Not required

Required

No permit is needed under state law to reroof a detached one- or two-family house; a townhouse, other attached dwelling or any other building needs one. The Hardyston Township Building Department, Hardyston Municipal Building, 149 Wheatsworth Road, Hardyston, 973-823-7020 ext. 9001, [email protected], open "Monday through Friday 8:30 am to 4:30 pm," issues those permits for Hardyston and also for four neighbours: "The Town of Newton has contracted with Hardyston Township for Construction Department services"; in the Borough of Franklin "The Building/Construction Department is serviced by Hardyston Township"; "Hamburg Borough has entered a shared service agreement with Hardyston Township for the Construction/Building Department"; and "Sussex Borough has a shared service agreement with Hardyston Township for running the Building/Construction Department," with "All checks must be made payable to Hardyston Township." The Department of Community Affairs' municipal roster (as of September 2, 2026) still lists Sussex Borough at the Wantage Township office, 888 Route 23, Wantage, 973-875-7195. Where a roof permit is required, each municipality's own fee ordinance prices it. Hardyston, Section 88-2B(5): "The fee for a permit to re-roof or re-side an existing structure of Use Group R-3, R-4 or R-5 shall be $75," and "The minimum construction permit fee shall be $65." Newton, Section 100-16A(1)(e): "The fee for a permit to reroof an existing structure shall be $58 for all structures in Use Group R-3 or R-5 and $10 per $1,000 of the estimated cost of the work for all other use groups, with a minimum fee of $65." Franklin's fee schedule, Section 119-4, lists "Roofing/siding" at $46. Hamburg, Section 98-3, Schedule A, lists "Roof" at $24 "Per $1,000 of estimated cost" and, for "Use Groups R3 and R4 (single-family homes)," a "$50 flat fee." Sussex, Section 24-1.2, lists "Roof" at $20 "Per $1,000 of estimated cost" and, for "Use Group R3 and R4 (single family homes)," a "$65 (flat fee)." Applications for minor work, fee payments, inspection requests and permit records are handled through Hardyston's online portal (Fast Track Gov); inspection requests may also be emailed to [email protected].

The 2024 International Residential Code, New Jersey edition, adopted by the State, with the Rehabilitation Subcode for work on existing buildings. New Jersey has one construction code, the Uniform Construction Code (N.J.A.C. 5:23), which every municipality enforces; municipalities do not adopt building codes of their own (N.J.S.A. 52:27D-123.1 and 52:27D-139). N.J.A.C. 5:23-3.21(a)1 adopts the International Code Council's "2024 International Residential Code known as the IRC/2024 as the one- and two-family dwelling subcode in New Jersey subject to the modifications stated at (c) below," and 3.21(b) applies it to "detached one- and two-family dwellings and townhouses not more than three stories above grade plane in height." The section was rewritten by R.2026 d.086, "effective August 17, 2026," in the Department of Community Affairs' print of the rules "adopted and published through the New Jersey Register, Vol. 58 No. 16," and the Department's Current Construction Codes page lists the "International Residential Code/2024, NJ ed" with an adoption date of Aug 17, 2026. Other buildings fall under the building subcode, the International Building Code/2024, NJ edition (N.J.A.C. 5:23-3.14). Roof work on an existing building is held to the Rehabilitation Subcode: "Existing structures, when repaired, renovated, altered or reconstructed, shall conform to the requirements of N.J.A.C. 5:23-6, Rehabilitation Subcode" (N.J.A.C. 5:23-2.4(a)). A six-month grace period follows the adoption. N.J.A.C. 5:23-1.6(a): "For a period of six months following the operative date of a subcode revision, applicants may submit a complete permit application, including all prior approvals, to be reviewed under the code in force immediately preceding the subcode revision." The rule history gives R.2026 d.086 no date other than its effective date, so on that reading the window runs from August 17, 2026 until about February 17, 2027: a complete application filed inside it may be reviewed under either the prior edition or the 2024 edition, at the applicant's choice, and one filed after it closes is reviewed under the 2024 edition. Everything above is New Jersey state law, the same in every municipality. Locally, Hardyston's undated handout How to Obtain a Building Permit still says "All plans must be in accordance with the 2009 International Building & International Residential Codes New Jersey Editions." The Building Department page read on October 2, 2026 names no edition, and neither do the Newton, Franklin, Hamburg and Sussex construction pages that send permit work to Hardyston.

Not required — No mid-roof inspection under state law. Reroofing a detached one- or two-family house is ordinary maintenance, and N.J.A.C. 5:23-2.7(c) says "No permit for, inspections of, or notice to the enforcing agency of ordinary maintenance shall be required." Where a reroof does need a permit, N.J.A.C. 5:23-2.18(b)1 says "Inspections of one- and two-family dwellings for which construction must cease until the inspection is made shall be limited to the following": footing trenches, foundations, utility services and a mid-point inspection, whose building item is "All structural framing, connections, wall and roof sheathing, and insulation." The list names no roof-covering or underlayment stage, and the rule does not say whether its sheathing item reaches a permitted reroof that replaces sheathing. Any further inspection a municipality requires "shall be of the type and nature that construction may continue without interruption" (5:23-2.18(b)3). Everything above is New Jersey state law, the same in every municipality. Locally, Hardyston's handout How to Obtain a Building Permit, written for additions, garages and dormers, lists footing, backfill, slab, rough electric and plumbing, frame, insulation and final inspections and names no roofing inspection; the Building Department page states nothing further on roof inspections.

Not required — No impact-resistant roofing requirement under state law. The New Jersey Uniform Construction Code rules that reach a house reroof (the administrative rules in N.J.A.C. 5:23-1 and 5:23-2, the State's amendments to the 2024 International Residential Code at 5:23-3.21, and the Rehabilitation Subcode at 5:23-6) contain no UL 2218, Class 4 or hail-impact requirement for roof coverings. A municipality cannot add one: N.J.S.A. 52:27D-123.1 says "Any law or regulation to the contrary notwithstanding," the "alteration, renovation, rehabilitation, repair, maintenance, removal, or demolition of all buildings or structures already erected shall be regulated pursuant to the 'State Uniform Construction Code Act,'" and under 52:27D-139 local construction regulations were "deemed repealed and superseded" once the state code was promulgated. An owner may still choose an impact-rated roof covering. Everything above is New Jersey state law, the same in every municipality. The Hardyston Building Department page, its permit handout and Chapter 62 of the Township Code state nothing further on roof covering ratings.

No permit and no size limit for reroofing a detached one- or two-family house; a permit for every other building. N.J.A.C. 5:23-2.7(c) lists items that "are ordinary maintenance and shall be treated as such by every enforcing agency" and says "No permit for, inspections of, or notice to the enforcing agency of ordinary maintenance shall be required." Item 1.x is "The repair or replacement of existing roof covering on detached one- and two-family dwellings," with no square-footage or percentage cap. N.J.A.C. 5:23-2.14(b)1 carries this into the permit rule: "Ordinary maintenance as defined in N.J.A.C. 5:23-2.7 shall not require a permit or notice to the enforcing agency." Two limits apply. First, the item covers only detached one- and two-family dwellings. Reroofing a townhouse or other attached dwelling, or any other building, falls under the general permit rule, N.J.A.C. 5:23-2.14(a): "It shall be unlawful to construct, enlarge, repair, renovate, alter, reconstruct or demolish a structure ... without first filing an application with the construction official." Some of that work may be "minor work" under N.J.A.C. 5:23-2.17A, which still needs a permit, but "work may proceed, upon notice to the enforcing agency, before the permit is issued" (5:23-2.14(b)2). The fee is municipal: "The municipality, in accordance with this chapter, shall establish by ordinance enforcing agency fees" (N.J.A.C. 5:23-2.25; fee standards at 5:23-4.18). Second, ordinary maintenance does not include "Any work affecting structural or fire safety" (5:23-2.7(b)4), so roof work that reaches rafters, trusses or other structure needs a permit even on a detached house. The rule does not say whether replacing roof sheathing alone is such work. Everything above is New Jersey state law, the same in every municipality. Locally, the Hardyston Building Department page says "Prior to beginning any construction work on your home property, please call for permit requirements," and Hamburg's construction page carries the same line. The Town of Newton's Permits page states the general rule that a building permit is "Required whenever a building structure, regulated by the code is erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted, or demolished" and names no roof work. All five municipalities' fee ordinances price a roofing permit for the case where one is required (see the permit process note); none of them says which reroofs need one. Hardyston's Chapter 62, Building Construction, has no provision on roofing.

Two layers maximum, by state rule. Roof work on an existing building is held to the Rehabilitation Subcode (N.J.A.C. 5:23-2.4(a)), whose repair section, N.J.A.C. 5:23-6.4(e)7, reads: "Existing roof covering shall be removed before installing new roof covering when any of the following conditions occur: i. The existing roof or roof covering is water soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base for additional roofing; ii. The existing roof covering is wood shake, slate, clay, cement or asbestos-cement tile; or iii. The existing roof has two or more applications of any type of roof covering." So one existing layer of asphalt shingles may be covered once; a roof that already has two layers, a wet or deteriorated roof, or a wood shake, slate, clay, cement or asbestos-cement tile roof must be torn off first. The answer is the same if a reroof is treated as renovation rather than repair: for work other than repair, N.J.A.C. 5:23-6.8(h)7 applies "All of Chapter 9 entitled 'Roof Assemblies', except Section R907" of the 2024 International Residential Code, and its reroofing section, R908.4, Exceptions, bars a recover "Where the existing roof has two or more applications of any type of roof covering." New Jersey's Chapter 9 amendments at N.J.A.C. 5:23-3.21(c)8 change only R903.4.1 and R905.1.2 and leave R908 as published. Everything above is New Jersey state law, the same in every municipality. The Hardyston Building Department page, its permit handout and Chapter 62 of the Township Code state nothing further on roofing layers.

6.625% New Jersey Sales Tax; whether the roofing bill is taxed depends on the job. The Division of Taxation's guide Contractors and New Jersey Taxes (S&U-3, Rev. 5/25) refers to "New Jersey's 6.625% Sales Tax rate." A new roof is an exempt capital improvement: "New roof" is on the guide's list of "Exempt capital improvements," and "If the work results in an exempt capital improvement to real property, the contractor does not charge Sales Tax on the bill"; the owner gives the contractor a Certificate of Exempt Capital Improvement (Form ST-8). The roofer still pays tax on materials: "The contractor pays the Sales Tax on the cost of materials and supplies at the time of purchase." A repair is taxable. The guide lists "Fixing a leaky roof" among repairs and says "replacing a few loose bath tiles or a portion of a leaky roof is a repair to the existing real property. However, replacing all of the tiles or the entire roof with upgraded or improved materials would be an exempt capital improvement." On a taxable job the only deduction is a separately stated cost of materials, and "If the contractor does not itemize the materials and the labor for a taxable job, the entire receipt is subject to tax." Work for an exempt organization, a government agency or a qualified business in an Urban Enterprise Zone follows separate exemption rules. Everything above is New Jersey state law, the same in every municipality. The Hardyston Building Department page states nothing further on sales tax.
