Roofing in Dublin, 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, Dublin Borough's Code of Ordinances, Section 5-101, says "This municipality hereby elects to administrator and enforce the provisions of the Pennsylvania Construction Code Act," and the Borough's Administration page lists a "Code Enforcement / Building Inspector" with a "BCO" designation, from a consulting firm, among its staff. Building permit applications are made to the Borough office at 119 Maple Avenue, Dublin (215-249-3310), and the Borough's Building & Zoning page says "A UCC fee of $4.50 is added to each building permit." Chapter 5, Part 1 of the Borough's Code (Ord. 257, June 28, 2004), read in full on ecode360, adopts "The Uniform Construction Code, contained within Title 34 Pa. Code, Chapters 401-405, as amended from time to time" as the municipal building code, keeps in force earlier ordinances "adopted by this municipality on or before July 1, 1999, and which are equal to or exceed the requirements of the Code," and in Section 5-108 amends three State provisions, one of which is "Section 403.62.(c).(1).(xvii) is deleted in its entirety." In the State regulation as published in the Pennsylvania Bulletin (volume 34, issue 2, the 2004 rulemaking), that subparagraph read "Installation of an uncovered deck where the floor of the deck is no more than 30 inches above grade," so the deletion concerns decks. Chapter 5 names no roof work either way and names no code edition. The Borough's Chapter 4 (Buildings) covers house numbering and Knox-Boxes. The Borough's pages and Chapter 5 name no code edition, adopting the Uniform Construction Code "as amended from time to time"; this record does not decide which edition the Borough applies.
