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

Adopted code

West Goshen Township - Code Enforcement

Yes, a permit is required to replace a roof in Township of West Goshen, PA, issued by West Goshen Township - Code Enforcement. West Goshen Township's code office treats roof replacement beyond a small repair as permit work. The Township's Residential Code Package and Inspection Requirements (read October 7, 2026), under "When is a permit required?", says "An ordinary repair does not require a permit" and "The following list of residential work is considered ordinary repairs and that does not require a permit from West Goshen Township," and that list includes "Replacement of existing roof material that does not exceed 25% of the total roof area performed within any 12-month period." The Township's Fee Schedule - 2026 (effective January 5, 2026) lists under Residential Building Permit "Re-Roofing (Non-Structural)" at $100, beside a separate line for "Structural Roof Changes (requires engineered plans)," and the residential permit application's Type of Work boxes include one marked Roof. A reroof of more than 25% of the roof in 12 months is outside the no-permit list. Chapters 28 and 32 of the Township Code name no roof work either way. 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). In practice, expect the Township to require a permit for a reroof of more than 25% of the roof area in 12 months. The Fee Schedule says "SHOULD ANY WORK REQUIRING A PERMIT BEGIN WITHOUT OBTAINING AN APPROVED PERMIT FROM THE TOWNSHIP, ALL PERMIT FEES WILL AUTOMATICALLY DOUBLE," and Section 32-3.H sets a fine of "not less than $100 and not more than $1,000" for building in violation of the code. A residential permit fee is "calculated at 1.5% of the actual cost of construction, with a minimum fee," plus a $4.50 State fee, and "A fee with no established minimum depicts a flat fee." The Township's FAQ says a building permit needs a completed application, two site plans, two construction drawings and proof of workers' compensation, allows "15 days for approval or denial of a residential permit," and says "24 hours notice is required for any inspections." Read for this answer: Chapter 32 of the Township Code, Construction Codes, Uniform, and Chapter 28, Building Code (Article II, Residential Code), in full; Chapter 29, Buildings, Existing; Chapter 63, Property Maintenance; a search of the whole Township Code for "roof" and for "reroofing," which found no permit provision naming roof work; the Code Enforcement page and its building permit FAQ; the Residential Code Package and Inspection Requirements; and the Fee Schedule - 2026. The Township Building is open Monday through Thursday, 7 am to 5 pm, and Fridays by appointment, at 610-696-5266.

Permit process note
West Goshen Township's code office treats roof replacement beyond a small repair as permit work. The Township's Residential Code Package and Inspection Requirements (read October 7, 2026), under "When is a permit required?", says "An ordinary repair does not require a permit" and "The following list of residential work is considered ordinary repairs and that does not require a permit from West Goshen Township," and that list includes "Replacement of existing roof material that does not exceed 25% of the total roof area performed within any 12-month period." The Township's Fee Schedule - 2026 (effective January 5, 2026) lists under Residential Building Permit "Re-Roofing (Non-Structural)" at $100, beside a separate line for "Structural Roof Changes (requires engineered plans)," and the residential permit application's Type of Work boxes include one marked Roof. A reroof of more than 25% of the roof in 12 months is outside the no-permit list. Chapters 28 and 32 of the Township Code name no roof work either way. 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). In practice, expect the Township to require a permit for a reroof of more than 25% of the roof area in 12 months. The Fee Schedule says "SHOULD ANY WORK REQUIRING A PERMIT BEGIN WITHOUT OBTAINING AN APPROVED PERMIT FROM THE TOWNSHIP, ALL PERMIT FEES WILL AUTOMATICALLY DOUBLE," and Section 32-3.H sets a fine of "not less than $100 and not more than $1,000" for building in violation of the code.

Read for this answer: Chapter 32 of the Township Code, Construction Codes, Uniform, and Chapter 28, Building Code (Article II, Residential Code), in full; Chapter 29, Buildings, Existing; Chapter 63, Property Maintenance; a search of the whole Township Code for "roof" and for "reroofing," which found no permit provision naming roof work; the Code Enforcement page and its building permit FAQ; the Residential Code Package and Inspection Requirements; and the Fee Schedule - 2026. The Township Building is open Monday through Thursday, 7 am to 5 pm, and Fridays by appointment, at 610-696-5266.
Adopted 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 Goshen Township administers the code itself: Section 32-1 of the Township Code says "The Township hereby elects to administer and enforce the Act and the regulations promulgated under the Act," Section 32-4 says "The Building Code shall be administered and enforced by the Building Code Official who shall be appointed by resolution of the Board of Supervisors," and the Township's Code Enforcement office at 1025 Paoli Pike, West Chester, takes the residential building permit applications. Section 28-7 fills in the design data of Table R301.2(1), including ice shield underlayment required, "Yes," and neither Chapter 28 nor Chapter 32 changes the code's roofing provisions. Section 32-2 of the Township Code adopts the "International Building Code, 2003 Edition," and Section 28-6 the "International Residential Code, 2003 Edition," each "as now and as hereafter supplemented, reissued, amended and revised," while the Township's Residential Code Package lists among "the current codes enforced by West Goshen Township" the "International Residential Code, 2018" and the "International Existing Building Code, 2018"; this record has not read the 2003 or 2018 editions' text.
Repair permit threshold
West Goshen Township exempts only small roof replacements from its permit and charges a re-roofing fee. The Township's Residential Code Package and Inspection Requirements (read October 7, 2026), under "When is a permit required?", says "An ordinary repair does not require a permit" and "The following list of residential work is considered ordinary repairs and that does not require a permit from West Goshen Township," and that list includes "Replacement of existing roof material that does not exceed 25% of the total roof area performed within any 12-month period." The Township's Fee Schedule - 2026 (effective January 5, 2026) lists under Residential Building Permit "Re-Roofing (Non-Structural)" at $100, beside a separate line for "Structural Roof Changes (requires engineered plans)," and the residential permit application's Type of Work boxes include one marked Roof. A reroof of more than 25% of the roof in 12 months is outside the no-permit list. 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). 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, West Goshen Township administers the code itself: Section 32-1 of the Township Code says "The Township hereby elects to administer and enforce the Act and the regulations promulgated under the Act," Section 32-4 says "The Building Code shall be administered and enforced by the Building Code Official who shall be appointed by resolution of the Board of Supervisors," and the Township's Code Enforcement office at 1025 Paoli Pike, West Chester, takes the residential building permit applications. The Township's threshold is the 25% line in its permit package quoted at the start; Chapters 28 and 32 of the Township Code set none of their own for roof work.
Roof layer limit / recover
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, West Goshen Township administers the code itself: Section 32-1 of the Township Code says "The Township hereby elects to administer and enforce the Act and the regulations promulgated under the Act," Section 32-4 says "The Building Code shall be administered and enforced by the Building Code Official who shall be appointed by resolution of the Board of Supervisors," and the Township's Code Enforcement office at 1025 Paoli Pike, West Chester, takes the residential building permit applications. Chapters 28 and 32 of the Township Code change nothing in the code's reroofing provisions, and the Township's pages say nothing on roof layers. Section 32-2 of the Township Code adopts the "International Building Code, 2003 Edition," and Section 28-6 the "International Residential Code, 2003 Edition," each "as now and as hereafter supplemented, reissued, amended and revised," while the Township's Residential Code Package lists among "the current codes enforced by West Goshen Township" the "International Residential Code, 2018" and the "International Existing Building Code, 2018"; the text above is the 2021 edition's, and the 2003 and 2018 editions' reroofing text was not read for this record.
Deck & sheathing requirements
State rules from the base code, where the state code reaches the job. Pennsylvania adopts the 2021 International Residential Code without changing Section R803, Roof Sheathing (34 Pa. Code 403.21(a)(7); the State's changes to Chapter 8 are to ridge framing and attic ventilation). Lumber roof sheathing follows Table R803.1: over rafters or beams 24 inches apart it must be at least 5/8 inch net thick. Wood structural panels "shall be identified for grade, bond classification and performance category by a grade mark or certificate of inspection issued by an approved agency," and their spans "shall not exceed the values set forth in Table R503.2.1.1(1) or APA E30." For shingles, "Asphalt shingles shall be fastened to solidly sheathed decks" (R905.2.1), and on any reroof "The structural roof components shall be capable of supporting the roof covering system and the material and equipment loads that will be encountered during installation of the roof covering system" (R908.2). 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)). Act 45 section 104(b)(5) excludes alterations "which do not make structural changes or changes to means of egress" and says only that "a structural change does not include a minor framing change needed to replace existing windows or doors"; 34 Pa. Code 403.62(d)(2) lists "The removal or cutting of any structural beam or load-bearing support" as not an ordinary repair. Neither names roof sheathing; this record does not decide whether replacing it is either. Everything above is Pennsylvania state law, the same in every municipality. Locally, West Goshen Township administers the code itself: Section 32-1 of the Township Code says "The Township hereby elects to administer and enforce the Act and the regulations promulgated under the Act," Section 32-4 says "The Building Code shall be administered and enforced by the Building Code Official who shall be appointed by resolution of the Board of Supervisors," and the Township's Code Enforcement office at 1025 Paoli Pike, West Chester, takes the residential building permit applications. Chapters 28 and 32 of the Township Code change nothing in the code's roof sheathing provisions. The Township's permit package lists "The removal or cutting of any structural beam or load-bearing support" among work that is not an ordinary repair, and its 2026 Fee Schedule prices "Re-Roofing (Non-Structural)" apart from "Structural Roof Changes (requires engineered plans)"; neither draws a separate line for roof sheathing. Section 32-2 of the Township Code adopts the "International Building Code, 2003 Edition," and Section 28-6 the "International Residential Code, 2003 Edition," each "as now and as hereafter supplemented, reissued, amended and revised," while the Township's Residential Code Package lists among "the current codes enforced by West Goshen Township" the "International Residential Code, 2018" and the "International Existing Building Code, 2018"; the text above is the 2021 edition's, and the 2003 and 2018 editions' sheathing text was not read for this record.
Sales & use tax
6% Pennsylvania sales and use tax, with a local tax added on purchases made in Allegheny County (1%) and Philadelphia (2%). On a reroof the roofer pays the tax on the materials and does not add it to the homeowner's bill. The Department of Revenue says: "The Pennsylvania sales tax rate is 6 percent. By law, a 1 percent local tax is added to purchases made in Allegheny County, and 2 percent local tax is added to purchases made in Philadelphia." Roof work is a construction activity: the rule's list of items "presumed to become a permanent part of real estate" includes "Roofing (repairs)" (61 Pa. Code 31.11). For construction activities, "A contractor shall pay tax upon the purchase price ... of all property, including materials, equipment, components and supplies, which he furnishes and installs" (61 Pa. Code 31.12(a)(1)), and the rule's example says the contractor "does not charge sales tax on this transaction to his customer. The contractor may include the tax he must pay in his bid proposal but not as a separately stated item." Apart from limited exceptions set out in the rule, the same holds on jobs for tax-exempt owners: "a contractor erecting a building, repairing a roof, replacing a door for a governmental agency, ... school district, charitable or religious organization, and the like, shall pay tax upon the property which he consumes" (61 Pa. Code 31.13(a)). Everything above is Pennsylvania state law, the same in every municipality. West Goshen Township is in Chester County. The Township's pages, permit package and Fee Schedule say nothing on sales tax.

West Goshen Township's Code Enforcement office, at 1025 Paoli Pike, West Chester, issues building permits; its residential permit package exempts only replacement of up to 25% of a roof in 12 months, and its 2026 fee schedule has a re-roofing fee. The Pennsylvania Uniform Construction Code applies statewide, but Act 45 section 104(b) lists "Repairs to residential buildings" and alterations that make no structural or egress change among work it 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."

Roofing questions: Township of West Goshen, PA

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

Yes, a permit is required to replace a roof in Township of West Goshen, PA. West Goshen Township exempts only small roof replacements from its permit and charges a re-roofing fee. The Township's Residential Code Package and Inspection Requirements (read October 7, 2026), under "When is a permit required?", says "An ordinary repair does not require a permit" and "The following list of residential work is considered ordinary repairs and that does not require a permit from West Goshen Township," and that list includes "Replacement of existing roof material that does not exceed 25% of the total roof area performed within any 12-month period." The Township's Fee Schedule - 2026 (effective January 5, 2026) lists under Residential Building Permit "Re-Roofing (Non-Structural)" at $100, beside a separate line for "Structural Roof Changes (requires engineered plans)," and the residential permit application's Type of Work boxes include one marked Roof. A reroof of more than 25% of the roof in 12 months is outside the no-permit list. 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). 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, West Goshen Township administers the code itself: Section 32-1 of the Township Code says "The Township hereby elects to administer and enforce the Act and the regulations promulgated under the Act," Section 32-4 says "The Building Code shall be administered and enforced by the Building Code Official who shall be appointed by resolution of the Board of Supervisors," and the Township's Code Enforcement office at 1025 Paoli Pike, West Chester, takes the residential building permit applications. The Township's threshold is the 25% line in its permit package quoted at the start; Chapters 28 and 32 of the Township Code set none of their own for roof work.

Can you roof over an existing roof in Township of West Goshen, 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, West Goshen Township administers the code itself: Section 32-1 of the Township Code says "The Township hereby elects to administer and enforce the Act and the regulations promulgated under the Act," Section 32-4 says "The Building Code shall be administered and enforced by the Building Code Official who shall be appointed by resolution of the Board of Supervisors," and the Township's Code Enforcement office at 1025 Paoli Pike, West Chester, takes the residential building permit applications. Chapters 28 and 32 of the Township Code change nothing in the code's reroofing provisions, and the Township's pages say nothing on roof layers. Section 32-2 of the Township Code adopts the "International Building Code, 2003 Edition," and Section 28-6 the "International Residential Code, 2003 Edition," each "as now and as hereafter supplemented, reissued, amended and revised," while the Township's Residential Code Package lists among "the current codes enforced by West Goshen Township" the "International Residential Code, 2018" and the "International Existing Building Code, 2018"; the text above is the 2021 edition's, and the 2003 and 2018 editions' reroofing text was not read for this record.

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

Yes.

What building code does Township of West Goshen, 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, West Goshen Township administers the code itself: Section 32-1 of the Township Code says "The Township hereby elects to administer and enforce the Act and the regulations promulgated under the Act," Section 32-4 says "The Building Code shall be administered and enforced by the Building Code Official who shall be appointed by resolution of the Board of Supervisors," and the Township's Code Enforcement office at 1025 Paoli Pike, West Chester, takes the residential building permit applications. Section 28-7 fills in the design data of Table R301.2(1), including ice shield underlayment required, "Yes," and neither Chapter 28 nor Chapter 32 changes the code's roofing provisions. Section 32-2 of the Township Code adopts the "International Building Code, 2003 Edition," and Section 28-6 the "International Residential Code, 2003 Edition," each "as now and as hereafter supplemented, reissued, amended and revised," while the Township's Residential Code Package lists among "the current codes enforced by West Goshen Township" the "International Residential Code, 2018" and the "International Existing Building Code, 2018"; this record has not read the 2003 or 2018 editions' text.
