Roofing questions: Bethlehem, PA

Do you need a permit to replace a roof in Bethlehem, PA?

Yes, a permit is required to replace a roof in Bethlehem, PA. A reroof needs a permit in the City of Bethlehem, with no size limit. Section 1702.01(a)(8) of the City's Codified Ordinances (Article 1702 as last amended by Ord. 2025-43, passed November 18, 2025; https://www.bethlehem-pa.gov/CityOfBethlehem/media/Ordinance-PDFs/ARTICLE1702.pdf?ext=.pdf, read October 5, 2026) sets a separate permit fee for "Roof Replacement": "For replacement of roofing material of residential single-family dwellings and appurtenant structures the permit fee shall be forty-two dollars $42.00." Article 1701 (as last amended by Ord. 2026-02, passed February 3, 2026), "in accordance with section 303(b)(1) of the Act," deletes 34 Pa. Code 403.1(b)(8), (9) and (10), among them the state's exclusions for house alterations and repairs. The Bureau of Code Enforcement's Residential Frequently Asked Questions page (https://www.bethlehem-pa.gov/Community-Economic-Development/Code-Enforcement/Residential-Frequently-Asked-Questions, read October 5, 2026) says "A Building Permit is required whenever a property owner is constructing, altering, enlarging, repairing or demolishing a building, structure or tenant space," and its list under "A building permit is required for all of the following" begins with "Roofing" and "Siding." The Bureau's Application for Permit has a "Reroof" box. None of these states an area, percentage or cost below which roof work needs no permit. 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 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). The Department of Labor and Industry's register of municipal code change ordinances lists one City of Bethlehem filing, a 2022 ordinance on the 2018 International Fire Code, which the Department found not in compliance by letter mailed August 23, 2022; it lists no City filing on house repairs or alterations. 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, apart from the City's ordinances, the Bureau's pages and the register entry quoted at the start. Locally, the Bureau of Code Enforcement takes the permit applications, and the roof replacement fee above is the City's own.

Can you roof over an existing roof in Bethlehem, 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, the City of Bethlehem's Bureau of Code Enforcement takes permit applications and its inspectors inspect the work. Article 1701 of the City's Codified Ordinances (as last amended by Ord. 2026-02, passed February 3, 2026) adopts the Uniform Construction Code "as amended" and, "in accordance with section 303(b)(1) of the Act," deletes 34 Pa. Code 403.1(b)(8), (9) and (10), among them the state's exclusions for house alterations and repairs, and Article 1702 sets a permit fee for "Roof Replacement." Article 1701, read in full, amends no section of Chapter 9 or Section R803 of the International Residential Code. The Bureau's pages state nothing on roof layers. The City's Current Codes page still reads "2018 with amendments"; the text above is the 2021 edition's, and the 2018 edition's text was not read for this record.

Do roofing contractors need a license or registration in Bethlehem, PA?

Yes.

What building code does Bethlehem, 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, the City of Bethlehem's Bureau of Code Enforcement takes permit applications and its permit page says "All Inspections will be performed by City of Bethlehem Inspectors." Section 1701.01 of the City's Codified Ordinances adopts the Pennsylvania Construction Code Act and 34 Pa. Code Chapters 401 to 405, "as amended," as the official codes of the City "for the erection, construction, enlargement, alteration, repair, moving, removal, demolition, conversion, occupancy and maintenance of all buildings and structures of the City of Bethlehem providing for the issuance of permits," and Section 1701.02, "in accordance with section 303(b)(1) of the Act," deletes 34 Pa. Code 403.1(b)(8), (9) and (10), among them the state's exclusions for house alterations and repairs. Its amendments to the International Residential Code fill in Table R301.2(1) and set a plumbing depth; Article 1701, read in full, amends no section of Chapter 9 or Section R803. The Bureau's Current Codes page still reads "The UCC adopts the following codes: 2018 with amendments"; Article 1701 adopts the code "as amended," and the State's adoption of the 2021 International Residential Code, described above, took effect January 1, 2026.
