step the price up. The right pick depends on the look you want and how long you plan to stay.
Flashing and ventilation
Step flashing, chimney flashing, pipe boots, ice and water barrier and balanced intake and exhaust ventilation are what keep a roof dry. They belong in every estimate, not tacked on after tear-off.
Valleys, dormers, skylights
A simple gable roof goes faster than a cut-up roof with valleys, dormers, skylights and several ridge lines. Every extra detail adds cutting, flashing and labor, so complexity always shows up in the price.
Honest Ways to Get More Roof for the Money
Ask if a repair will do
Not every leak means a new roof. If the shingles still have life and the damage is in one area, a repair may be the smarter call. We’ll tell you straight and show you photos of what we found.
Do roof and gutters together
If your gutters are tired, replacing them with the roof avoids a second setup and lets the drip edge, fascia and new seamless aluminum gutters get detailed together. One project, one estimate, one company to call.
Check for storm damage
If wind or hail hit your roof, part of the cost may be an insurance claim. We document the damage with photos and meet your adjuster. We can’t promise the outcome, but we’ll help you make your case.
Compare itemized quotes
A single lump-sum number hides what’s in it. Ask every roofer to list materials, tear-off, decking and flashing line by line. Then you’re comparing the same roof, not a lowball that grows once shingles come off.

If yours isn’t here, call us. You’ll get a real answer.
It’s a ballpark, not a quote. The calculator uses your roof size, pitch, layers and shingle grade, but it can’t see rotted decking, worn chimney flashing or ventilation problems. Your actual price comes from measuring and inspecting the roof, so treat the range as a starting point and call (973) 713-1053 for a free written estimate.
Start with your home’s footprint and expect the roof to be larger. Pitch and overhangs add surface area, and steeper roofs add more. If you’re not sure, set the slider near your best guess and let us measure it for free during the estimate. The exact size goes on your written quote.
Repair it if the damage is limited and the rest of the roof still has good years left. Replace it if leaks keep coming back, shingles are curling or shedding granules across the roof, or the decking is going soft. We’ll give you an honest answer with photos. See roof repairs and full roof replacement.
Everything it takes to build the roof right: tear-off and disposal, how rotted decking is handled, synthetic underlayment, ice and water barrier, flashing, ventilation, shingles, ridge cap, daily cleanup and a magnetic nail sweep. It’s written and itemized, so you see each line. A complete Owens Corning roof system is eligible for Preferred Protection coverage.
Yes, qualified homeowners can finance a roof through our financing partner. That lets you fix the roof now instead of waiting on the next leak. We don’t quote rates or terms here because they depend on your application. Get the details on our financing page or ask during your free estimate.
It might, if the damage came from a storm like wind or hail rather than age and wear. We photograph and document the damage and can meet your adjuster at the house. We can’t promise what the insurance company decides. Learn more about storm damage roofing or call (973) 713-1053.
For most homes, an architectural asphalt shingle is the best value. It looks sharp, handles New Jersey weather and costs far less than synthetic slate. We install both Owens Corning and GAF. A complete Owens Corning system from us is eligible for up to 50 years of non-prorated material coverage.
