Adopted code

Town of Bloomsburg - Code Enforcement & Zoning Office

The Town of Bloomsburg's Code Enforcement & Zoning Office, at 301 E. Second Street, issues building permits; no Town text read names reroofing as permit work or as exempt, though the Town requires a permit for replacing roof sheathing. 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
No Town of Bloomsburg text read names reroofing as permit work or as exempt; the Town requires a building permit for replacing roof sheathing. The Code Enforcement page's "What kind of permits do I need?" list for one- and two-family dwellings covers decks, porches, accessory structures, fences, retaining walls, pools, signs, additions (including "adding a roof to a porch or deck"), alterations, new homes and demolition, and under Alterations requires a building permit for "Removal, cutting, reinforcement, drilling, or replacement of a load-bearing beam, header, roof sheathing, or wall." It does not name reroofing or roof covering replacement, and it adds "Please see the BCO with any questions about exemptions or exclusionary work." The Town's 2026 fee resolution (Resolution No. 06.22.2026.01) prices "Alterations, Renovations and Repairs to Existing Residential Buildings" by the cost of construction and has no residential roofing line; it lists "Roof Replacements" only among commercial projects. The Town's permit application offers "New Construction," "Repairs/Renovations" and "Alterations" and has no roofing box. Part 3 of Chapter 5 of the Town Code (Ord. 874, 2004) adopts the Uniform Construction Code, "as amended from time to time," by reference as the municipal building code, names no roof work either way and adds no permit clause of its own; Section 5-305 keeps in force building code ordinances adopted on or before July 1, 1999 "which equal or exceed the requirements of the Code," and Chapter 4, Buildings, is reserved. Section 5-103 requires a permit application "in accordance with the provisions of those other applicable codes and ordinances" the Office of Code Enforcement administers and sets no permit rule of its own. In the Historic District, Section 27-1310 of the zoning chapter says "all repairs, alterations, restorations, enlargements, demolitions, new construction or razing of structures in the Historic District shall require a building permit"; that clause reaches only the Historic District. 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." So no Town text read answers whether the ordinary reroof of a house outside the Historic District needs a permit; for that, the Town says "If you are unsure, contact the Building Code Official for clarification." Applications for building, zoning and demolition permits can be made through the Town's online portal. The fee resolution says "Work performed without approved permits will be assessed at double of the normal permit fee rate," and the Code Enforcement page says performing work regulated by the Uniform Construction Code without a permit "commits a summary offense." The Code Enforcement & Zoning Office telephone is 570-784-7123. Read for this answer: Parts 1 and 3 of Chapter 5 of the Town Code, Code Enforcement, in full; Chapter 4, Buildings (reserved); Part 2 of Chapter 8, Floodplains, and Sections 27-1006 and 27-1310 of the zoning chapter, whose permit clauses sit in those chapters; every page of a search of the whole Town Code for "roof" and for "reroofing," which found no permit provision naming roof work on houses; the Code Enforcement and Forms pages; the 2026 fee resolution; the Town's paper permit application and its online Building/Zoning Application.
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 Town of Bloomsburg administers the code itself: Section 5-301 of the Town Code says "The Town of Bloomsburg hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 5-102 gives the Town's Code Enforcement Officer "the issuance of permits," and the Town's Code Enforcement page tells readers to "contact the Building Code Official for clarification." The Code Enforcement & Zoning Office is at 301 E. Second Street, Bloomsburg. Section 5-302 adopts the Uniform Construction Code, "as amended from time to time," as the municipal building code and changes nothing in the code's roofing provisions. The Town's 2026 fee resolution says "Residential UCC permits are for one and two-family dwellings, as defined by the 2018 IRC definition of a residential building, and any subsequent revisions," and Part 3 of Chapter 5 names no edition; this record has not read the 2018 edition's text and does not decide which edition the Town applies.
Repair permit threshold
No Town of Bloomsburg text read names reroofing as permit work or as exempt; the Town requires a building permit for replacing roof sheathing. The Code Enforcement page's "What kind of permits do I need?" list for one- and two-family dwellings covers decks, porches, accessory structures, fences, retaining walls, pools, signs, additions (including "adding a roof to a porch or deck"), alterations, new homes and demolition, and under Alterations requires a building permit for "Removal, cutting, reinforcement, drilling, or replacement of a load-bearing beam, header, roof sheathing, or wall." It does not name reroofing or roof covering replacement, and it adds "Please see the BCO with any questions about exemptions or exclusionary work." The Town's 2026 fee resolution (Resolution No. 06.22.2026.01) prices "Alterations, Renovations and Repairs to Existing Residential Buildings" by the cost of construction and has no residential roofing line; it lists "Roof Replacements" only among commercial projects. The Town's permit application offers "New Construction," "Repairs/Renovations" and "Alterations" and has no roofing box. Part 3 of Chapter 5 of the Town Code (Ord. 874, 2004) adopts the Uniform Construction Code, "as amended from time to time," by reference as the municipal building code, names no roof work either way and adds no permit clause of its own; Section 5-305 keeps in force building code ordinances adopted on or before July 1, 1999 "which equal or exceed the requirements of the Code," and Chapter 4, Buildings, is reserved. Section 5-103 requires a permit application "in accordance with the provisions of those other applicable codes and ordinances" the Office of Code Enforcement administers and sets no permit rule of its own. In the Historic District, Section 27-1310 of the zoning chapter says "all repairs, alterations, restorations, enlargements, demolitions, new construction or razing of structures in the Historic District shall require a building permit"; that clause reaches only the Historic District. 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." So no Town text read answers whether the ordinary reroof of a house outside the Historic District needs a permit; for that, the Town says "If you are unsure, contact the Building Code Official for clarification." 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 Town of Bloomsburg administers the code itself: Section 5-301 of the Town Code says "The Town of Bloomsburg hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 5-102 gives the Town's Code Enforcement Officer "the issuance of permits," and the Town's Code Enforcement page tells readers to "contact the Building Code Official for clarification." The Code Enforcement & Zoning Office is at 301 E. Second Street, Bloomsburg. The Town's line for roofs, quoted at the start, is the replacement of roof sheathing, which needs a building permit; no Town text sets an area, percentage or cost threshold for roof 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 Town of Bloomsburg administers the code itself: Section 5-301 of the Town Code says "The Town of Bloomsburg hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 5-102 gives the Town's Code Enforcement Officer "the issuance of permits," and the Town's Code Enforcement page tells readers to "contact the Building Code Official for clarification." The Code Enforcement & Zoning Office is at 301 E. Second Street, Bloomsburg. Part 3 of Chapter 5 of the Town Code changes nothing in the code's reroofing provisions, and the Town's pages say nothing on roof layers. The Town's 2026 fee resolution says "Residential UCC permits are for one and two-family dwellings, as defined by the 2018 IRC definition of a residential building, and any subsequent revisions," and Part 3 of Chapter 5 names no edition; the text above is the 2021 edition's, the 2018 edition's reroofing text was not read for this record, and this record does not decide which edition the Town applies.
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 Town of Bloomsburg administers the code itself: Section 5-301 of the Town Code says "The Town of Bloomsburg hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 5-102 gives the Town's Code Enforcement Officer "the issuance of permits," and the Town's Code Enforcement page tells readers to "contact the Building Code Official for clarification." The Code Enforcement & Zoning Office is at 301 E. Second Street, Bloomsburg. The Town's Code Enforcement page requires a building permit for "Removal, cutting, reinforcement, drilling, or replacement of a load-bearing beam, header, roof sheathing, or wall," so replacing roof sheathing on a house in Bloomsburg is building permit work. Part 3 of Chapter 5 of the Town Code changes nothing in the code's roof sheathing provisions. The Town's 2026 fee resolution says "Residential UCC permits are for one and two-family dwellings, as defined by the 2018 IRC definition of a residential building, and any subsequent revisions," and Part 3 of Chapter 5 names no edition; the text above is the 2021 edition's, the 2018 edition's sheathing text was not read for this record, and this record does not decide which edition the Town applies.
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 Town of Bloomsburg is in Columbia County. The Town's permit pages and 2026 fee resolution say nothing on sales tax.

Roofing questions: Bloomsburg, PA

When does a roof repair need a permit in Bloomsburg, PA?

No Town of Bloomsburg text read names reroofing as permit work or as exempt; the Town requires a building permit for replacing roof sheathing. The Code Enforcement page's "What kind of permits do I need?" list for one- and two-family dwellings covers decks, porches, accessory structures, fences, retaining walls, pools, signs, additions (including "adding a roof to a porch or deck"), alterations, new homes and demolition, and under Alterations requires a building permit for "Removal, cutting, reinforcement, drilling, or replacement of a load-bearing beam, header, roof sheathing, or wall." It does not name reroofing or roof covering replacement, and it adds "Please see the BCO with any questions about exemptions or exclusionary work." The Town's 2026 fee resolution (Resolution No. 06.22.2026.01) prices "Alterations, Renovations and Repairs to Existing Residential Buildings" by the cost of construction and has no residential roofing line; it lists "Roof Replacements" only among commercial projects. The Town's permit application offers "New Construction," "Repairs/Renovations" and "Alterations" and has no roofing box. Part 3 of Chapter 5 of the Town Code (Ord. 874, 2004) adopts the Uniform Construction Code, "as amended from time to time," by reference as the municipal building code, names no roof work either way and adds no permit clause of its own; Section 5-305 keeps in force building code ordinances adopted on or before July 1, 1999 "which equal or exceed the requirements of the Code," and Chapter 4, Buildings, is reserved. Section 5-103 requires a permit application "in accordance with the provisions of those other applicable codes and ordinances" the Office of Code Enforcement administers and sets no permit rule of its own. In the Historic District, Section 27-1310 of the zoning chapter says "all repairs, alterations, restorations, enlargements, demolitions, new construction or razing of structures in the Historic District shall require a building permit"; that clause reaches only the Historic District. 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." So no Town text read answers whether the ordinary reroof of a house outside the Historic District needs a permit; for that, the Town says "If you are unsure, contact the Building Code Official for clarification." 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 Town of Bloomsburg administers the code itself: Section 5-301 of the Town Code says "The Town of Bloomsburg hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 5-102 gives the Town's Code Enforcement Officer "the issuance of permits," and the Town's Code Enforcement page tells readers to "contact the Building Code Official for clarification." The Code Enforcement & Zoning Office is at 301 E. Second Street, Bloomsburg. The Town's line for roofs, quoted at the start, is the replacement of roof sheathing, which needs a building permit; no Town text sets an area, percentage or cost threshold for roof work.

Can you roof over an existing roof in Bloomsburg, 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 Town of Bloomsburg administers the code itself: Section 5-301 of the Town Code says "The Town of Bloomsburg hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 5-102 gives the Town's Code Enforcement Officer "the issuance of permits," and the Town's Code Enforcement page tells readers to "contact the Building Code Official for clarification." The Code Enforcement & Zoning Office is at 301 E. Second Street, Bloomsburg. Part 3 of Chapter 5 of the Town Code changes nothing in the code's reroofing provisions, and the Town's pages say nothing on roof layers. The Town's 2026 fee resolution says "Residential UCC permits are for one and two-family dwellings, as defined by the 2018 IRC definition of a residential building, and any subsequent revisions," and Part 3 of Chapter 5 names no edition; the text above is the 2021 edition's, the 2018 edition's reroofing text was not read for this record, and this record does not decide which edition the Town applies.

Do roofing contractors need a license or registration in Bloomsburg, PA?

Yes.

What building code does Bloomsburg, 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 Town of Bloomsburg administers the code itself: Section 5-301 of the Town Code says "The Town of Bloomsburg hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 5-102 gives the Town's Code Enforcement Officer "the issuance of permits," and the Town's Code Enforcement page tells readers to "contact the Building Code Official for clarification."
