Roofing in New Castle, Pennsylvania

Required

The 2021 International Residential Code, as adopted by the State in the Pennsylvania Uniform Construction Code (UCC). 34 Pa. Code 403.21(a)(7) adopts "The 'International Residential Code of 2021,' except that:" followed by the State's list of exclusions and modifications, effective January 1, 2026 (55 Pa.B. 7701). None of the State's changes touches Chapter 9, Roof Assemblies, or Section R803, Roof Sheathing, so those apply as the International Code Council publishes them. Work on existing buildings is also pointed to the State's existing-building code: "The repair, alteration, change of occupancy, addition and relocation of existing buildings must comply with Chapter 34 of the 'International Building Code of 2021' or with the 'International Existing Building Code of 2021'" (34 Pa. Code 403.21(f)). The UCC is the minimum everywhere in the state: "no municipality may propose or enact any ordinance which is less than the minimum requirement of the Uniform Construction Code" (Pennsylvania Construction Code Act, Act 45 of 1999, section 503(b)). The Act also lists work it "shall not apply to", including "Alterations to residential buildings which do not make structural changes or changes to means of egress" or to "Repairs to residential buildings," in each case "except as might be required by ordinances" kept in force under section 303(b)(1) or adopted under section 503 (Act 45 section 104(b)(5) and (6); 34 Pa. Code 403.1(b)(8) and (9)). The Act defines a repair as "The reconstruction or renewal of any part of an existing building for the purpose of its maintenance." So whether the code's roofing rules reach a given house reroof depends on the municipality's own ordinances. Everything above is Pennsylvania state law, the same in every municipality. Locally, The City of New Castle elects to administer the code: Section 1702.03 of the City Code says "The City of New Castle hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act, Act 45 of 1999, as amended from time to time, and its regulations," and the City's Planning / Zoning page, for the office at the Municipal Building, 230 N. Jefferson St., New Castle, offers the City's Residential Construction Permit Application. Section 1702.04 lets the City act through its own code official, a third-party agency or an intermunicipal agreement "as administered by the Lawrence County Regional Council of Governments"; the City's pages read for this record do not say which it uses. Article 1702 names no code edition; the Flood Plain Management article refers to "the 2009 IBC and the 2009 IRC or latest revisions thereof," and the City's pages name no edition; this record has not read the 2009 edition's text and does not decide which edition the City applies. Article 1702 changes nothing in the code's roofing provisions.

The City of New Castle takes residential construction permit applications through its Planning / Zoning office, and the City's code and pages read for this record do not say whether a house reroof needs a permit. Article 1702 of the City Code (read October 7, 2026) adopts the Uniform Construction Code "as amended from time to time" as "the municipal building code of the City of New Castle" and adds only an expiration schedule for permits (Section 1702.08); it names no roof work and adds no permit requirement for repairs or alterations. The City's Flood Plain Management article says in Section 1709.04 "It shall be unlawful for any person, partnership, business or corporation to undertake, or cause to be undertaken, any construction or development anywhere within the City of New Castle unless a permit has been obtained from the Flood Plain Administrator" and "A permit shall not be required for minor repairs to existing buildings or structures"; Section 1709.08 makes the Zoning Officer the Floodplain Administrator, and the article defines DEVELOPMENT to include "the construction, reconstruction, renovation, repair, expansion, or alteration of buildings or other structures" and MINOR REPAIR as "The replacement of existing work with equivalent materials for the purpose of its routine maintenance and upkeep," excluding structural, egress and piping work. Whether a reroof is a minor repair under that definition is not stated by the City and is not decided here. The City's Residential Construction Permit Application (a scanned form, read from its image) asks for a description of construction and has the applicant "ACKNOWLEDGE THE SMOKE DETECTOR REQUIREMENTS INVOLVED WITH ALTERATION, REPAIR AND ADDITION PERMITS"; it names no roof work. The City publishes no permit fee schedule, permit-exemption list or roofing guidance on its pages read for this record. Under state law, Act 45 section 104(b)(5) and (6) list "Alterations to residential buildings which do not make structural changes or changes to means of egress" and "Repairs to residential buildings" among work the Act does not apply to, "except as might be required by ordinances in effect pursuant to section 303(b)(1) or adopted pursuant to section 503," and 34 Pa. Code 403.62(c) says "A permit is not required for the exceptions listed in § 403.1(b) (relating to scope) and the following, if the work does not violate a law or ordinance." This record does not state whether the City requires a permit for a house reroof; ask the Planning / Zoning office before starting. The application lists a building permit fee, a municipal fee and a $4.50 training fee, and Section 1702.08 says permits valued up to $100,000 expire at one year. Read for this answer: Title One of the City's Building and Housing Code (Article 1702, Pennsylvania Uniform Construction Code Act, and Article 1709, Flood Plain Management), in full; Title Two, Local Provisions (Articles 1725 to 1745); Title Three, Existing Structures (Article 1761, International Property Maintenance Code); a search of the whole City Code for "roof," which found no permit provision naming roof work, and for "reroofing" and "re-roof," which found none; the City's Planning / Zoning and Code Enforcement pages; and the City's Residential Construction Permit Application. The Municipal Building is open Monday to Friday, 8:30 AM to 3:30 PM; the Planning / Zoning office's telephone is 724-656-3525 and the City's main number is 724-656-3500.
