Roofing in West Mifflin, Pennsylvania

No, West Mifflin, PA does not require a permit for like-for-like roof replacement (Borough of West Mifflin - Community Development Department). West Mifflin Borough's Community Development department says a building permit is not required for a residential roof replacement "if only the shingles are replaced"; its answer does not speak to other roof coverings or to replacing roof sheathing, and Chapter 135 of the Borough Code, its floodplain ordinance, has a permit of its own. The department's Application for Small Projects (read October 7, 2026), under PERMIT REQUIREMENTS, says "RESIDENTIAL ROOF REPLACEMENT: Building permit is not required if only the shingles are replaced." The same list requires a building permit for decks, foundation repair, gazebos, steps and storage sheds; its answer names shingles and does not speak to other roof coverings or to replacing roof sheathing. Chapter 100 of the Borough Code, the Borough's Uniform Construction Code ordinance, names no roof work either way: for residential permits it adopts the State's own permit section, 34 Pa. Code 403.62, adding only that the owner and contractor must make sure any required permit is obtained and posted, and it has no clause of its own on house repairs. The Borough's 2026 Fee Schedule prices building permits for "New Construction, Addition(s), Garages, Swimming Pools, Decks, Patios, Porches, Electrical" by value of construction and has no roofing line; Chapter 116 keeps the fee schedule "on file in the office of the Borough Manager." Chapter 135, Flood Damage Prevention, the Borough's floodplain ordinance, has a permit of its own from the Borough's Floodplain Administrator: "A permit shall be required before any construction or development is undertaken within any area of the Borough of West Mifflin," and "A permit shall not be required for minor repairs to existing buildings or structures." The enacted text names no roof work either way; the no-permit line is the department's stated practice, and this record does not decide whether it is the department'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 100 of the Borough Code, Construction Codes, Uniform, in full, which is the Borough's Uniform Construction Code ordinance and its building permit provisions; Chapter 116, Fee Schedule; Chapter 135, Flood Damage Prevention; Chapter 94, Buildings, Unsafe; Chapter 186, Occupancy Permits; Chapter 205, Property Maintenance; every page of a search of the whole Borough Code for "roof," which found no permit provision naming roof work; the department's Community Development and Permit Applications & Guides pages; the Application for Residential Permit; the Application for Small Projects; the Commercial Plan Review Information sheet; and the 2026 Fee Schedule. Work that does need a building permit is applied for with two plot plans and two sets of plans, building permits are priced by value of construction plus the $4.50 State fee, and under Chapter 100 anyone who starts work before obtaining a required permit pays an additional fee "equal to the fee which should have been paid at permit application." The department is open Monday through Friday, 8 am to 4 pm, at 412-466-8170.

Roofing permits & building code in West Mifflin

Roofing permit and contractor-licensing rules in West Mifflin are set locally by Borough of West Mifflin - Community Development Department. 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, West Mifflin Borough administers the code itself through its Community Development department, at 1020 Lebanon Road: the department's page says "It is through this department that permits for building construction and renovation, occupancy, grading, and signs are submitted, reviewed, and approved," and Chapter 100 of the Borough Code gives the Borough's Building Code Official and Construction Code Official the issuing of permits. The Borough sends commercial plans to Middle Department Inspection Agency for review, and plumbing is administered by the Allegheny County Health Department. Section 100-5 of the Borough Code fills in Table R301.2(1) of the 2006 International Residential Code, including "Ground snow load: 30 pounds per square foot" and "Ice shield underlayment required: yes," and Chapter 100 changes nothing in the code's roofing provisions. Chapter 100 of the Borough Code adopts "the International Residential Code/2006" and the other 2006 codes as the building codes of the Borough, the department's Application for Residential Permit says "the International Residential Code 2006 Edition will apply," and its Application for Small Projects says "For all detached single family accessory structures, the International Residential Code 2018 Edition apply"; this record has not read the 2006 or 2018 edition's text and does not decide which edition the Borough applies.
