Letterkenny Township - Land Use and Building Permits

Yes, a permit is required to replace a roof in Township of Letterkenny, PA, issued by Letterkenny Township - Land Use and Building Permits. The permit a reroof needs here is Letterkenny Township's Land Use Permit, a local permit, not a Uniform Construction Code building permit: the Township's Resolution 2021-1, enacted January 4, 2021 and linked from its Permits page, amends "the following fees for issuing Land Use Permits" and lists "Roofing Material Replacement (No Structural Changes)" under "$35.00 Land Use Permits that Do Not Need Building Permits" (read Oct 12, 2026). For the Uniform Construction Code building permit, the same resolution says "Land Use Permits that Do Not Need Building Permits" for that item and lists "Roof new or with structural change" under "$70.00 - Land Use Permits that Require Building Permits (from CCIS)." The Permits page also says "A permit is not required for minor repairs to existing buildings provided that no structural changes or modifications are involved"; it names no roof work, and this record does not decide whether a reroof is a minor repair. The Township's Land Use Permit application says it is "to build, erect, or remodel a structure in Letterkenny Township" and "Application for a Building Permit will not be accepted until a Land Use Permit is issued by the Township." 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 Land Use Permit requirement is one adopted under section 503, kept in effect by section 303(b)(1), or made under the municipality's other powers. Because the Township's enacted fee resolution lists roofing material replacement as a Land Use Permit, a reroof without one risks whatever the Township imposes; the resolution states no penalty. The Land Use Permit is obtained at the township building during office hours.

Read for this answer: the Township's Permits, Ordinances and FAQs pages, its Permit Check List, its Land Use Permit application and Resolution 2021-1 in full.
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, Letterkenny Township's Permits page, read October 12, 2026, says "Residents must first obtain a Land Use Permit by visiting the township building during office hours. After receiving the Land Use Permit, you will take it to Commonwealth Code Inspection Service (CCIS) in Chambersburg to apply for the Building Permit," and the Township's Permit Check List says "Obtain Building Permit from Commonwealth Code Inspection Service (CCIS)"; the agency's office is at 1102 Sheller Ave, Chambersburg (717-262-0081). The Township office is at 4924 Orrstown Rd., Orrstown (717-532-8716), open Tuesday 8:00 am to 4:00 pm and Wednesday and Thursday 8:00 am to 2:00 pm. The Township's Ordinances page lists ordinances on junk, septic pumping, subdivision and land development and animal nuisances, and posts no building code or Uniform Construction Code adoption ordinance; the Permits page says "There is no zoning in Letterkenny Township." The Township's pages read name no code edition.
Impact-resistant roofing
Not required — No impact-resistance requirement under state law. The State's adoption of the 2021 International Residential Code (34 Pa. Code 403.21) contains no hail or impact rule, and it makes no change to the code's roof assemblies chapter, which itself has no UL 2218, Class 4 or hail-impact requirement for roof coverings. A municipality could add one only by an ordinance that equals or exceeds the Uniform Construction Code under Act 45 section 503, filed with the Department of Labor and Industry; none of the filings on the Department's register of municipal code change ordinances mentions hail or impact resistance. An owner may still choose an impact-rated roof covering. Everything above is Pennsylvania state law, the same in every municipality. Locally, Letterkenny Township's Permits page, read October 12, 2026, says "Residents must first obtain a Land Use Permit by visiting the township building during office hours. After receiving the Land Use Permit, you will take it to Commonwealth Code Inspection Service (CCIS) in Chambersburg to apply for the Building Permit," and the Township's Permit Check List says "Obtain Building Permit from Commonwealth Code Inspection Service (CCIS)"; the agency's office is at 1102 Sheller Ave, Chambersburg (717-262-0081). The Township office is at 4924 Orrstown Rd., Orrstown (717-532-8716), open Tuesday 8:00 am to 4:00 pm and Wednesday and Thursday 8:00 am to 2:00 pm. The Township's Ordinances page lists ordinances on junk, septic pumping, subdivision and land development and animal nuisances, and posts no building code or Uniform Construction Code adoption ordinance; the Permits page says "There is no zoning in Letterkenny Township." The Township's pages and Resolution 2021-1 name no impact-resistance rule.
Repair permit threshold
Letterkenny Township has its own Land Use Permit. The permit a reroof needs here is Letterkenny Township's Land Use Permit, a local permit, not a Uniform Construction Code building permit: the Township's Resolution 2021-1, enacted January 4, 2021 and linked from its Permits page, amends "the following fees for issuing Land Use Permits" and lists "Roofing Material Replacement (No Structural Changes)" under "$35.00 Land Use Permits that Do Not Need Building Permits" (read Oct 12, 2026). For the Uniform Construction Code building permit, the same resolution says "Land Use Permits that Do Not Need Building Permits" for that item and lists "Roof new or with structural change" under "$70.00 - Land Use Permits that Require Building Permits (from CCIS)." The Permits page also says "A permit is not required for minor repairs to existing buildings provided that no structural changes or modifications are involved"; it names no roof work, and this record does not decide whether a reroof is a minor repair. The Township's Land Use Permit application says it is "to build, erect, or remodel a structure in Letterkenny Township" and "Application for a Building Permit will not be accepted until a Land Use Permit is issued by the Township." 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 Land Use Permit requirement is one adopted under section 503, kept in effect by section 303(b)(1), or made under the municipality's other powers. Because the Township's enacted fee resolution lists roofing material replacement as a Land Use Permit, a reroof without one risks whatever the Township imposes; the resolution states no penalty. 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, Letterkenny Township's Permits page, read October 12, 2026, says "Residents must first obtain a Land Use Permit by visiting the township building during office hours. After receiving the Land Use Permit, you will take it to Commonwealth Code Inspection Service (CCIS) in Chambersburg to apply for the Building Permit," and the Township's Permit Check List says "Obtain Building Permit from Commonwealth Code Inspection Service (CCIS)"; the agency's office is at 1102 Sheller Ave, Chambersburg (717-262-0081). The Township office is at 4924 Orrstown Rd., Orrstown (717-532-8716), open Tuesday 8:00 am to 4:00 pm and Wednesday and Thursday 8:00 am to 2:00 pm. The Township's Resolution 2021-1 sets a Land Use Permit fee of $35.00 for roofing material replacement and sets no area or cost threshold below which none is needed.
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, Letterkenny Township's Permits page, read October 12, 2026, says "Residents must first obtain a Land Use Permit by visiting the township building during office hours. After receiving the Land Use Permit, you will take it to Commonwealth Code Inspection Service (CCIS) in Chambersburg to apply for the Building Permit," and the Township's Permit Check List says "Obtain Building Permit from Commonwealth Code Inspection Service (CCIS)"; the agency's office is at 1102 Sheller Ave, Chambersburg (717-262-0081). The Township office is at 4924 Orrstown Rd., Orrstown (717-532-8716), open Tuesday 8:00 am to 4:00 pm and Wednesday and Thursday 8:00 am to 2:00 pm. The Township's Ordinances page lists ordinances on junk, septic pumping, subdivision and land development and animal nuisances, and posts no building code or Uniform Construction Code adoption ordinance; the Permits page says "There is no zoning in Letterkenny Township." The Township's pages and Resolution 2021-1 set no roof layer rule.
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, Letterkenny Township's Permits page, read October 12, 2026, says "Residents must first obtain a Land Use Permit by visiting the township building during office hours. After receiving the Land Use Permit, you will take it to Commonwealth Code Inspection Service (CCIS) in Chambersburg to apply for the Building Permit," and the Township's Permit Check List says "Obtain Building Permit from Commonwealth Code Inspection Service (CCIS)"; the agency's office is at 1102 Sheller Ave, Chambersburg (717-262-0081). The Township office is at 4924 Orrstown Rd., Orrstown (717-532-8716), open Tuesday 8:00 am to 4:00 pm and Wednesday and Thursday 8:00 am to 2:00 pm. The Township's Ordinances page lists ordinances on junk, septic pumping, subdivision and land development and animal nuisances, and posts no building code or Uniform Construction Code adoption ordinance; the Permits page says "There is no zoning in Letterkenny Township." Resolution 2021-1 lists "Roof new or with structural change" as work needing a building permit from the agency and sets no sheathing rule of its own.
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. Letterkenny Township is in Franklin County. The Township's pages say nothing on sales tax.

Roofing questions: Township of Letterkenny, PA

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

Yes, a permit is required to replace a roof in Township of Letterkenny, PA. Letterkenny Township has its own Land Use Permit. The permit a reroof needs here is Letterkenny Township's Land Use Permit, a local permit, not a Uniform Construction Code building permit: the Township's Resolution 2021-1, enacted January 4, 2021 and linked from its Permits page, amends "the following fees for issuing Land Use Permits" and lists "Roofing Material Replacement (No Structural Changes)" under "$35.00 Land Use Permits that Do Not Need Building Permits" (read Oct 12, 2026). For the Uniform Construction Code building permit, the same resolution says "Land Use Permits that Do Not Need Building Permits" for that item and lists "Roof new or with structural change" under "$70.00 - Land Use Permits that Require Building Permits (from CCIS)." The Permits page also says "A permit is not required for minor repairs to existing buildings provided that no structural changes or modifications are involved"; it names no roof work, and this record does not decide whether a reroof is a minor repair. The Township's Land Use Permit application says it is "to build, erect, or remodel a structure in Letterkenny Township" and "Application for a Building Permit will not be accepted until a Land Use Permit is issued by the Township." 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 Land Use Permit requirement is one adopted under section 503, kept in effect by section 303(b)(1), or made under the municipality's other powers. Because the Township's enacted fee resolution lists roofing material replacement as a Land Use Permit, a reroof without one risks whatever the Township imposes; the resolution states no penalty. 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, Letterkenny Township's Permits page, read October 12, 2026, says "Residents must first obtain a Land Use Permit by visiting the township building during office hours. After receiving the Land Use Permit, you will take it to Commonwealth Code Inspection Service (CCIS) in Chambersburg to apply for the Building Permit," and the Township's Permit Check List says "Obtain Building Permit from Commonwealth Code Inspection Service (CCIS)"; the agency's office is at 1102 Sheller Ave, Chambersburg (717-262-0081). The Township office is at 4924 Orrstown Rd., Orrstown (717-532-8716), open Tuesday 8:00 am to 4:00 pm and Wednesday and Thursday 8:00 am to 2:00 pm. The Township's Resolution 2021-1 sets a Land Use Permit fee of $35.00 for roofing material replacement and sets no area or cost threshold below which none is needed.

Can you roof over an existing roof in Township of Letterkenny, 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, Letterkenny Township's Permits page, read October 12, 2026, says "Residents must first obtain a Land Use Permit by visiting the township building during office hours. After receiving the Land Use Permit, you will take it to Commonwealth Code Inspection Service (CCIS) in Chambersburg to apply for the Building Permit," and the Township's Permit Check List says "Obtain Building Permit from Commonwealth Code Inspection Service (CCIS)"; the agency's office is at 1102 Sheller Ave, Chambersburg (717-262-0081).

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

Yes.

What building code does Township of Letterkenny, 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.
