Roofing in Macungie, 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, Macungie Borough's Borough Hall at 21 Locust Street, Macungie (610-966-2503, Monday to Friday, 8:00 am to 4:30 pm) accepts the Borough's "ZONING & UCC PERMIT APPLICATION," whose fee table has borough fee and inspection fee columns, and the Borough's Administration page lists a Zoning/Code Enforcement Officer who works for a consulting firm. Resolution 2024-10, the Borough's 2025 fee schedule, lists "Inspection Fees and Plan Review: See attached BIA Fee Schedule," and the page attached to the posted copy is a table of the consulting firm's hourly rates. The Borough's Code of Ordinances is published on American Legal Publishing's site, which answered an automated read with a security check page, and the Borough's Ordinances & Resolutions page lists no ordinance adopting the Uniform Construction Code, so the Borough's ordinance adopting the code and any permit chapter were not read for this record. The sheet's only edition reference is "International Residential Code of 2003," for coal-fired boilers, and the Borough's pages name no edition for roofing; this record has not read the 2003 edition's text and does not decide which edition the Borough applies.
