Roof Replacement Cost in NJ - 2026 Guide

Roof replacement on a typical 2,000-square-foot Ocean County home runs roughly $9,500 to $22,000 in 2026 for an Owens Corning Total Protection system. Coastal homes within a mile of the ocean trend higher because we spec stainless flashing and Duration Storm shingles to handle salt air. Designer shingles add another 30 percent on top of architectural pricing. Most installs finish in 1 to 2 working days once we are on the roof. Three days when the weather fights us. Every install is covered by a 30-year Quality Roof Pros labor warranty paired with the Owens Corning Lifetime manufacturer warranty, registered in your name during the final walkthrough. This guide breaks down what drives cost, what the Owens Corning system actually includes, and where homeowners save vs spend on a replacement in 2026.

• Roof size - measured in squares (1 square = 100 sq ft). A typical NJ home is 18-30 squares.
• Roof pitch - steeper roofs need more labor and safety setup.
• Tear-off complexity - one layer vs two-layer tear-off changes labor and dump fees.
• Shingle line - architectural (standard), Duration Storm (coastal), or designer (premium).
• Decking surprises - rotten plywood gets replaced at lumber rate plus labor. We show you before we replace.
• Coastal exposure - stainless flashing and ice and water shield extension on shore-area homes.

As an Owens Corning Platinum Preferred Contractor, we install the full system on every replacement. That isn't just shingles.

Deck: plywood inspection, replacement of rot, re-nailing where loose. Underlayment: synthetic Pro-Armor underlayment over the field, ice and water shield in valleys and at eaves. Flashing: drip edge at eaves and rakes, step flashing at sidewalls, counter-flashing at chimneys.

Shingles: Owens Corning Duration or Duration Storm depending on exposure. Ventilation: ridge vent or static vents balanced to your attic intake. Hip and ridge: OC Hip and Ridge accent shingles.

Every layer is registered for the OC Lifetime manufacturer warranty during the final walkthrough.

• Small home, 15-20 squares: $7,500 to $14,000.
• Typical home, 20-28 squares: $9,500 to $18,000.
• Larger home, 28-40 squares: $14,000 to $26,000.
• Coastal upgrade (Duration Storm + stainless flashing): add 8-15%.
• Designer shingle upgrade: add 25-35%.
• Two-layer tear-off: add $1,000 to $2,500 in labor and dump fees.

Financing options are available - ask about financing during your free inspection if a full out-of-pocket isn't realistic. We don't pressure-sell financing; we explain the options and you decide. See /financing for current programs.

Storm-driven replacements are often filed under homeowners insurance. We help document the claim with photos and a written condition report. We don't negotiate the claim with your adjuster - that's regulated work in NJ. See the NRCA homeowner storm damage resource for the documentation flow.

Save: committing to a full system once instead of patch-on-patch over five years. Picking the right shingle line for your exposure (don't pay designer pricing inland if you don't need it). Bundling related work (gutter replacement, attic ventilation) into one project.

Spend: trying to find a 30-percent discount on labor. The cheap install is the one you replace twice. Skipping ice and water shield to save a few hundred. That's the layer that pays for itself the first time water tries to back up under the eave.
