Yes, a permit is required to replace a roof in Darby Township (Delaware County), PA, issued by Township of Darby - License and Inspections Department (Catania Engineering). The Township of Darby lists roofs among work covered by a building permit. The Township's online permit portal (read October 9, 2026) lists "Building Permit" with the note "*Includes: Decks, Sheds, Black Top, Roofs, Patios, Fence, Demo, Dumpster, Grading/Excavating, Concrete," and the Township's fee schedule, effective June 11, 2025, lists under "PERMITS: RESIDENTIAL" "Building Permits" with the note "includes alterations, additions, repairs, sheds, patios, decks, roof's, blacktop," priced from $100.00 up to $1,000 of cost plus a $100.00 administrative application fee. The department's page says "PERMITS ARE REQUIRED FOR MOST WORK IN THE TOWNSHIP." The Township's building code amendments (Section 5-102) say "The fees for alterations, additions and repairs shall be the same as for new construction" and "The Building Inspector shall have the sole power in determining whether a fee is required for a permit or not," and a search of the whole Township Code for "roof" and "reroofing" found no provision naming a roofing permit or exemption. 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). In practice, expect the Township to require a building permit for a house reroof. Section 5-102 says that where work needing a permit "is started or proceeded with prior to obtaining same permit, the fee specified in this section of this Ordinance shall be doubled." Applications are made through the Township's online permit portal; the Licenses & Permits page says "YOU WILL BE NOTIFIED ON THE STATUS OF YOUR PERMIT WITH 7 - 14 DAYS" and "WE ARE UNABLE TO ACCEPT APPLICATIONS ON ANY KIND WITHOUT PROPER PROOF OF REGISTRATION" for a business license under Ordinance 538. The fee schedule adds the State's $4.50 Uniform Construction Code fee. The department is at 610-586-1514, 8:00 AM to 5:00 PM, and questions on the Uniform Construction Code go to Catania Engineering at 610-532-2884. Part 1 of Chapter 5 of the Township Code still adopts the "BOCA Basic National Building Code, 1996, Thirteenth Edition" with local amendments last changed in 2021, and Section 5-705 keeps in force building code ordinances adopted on or before July 1, 1999 that equal or exceed the Uniform Construction Code; this record has not read the BOCA code's text. Read for this answer: Chapter 5 of the Township Code, Code Enforcement, in full, including Part 1, Building Code, and Part 7, Uniform Construction Code; Chapter 4, Buildings, in full; every page of a search of the whole Township Code for "roof" and for "reroofing"; the License & Inspection, Licenses & Permits and permits-required pages; the online permit portal's home page; and the fee schedule effective June 11, 2025, in full.
