Adopted code

West Norriton Township - Building Department

Yes, a permit is required to replace a roof in Township of West Norriton, PA, issued by West Norriton Township - Building Department. West Norriton Township's Building Department says "Permits are required for all work except: painting, wallpapering, carpeting, and landscape work." Section 4-102.1 of the Township Code (as amended by Ord. 2016-705) says "Consistent with the Uniform Construction Code, building permits shall be required for, but not limited to, the constructing, enlarging, altering, removing, or demolishing of: A. Residential homes or dwellings;" and its list goes on to "Interior and exterior alterations to a residential or commercial structure, which include any type of structural, electrical, plumbing, mechanical or accessibility work." The clause names no roof work either way. The Building Department's page (read October 7, 2026) says "The Building Department oversees all construction and repairs to residential and commercial buildings. Building permits are required by law," and "Permits are required for all work except: painting, wallpapering, carpeting, and landscape work." Its Applications & Permits page lists "Construction - Including: all new construction, additions, alterations, decks, replacement windows, and demolitions" among work that requires a permit; neither page names roofing either way. The Township's construction permit application has a Roofing line among the contractors on the job. The fee schedule kept with the Township Code (last amended by Res. No. 23-1712, November 14, 2023) has no roofing line; it prices building permits by cost, "$0 to $2,000" at $50 and "Each additional $1,000 or part thereof" at $25. 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, the Building Department states that permits are required for all work except painting, wallpapering, carpeting and landscape work, so expect it to require a building permit for a reroof; the Township's fee schedule charges "2x normal permit fee" as the penalty for failing to obtain permits, at the discretion of the building code official. Building permit applications are available online or at the Township Office. The Township says home improvement contractors "must be licensed with the State of Pennsylvania and provide West Norriton Township with a certificate of insurance," and that commercial, electrical and plumbing contractors register with the Township. The office is open 8:30 a.m. to 4:30 p.m., Monday through Friday, at 610-631-0450. Read for this answer: Chapter 4 of the Township Code, Part 1, Building Code (Sections 4-101 to 4-103), in full, which is the Township's Uniform Construction Code ordinance and its permit provision; the fee schedule kept with the Township Code; Sections 4-302 and 4-311 of Part 3, Floodplain Regulations, whose permit clauses sit in the floodplain rules; every page of a search of the whole Township Code for "roof," which found no permit provision naming roof work; the Building & Zoning and Applications & Permits pages; and the construction permit 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, West Norriton Township administers the code itself: Section 4-101 of the Township Code says "This Township hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Township's Building Department, at 1630 W Marshall Street, under its Director of Code Enforcement, takes building permit applications; the Township's construction permit application says the application review is completed by Code Inspections, Inc. Section 4-102.1 adopts the Uniform Construction Code, "as amended from time to time," as the Municipal Building Code and lists work that needs a building permit; Chapter 4 changes nothing in the code's roofing provisions. Section 4-102.1 adopts the Uniform Construction Code "as amended from time to time" without naming an edition, and the Township's construction permit application says "Project design shall conform to the most current edition of the International Residential Code adopted by the Commonwealth of Pennsylvania."
Impact-resistant roofing
Not required — No impact-resistance requirement under state law. The State's adoption of the 2021 International Residential Code (34 Pa. Code 403.21) contains no hail or impact rule, and it makes no change to the code's roof assemblies chapter, which itself has no UL 2218, Class 4 or hail-impact requirement for roof coverings. A municipality could add one only by an ordinance that equals or exceeds the Uniform Construction Code under Act 45 section 503, filed with the Department of Labor and Industry; none of the filings on the Department's register of municipal code change ordinances mentions hail or impact resistance. An owner may still choose an impact-rated roof covering. Everything above is Pennsylvania state law, the same in every municipality. Locally, West Norriton Township administers the code itself: Section 4-101 of the Township Code says "This Township hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Township's Building Department, at 1630 W Marshall Street, under its Director of Code Enforcement, takes building permit applications; the Township's construction permit application says the application review is completed by Code Inspections, Inc. Part 1 of Chapter 4 of the Township Code, read in full, contains no UL 2218, Class 4 or hail-impact requirement. Section 4-102.1 adopts the Uniform Construction Code "as amended from time to time" without naming an edition, and the Township's construction permit application says "Project design shall conform to the most current edition of the International Residential Code adopted by the Commonwealth of Pennsylvania."
Repair permit threshold
West Norriton Township's own code requires building permits for altering residential homes, and its Building Department says permits are required for all work except painting, wallpapering, carpeting and landscape work. Section 4-102.1 of the Township Code (as amended by Ord. 2016-705) says "Consistent with the Uniform Construction Code, building permits shall be required for, but not limited to, the constructing, enlarging, altering, removing, or demolishing of: A. Residential homes or dwellings;" and its list goes on to "Interior and exterior alterations to a residential or commercial structure, which include any type of structural, electrical, plumbing, mechanical or accessibility work." The clause names no roof work either way. The Building Department's page (read October 7, 2026) says "The Building Department oversees all construction and repairs to residential and commercial buildings. Building permits are required by law," and "Permits are required for all work except: painting, wallpapering, carpeting, and landscape work." Its Applications & Permits page lists "Construction - Including: all new construction, additions, alterations, decks, replacement windows, and demolitions" among work that requires a permit; neither page names roofing either way. The Township's construction permit application has a Roofing line among the contractors on the job. The fee schedule kept with the Township Code (last amended by Res. No. 23-1712, November 14, 2023) has no roofing line; it prices building permits by cost, "$0 to $2,000" at $50 and "Each additional $1,000 or part thereof" at $25. 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, the Building Department states that permits are required for all work except painting, wallpapering, carpeting and landscape work, so expect it to require a building permit for a reroof; the Township's fee schedule charges "2x normal permit fee" as the penalty for failing to obtain permits, at the discretion of the building code official. 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, West Norriton Township administers the code itself: Section 4-101 of the Township Code says "This Township hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Township's Building Department, at 1630 W Marshall Street, under its Director of Code Enforcement, takes building permit applications; the Township's construction permit application says the application review is completed by Code Inspections, Inc. No Township text sets an area or cost threshold for roof work; the department's stated exceptions are painting, wallpapering, carpeting and landscape 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, West Norriton Township administers the code itself: Section 4-101 of the Township Code says "This Township hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Township's Building Department, at 1630 W Marshall Street, under its Director of Code Enforcement, takes building permit applications; the Township's construction permit application says the application review is completed by Code Inspections, Inc. Chapter 4 of the Township Code changes nothing in the code's reroofing provisions, and the Building Department's pages say nothing on roof layers; the department says permits are required for all work except painting, wallpapering, carpeting and landscape work.
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, West Norriton Township administers the code itself: Section 4-101 of the Township Code says "This Township hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Township's Building Department, at 1630 W Marshall Street, under its Director of Code Enforcement, takes building permit applications; the Township's construction permit application says the application review is completed by Code Inspections, Inc. Chapter 4 of the Township Code changes nothing in the code's roof sheathing provisions, and the Building Department's pages draw no separate line for roof sheathing.
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. West Norriton Township is in Montgomery County. The Township's permit pages and fee schedule say nothing on sales tax.

West Norriton Township's Building Department, at 1630 W Marshall Street, issues building permits, and its page says permits are required for all work except painting, wallpapering, carpeting and landscape work. 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."

Roofing questions: Township of West Norriton, PA

Do you need a permit to replace a roof in Township of West Norriton, PA?

Yes, a permit is required to replace a roof in Township of West Norriton, PA. West Norriton Township's own code requires building permits for altering residential homes, and its Building Department says permits are required for all work except painting, wallpapering, carpeting and landscape work. Section 4-102.1 of the Township Code (as amended by Ord. 2016-705) says "Consistent with the Uniform Construction Code, building permits shall be required for, but not limited to, the constructing, enlarging, altering, removing, or demolishing of: A. Residential homes or dwellings;" and its list goes on to "Interior and exterior alterations to a residential or commercial structure, which include any type of structural, electrical, plumbing, mechanical or accessibility work." The clause names no roof work either way. The Building Department's page (read October 7, 2026) says "The Building Department oversees all construction and repairs to residential and commercial buildings. Building permits are required by law," and "Permits are required for all work except: painting, wallpapering, carpeting, and landscape work." Its Applications & Permits page lists "Construction - Including: all new construction, additions, alterations, decks, replacement windows, and demolitions" among work that requires a permit; neither page names roofing either way. The Township's construction permit application has a Roofing line among the contractors on the job. The fee schedule kept with the Township Code (last amended by Res. No. 23-1712, November 14, 2023) has no roofing line; it prices building permits by cost, "$0 to $2,000" at $50 and "Each additional $1,000 or part thereof" at $25. 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, the Building Department states that permits are required for all work except painting, wallpapering, carpeting and landscape work, so expect it to require a building permit for a reroof; the Township's fee schedule charges "2x normal permit fee" as the penalty for failing to obtain permits, at the discretion of the building code official. 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."

Can you roof over an existing roof in Township of West Norriton, 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.

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.

Do roofing contractors need a license or registration in Township of West Norriton, PA?

Yes.

What building code does Township of West Norriton, 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.
