Yes, a permit is required to replace a roof in Plymouth Township (Montgomery County), PA, issued by Plymouth Township - Code Enforcement Department. Plymouth Township's Code Enforcement Department exempts roof replacement only up to 25% of the roof in a year. The Code Enforcement Department's sheet "When is a permit required?" (read October 7, 2026, https://www.plymouthtownship.org/?wpfb_dl=540), repeated in its Residential Code Package (revised 04/2022), lists the residential work "considered ordinary repairs and that do not require a permit from Plymouth Township"; the only roof entry is "Replacement of existing roof material that does not exceed 25% of the total roof area performed within any 12-month period," and the list ends: "Any work not listed above requires the appropriate permit from Plymouth Township." A full reroof exceeds that 25% line. The Township Code names no roof work outside the Historic District. Section 5-7 changes the state regulation's residential permit exemptions, deleting Section 403.62(c)(1)(i), (iii), (iv) and (xvii) and rewriting others; those subsections are cited at an earlier numbering of the regulation, and this record has not read the text they deleted. Section 5-5(a) keeps in force Township building code ordinances "adopted by the Township on or before July 1, 1999, which equal or exceed the requirements of the Code"; the Code does not list them and they were not read. In the Historic District, Chapter 7 of the Township Code says "The Building Inspector shall not issue a building permit for any erection, alteration, reconstruction, repair, restoration or demolition of all or part of any building in the District until Township Council has issued a COA," and lets the Building Inspector approve a "minor project" without referring it to the Township's historic review board; a minor project includes "replacing a roof with like materials on a noncontributing building or structure." Under state law, Act 45 says the Act "shall not apply to" "Alterations to residential buildings which do not make structural changes or changes to means of egress, except as might be required by ordinances in effect pursuant to section 303(b)(1) or adopted pursuant to section 503" or to "Repairs to residential buildings, except as might be required by ordinances in effect pursuant to section 303(b)(1) or adopted pursuant to section 503" (section 104(b)(5) and (6)), and of a municipal ordinance that adds to the code, section 503(c) says "An ordinance under this subsection shall not be effective nor enforceable unless subsections (d), (e), (f), (g), (h) and (i) have been satisfied." This record does not decide whether the municipality's requirement is one adopted under section 503 or kept in effect by section 303(b)(1). The Department of Labor and Industry's register of municipal code change ordinances lists one Plymouth Township filing, which "Establishes installation and inspection requirements for small wind energy, geothermal heating / cooling and photovoltaic systems," found in compliance with an approval letter mailed April 5, 2011 and enacted May 9, 2011, with the note "Ordinance challenged on 6 / 8 / 11." In practice, expect the Township to require a building permit for a reroof that replaces more than a quarter of the roof in a year; the Township's pages state no penalty for working without one. Applications are made on the Township's Building Permit Application or through its online permit portal, and the Residential Code Package says "A copy of the signed contract MUST accompany ALL permit applications." Section 5-11 of the Township Code requires contractors to register with the Code Enforcement Department, except those registered with the Attorney General's Bureau of Consumer Protection, who provide proof of that registration. "There is a 48 hour notice for all inspections." The department's telephone is 610-277-4103; its hours are 7:30 am to 4:15 pm, Monday through Friday. Read for this answer: Chapter 5 of the Township Code (Buildings and Building Regulation), Article I in full and Article II, Division 3 (floodplain conservation districts), and Chapter 7 (Historic District) in full; a search of the whole Township Code for "roof" and for "reroofing," which finds roof text only in the Historic District chapter and in zoning, building-numbering and other non-permit provisions; the Code Enforcement page, its permit portal page and document lists, the "When is a permit required?" sheet, the Residential Code Package and the Building Permit Application.
