Do I need a permit for roof replacement in
Kearny, New Jersey?

You have a 1950s-era Kearny ranch with one layer of old three-tab shingles, no structural damage visible, and you want to install new architectural asphalt shingles (same pitch, same slope). This is a straightforward reroofing permit. Your roofer (or you, if owner-builder) files with the Kearny Building Department, submitting a roof plan showing dimensions, pitch (say, 6:12), material (Class A architectural asphalt, nails per ASME spec, fastening pattern), and underlayment detail (synthetic underlayment full coverage, ice-and-water shield from eave to 36 inches inboard per IRC R905 and NJ climate requirements). Kearny's plan reviewer will approve this in 5–7 business days; no structural review needed. You'll schedule an inspection for deck nailing and fastening (the inspector looks for proper nail spacing, correct fastener size, and verifies only one existing layer exists by spot-checking). Once that passes, you can proceed with shingle installation and flashing. Final inspection happens after all shingles, flashing, and vents are installed. Total permit timeline: 2–3 weeks from filing to final sign-off. Permit fee: approximately $150–$200 (1,800 sq. ft. ÷ 100 = 18 squares × $8–$11 per square, typical Kearny rate). No structural engineer required. Roofer removes the old layer, replaces any soft decking (if minor), installs new underlayment per spec, and installs new shingles. Work can usually be completed in 2–4 days once permit is in hand.

Your 1970s colonial in Kearny has three layers of shingles (found during contractor inspection). IRC R907.4 mandates tear-off; you cannot overlay. Your roofer pulls a tear-off-and-replace permit, and the plan reviewer flags this as 'structural roof repair' because full deck exposure is required. The permit application includes roof plan, material spec (new Class A shingles), underlayment (synthetic, ice-and-water shield per climate spec), and a note: 'Existing three layers to be removed; deck inspection and repair as needed.' Kearny's plan reviewer approves this, but the deck-nailing inspection is more thorough: the inspector (or you, under permit supervision) must expose the sheathing at multiple points to verify deck condition. If rot or soft spots are discovered (common in 50-year-old roofs, especially in damp Kearny climate), the inspector will note defective sheathing that must be replaced before new roofing is installed. This can add $500–$2,000 to the project (materials + labor for new 1/2-inch plywood sheets and nailing). Your permit fee is higher: approximately $250–$350 (elevated review category for tear-off + structural). Timeline stretches to 3–4 weeks if deck repair is needed (additional plan review for deck repair scope, then re-inspection). If no deck repair is found, timeline is 2–3 weeks as normal. The three-layer tear-off and disposal is a major labor cost ($2,000–$3,500 in removal alone); confirm the roofer has licensed waste hauling and is certified to recycle or dispose of shingles per New Jersey DEP regs (roofing waste is regulated). This scenario showcases Kearny's strict enforcement of the three-layer rule and why pre-inspection of existing layers is critical to budgeting.

Your Kearny home is near the Hackensack tidal zone (FEMA flood zone AE or X-shaded). You want to upgrade from old asphalt shingles to a new standing-seam metal roof for durability and flood resilience. This triggers a full material-change permit with structural review. Your roofer (or engineer) submits a permit application including: roof plan, specifications for metal material (gauge, paint coating, wind rating), rafter-size certification (metal roof attachment points are different from shingle attachment), and a structural engineer's letter confirming the existing framing can support the new load and attachment method. Additionally, because your property is in a flood zone, Kearny's plan reviewer will cross-reference FEMA flood maps and may require upgrading to Class A fire-rated metal, wind-resistant fasteners, and flood-resistant underlayment (per FBC guidelines that New Jersey adopts in tidal/coastal areas). The metal roof itself is lighter than asphalt, but the attachment is heavier-duty, so the structural review is non-waivable. Permit fee: $300–$400+ (structural review category, material change, flood-zone documentation). Plan review: 10–14 days (structural engineer review adds time). You'll need a structural engineer's stamp, which costs $400–$700 depending on local engineer rates. Deck inspection verifies rafter size and condition; final inspection checks metal fastening, flashing, and underlayment spec per flood-zone requirements. Timeline: 4–5 weeks from filing to final. This scenario illustrates Kearny's approach to climate-zone and flood-zone overlay requirements, which are unique to Kearny's location and would differ significantly in inland municipalities.
