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

Yes, a permit is required to replace a roof in Township of Baldwin, PA. Baldwin Township requires a permit for residential repairs and alterations, and exempts only re-roofing of less than 25% of the roof. Section 5-102.1 of the Township Code (Ord. No. 435, August 7, 2007, read October 12, 2026) requires permits for "All alterations or repairs to residential buildings which are exempt from the UCC by Act 92 of 2004," except nine listed kinds of work that "shall continue to be exempt and no permit will be required," the second of which is "Re-roofing of less the 25% of the total existing roof square footage." A full reroof is above that line. 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). The Department of Labor and Industry's register of municipal code change ordinances lists a Baldwin Township filing that "Requires a building permit for all residential alterations and repairs and establishes 9 exceptions," found "in compliance with 35 P.S. § 7210.503 (b); approval letter mailed 4 / 26 / 07," "Enacted 8 / 7 / 07." In practice, expect the Township to require a permit for a reroof of 25% or more of the roof. The record found no penalty clause in Sections 5-101 to 5-106 and did not read the Township's fee schedule, which Section 5-106 leaves to resolution. 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, Baldwin Township administers the Uniform Construction Code itself: Section 5-101 of the Township Code says "The Township of Baldwin hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the zoning chapter has the Zoning Officer "Issue zoning certificates, building permits, certificates of occupancy, sign permits, or any other permits required hereunder" (Section 27-1102) and says "Each application for a building permit shall be filed with the Zoning Officer" (Section 27-1105). The Township Municipal Building is at 10 Community Park Drive, Pittsburgh. Its threshold is the one in Section 5-102.1 quoted at the start: re-roofing of less than 25% of the total existing roof square footage needs no permit, and a larger reroof does.

Can you roof over an existing roof in Township of Baldwin, 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, Baldwin Township administers the Uniform Construction Code itself: Section 5-101 of the Township Code says "The Township of Baldwin hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the zoning chapter has the Zoning Officer "Issue zoning certificates, building permits, certificates of occupancy, sign permits, or any other permits required hereunder" (Section 27-1102) and says "Each application for a building permit shall be filed with the Zoning Officer" (Section 27-1105). The Township Municipal Building is at 10 Community Park Drive, Pittsburgh. Chapter 5 of the Township Code changes nothing in the code's reroofing provisions beyond the permit threshold quoted in the permit fields, and the Code says nothing on roof layers or a code edition.

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

Yes.

What building code does Township of Baldwin, 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, Baldwin Township administers the Uniform Construction Code itself: Section 5-101 of the Township Code says "The Township of Baldwin hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the zoning chapter has the Zoning Officer "Issue zoning certificates, building permits, certificates of occupancy, sign permits, or any other permits required hereunder" (Section 27-1102) and says "Each application for a building permit shall be filed with the Zoning Officer" (Section 27-1105). The Township Municipal Building is at 10 Community Park Drive, Pittsburgh. Section 5-102 adopts the Uniform Construction Code, "as amended from time to time," as the municipal building code, and Section 5-102.1 adds the permit requirement quoted in the permit fields. The Township's Code names no code edition for the building code.
