Adopted code

Hampden Township - Department of Community Development

No, Township of Hampden, PA does not require a permit for like-for-like roof replacement (Hampden Township - Department of Community Development). The exception names re-shingling that is non-structural; the department's page says nothing about other roof coverings or about sheathing or framing work. Hampden Township's Department of Community Development says a residential building permit is needed "For any construction work that exceeds $500.00 in total project cost" and lists among the "Exceptions:" "Non-structural roof re-shingling" (Community Development page, read October 6, 2026). The other listed exceptions are window replacement, "Replacement siding, fascia, gutters, downspouts" and kitchen and bathroom remodeling that is repair or replacement of existing items. The Township's own code names no roof work either way: Chapter 5, Part 1 (Sections 101 to 105) adopts the Uniform Construction Code "as amended and supplemented from time to time" and has no permit clause of its own for house repairs or alterations, and the department's residential Construction Permit Application lists "Repair" and "Alteration" among its types of improvement with no roofing category. The no-permit line is the department's stated practice, and this record does not decide whether it is the department's reading of the state exclusions. 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." In practice, structural roof work, and work the department's exceptions do not name, goes through a residential building permit: applications are filed at the Department of Community Development, 209 S. Sporting Hill Road, Mechanicsburg (717-761-0119), open 8:00 a.m. to 4:30 p.m. every weekday, with "Two (2) sets of construction documents"; the department says processing takes "within 15 business days for most standard residential" permits. The department's Other Permits page lists a Contractor License Application, which asks for the contractor's "PA Contractor Registration" and a workers' compensation certificate or exemption; the pages read do not say which work needs it. Section 105 fills in the code's climatic table, Table R301.2(1), with "Ice Barrier Underlayment: Yes" among its entries. The Township's pages name no code edition, while Section 105's local amendments are written against the 2009 International Codes and say they apply "to all future codes adopted triennially by the Department"; this record has not read the 2009 edition's text. Read for this answer: Chapter 5, Part 1 of the Township Code, Uniform Construction Code, with its local amendments in Section 105, in full; a search of the whole Township Code for "roof," which found no permit provision naming roof work; the department's Community Development and Other Permits pages; and its 2026 residential Construction Permit Application, whose list of improvement types stands in for a fee schedule, which the Township's site does not post.

Permit process note
The exception names re-shingling that is non-structural; the department's page says nothing about other roof coverings or about sheathing or framing work. Hampden Township's Department of Community Development says a residential building permit is needed "For any construction work that exceeds $500.00 in total project cost" and lists among the "Exceptions:" "Non-structural roof re-shingling" (Community Development page, read October 6, 2026). The other listed exceptions are window replacement, "Replacement siding, fascia, gutters, downspouts" and kitchen and bathroom remodeling that is repair or replacement of existing items. The Township's own code names no roof work either way: Chapter 5, Part 1 (Sections 101 to 105) adopts the Uniform Construction Code "as amended and supplemented from time to time" and has no permit clause of its own for house repairs or alterations, and the department's residential Construction Permit Application lists "Repair" and "Alteration" among its types of improvement with no roofing category. The no-permit line is the department's stated practice, and this record does not decide whether it is the department's reading of the state exclusions. 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." In practice, structural roof work, and work the department's exceptions do not name, goes through a residential building permit: applications are filed at the Department of Community Development, 209 S. Sporting Hill Road, Mechanicsburg (717-761-0119), open 8:00 a.m. to 4:30 p.m. every weekday, with "Two (2) sets of construction documents"; the department says processing takes "within 15 business days for most standard residential" permits.

Read for this answer: Chapter 5, Part 1 of the Township Code, Uniform Construction Code, with its local amendments in Section 105, in full; a search of the whole Township Code for "roof," which found no permit provision naming roof work; the department's Community Development and Other Permits pages; and its 2026 residential Construction Permit Application, whose list of improvement types stands in for a fee schedule, which the Township's site does not post.
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, Hampden Township administers the code itself: Section 102 of the Township Code says "Hampden Township hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 103 assigns administration to the Township's Director of Community Development and its other code staff, and the Department of Community Development reviews building permit applications. Section 105 of the Township Code amends the model codes the State adopts, chiefly to name the Township and fill in its climatic data, and amends no section of Chapter 9 of the International Residential Code. The Township's pages name no code edition, while Section 105's local amendments are written against the 2009 International Codes and say they apply "to all future codes adopted triennially by the Department"; this record has not read the 2009 edition's text. No ordinance reaching residential reroofing was found in Chapter 5, Part 1, read in full, or in a search of the whole Township Code for "roof"; the department's page lists "Non-structural roof re-shingling" among the exceptions to its residential building permit.
Repair permit threshold
Hampden Township's Department of Community Development says a residential building permit is needed "For any construction work that exceeds $500.00 in total project cost" and lists among the "Exceptions:" "Non-structural roof re-shingling" (Community Development page, read October 6, 2026). The other listed exceptions are window replacement, "Replacement siding, fascia, gutters, downspouts" and kitchen and bathroom remodeling that is repair or replacement of existing items. The exception names re-shingling that is non-structural; the department's page says nothing about other roof coverings or about sheathing or framing work. 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. The Township's own code names no roof work either way: Chapter 5, Part 1 (Sections 101 to 105) adopts the Uniform Construction Code "as amended and supplemented from time to time" and has no permit clause of its own for house repairs or alterations, and the department's residential Construction Permit Application lists "Repair" and "Alteration" among its types of improvement with no roofing category. The no-permit line is the department's stated practice. Under state law, Act 45 section 104(b)(5) and (6) list "Alterations to residential buildings which do not make structural changes or changes to means of egress" and "Repairs to residential buildings" among work the Act does not apply to, "except as might be required by ordinances in effect pursuant to section 303(b)(1) or adopted pursuant to section 503," and 34 Pa. Code 403.62(c) says "A permit is not required for the exceptions listed in § 403.1(b) (relating to scope) and the following, if the work does not violate a law or ordinance." State law sets no square-footage or percentage threshold for roof work; any threshold is set locally. The Uniform Construction Code "does not apply to" "Alterations to residential buildings which do not make structural changes or changes to means of egress, except as required by ordinances in effect under sections 303(b)(1) or 503 of the act" or to "Repairs to residential buildings, except as required by ordinances in effect under sections 303(b)(1) and 503 of the act" (34 Pa. Code 403.1(b)(8) and (9)), and "A permit is not required for the exceptions listed in § 403.1(b) (relating to scope) and the following, if the work does not violate a law or ordinance" (34 Pa. Code 403.62(c)). For houses the regulation adds: "An ordinary repair does not require a permit." Its list of work that is not an ordinary repair names cutting away a load-bearing wall, "The removal or cutting of any structural beam or load-bearing support," changes to a required means of egress, and new or relocated piping, wiring or mechanical work (34 Pa. Code 403.62(d)); roofing is not named. A municipality may require more: under Act 45 section 503(c) it "may enact ordinances pursuant to this section which adopt additional code requirements for alterations or repairs to residential buildings," after a public hearing and after filing the proposed ordinance with the Department of Labor and Industry. These rules concern a "Residential building," which the regulation defines as "Detached one-family and two-family dwellings and townhouses which are not more than three stories above grade plane in height with a separate means of egress and their accessory structures" (34 Pa. Code 401.1). Everything above is Pennsylvania state law, the same in every municipality. Locally, Hampden Township administers the code itself: Section 102 of the Township Code says "Hampden Township hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 103 assigns administration to the Township's Director of Community Development and its other code staff, and the Department of Community Development reviews building permit applications. Chapter 5, Part 1, read in full, sets no threshold for roof work; the $500 line and the re-shingling exception above are the department's own.
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, Hampden Township administers the code itself: Section 102 of the Township Code says "Hampden Township hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 103 assigns administration to the Township's Director of Community Development and its other code staff, and the Department of Community Development reviews building permit applications. Section 105 of the Township Code amends no section of Chapter 9, and the department's pages say nothing on roof layers; they list "Non-structural roof re-shingling" among the exceptions to the residential building permit. The Township's pages name no code edition, while Section 105's local amendments are written against the 2009 International Codes and say they apply "to all future codes adopted triennially by the Department"; this record has not read the 2009 edition's text.
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, Hampden Township administers the code itself: Section 102 of the Township Code says "Hampden Township hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 103 assigns administration to the Township's Director of Community Development and its other code staff, and the Department of Community Development reviews building permit applications. Section 105 of the Township Code amends neither Section R803 nor any Chapter 9 section. The department lists "Non-structural roof re-shingling" among the exceptions to its residential building permit and does not say whether replacing sheathing is structural. The Township's pages name no code edition, while Section 105's local amendments are written against the 2009 International Codes and say they apply "to all future codes adopted triennially by the Department"; this record has not read the 2009 edition's text.
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. Hampden Township is in Cumberland County. Its Department of Community Development, which administers the Uniform Construction Code there, states nothing on sales tax on the permit pages and application read for this record.

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

No, Township of Hampden, PA does not require a permit to replace a roof. Hampden Township's Department of Community Development says a residential building permit is needed "For any construction work that exceeds $500.00 in total project cost" and lists among the "Exceptions:" "Non-structural roof re-shingling" (Community Development page, read October 6, 2026). The other listed exceptions are window replacement, "Replacement siding, fascia, gutters, downspouts" and kitchen and bathroom remodeling that is repair or replacement of existing items. The exception names re-shingling that is non-structural; the department's page says nothing about other roof coverings or about sheathing or framing work.

The no-permit line is the department's stated practice. 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.

Can you roof over an existing roof in Township of Hampden, 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, Hampden Township administers the code itself: Section 102 of the Township Code says "Hampden Township hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 103 assigns administration to the Township's Director of Community Development and its other code staff, and the Department of Community Development reviews building permit applications. Section 105 of the Township Code amends no section of Chapter 9, and the department's pages say nothing on roof layers; they list "Non-structural roof re-shingling" among the exceptions to the residential building permit. The Township's pages name no code edition, while Section 105's local amendments are written against the 2009 International Codes and say they apply "to all future codes adopted triennially by the Department"; this record has not read the 2009 edition's text.

What building code does Township of Hampden, 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).

Section 105 of the Township Code amends the model codes the State adopts, chiefly to name the Township and fill in its climatic data, and amends no section of Chapter 9 of the International Residential Code. The Township's pages name no code edition, while Section 105's local amendments are written against the 2009 International Codes and say they apply "to all future codes adopted triennially by the Department"; this record has not read the 2009 edition's text. No ordinance reaching residential reroofing was found in Chapter 5, Part 1, read in full, or in a search of the whole Township Code for "roof"; the department's page lists "Non-structural roof re-shingling" among the exceptions to its residential building permit.
