Roofing in Kennett Township (Chester County), Pennsylvania

No, Kennett Township (Chester County), PA does not require a permit for like-for-like roof replacement (Kennett Township - Building and Zoning Permits). Kennett Township's Roofing Permits sheet says "NO PERMIT is required for:" "Residential Roof replacement or repair with no structural changes." The Township's Roofing Permits sheet, posted on its Forms & Permits page (read October 9, 2026), says "NO PERMIT is required for:" "Residential Roof replacement or repair with no structural changes," "Residential Roof replacement that includes gutters, wrapping, flashing, vent replacement" and "Residential Roofing that is removing all layers of existing roofing and plywood and adding a new roof," and that "PERMITS ARE required for:" "Residential roofing replacement with structural changes such as adding dormers, skylights, sun tunnels, chimneys" and "Commercial roof replacement." It closes with "Please email us with any questions or for permit forms." Chapter 93 names no roof work either way and adds no permit clause of its own; it keeps in force building code ordinances adopted on or before July 1, 1999 that equal or exceed the code, and the Township Code holds no other building code chapter. The Township's 2026 fee schedule (Resolution 2026-3) has one roofing line, "Re-roofing – commercial," at $250, and prices residential alterations by the cost of construction. The enacted text names no roof work on houses either way; the no-permit line is the Township's stated practice, and this record does not decide whether it is the Township's reading of the State's exclusion for house repairs. 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." Read for this answer: Chapter 93 of the Township Code, Construction Codes, Uniform (Sections 93-1 to 93-7), and Ordinance No. 150, in full; every hit of a search of the whole Township Code for "roof" and for "reroofing," which found no permit provision naming roof work; Chapter 168, Property Maintenance; the Forms & Permits page, the Roofing Permits sheet and the single-family permit packet; and the 2026 fee schedule, Resolution 2026-3, in full. Where a permit is needed, the 2026 fee schedule charges "2x permit fees" for "Work started without permit (unauthorized)." The Township's permit packet says appointments to drop off application packets are "Monday- Thursday 9:00 am- 4:00 pm," by phone at 610-388-1300, extension 110.

Roofing permits & building code in Kennett Township (Chester County)

Roofing permit and contractor-licensing rules in Kennett Township (Chester County) are set locally by Kennett Township - Building and Zoning Permits. Pennsylvania issues no state roofing licence, but its Home Improvement Consumer Protection Act requires a contractor to register with the Attorney General’s Bureau of Consumer Protection before doing home improvement work, which the Act defines to include roofs on jobs over $500, unless the contractor’s home improvement work totalled less than $5,000 in the previous tax year — and the Uniform Construction Code applies to buildings throughout the Commonwealth as a minimum a municipality may exceed but not fall below, with ordinary repairs to a house outside it unless a local ordinance brings them in, so whether a reroof needs a permit is a municipal question — always confirm the current requirements with the authority before starting work.

Required
Adopted building code
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, Kennett Township in Chester County administers the code through a consultant: Chapter 93 of the Township Code (Ordinance No. 150, April 19, 2004) elects to administer and enforce the Pennsylvania Construction Code Act, adopts the Uniform Construction Code "as amended from time to time" as the municipal building code, and says administration and enforcement "shall be undertaken by the designation of a consultant to serve as the municipal code official," and the Township's consultants page names Keystone Municipal Services as its "Building Codes Official / Building Inspections" firm. Permit applications go to the Township at 801 Burrows Run Road, Chadds Ford. Chapter 93 changes nothing in the code's roofing provisions. The Township's single-family permit packet says "CODES HAVE CHANGED-PLANS MUST REFERENCE THE 2021 IRC."
