Roofing in Centerville, 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, Centerville Borough's office at 100 East End Road, Brownsville (724-785-9206, Monday to Friday, 8:00 to 4:00) says on its Zoning page "Building Permits are required under the Uniform Construction Code as adopted by the Commonwealth of Pennsylvania. Building Permits, construction inspections, and final Occupancy Permits are issued on behalf of the Borough by our Third Party Construction Code Official," and its About page says the Borough "has engaged a third party firm to provide this permitting and inspection service." The Borough's Ordinance No. 01-04 (ordained June 29, 2004, a scanned document read from its page images) elects to administer and enforce the Construction Code Act and adopts "The Uniform Construction Code, contained in 34 Pa. Code, Chapters 401-405, as amended from time to time," as the municipal building code. The Borough's pages and ordinances read name no code edition.
