Roofing questions: Borough of Columbia, PA

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

Columbia Borough's permit page lists roof replacement among work needing a zoning permit and requires a building permit where more than half the roof plywood is removed. The Borough's Permit Applications page (read October 9, 2026) says "AN APPROVED PERMIT IS REQUIRED BEFORE ANY WORK BEGINS" and lists, under "Zoning Permit would be required for the following," the entry "Roof Replacement / Repair (building permit required if more than 1/2 plywood removed)." That is a zoning permit, a separate Borough permit from a building permit under the Uniform Construction Code; expect to need it for a reroof, and a building permit as well where more than half the roof plywood comes off. The Borough's 2026 fee schedule prices a zoning permit at $50 under Section 220-7 and lists a "Penalty for doing work without a valid permit" of $500. Section 220-3B of the Borough's zoning chapter says "Ordinary repairs and maintenance to existing structures shall not by itself be regulated by this chapter." Article V of Chapter 112 of the Borough Code, Uniform Construction Code (Ord. No. 734, June 14, 2004), names no roof work either way and adds no permit clause for residential repairs or alterations, and no Borough building code ordinance from before the Uniform Construction Code was found in the published Borough Code. The fee schedule's building permit lines are priced by project cost ("First $1,000.00" $50, "Each Additional $1,000.00" $10) and name no roof work, and the application's Description of Work boxes include "Roof Construction." 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, Columbia Borough issues building and zoning permits on one Borough application. Section 112-14 of the Borough Code ratifies the Borough's election "to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 112-15B says "the Code Official and/or Code Enforcement Officer of the Borough of Columbia is authorized to enforce the Code," the Borough's Code Compliance page lists a Zoning/Code Compliance Manager and an Inspector, each with a BCO credential, and the Borough's 2026 permit application says "A third-party review, including inspections, may be required for some projects with an additional fee." The only line for roof work in the Borough's pages read for this record is the Permit Applications page's "building permit required if more than 1/2 plywood removed"; no Borough text read sets an area or cost threshold for roof work.

Can you roof over an existing roof in Borough of Columbia, 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, Columbia Borough issues building and zoning permits on one Borough application. Section 112-14 of the Borough Code ratifies the Borough's election "to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 112-15B says "the Code Official and/or Code Enforcement Officer of the Borough of Columbia is authorized to enforce the Code," the Borough's Code Compliance page lists a Zoning/Code Compliance Manager and an Inspector, each with a BCO credential, and the Borough's 2026 permit application says "A third-party review, including inspections, may be required for some projects with an additional fee." Article V of Chapter 112 of the Borough Code changes nothing in the code's reroofing provisions, and the Borough's pages say nothing on roof layers.

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

Yes.

What building code does Borough of Columbia, 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, Columbia Borough issues building and zoning permits on one Borough application. Section 112-14 of the Borough Code ratifies the Borough's election "to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 112-15B says "the Code Official and/or Code Enforcement Officer of the Borough of Columbia is authorized to enforce the Code," the Borough's Code Compliance page lists a Zoning/Code Compliance Manager and an Inspector, each with a BCO credential, and the Borough's 2026 permit application says "A third-party review, including inspections, may be required for some projects with an additional fee." Section 112-14 confirms that election "as the Uniform Construction Code contained in 34 Pa. Code, Chapters 401 through 405, as amended from time to time," names no edition, and changes nothing in the code's roofing provisions; the Borough's permit pages name no code edition.
