Adopted code

Doylestown Borough - Department of Building and Zoning

Yes, a permit is required to replace a roof in Borough of Doylestown, PA, issued by Doylestown Borough - Department of Building and Zoning. Doylestown Borough requires a Roof or Window permit to replace a roof on a house. The Borough's Windows and Roofing Replacement page (read October 9, 2026) says "Replacement of a roof or windows requires a Roof or Window permit" and "No Permit is required when an area of less than 20% of the roof is being re-roofed or repaired." Its permit page lists "Window or roof replacement" among "Common projects needing permits," and the Borough's 2026 fee schedule (approved August 17, 2026) has a line "5. ROOFING" with "Residential: (repair and/or replacement) $50.00." The same page says "Installation, replacement or major repair of any structural component of roof or window structures (trusses, headers, rafters, etc.) for existing buildings requires a Building Permit." In the historic district, the page adds: "If you are located in the historic district and you are making changes to the exterior of your property that can be seen from the street and exceed $2,000 please review the HARB Certificate of Appropriateness requirements," and the application says that process comes first. 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). In practice, expect the Borough to require a roof permit and a final inspection for a reroof on a house. The page says "Failure to secure a permit when necessary may result in violations, fines and necessitate the removal of installed structures," and the fee schedule says that where construction starts without the required permits "the applicable fees will be increased by 100%." Section 105 of Chapter 5 keeps in force Borough code provisions adopted on or before July 1, 1999 that equal or exceed the code, "including policies implemented thereunder," and names none. Bring two copies of the Replacement Roof/Window Application with plans and manufacturer specifications and payment to the Borough office at 10 Doyle Street, Doylestown, 215-345-4140, open Monday to Friday 8:30 a.m. to 4:30 p.m.; the application says review "normally takes 7 – 10 days but may be as long as 20 days." Read for this answer: Part 1 of Chapter 5 of the Borough Code, Uniform Construction Code (Sections 101 to 106), in full; Chapter 4, Buildings (numbering and the historic district); every page of a search of the whole Borough Code for "roof" and for "reroofing"; the Borough's permit page, Windows and Roofing Replacement page, roof and window permit application and 2026 fee schedule.

Permit process note
Doylestown Borough requires a Roof or Window permit to replace a roof on a house. The Borough's Windows and Roofing Replacement page (read October 9, 2026) says "Replacement of a roof or windows requires a Roof or Window permit" and "No Permit is required when an area of less than 20% of the roof is being re-roofed or repaired."

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). In practice, expect the Borough to require a roof permit and a final inspection for a reroof on a house. The page says "Failure to secure a permit when necessary may result in violations, fines and necessitate the removal of installed structures," and the fee schedule says that where construction starts without the required permits "the applicable fees will be increased by 100%." Section 105 of Chapter 5 keeps in force Borough code provisions adopted on or before July 1, 1999 that equal or exceed the code, "including policies implemented thereunder," and names none. Bring two copies of the Replacement Roof/Window Application with plans and manufacturer specifications and payment to the Borough office at 10 Doyle Street, Doylestown, 215-345-4140, open Monday to Friday 8:30 a.m. to 4:30 p.m.; the application says review "normally takes 7 – 10 days but may be as long as 20 days." Read for this answer: Part 1 of Chapter 5 of the Borough Code, Uniform Construction Code (Sections 101 to 106), in full; Chapter 4, Buildings (numbering and the historic district); every page of a search of the whole Borough Code for "roof" and for "reroofing"; the Borough's permit page, Windows and Roofing Replacement page, roof and window permit application and 2026 fee schedule.
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, Doylestown Borough administers the code itself: Section 102 of Chapter 5 of the Borough Code says the Borough "hereby elects to administer and enforce" the Act and adopts the Uniform Construction Code "as amended from time to time" as the Building Code of the Borough, and the Borough's roof and window permit application says "The Borough of Doylestown requires that prior to any roof or window replacement the property owner shall acquire a Permit from the Department of Building and Zoning, located at 10 Doyle Street." Chapter 5 changes nothing in the code's roofing provisions. Section 105 of Chapter 5 keeps in force Borough code provisions adopted on or before July 1, 1999 that equal or exceed the code, "including policies implemented thereunder," and names none. The Borough's roofing pages name only International Building Code editions (the Windows and Roofing Replacement page says work must meet "the 2018 International Building (IBC)" and the roof and window permit application names "the PAUCC and IBC 2015") and name no residential code edition; the text above is the 2021 edition's, the older editions' text was not read for this record, and this record does not decide which edition the Borough applies.
Repair permit threshold
Doylestown Borough requires a Roof or Window permit to replace a roof; only work on less than 20% of the roof needs none. The Borough's Windows and Roofing Replacement page (read October 9, 2026) says "Replacement of a roof or windows requires a Roof or Window permit" and "No Permit is required when an area of less than 20% of the roof is being re-roofed or repaired." Its permit page lists "Window or roof replacement" among "Common projects needing permits," and the Borough's 2026 fee schedule (approved August 17, 2026) has a line "5. ROOFING" with "Residential: (repair and/or replacement) $50.00." The same page says "Installation, replacement or major repair of any structural component of roof or window structures (trusses, headers, rafters, etc.) for existing buildings requires a Building Permit." In the historic district, the page adds: "If you are located in the historic district and you are making changes to the exterior of your property that can be seen from the street and exceed $2,000 please review the HARB Certificate of Appropriateness requirements," and the application says that process comes first. 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). In practice, expect the Borough to require a roof permit and a final inspection for a reroof on a house. The page says "Failure to secure a permit when necessary may result in violations, fines and necessitate the removal of installed structures," and the fee schedule says that where construction starts without the required permits "the applicable fees will be increased by 100%." 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, Doylestown Borough administers the code itself: Section 102 of Chapter 5 of the Borough Code says the Borough "hereby elects to administer and enforce" the Act and adopts the Uniform Construction Code "as amended from time to time" as the Building Code of the Borough, and the Borough's roof and window permit application says "The Borough of Doylestown requires that prior to any roof or window replacement the property owner shall acquire a Permit from the Department of Building and Zoning, located at 10 Doyle Street." The Borough's threshold, quoted at the start, is area-based: no permit where "an area of less than 20% of the roof is being re-roofed or repaired"; a full reroof is over that line.
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, Doylestown Borough administers the code itself: Section 102 of Chapter 5 of the Borough Code says the Borough "hereby elects to administer and enforce" the Act and adopts the Uniform Construction Code "as amended from time to time" as the Building Code of the Borough, and the Borough's roof and window permit application says "The Borough of Doylestown requires that prior to any roof or window replacement the property owner shall acquire a Permit from the Department of Building and Zoning, located at 10 Doyle Street." Chapter 5 of the Borough Code changes nothing in the code's reroofing provisions. The Borough's Windows and Roofing Replacement page states its own rule: "A maximum of two (2) asphalt, fiberglass, or low slope roofing systems are permitted. A new roof MAY NOT be installed over any of the following systems: slate, wood shake, asbestos or clay tile." The Borough's roofing pages name only International Building Code editions (the Windows and Roofing Replacement page says work must meet "the 2018 International Building (IBC)" and the roof and window permit application names "the PAUCC and IBC 2015") and name no residential code edition; the text above is the 2021 edition's, the older editions' 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, Doylestown Borough administers the code itself: Section 102 of Chapter 5 of the Borough Code says the Borough "hereby elects to administer and enforce" the Act and adopts the Uniform Construction Code "as amended from time to time" as the Building Code of the Borough, and the Borough's roof and window permit application says "The Borough of Doylestown requires that prior to any roof or window replacement the property owner shall acquire a Permit from the Department of Building and Zoning, located at 10 Doyle Street." Chapter 5 of the Borough Code changes nothing in the code's roof sheathing provisions. The Borough's Windows and Roofing Replacement page says "Roof sheathing must be a minimum 1/2” sheathing when installed over rafters 16” on center. All rafters more than 16” apart require a minimum of 5/8” roof sheathing with H clips," and that structural roof work needs a Building Permit. The Borough's roofing pages name only International Building Code editions (the Windows and Roofing Replacement page says work must meet "the 2018 International Building (IBC)" and the roof and window permit application names "the PAUCC and IBC 2015") and name no residential code edition; the text above is the 2021 edition's, the older editions' 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. Doylestown Borough is in Bucks County. The Borough's permit pages and fee schedule say nothing on sales tax.

Roofing questions: Borough of Doylestown, PA

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

Yes, a permit is required to replace a roof in Borough of Doylestown, PA. Doylestown Borough requires a Roof or Window permit to replace a roof; only work on less than 20% of the roof needs none. The Borough's Windows and Roofing Replacement page (read October 9, 2026) says "Replacement of a roof or windows requires a Roof or Window permit" and "No Permit is required when an area of less than 20% of the roof is being re-roofed or repaired." Its permit page lists "Window or roof replacement" among "Common projects needing permits," and the Borough's 2026 fee schedule (approved August 17, 2026) has a line "5. ROOFING" with "Residential: (repair and/or replacement) $50.00." The same page says "Installation, replacement or major repair of any structural component of roof or window structures (trusses, headers, rafters, etc.) for existing buildings requires a Building Permit." In the historic district, the page adds: "If you are located in the historic district and you are making changes to the exterior of your property that can be seen from the street and exceed $2,000 please review the HARB Certificate of Appropriateness requirements," and the application says that process comes first. 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). In practice, expect the Borough to require a roof permit and a final inspection for a reroof on a house. The page says "Failure to secure a permit when necessary may result in violations, fines and necessitate the removal of installed structures," and the fee schedule says that where construction starts without the required permits "the applicable fees will be increased by 100%." 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, Doylestown Borough administers the code itself: Section 102 of Chapter 5 of the Borough Code says the Borough "hereby elects to administer and enforce" the Act and adopts the Uniform Construction Code "as amended from time to time" as the Building Code of the Borough, and the Borough's roof and window permit application says "The Borough of Doylestown requires that prior to any roof or window replacement the property owner shall acquire a Permit from the Department of Building and Zoning, located at 10 Doyle Street." The Borough's threshold, quoted at the start, is area-based: no permit where "an area of less than 20% of the roof is being re-roofed or repaired"; a full reroof is over that line.

Can you roof over an existing roof in Borough of Doylestown, 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, Doylestown Borough administers the code itself: Section 102 of Chapter 5 of the Borough Code says the Borough "hereby elects to administer and enforce" the Act and adopts the Uniform Construction Code "as amended from time to time" as the Building Code of the Borough, and the Borough's roof and window permit application says "The Borough of Doylestown requires that prior to any roof or window replacement the property owner shall acquire a Permit from the Department of Building and Zoning, located at 10 Doyle Street." Chapter 5 of the Borough Code changes nothing in the code's reroofing provisions. The Borough's Windows and Roofing Replacement page states its own rule: "A maximum of two (2) asphalt, fiberglass, or low slope roofing systems are permitted. A new roof MAY NOT be installed over any of the following systems: slate, wood shake, asbestos or clay tile." The Borough's roofing pages name only International Building Code editions (the Windows and Roofing Replacement page says work must meet "the 2018 International Building (IBC)" and the roof and window permit application names "the PAUCC and IBC 2015") and name no residential code edition; the text above is the 2021 edition's, the older editions' 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 Doylestown, PA?

Yes.

What building code does Borough of Doylestown, 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, Doylestown Borough administers the code itself: Section 102 of Chapter 5 of the Borough Code says the Borough "hereby elects to administer and enforce" the Act and adopts the Uniform Construction Code "as amended from time to time" as the Building Code of the Borough, and the Borough's roof and window permit application says "The Borough of Doylestown requires that prior to any roof or window replacement the property owner shall acquire a Permit from the Department of Building and Zoning, located at 10 Doyle Street." Chapter 5 changes nothing in the code's roofing provisions. Section 105 of Chapter 5 keeps in force Borough code provisions adopted on or before July 1, 1999 that equal or exceed the code, "including policies implemented thereunder," and names none. The Borough's roofing pages name only International Building Code editions (the Windows and Roofing Replacement page says work must meet "the 2018 International Building (IBC)" and the roof and window permit application names "the PAUCC and IBC 2015") and name no residential code edition; the text above is the 2021 edition's, the older editions' text was not read for this record, and this record does not decide which edition the Borough applies.
