What drives the cost

• Roof area: Fixr says NJ residential roofs range from about 1,000 to 4,000 sq ft, and cost scales with area times the installed per-sq-ft rate. (Fixr)
• Shingle grade: Fixr's NJ installed range is $3-$7 per sq ft for asphalt shingles and $7-$15 for architectural shingles. (Fixr)
• Tear-off: removing the old roof averages about $1 per sq ft plus disposal. Fixr says a roof-over is generally not recommended in NJ and can be done only once. (Fixr)
• Decking repair: if sheathing must be replaced, Fixr lists $0.43-$1.80 per sq ft for materials plus $1-$3 per sq ft for labor. (Fixr)
• Pitch and complexity: steep roofs (over 8/12), valleys, skylights and other penetrations add labor. The CVV benchmark includes custom flashing at two skylights. (Fixr; CVV 2025 project spec: Roofing Replacement, Asphalt Shingles)

New Jersey rules and costs

Under the NJ Uniform Construction Code, repairing or replacing the existing roof covering on a detached one- or two-family dwelling is 'ordinary maintenance' that needs no permit or notice to the construction official (N.J.A.C. 5:23-2.7(c)1.x). The exemption does not cover work affecting structural elements, and the rule's text names only detached dwellings, so attached homes and structural deck repairs should be checked with your town's construction office. Where a permit is required, the municipal construction office issues it and sets fees by local ordinance (N.J.A.C. 5:23-4.17). Code compliance still applies without a permit. Fixr's NJ guide says tear-off averages about $1 per sq ft plus disposal. (N.J.A.C. 5:23-2.7 Ordinary maintenance; N.J.A.C. 5:23-4.17 Municipal enforcing agency fees; Fixr)

How to get accurate, comparable quotes

1. Get the roof measured in squares (100 sq ft each) and make sure every bid uses the same number of squares.
2. Specify the shingle line (3-tab vs. architectural), underlayment and ice-and-water barrier, drip edge, flashing and ridge-vent details in writing.
3. Ask for a per-sheet or per-sq-ft price for replacing rotted decking, since its extent is unknown until tear-off.
4. Confirm full tear-off versus overlay, and that disposal and dumpster costs are included.
5. Ask whether your home is detached (roof covering replacement is ordinary maintenance under the UCC) or attached, and whether any structural work will need a permit.
6. Compare manufacturer warranty tiers and the contractor's own workmanship warranty, not just price.
