Roof Replacement in New Jersey

Roof replacement in NJ, done as a full system

A roof replacement is one of the biggest investments you will make in your home, and most of the work is invisible from the ground. A new roof in NJ is a system: a sound deck, synthetic underlayment, a self-adhering leak barrier at the eaves and in the valleys, starter strip, the shingles themselves, ridge cap, flashing at every wall and chimney, and balanced attic ventilation. We install all of it, not just the layer you can see.

Every job starts with a full tear-off. Stripping the roof to the deck is the only way to see and replace rotted sheathing, to put leak barrier where it belongs, and to get full warranty coverage. Reroofing over existing shingles is cheaper on day one, but it hides the deck, adds weight and shortens the life of the new roof, and under the building code a roof that already has two layers has to be stripped anyway.

Most New Jersey homes get architectural shingles: a thicker, dimensional asphalt shingle rated for about 25 to 30 years, and the best value for the money on a typical asphalt shingle roof. Basic 3-tab shingles cost less but carry a shorter life, so the savings rarely pay off. Impact-resistant shingles, built to take hail better, are an option worth pricing if you want a heavier shingle. You can try colors and styles on a home like yours with our shingle color visualizer before you choose. Slate, tile and flat sections are priced as their own systems: see slate and tile roofing and flat roofs.

Most asphalt roof replacements on a typical New Jersey home take one to two days; larger or steeper roofs with a lot of valleys can run three to five. Every full replacement needs a construction permit under the New Jersey Uniform Construction Code, and we pull it with your town, schedule the inspections and include the fee in your price. More in our guide to roof permits in New Jersey.

On a typical New Jersey home, an architectural asphalt roof replacement runs roughly $9,000–$22,000, or about $450–$750 per square (100 square feet of roof) installed. Size, pitch, the number of layers to tear off and how cut-up the roof is move you within that range. Our new roof cost guide for NJ explains each factor, and our roof replacement cost calculator measures your roof from satellite to get you started.

And if your roof is not actually finished, we will say so. A targeted roof repair on a sound roof is often the better spend, and our guide to the signs you need a new roof helps you tell the difference.
