Roofing in Harrisburg, Pennsylvania

Required

Required

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, the City of Harrisburg's Bureau of Codes administers the code; its page says "The Bureau processes all permits related to building construction and performs inspections required for building construction" and that "Effective January 1, 2026 as amended and adopted by the Commonwealth of Pennsylvania the City of Harrisburg follows the codes as set forth by the PA UCC," naming the 2021 IRC among them. Chapter 8-117 of the City's codified ordinances (Ord. No. 19-2004) says "The City of Harrisburg hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act" and adopts the Uniform Construction Code, "as amended from time to time," as the City of Harrisburg Construction Code. Chapters 8-101 (Building Code) and 8-111 (Residential Code) still adopt the 2003 International Building Code and the 2003 International Residential Code with City amendments; that 2003 base text was not read, and the Bureau's current page names the 2021 edition. Both chapters amend the code's repair exemption (105.2.2 and R105.2.2) to read: "Application or notice to the Building Official is not required for ordinary repairs to structures, replacement of lamps or the connection of approved portable electrical equipment to approved permanently installed receptacles, provided that such repairs total less than $1,000 on a single project performed within a three-month period." That enacted text names no roof work, and a code-wide search for "roof" found no section naming roofing as permit work or as exempt. The Bureau's own FAQ lists "Roofing" among work for which "Permits are required."

Harrisburg treats roofing as permit work. On its Bureau of Codes page (https://harrisburgpa.gov/services/codes/index.php, read October 5, 2026), the Bureau of Codes FAQ answers "What activity on my property requires a permit?" with "Permits are required for the following:" and lists "Roofing" without qualification, along with "Any work exceeding $1000.00," "Replacement windows and doors" and "Renovation of a residential building". Its building permit application lists "Roofing" as a type of improvement, and the codified residential code of the City limits the no-permit repair exemption to repairs that "total less than $1,000 on a single project performed within a three-month period" (Chapter 8-111, R105.2.2). 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." 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, a roofer should expect the Bureau to require a permit for a reroof, as its FAQ states; the application carries a line for a "Penalty Fee (if applicable)." After an emergency or natural disaster the FAQ says "emergency repairs or replacement of equipment may be made without first applying for a permit if a permit application is submitted to the building code official within 3 business days of the repair or replacement." The building permit application is one form covering building and zoning; the contractor and any subcontractor "must be listed and must possess a valid Mercantile License," and the FAQ says "All contractors doing work in the city of Harrisburg must have a Business Privilege License." The residential fee schedule (revised May 1, 2024) says "Plan Review and Inspections fees are based on $8.00 per $1,000," includes a $75 City application fee and the $4.50 state fee, and rounds the project cost up to the next $1,000 (a $1,000 job is $90.50). Applications may be mailed with the fees or brought to the Bureau of Codes, 10 North 2nd Street, Suite 205, Harrisburg, open Monday to Friday, 8 a.m. to 4 p.m., phone 717-255-6553. Exterior work in a historic district may need review: the FAQ says such a project "may require further review and approval by the City's Planning Bureau to assure compliance with historic standards."
