Do you need a permit to replace a roof in Borough of Carlisle, PA?

Roofing questions: Borough of Carlisle, PA

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

Carlisle Borough's code adopts the Uniform Construction Code and names no roof work as permit work or as exempt, except that historic district exterior work needs a certificate of appropriateness. Chapter 89 of the Borough Code, Building Construction (Sections 89-1 to 89-9), adopts the Pennsylvania Construction Code Act and its regulations and names no roof work as permit work or as exempt. The Borough's "When Do I Need a Permit?" guide (read October 7, 2026) lists work needing a building and zoning permit or a zoning permit only, does not name roofing, and says "This list is meant to provide you with a quick reference guide. To be absolutely certain if you need a permit of any kind, or if you have any questions, please contact the Borough's Codes Office at 717-240-6930." The Borough's permit fee schedule (Resolution No. 05-14-26-01) names "roof replacements" only in its COMMERCIAL "Miscellaneous Construction Project" category; its RESIDENTIAL categories are new dwellings and additions and solar systems. In the Historic Preservation District, Section 255-154 of the Zoning chapter says "A certificate of appropriateness is required for any erection, construction, reconstruction, exterior alteration, repair, restoration, sandblasting, demolition or razing of a building" where the work will affect the exterior seen from a public way, and "The Borough Zoning Officer shall not issue a permit or written authorization for any such work until the Borough Council has issued a certificate of appropriateness"; the Borough's HARB application lists "Roof" among types of work and places roofing replacement on its consent agenda where it "must be replaced with in-kind materials." The Borough has published no statement on whether a house reroof outside the historic district needs a permit, and this record does not state whether one is required. 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 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, Carlisle Borough administers the code itself: Section 89-1 of the Borough Code says "The Borough hereby elects to administer and enforce the provisions of the code, as amended from time to time," Section 89-4 A provides for "the designation of an employee of the Borough to serve as the Building Code Official," and the Borough's Code Enforcement page says its Codes Office, part of the Sustainable Community and Economic Planning Department, "also handles construction inspection." No Borough ordinance reaching residential reroofing outside the historic district was found in Chapter 89 or Chapter 120 of the Borough Code, and the Borough's pages and fee schedule set no threshold for house roof work.

Can you roof over an existing roof in Borough of Carlisle, 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, Carlisle Borough administers the code itself: Section 89-1 of the Borough Code says "The Borough hereby elects to administer and enforce the provisions of the code, as amended from time to time," Section 89-4 A provides for "the designation of an employee of the Borough to serve as the Building Code Official," and the Borough's Code Enforcement page says its Codes Office, part of the Sustainable Community and Economic Planning Department, "also handles construction inspection." Chapter 89 of the Borough Code changes nothing in the code's reroofing provisions, and the Borough's pages say nothing on roof layers. No Borough ordinance reaching residential reroofing outside the historic district was found, so whether a Borough ordinance brings a house reroof within the Uniform Construction Code is not stated here.

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

Yes.

What building code does Borough of Carlisle, 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, Carlisle Borough administers the code itself: Section 89-1 of the Borough Code says "The Borough hereby elects to administer and enforce the provisions of the code, as amended from time to time," Section 89-4 A provides for "the designation of an employee of the Borough to serve as the Building Code Official," and the Borough's Code Enforcement page says its Codes Office, part of the Sustainable Community and Economic Planning Department, "also handles construction inspection." Section 89-7 names Chapter 89 the "Carlisle Borough Building Code," and Section 89-9 amends Table R301.2(1) of the International Residential Code with the Borough's climatic and geographic design criteria, whose attached table marks ice shield underlayment required "Yes"; Chapter 89 changes nothing in the code's roofing provisions and names no code edition, and the Borough's pages name none.
