Adopted code

Dallastown Borough - Borough Office (Building Permits)

Yes, a permit is required to replace a roof in Borough of Dallastown, PA, issued by Dallastown Borough - Borough Office (Building Permits). Dallastown Borough's Building Permits page lists roofing as an item requiring a building permit. The Borough's Building Permits & Guidelines page says "Items requiring a building permit include, but are not limited to the following:" and lists "Roofing" under that heading, beside window replacements where the openings are altered, decks, and additions. Section 90-3 of the Borough Code, the Building Permit Code of 1961, says "It shall be unlawful for any person, firm, association or corporation to erect, construct, enlarge, alter, repair, move, remove or demolish any building or structure within the limits of the Borough of Dallastown, York County, Pennsylvania, unless a permit therefor shall first be secured as hereinafter provided." Section 90-19.1 (Ord. No. 533 of 2005) makes residential repairs and non-structural alterations subject to the Uniform Construction Code but exempts from "such compliance" a list of work that includes "(9) Replacement of any roof material so long as the existing roof material is removed prior to installation of new," and Section 90-5E says "Where painting or refurbishing is done only as repair, no permit or fee shall be required." The Borough's own Building Permits page still lists "Roofing" as an item requiring a building permit, with no tear-off or other condition. 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 municipality's requirement is one adopted under section 503 or kept in effect by section 303(b)(1). The Department of Labor and Industry's register of municipal code change ordinances lists a Dallastown Borough filing that "Requires a building permit for all residential alterations and repairs, except where specifically exempted in this ordinance," found in compliance with an approval letter mailed 7/20/05, "Enacted 9 / 12 / 05." In practice, expect the Borough to require a building permit for a reroof. Section 90-10 says a violation of the Building Permit Code is punishable "by a fine of not more than $1,000, plus costs of prosecution," and that each day work continues "without first securing a building permit" is a separate offense. The page says construction documents go to the Borough Office "in 3 or more sets for each application," that each application must have a plan review, that a residential plan review "will take up to 15 business days," and that plan review, inspections and permit are paid for before the permit is issued. The Borough Office is at 175 East Broad Street, Dallastown, phone 717-244-6626. Read for this record: Chapter 90 of the Borough Code, Building Construction (Article I, Building Permits, and Article II, Uniform Construction Code, Sections 90-1 to 90-24), in full; every page of a search of the whole Borough Code for "roof" and for "reroofing"; the Borough's Building Permits & Guidelines, Applications & Forms and Contact Us pages; and its 2026 residential building permit application, whose fee line reads "$49.50 (UP TO- $1K) ADD $2 PER THOUSAND OVER $1K + 3RD PARTY FEES" (Section 90-5 leaves rates to a fee schedule the Borough Council adopts; that schedule was not read for this record).

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, Dallastown Borough in York County takes building permit applications at its Borough Office, 175 East Broad Street, and its residential building permit application marks the date issued for "BOROUGH USE ONLY." Section 90-18 of the Borough Code says the Borough "hereby elects to administer and enforce" the Pennsylvania Construction Code Act, and an editor's note to Section 90-20 says Ordinance No. 518, adopted 6-28-2004, "authorizes and approves an agreement with the Township of York for the administration of the Uniform Construction Code"; the application carries a line for "3RD PARTY FEES." Section 90-19 adopts "The Uniform Construction Code, contained in 34 Pa. Code, Chapters 401 through 405, as amended from time to time," as the municipal building code, and Chapter 90 changes nothing in the code's roofing provisions. Section 90-19 adopts the Uniform Construction Code "as amended from time to time" and names no edition, and the Borough's Building Permits & Guidelines page says construction documents must show how the work conforms to "the IRC (International Residential Code) and IBC (International Building Code) of 2018"; this record has not read the 2018 edition's text and does not decide which edition the Borough applies.
Repair permit threshold
Dallastown Borough's Building Permits page lists roofing as an item requiring a building permit. The Borough's Building Permits & Guidelines page says "Items requiring a building permit include, but are not limited to the following:" and lists "Roofing" under that heading, beside window replacements where the openings are altered, decks, and additions. Section 90-3 of the Borough Code, the Building Permit Code of 1961, says "It shall be unlawful for any person, firm, association or corporation to erect, construct, enlarge, alter, repair, move, remove or demolish any building or structure within the limits of the Borough of Dallastown, York County, Pennsylvania, unless a permit therefor shall first be secured as hereinafter provided." Section 90-19.1 (Ord. No. 533 of 2005) makes residential repairs and non-structural alterations subject to the Uniform Construction Code but exempts from "such compliance" a list of work that includes "(9) Replacement of any roof material so long as the existing roof material is removed prior to installation of new," and Section 90-5E says "Where painting or refurbishing is done only as repair, no permit or fee shall be required." The Borough's own Building Permits page still lists "Roofing" as an item requiring a building permit, with no tear-off or other condition. 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 municipality's requirement is one adopted under section 503 or kept in effect by section 303(b)(1). The Department of Labor and Industry's register of municipal code change ordinances lists a Dallastown Borough filing that "Requires a building permit for all residential alterations and repairs, except where specifically exempted in this ordinance," found in compliance with an approval letter mailed 7/20/05, "Enacted 9 / 12 / 05." In practice, expect the Borough to require a building permit for a reroof. Section 90-10 says a violation of the Building Permit Code is punishable "by a fine of not more than $1,000, plus costs of prosecution," and that each day work continues "without first securing a building permit" is a separate offense. 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, Dallastown Borough in York County takes building permit applications at its Borough Office, 175 East Broad Street, and its residential building permit application marks the date issued for "BOROUGH USE ONLY." Section 90-18 of the Borough Code says the Borough "hereby elects to administer and enforce" the Pennsylvania Construction Code Act, and an editor's note to Section 90-20 says Ordinance No. 518, adopted 6-28-2004, "authorizes and approves an agreement with the Township of York for the administration of the Uniform Construction Code"; the application carries a line for "3RD PARTY FEES." The Borough's Building Permits page states no size or percentage threshold for roofing; the only roof line in the Borough Code is the Section 90-19.1(9) exemption from Uniform Construction Code compliance quoted at the start, for roof material replacement where the existing material is removed first.
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, Dallastown Borough in York County takes building permit applications at its Borough Office, 175 East Broad Street, and its residential building permit application marks the date issued for "BOROUGH USE ONLY." Section 90-18 of the Borough Code says the Borough "hereby elects to administer and enforce" the Pennsylvania Construction Code Act, and an editor's note to Section 90-20 says Ordinance No. 518, adopted 6-28-2004, "authorizes and approves an agreement with the Township of York for the administration of the Uniform Construction Code"; the application carries a line for "3RD PARTY FEES." Chapter 90 of the Borough Code changes nothing in the code's reroofing provisions; its Section 90-19.1(9) exempts from Uniform Construction Code compliance "Replacement of any roof material so long as the existing roof material is removed prior to installation of new," which speaks to tear-off jobs and sets no layer rule, and the Borough's pages say nothing on roof layers. Section 90-19 adopts the Uniform Construction Code "as amended from time to time" and names no edition, and the Borough's Building Permits & Guidelines page says construction documents must show how the work conforms to "the IRC (International Residential Code) and IBC (International Building Code) of 2018"; 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 Borough 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, Dallastown Borough in York County takes building permit applications at its Borough Office, 175 East Broad Street, and its residential building permit application marks the date issued for "BOROUGH USE ONLY." Section 90-18 of the Borough Code says the Borough "hereby elects to administer and enforce" the Pennsylvania Construction Code Act, and an editor's note to Section 90-20 says Ordinance No. 518, adopted 6-28-2004, "authorizes and approves an agreement with the Township of York for the administration of the Uniform Construction Code"; the application carries a line for "3RD PARTY FEES." Chapter 90 of the Borough Code changes nothing in the code's roof sheathing provisions, and the Borough's pages draw no separate line for roof sheathing. Section 90-19 adopts the Uniform Construction Code "as amended from time to time" and names no edition, and the Borough's Building Permits & Guidelines page says construction documents must show how the work conforms to "the IRC (International Residential Code) and IBC (International Building Code) of 2018"; 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 Borough 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. Dallastown Borough is in York County. The Borough's permit pages and residential building permit application say nothing on sales tax.

Roofing questions: Borough of Dallastown, PA

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

Yes, a permit is required to replace a roof in Borough of Dallastown, PA. Dallastown Borough's Building Permits page lists roofing as an item requiring a building permit. The Borough's Building Permits & Guidelines page says "Items requiring a building permit include, but are not limited to the following:" and lists "Roofing" under that heading, beside window replacements where the openings are altered, decks, and additions. Section 90-3 of the Borough Code, the Building Permit Code of 1961, says "It shall be unlawful for any person, firm, association or corporation to erect, construct, enlarge, alter, repair, move, remove or demolish any building or structure within the limits of the Borough of Dallastown, York County, Pennsylvania, unless a permit therefor shall first be secured as hereinafter provided." Section 90-19.1 (Ord. No. 533 of 2005) makes residential repairs and non-structural alterations subject to the Uniform Construction Code but exempts from "such compliance" a list of work that includes "(9) Replacement of any roof material so long as the existing roof material is removed prior to installation of new," and Section 90-5E says "Where painting or refurbishing is done only as repair, no permit or fee shall be required." The Borough's own Building Permits page still lists "Roofing" as an item requiring a building permit, with no tear-off or other condition. 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 municipality's requirement is one adopted under section 503 or kept in effect by section 303(b)(1). The Department of Labor and Industry's register of municipal code change ordinances lists a Dallastown Borough filing that "Requires a building permit for all residential alterations and repairs, except where specifically exempted in this ordinance," found in compliance with an approval letter mailed 7/20/05, "Enacted 9 / 12 / 05." In practice, expect the Borough to require a building permit for a reroof. Section 90-10 says a violation of the Building Permit Code is punishable "by a fine of not more than $1,000, plus costs of prosecution," and that each day work continues "without first securing a building permit" is a separate offense. 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.

Can you roof over an existing roof in Borough of Dallastown, 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, Dallastown Borough in York County takes building permit applications at its Borough Office, 175 East Broad Street, and its residential building permit application marks the date issued for "BOROUGH USE ONLY." Section 90-18 of the Borough Code says the Borough "hereby elects to administer and enforce" the Pennsylvania Construction Code Act, and an editor's note to Section 90-20 says Ordinance No. 518, adopted 6-28-2004, "authorizes and approves an agreement with the Township of York for the administration of the Uniform Construction Code"; the application carries a line for "3RD PARTY FEES." Chapter 90 of the Borough Code changes nothing in the code's reroofing provisions; its Section 90-19.1(9) exempts from Uniform Construction Code compliance "Replacement of any roof material so long as the existing roof material is removed prior to installation of new," which speaks to tear-off jobs and sets no layer rule, and the Borough's pages say nothing on roof layers. Section 90-19 adopts the Uniform Construction Code "as amended from time to time" and names no edition, and the Borough's Building Permits & Guidelines page says construction documents must show how the work conforms to "the IRC (International Residential Code) and IBC (International Building Code) of 2018"; 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 Borough applies.

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

Yes.

What building code does Borough of Dallastown, 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, Dallastown Borough in York County takes building permit applications at its Borough Office, 175 East Broad Street, and its residential building permit application marks the date issued for "BOROUGH USE ONLY." Section 90-18 of the Borough Code says the Borough "hereby elects to administer and enforce" the Pennsylvania Construction Code Act, and an editor's note to Section 90-20 says Ordinance No. 518, adopted 6-28-2004, "authorizes and approves an agreement with the Township of York for the administration of the Uniform Construction Code"; the application carries a line for "3RD PARTY FEES." Section 90-19 adopts "The Uniform Construction Code, contained in 34 Pa. Code, Chapters 401 through 405, as amended from time to time," as the municipal building code, and Chapter 90 changes nothing in the code's roofing provisions. Section 90-19 adopts the Uniform Construction Code "as amended from time to time" and names no edition, and the Borough's Building Permits & Guidelines page says construction documents must show how the work conforms to "the IRC (International Residential Code) and IBC (International Building Code) of 2018"; this record has not read the 2018 edition's text and does not decide which edition the Borough applies.
