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

Roofing questions: Township of Bethlehem, PA

When does a roof repair need a permit in Township of Bethlehem, PA?

Bethlehem Township publishes no area or cost threshold for roof work; its department ties the permit to the scope of the work. The department's answer to "Is a permit required for roofing?" (read October 6, 2026) is "Yes, if the work being done is more than replacing only shingles," and its Permits page lists "Reroof (commercial only)" among "Construction Permits." The Township's own residential building permit fees (fee schedule effective June 1, 2025) have no roofing line, and its Application for Building Permit has no roofing box. The Keycodes Inspection Agency's "2025 Fee Schedule – Residential Inspection Services," attached to the Township's fee schedule as Exhibit 1, lists "Roof Replacement" at "$127.00 – includes 1 site visit"; the Township's fee schedule applies that exhibit to residential work only for electrical permits and "As-Needed Third-Party Fees," and neither document says whether a reroof that replaces only shingles is work it prices. Chapter 110 of the Township Code (Sections 110-1 to 110-10, as amended February 16, 2026 by Ord. No. 03-26) adopts the Uniform Construction Code "as may be amended from time to time," has no permit clause of its own for house repairs or alterations, and names no roof work. 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." 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. Locally, Bethlehem Township administers the code through its Community Development Department with a retained inspection agency: Section 110-1 of the Township Code says the Township "hereby elects to administer and enforce the Pennsylvania Construction Code Act," the department's Permits page says it "is primarily responsible for building, zoning, and fire prevention permit review, issuance and inspection," and the Township's fee schedule prices commercial building and fire permits, electrical permits and third-party work "as needed" on the Keycodes Inspection Agency fee schedule attached to it as Exhibit 1. Neither the department nor Chapter 110 sets an area or cost threshold for roof work; the department's line is "more than replacing only shingles."

Can you roof over an existing roof in Township of 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, Bethlehem Township administers the code through its Community Development Department with a retained inspection agency: Section 110-1 of the Township Code says the Township "hereby elects to administer and enforce the Pennsylvania Construction Code Act," the department's Permits page says it "is primarily responsible for building, zoning, and fire prevention permit review, issuance and inspection," and the Township's fee schedule prices commercial building and fire permits, electrical permits and third-party work "as needed" on the Keycodes Inspection Agency fee schedule attached to it as Exhibit 1. Chapter 110 of the Township Code changes nothing in the code's reroofing provisions, and the department's pages say nothing on roof layers. The department's Permits page says the Township "adheres to the 2018 International Codes"; the text above is the 2021 edition's, and the 2018 edition's reroofing text was not read for this record.

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

Yes.

What building code does Township of 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, Bethlehem Township administers the code through its Community Development Department with a retained inspection agency: Section 110-1 of the Township Code says the Township "hereby elects to administer and enforce the Pennsylvania Construction Code Act," the department's Permits page says it "is primarily responsible for building, zoning, and fire prevention permit review, issuance and inspection," and the Township's fee schedule prices commercial building and fire permits, electrical permits and third-party work "as needed" on the Keycodes Inspection Agency fee schedule attached to it as Exhibit 1. Chapter 110 of the Township Code (Sections 110-1 to 110-10, as amended February 16, 2026 by Ord. No. 03-26) adopts the Uniform Construction Code "as may be amended from time to time," has no permit clause of its own for house repairs or alterations, and names no roof work. Section 110-3 (amended February 16, 2026 by Ord. No. 03-26) fills in Table R301.2 of "the International Residential Code of 2021" with a ground snow load of 30 psf and a wind speed of 115 mph and makes plumbing insertions; it changes nothing in the code's roofing provisions. The department's Permits page, however, says "Bethlehem Township adopted the Pennsylvania Uniform Construction Code (UCC) and adheres to the 2018 International Codes." So the department's own page names the 2018 codes while the Township Code and the State's rule name the 2021 edition; this record has not read the 2018 edition's roofing text. Section 110-7 keeps in force Township building code ordinances adopted on or before July 1, 1999 that equal or exceed the code; those older ordinances were not read.
