Adopted code

Borough of Chambersburg - Land Use and Community Development Department

The Borough of Chambersburg's Land Use and Community Development Department, at Borough Hall, 100 South Second Street, issues land use permits, and the Borough's third-party code agency, Pennsylvania Municipal Code Alliance (PMCA), issues Uniform Construction Code permits; the Borough's code and pages read for this record do not say whether a house reroof needs a permit. 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."

Permit process note
The Borough of Chambersburg issues a land use permit first, and its third-party agency, Pennsylvania Municipal Code Alliance (PMCA), issues Uniform Construction Code permits; the Borough's code and pages read for this record do not say whether a house reroof needs a permit. Chapter 113 of the Borough Code adopts the Uniform Construction Code "as amended from time to time" as the Municipal Building Code, requires the land use permit before a construction permit (Section 113-6 C), and names no roof work; it adds no permit requirement for repairs or alterations of its own. The Borough's Applications & Permits page lists a Land Use/Use & Occupancy permit for "Construction of buildings, additions to or remodeling of existing buildings," and names no roof work. PMCA's own website, which does not name the Borough on the pages read, answers the question "I am re-roofing my residential structure - do I need a building permit?" with a letter dated July 20, 2018 and addressed "Dear Municipal Official," which says "a residential Re-roof still requires compliance with the provisions of the UCC but does not require a building permit" and "If structural work is required such as replacing studs, headers, rafters or trusses a permit would now be required"; the letter refers to the 2015 International Residential Code. PMCA's Re-Roof Application Packet says "A Building Permit is required if there is a structural repair." The Borough's Master Fee Schedule resolution (changes of May 11, 2026) reproduces PMCA's 2026 Supplemental Fee Schedule, which lists "Residential Re-Roof" at $160 "(with structural repairs, framing & final)." The Borough's own pages say nothing on reroofing. 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." This record does not state whether the Borough requires a permit for a house reroof; ask the Land Use and Community Development Department (717-251-2417) or PMCA (717-496-4996) before starting. Section 113-5 sets a fine of "not less than $250 nor more than $1,000" for violating Chapter 113, and there is no fee for a Borough land use permit. Read for this answer: Chapter 113 of the Borough Code, Building Construction (Sections 113-1 to 113-8), in full; Chapter 221, Property Maintenance; a search of the whole Borough Code for "roof" and for "reroofing," which found no permit provision naming roof work on private property; the Borough's Land Use and Community Development and Applications & Permits pages; its 2026 Land Use Permit Application; its Master Fee Schedule resolution, including PMCA's 2026 Residential and Supplemental Fee Schedules in it; and PMCA's home, Permit Applications and FAQ pages, Re-Roof Application Packet, re-roof letter and ice barrier sheet.
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, The Borough of Chambersburg elects to administer the code (Section 113-1 of the Borough Code: "The Borough hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code, Act 45 of 1999"), and its Land Use and Community Development Department says the Uniform Construction Code "is enforced by the Borough's state-certified third party code enforcement agency, Pennsylvania Municipal Code Alliance (PMCA)." Section 113-6 C requires a Borough land use permit first: "Issuance by the Borough of a land use permit for the specific project shall be a prerequisite to make application for a construction permit." The Borough's Land Use Permit Application says the applicant must then contact PMCA, at 1013 Wayne Avenue, to obtain a "UCC Permit." Section 113-2 adopts the Uniform Construction Code, "as amended from time to time," as the Municipal Building Code of the Borough of Chambersburg. Chapter 113 of the Borough Code and the Borough's pages name no code edition; PMCA's ice barrier sheet, marked revised October 20, 2020, says "All Municipalities Served by PMCA follow and enforce the provisions of the 2018 International Residential Code (IRC)," and its re-roof letter of July 20, 2018 refers to the 2015 edition; this record has not read the 2018 or 2015 edition's text and does not decide which edition PMCA applies. Chapter 113 changes nothing in the code's roofing provisions.
Repair permit threshold
The Borough of Chambersburg's code adopts the Uniform Construction Code by reference and names no roof work; its third-party agency's published guidance says a residential re-roof needs no building permit unless structural work is involved. Chapter 113 of the Borough Code adopts the Uniform Construction Code "as amended from time to time" as the Municipal Building Code, requires the land use permit before a construction permit (Section 113-6 C), and names no roof work; it adds no permit requirement for repairs or alterations of its own. The Borough's Applications & Permits page lists a Land Use/Use & Occupancy permit for "Construction of buildings, additions to or remodeling of existing buildings," and names no roof work. PMCA's own website, which does not name the Borough on the pages read, answers the question "I am re-roofing my residential structure - do I need a building permit?" with a letter dated July 20, 2018 and addressed "Dear Municipal Official," which says "a residential Re-roof still requires compliance with the provisions of the UCC but does not require a building permit" and "If structural work is required such as replacing studs, headers, rafters or trusses a permit would now be required"; the letter refers to the 2015 International Residential Code. PMCA's Re-Roof Application Packet says "A Building Permit is required if there is a structural repair." The Borough's Master Fee Schedule resolution (changes of May 11, 2026) reproduces PMCA's 2026 Supplemental Fee Schedule, which lists "Residential Re-Roof" at $160 "(with structural repairs, framing & final)." The Borough's own pages say nothing on reroofing. 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, The Borough of Chambersburg elects to administer the code (Section 113-1 of the Borough Code: "The Borough hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code, Act 45 of 1999"), and its Land Use and Community Development Department says the Uniform Construction Code "is enforced by the Borough's state-certified third party code enforcement agency, Pennsylvania Municipal Code Alliance (PMCA)." Section 113-6 C requires a Borough land use permit first: "Issuance by the Borough of a land use permit for the specific project shall be a prerequisite to make application for a construction permit." The Borough's Land Use Permit Application says the applicant must then contact PMCA, at 1013 Wayne Avenue, to obtain a "UCC Permit." Chapter 113 of the Borough Code, quoted at the start, sets no threshold for roof work; PMCA's guidance draws its line at structural 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, The Borough of Chambersburg elects to administer the code (Section 113-1 of the Borough Code: "The Borough hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code, Act 45 of 1999"), and its Land Use and Community Development Department says the Uniform Construction Code "is enforced by the Borough's state-certified third party code enforcement agency, Pennsylvania Municipal Code Alliance (PMCA)." Section 113-6 C requires a Borough land use permit first: "Issuance by the Borough of a land use permit for the specific project shall be a prerequisite to make application for a construction permit." The Borough's Land Use Permit Application says the applicant must then contact PMCA, at 1013 Wayne Avenue, to obtain a "UCC Permit." Chapter 113 of the Borough Code changes nothing in the code's reroofing provisions, and the Borough's pages say nothing on roof layers; PMCA's re-roof letter of July 20, 2018 says "Metal roofing should not be installed over more than two layers of shingles without the authorization of a design professional." So whether a Borough ordinance brings a house reroof within the Uniform Construction Code is not stated here. Chapter 113 of the Borough Code and the Borough's pages name no code edition; PMCA's ice barrier sheet, marked revised October 20, 2020, says "All Municipalities Served by PMCA follow and enforce the provisions of the 2018 International Residential Code (IRC)," and its re-roof letter of July 20, 2018 refers to the 2015 edition; the text above is the 2021 edition's, and the 2018 and 2015 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, The Borough of Chambersburg elects to administer the code (Section 113-1 of the Borough Code: "The Borough hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code, Act 45 of 1999"), and its Land Use and Community Development Department says the Uniform Construction Code "is enforced by the Borough's state-certified third party code enforcement agency, Pennsylvania Municipal Code Alliance (PMCA)." Section 113-6 C requires a Borough land use permit first: "Issuance by the Borough of a land use permit for the specific project shall be a prerequisite to make application for a construction permit." The Borough's Land Use Permit Application says the applicant must then contact PMCA, at 1013 Wayne Avenue, to obtain a "UCC Permit." Chapter 113 of the Borough Code changes nothing in the code's roof sheathing provisions. PMCA's re-roof letter says the existing roof sheathing and rafters must be verified as sound and "free from rot or decay" and that if structural work such as replacing rafters or trusses is required a permit would be required; it draws no separate line for replacing sheathing. Chapter 113 of the Borough Code and the Borough's pages name no code edition; PMCA's ice barrier sheet, marked revised October 20, 2020, says "All Municipalities Served by PMCA follow and enforce the provisions of the 2018 International Residential Code (IRC)," and its re-roof letter of July 20, 2018 refers to the 2015 edition; the text above is the 2021 edition's, and the 2018 and 2015 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. The Borough of Chambersburg is in Franklin County. The Borough's pages and Master Fee Schedule say nothing on sales tax.

When does a roof repair need a permit in Borough of Chambersburg, PA?

The Borough of Chambersburg's code adopts the Uniform Construction Code by reference and names no roof work; its third-party agency's published guidance says a residential re-roof needs no building permit unless structural work is involved. Chapter 113 of the Borough Code adopts the Uniform Construction Code "as amended from time to time" as the Municipal Building Code, requires the land use permit before a construction permit (Section 113-6 C), and names no roof work; it adds no permit requirement for repairs or alterations of its own.

PMCA's Re-Roof Application Packet says "A Building Permit is required if there is a structural repair." The Borough's Master Fee Schedule resolution (changes of May 11, 2026) reproduces PMCA's 2026 Supplemental Fee Schedule, which lists "Residential Re-Roof" at $160 "(with structural repairs, framing & final)." The Borough's own pages say nothing on reroofing. 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.

Can you roof over an existing roof in Borough of Chambersburg, 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 Borough of Chambersburg elects to administer the code (Section 113-1 of the Borough Code: "The Borough hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code, Act 45 of 1999"), and its Land Use and Community Development Department says the Uniform Construction Code "is enforced by the Borough's state-certified third party code enforcement agency, Pennsylvania Municipal Code Alliance (PMCA)." Section 113-6 C requires a Borough land use permit first: "Issuance by the Borough of a land use permit for the specific project shall be a prerequisite to make application for a construction permit." The Borough's Land Use Permit Application says the applicant must then contact PMCA, at 1013 Wayne Avenue, to obtain a "UCC Permit." Chapter 113 of the Borough Code changes nothing in the code's reroofing provisions, and the Borough's pages say nothing on roof layers; PMCA's re-roof letter of July 20, 2018 says "Metal roofing should not be installed over more than two layers of shingles without the authorization of a design professional." So whether a Borough ordinance brings a house reroof within the Uniform Construction Code is not stated here. Chapter 113 of the Borough Code and the Borough's pages name no code edition; PMCA's ice barrier sheet, marked revised October 20, 2020, says "All Municipalities Served by PMCA follow and enforce the provisions of the 2018 International Residential Code (IRC)," and its re-roof letter of July 20, 2018 refers to the 2015 edition; the text above is the 2021 edition's, and the 2018 and 2015 editions' reroofing text was not read for this record.

Do roofing contractors need a license or registration in Borough of Chambersburg, PA?

Yes.

What building code does Borough of Chambersburg, 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 Borough of Chambersburg elects to administer the code (Section 113-1 of the Borough Code: "The Borough hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code, Act 45 of 1999"), and its Land Use and Community Development Department says the Uniform Construction Code "is enforced by the Borough's state-certified third party code enforcement agency, Pennsylvania Municipal Code Alliance (PMCA)." Section 113-6 C requires a Borough land use permit first: "Issuance by the Borough of a land use permit for the specific project shall be a prerequisite to make application for a construction permit." The Borough's Land Use Permit Application says the applicant must then contact PMCA, at 1013 Wayne Avenue, to obtain a "UCC Permit." Section 113-2 adopts the Uniform Construction Code, "as amended from time to time," as the Municipal Building Code of the Borough of Chambersburg. Chapter 113 of the Borough Code and the Borough's pages name no code edition; PMCA's ice barrier sheet, marked revised October 20, 2020, says "All Municipalities Served by PMCA follow and enforce the provisions of the 2018 International Residential Code (IRC)," and its re-roof letter of July 20, 2018 refers to the 2015 edition; this record has not read the 2018 or 2015 edition's text and does not decide which edition PMCA applies. Chapter 113 changes nothing in the code's roofing provisions.
