Roofing questions: Township of Lower Paxton, PA

When does a roof repair need a permit in Township of Lower Paxton, PA?

Lower Paxton Township states no threshold for roof work in the pages read (October 5, 2026). Its Building Permit Fees page charges fees "for construction of, additions to, or repair of any building or structure," its Building Codes page says "Please refer to the Pennsylvania Uniform Construction Code (PA UCC) PA Act 45 for all changes, exemptions, and exclusions to the adopted codes," and neither page, its FAQs nor its 2026 building permit application names roofing. Chapter 90, Article III, of its codified ordinances adopts the Uniform Construction Code by reference, has no permit clause of its own and names no roof work. Pennsylvania's Construction Code Act says it "shall not apply to" "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 in effect pursuant to section 303(b)(1) or adopted pursuant to section 503" (Act 45 section 104(b)(5) and (6)). Section 503(c) adds: "An ordinance under this subsection shall not be effective nor enforceable unless subsections (d), (e), (f), (g), (h) and (i) have been satisfied." State law sets no square-footage or percentage threshold for roof work; any threshold is set locally. The Uniform Construction Code "does not apply to" "Alterations to residential buildings which do not make structural changes or changes to means of egress, except as required by ordinances in effect under sections 303(b)(1) or 503 of the act" or to "Repairs to residential buildings, except as required by ordinances in effect under sections 303(b)(1) and 503 of the act" (34 Pa. Code 403.1(b)(8) and (9)), and "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" (34 Pa. Code 403.62(c)). For houses the regulation adds: "An ordinary repair does not require a permit." Its list of work that is not an ordinary repair names cutting away a load-bearing wall, "The removal or cutting of any structural beam or load-bearing support," changes to a required means of egress, and new or relocated piping, wiring or mechanical work (34 Pa. Code 403.62(d)); roofing is not named. A municipality may require more: under Act 45 section 503(c) it "may enact ordinances pursuant to this section which adopt additional code requirements for alterations or repairs to residential buildings," after a public hearing and after filing the proposed ordinance with the Department of Labor and Industry. These rules concern a "Residential building," which the regulation defines as "Detached one-family and two-family dwellings and townhouses which are not more than three stories above grade plane in height with a separate means of egress and their accessory structures" (34 Pa. Code 401.1). Everything above is Pennsylvania state law, the same in every municipality. Locally, Lower Paxton Township's Community Development Department takes building permit applications, and Approved Code Services, Inc. is the Township's Building Code Official. Chapter 90, Article III, of the Township's codified ordinances was read; it adopts the code by reference, has no permit clause of its own and names no roof work.

Can you roof over an existing roof in Township of Lower Paxton, PA?

Two layers at most where the state code reaches the job. Pennsylvania adopts the 2021 International Residential Code without changing its reroofing section, R908 (34 Pa. Code 403.21(a)(7); the State's list of changes names no Chapter 9 section). Section R908.3.1.1 says "A roof recover shall not be permitted where any of the following conditions occur," and the third condition is "Where the existing roof has two or more applications of any type of roof covering." So one existing layer may be covered once, and a roof that already has two layers is torn off to the deck. The same section also bars a recover "Where the existing roof or roof covering is water soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base for additional roofing" and "Where the existing roof covering is slate, clay, cement or asbestos-cement tile." The existing-building code the State also adopts, the 2021 International Existing Building Code (34 Pa. Code 403.21(f)), carries the same three conditions in Section 705.2.1.1. These rules bind work the Uniform Construction Code reaches. The Act does not apply to "Repairs to residential buildings" or to alterations that make no structural change, "except as might be required by ordinances" (Act 45 section 104(b)(5) and (6)), so whether R908 binds a particular house reroof turns on that exclusion and on the municipality's own ordinances. Everything above is Pennsylvania state law, the same in every municipality. Locally, Lower Paxton Township's Community Development Department takes building permit applications, and Approved Code Services, Inc. is the Township's Building Code Official. Chapter 90, Article III, of the Township's codified ordinances was read; it adopts the code by reference, has no permit clause of its own and names no roof work. No Township page read states a roof layer limit. The Township's Building Codes page still names the 2018 International Residential Code; the text above is the 2021 edition's, and the 2018 edition's text was not read for this record.

Do roofing contractors need a license or registration in Township of Lower Paxton, PA?

Yes.

What building code does Township of Lower Paxton, PA use?

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, Lower Paxton Township's Community Development Department takes building permit applications, and the Township's pages name Approved Code Services, Inc. of Mechanicsburg as its "Third Party Building Code Department" and its "Building Code Official (BCO)". The Township's Building Codes page still says the Township "has adopted the 2018 International Residential Codes (IRC) and the 2018 International Building Code (IBC) as of February 14, 2022" and names no later edition; it also says "Please refer to the Pennsylvania Uniform Construction Code (PA UCC) PA Act 45 for all changes, exemptions, and exclusions to the adopted codes." Chapter 90, Construction Standards, of the Township's codified ordinances was read (its table of contents and Article III in full). Article III (Ord. No. 18-06) says "The Township hereby elects to administer and enforce the provisions of the Pennsylvania 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; its only amendments set flood-map dates in the 2015 International Building Code (section 1612.3) and International Existing Building Code (section 1401.2). It has no permit clause of its own and names no roof work, and a code-wide search for "roof" found no section naming roofing as permit work or as exempt. None of the Township pages read (Community Development, Building Codes, Building Permit Fees, its FAQs and its 2026 building permit application) names roof work either. No ordinance reaching residential repairs or alterations beyond the code's own reach was found in those reads.
