Roofing questions: Township of Lower Windsor, PA

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

Lower Windsor Township's Zoning/Building Permit Process sheet lists replacement roof shingles, where there is no increase in exterior dimension and no change in use, under "Residential projects that require NO permit." The Township's Zoning/Building Permit Process sheet, linked from its Zoning page, lists under "Residential projects that require NO permit" the line "Alterations and renovations when there is no increase in exterior dimension AND no change in use, including new facia, replacement siding, or roof shingles, shutters, etc." The same sheet says "Changes to the structural integrity of the house (exterior walls, floors, roof trusses, beams and the like) require a building permit" and "If you aren’t sure if a permit is required, PLEASE CALL." The sheet carries no date and was live when read on October 9, 2026. Chapter 180 of the Township Code adopts the Uniform Construction Code, "as amended from time to time," as the Township's building code and names no roof work, either as permit work or as exempt. Nothing read names residential reroofing as permit work: the 2026 general fee schedule (Resolution 2026-07) has no roofing line and sets UCC inspection fees by the Commonwealth Code fee schedule, which is not published on the Township's site, and the Application for Building/Zoning Permit has no roofing box. Under state law, Act 45 section 104(b)(5) and (6) list "Alterations to residential buildings which do not make structural changes or changes to means of egress" and "Repairs to residential buildings" among work the Act does not apply to, "except as might be required by ordinances in effect pursuant to section 303(b)(1) or adopted pursuant to section 503," and 34 Pa. Code 403.62(c) says "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." The sheet comes from the Zoning Department, which issues Zoning and Building permits on one application, while CCIS reviews and inspects building permit work; its no-permit list does not say in terms that no building permit is needed, and no CCIS statement on reroofing was found, so this record does not decide whether an ordinary reroof needs a building permit. 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 Windsor Township's Zoning Department, at 2425 Craley Road, Wrightsville, "issues all permits for Lower Windsor Township," and its Zoning page says building permits "are reviewed and construction is inspected for conformance with the PA Uniform Construction Code (UCC) by Commonwealth Code Inspection Service, Inc. (CCIS)", which "was appointed by the Board of Supervisors as the Township's third-party inspection Agency." Chapter 180 of the Township Code (Ord. No. 2004-05, effective July 1, 2004) elects to administer and enforce the Construction Code Act. The Township's sheet, quoted at the start, lists replacement roof shingles with no increase in exterior dimension and no change in use among projects that require no permit, and requires a building permit for changes to roof trusses or other structural parts of the house. Act 45 section 104(b)(5) excludes alterations "which do not make structural changes or changes to means of egress" and says only that "a structural change does not include a minor framing change needed to replace existing windows or doors"; 34 Pa. Code 403.62(d)(2) lists "The removal or cutting of any structural beam or load-bearing support" as not an ordinary repair. Neither names roof sheathing; this record does not decide whether replacing it is either.

Can you roof over an existing roof in Township of Lower Windsor, 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 Windsor Township's Zoning Department, at 2425 Craley Road, Wrightsville, "issues all permits for Lower Windsor Township," and its Zoning page says building permits "are reviewed and construction is inspected for conformance with the PA Uniform Construction Code (UCC) by Commonwealth Code Inspection Service, Inc. (CCIS)", which "was appointed by the Board of Supervisors as the Township's third-party inspection Agency." Chapter 180 of the Township Code (Ord. No. 2004-05, effective July 1, 2004) elects to administer and enforce the Construction Code Act. Chapter 180 of the Township Code changes nothing in the code's reroofing provisions, and the Township's pages say nothing on roof layers.

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

Yes.

What building code does Township of Lower Windsor, 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 Windsor Township's Zoning Department, at 2425 Craley Road, Wrightsville, "issues all permits for Lower Windsor Township," and its Zoning page says building permits "are reviewed and construction is inspected for conformance with the PA Uniform Construction Code (UCC) by Commonwealth Code Inspection Service, Inc. (CCIS)", which "was appointed by the Board of Supervisors as the Township's third-party inspection Agency." Chapter 180 of the Township Code (Ord. No. 2004-05, effective July 1, 2004) elects to administer and enforce the Construction Code Act. Section 180-2 adopts "The Uniform Construction Code, contained in 34 Pa. Code Chapters 401 to 405, as amended from time to time" as the Township's building code, Section 180-5D says that as the UCC adopts updated codes "such codes shall automatically be updated as part of this article," and Chapter 180 names no edition and changes nothing in the code's roofing provisions.
