Whitemarsh Township - Building, Permitting & Licensing

Yes, a permit is required to replace a roof in Township of Whitemarsh, PA, issued by Whitemarsh Township - Building, Permitting & Licensing. Whitemarsh Township's building office requires a building permit to replace a roof. The Township's Building Permits page (read October 7, 2026) says "Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure" or its systems "shall first make application to the building official and obtain the required permit," and its list of "Examples of when permits are required" includes "Replacing a roof." The Permit Applications & Requirements page says "It is noted that a Zoning Permit Application is required for all Building Permit Applications, with the exception of roofing and siding projects." The Township's 2026 Building, Engineering, and Zoning Fees list a building permit fee for "Roofing and Siding and Stucco - RESIDENTIAL" of $60.00 for the first $5,000 of cost and $5.00 for each additional $1,000 or fraction, plus the $4.50 State fee, with "No Zoning Permit Required," and a separate fee for "Alterations, Structural Replacements and Repairs (includes Attic and Roof) - RESIDENTIAL." Chapter 42 of the Township Code, Article I, Uniform Construction Codes, names no roof work. Section 42-5.A says "Section 403-62(c) shall have the following items deleted from the list of permit exempt items" and lists nine items by number only; this record has not matched those numbers to the regulation's current list. In the Historic District, Section 10-9 says "The Building Inspector shall not issue a building permit for the alteration of all or part of any building or structure in the district until the Township Board of Supervisors has issued a certificate of appropriateness," and Section 10-3 counts "replacing a roof with like materials on a noncontributing building or structure" as a minor project the Building Inspector may approve without the review board. 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, apply for a building permit before replacing a house roof; a roofing job needs no separate zoning permit. The Building Permits page says "If you are unsure whether you need a permit for your project, please contact Whitemarsh Township Building and Codes Department or Planning and Zoning Department to inquire (610-825-3535)." Read for this answer: Chapter 42 of the Township Code, Building Construction (Article I, Uniform Construction Codes, and Article II, Floodplain Regulations; Sections 42-1 to 42-10), in full; Chapter 10, Historic District; a search of the whole Township Code for "roof" and for "reroofing"; the Township's Building, Permitting & Licensing, Building Permits, Permit Applications & Requirements and Residential Building Permit Requirements pages; and its 2026 Building, Engineering, and Zoning Fees. The office is open Monday to Friday, 8 a.m. to 4:30 p.m.

Permit process note
Whitemarsh Township's building office requires a building permit to replace a roof. The Township's Building Permits page (read October 7, 2026) says "Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure" or its systems "shall first make application to the building official and obtain the required permit," and its list of "Examples of when permits are required" includes "Replacing a roof." The Permit Applications & Requirements page says "It is noted that a Zoning Permit Application is required for all Building Permit Applications, with the exception of roofing and siding projects." The Township's 2026 Building, Engineering, and Zoning Fees list a building permit fee for "Roofing and Siding and Stucco - RESIDENTIAL" of $60.00 for the first $5,000 of cost and $5.00 for each additional $1,000 or fraction, plus the $4.50 State fee, with "No Zoning Permit Required," and a separate fee for "Alterations, Structural Replacements and Repairs (includes Attic and Roof) - RESIDENTIAL." Chapter 42 of the Township Code, Article I, Uniform Construction Codes, names no roof work. Section 42-5.A says "Section 403-62(c) shall have the following items deleted from the list of permit exempt items" and lists nine items by number only; this record has not matched those numbers to the regulation's current list. In the Historic District, Section 10-9 says "The Building Inspector shall not issue a building permit for the alteration of all or part of any building or structure in the district until the Township Board of Supervisors has issued a certificate of appropriateness," and Section 10-3 counts "replacing a roof with like materials on a noncontributing building or structure" as a minor project the Building Inspector may approve without the review board. 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, apply for a building permit before replacing a house roof; a roofing job needs no separate zoning permit. The Building Permits page says "If you are unsure whether you need a permit for your project, please contact Whitemarsh Township Building and Codes Department or Planning and Zoning Department to inquire (610-825-3535)." Read for this answer: Chapter 42 of the Township Code, Building Construction (Article I, Uniform Construction Codes, and Article II, Floodplain Regulations; Sections 42-1 to 42-10), in full; Chapter 10, Historic District; a search of the whole Township Code for "roof" and for "reroofing"; the Township's Building, Permitting & Licensing, Building Permits, Permit Applications & Requirements and Residential Building Permit Requirements pages; and its 2026 Building, Engineering, and Zoning Fees. The office is open Monday to Friday, 8 a.m. to 4:30 p.m.
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, Whitemarsh Township administers the code itself: Section 42-2 of the Township Code says "the Township of Whitemarsh, situate in Montgomery County, Pennsylvania, hereby elects to administer and enforce the Uniform Construction Code as its municipal building code," and the Township's Building Permits page sends permit applications to the building official at Whitemarsh Township Building & Permits, 616 Germantown Pike, Lafayette Hill. Section 42-5.C fills in Table R301.2(1) with design data, including "Ice shield: NO," and changes nothing in the code's roofing provisions. Section 42-3 of the Township Code adopts appendixes "to the International Residential Code 2003" and says "all subsequent editions or successor codes are hereby adopted," and the Township's pages name no residential code edition; this record has not read the 2003 edition's text and does not decide which edition the Township applies.
Repair permit threshold
Whitemarsh Township lists replacing a roof as permit work and charges a residential roofing fee. The Township's Building Permits page (read October 7, 2026) says "Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure" or its systems "shall first make application to the building official and obtain the required permit," and its list of "Examples of when permits are required" includes "Replacing a roof." The Permit Applications & Requirements page says "It is noted that a Zoning Permit Application is required for all Building Permit Applications, with the exception of roofing and siding projects." The Township's 2026 Building, Engineering, and Zoning Fees list a building permit fee for "Roofing and Siding and Stucco - RESIDENTIAL" of $60.00 for the first $5,000 of cost and $5.00 for each additional $1,000 or fraction, plus the $4.50 State fee, with "No Zoning Permit Required," and a separate fee for "Alterations, Structural Replacements and Repairs (includes Attic and Roof) - RESIDENTIAL." Chapter 42 of the Township Code, Article I, Uniform Construction Codes, names no roof work. Section 42-5.A says "Section 403-62(c) shall have the following items deleted from the list of permit exempt items" and lists nine items by number only; this record has not matched those numbers to the regulation's current list. In the Historic District, Section 10-9 says "The Building Inspector shall not issue a building permit for the alteration of all or part of any building or structure in the district until the Township Board of Supervisors has issued a certificate of appropriateness," and Section 10-3 counts "replacing a roof with like materials on a noncontributing building or structure" as a minor project the Building Inspector may approve without the review board. 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). 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, Whitemarsh Township administers the code itself: Section 42-2 of the Township Code says "the Township of Whitemarsh, situate in Montgomery County, Pennsylvania, hereby elects to administer and enforce the Uniform Construction Code as its municipal building code," and the Township's Building Permits page sends permit applications to the building official at Whitemarsh Township Building & Permits, 616 Germantown Pike, Lafayette Hill. The Township sets no area or cost threshold for roof work: its Building Permits page lists replacing a roof without a size limit, and Chapter 42 sets none.
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, Whitemarsh Township administers the code itself: Section 42-2 of the Township Code says "the Township of Whitemarsh, situate in Montgomery County, Pennsylvania, hereby elects to administer and enforce the Uniform Construction Code as its municipal building code," and the Township's Building Permits page sends permit applications to the building official at Whitemarsh Township Building & Permits, 616 Germantown Pike, Lafayette Hill. Chapter 42 of the Township Code changes nothing in the code's reroofing provisions, and the Township's pages say nothing on roof layers. Section 42-3 of the Township Code adopts appendixes "to the International Residential Code 2003" and says "all subsequent editions or successor codes are hereby adopted," and the Township's pages name no residential code edition; the text above is the 2021 edition's, and the 2003 edition's reroofing text was not read for this record, and this record does not decide which edition the Township 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, Whitemarsh Township administers the code itself: Section 42-2 of the Township Code says "the Township of Whitemarsh, situate in Montgomery County, Pennsylvania, hereby elects to administer and enforce the Uniform Construction Code as its municipal building code," and the Township's Building Permits page sends permit applications to the building official at Whitemarsh Township Building & Permits, 616 Germantown Pike, Lafayette Hill. Chapter 42 of the Township Code changes nothing in the code's roof sheathing provisions. The Township's 2026 fees price "Roofing and Siding and Stucco - RESIDENTIAL" apart from "Alterations, Structural Replacements and Repairs (includes Attic and Roof) - RESIDENTIAL"; neither draws a separate line for roof sheathing. Section 42-3 of the Township Code adopts appendixes "to the International Residential Code 2003" and says "all subsequent editions or successor codes are hereby adopted," and the Township's pages name no residential code edition; the text above is the 2021 edition's, and the 2003 edition's sheathing text was not read for this record, and this record does not decide which edition the Township 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. Whitemarsh Township is in Montgomery County. The Township's permit pages and 2026 fee list say nothing on sales tax.

Whitemarsh Township's building and codes office, at 616 Germantown Pike, Lafayette Hill, issues building permits; its Building Permits page lists replacing a roof among work that needs a permit, and its 2026 fee list has a residential roofing fee. 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 Whitemarsh, PA

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

Yes, a permit is required to replace a roof in Township of Whitemarsh, PA. Whitemarsh Township lists replacing a roof as permit work and charges a residential roofing fee. The Township's Building Permits page (read October 7, 2026) says "Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure" or its systems "shall first make application to the building official and obtain the required permit," and its list of "Examples of when permits are required" includes "Replacing a roof." The Permit Applications & Requirements page says "It is noted that a Zoning Permit Application is required for all Building Permit Applications, with the exception of roofing and siding projects." The Township's 2026 Building, Engineering, and Zoning Fees list a building permit fee for "Roofing and Siding and Stucco - RESIDENTIAL" of $60.00 for the first $5,000 of cost and $5.00 for each additional $1,000 or fraction, plus the $4.50 State fee, with "No Zoning Permit Required," and a separate fee for "Alterations, Structural Replacements and Repairs (includes Attic and Roof) - RESIDENTIAL." Chapter 42 of the Township Code, Article I, Uniform Construction Codes, names no roof work. Section 42-5.A says "Section 403-62(c) shall have the following items deleted from the list of permit exempt items" and lists nine items by number only; this record has not matched those numbers to the regulation's current list. In the Historic District, Section 10-9 says "The Building Inspector shall not issue a building permit for the alteration of all or part of any building or structure in the district until the Township Board of Supervisors has issued a certificate of appropriateness," and Section 10-3 counts "replacing a roof with like materials on a noncontributing building or structure" as a minor project the Building Inspector may approve without the review board. 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). 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, Whitemarsh Township administers the code itself: Section 42-2 of the Township Code says "the Township of Whitemarsh, situate in Montgomery County, Pennsylvania, hereby elects to administer and enforce the Uniform Construction Code as its municipal building code," and the Township's Building Permits page sends permit applications to the building official at Whitemarsh Township Building & Permits, 616 Germantown Pike, Lafayette Hill. The Township sets no area or cost threshold for roof work: its Building Permits page lists replacing a roof without a size limit, and Chapter 42 sets none.

Can you roof over an existing roof in Township of Whitemarsh, 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, Whitemarsh Township administers the code itself: Section 42-2 of the Township Code says "the Township of Whitemarsh, situate in Montgomery County, Pennsylvania, hereby elects to administer and enforce the Uniform Construction Code as its municipal building code," and the Township's Building Permits page sends permit applications to the building official at Whitemarsh Township Building & Permits, 616 Germantown Pike, Lafayette Hill. Chapter 42 of the Township Code changes nothing in the code's reroofing provisions, and the Township's pages say nothing on roof layers. Section 42-3 of the Township Code adopts appendixes "to the International Residential Code 2003" and says "all subsequent editions or successor codes are hereby adopted," and the Township's pages name no residential code edition; the text above is the 2021 edition's, and the 2003 edition's reroofing text was not read for this record, and this record does not decide which edition the Township applies.

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

Yes.

What building code does Township of Whitemarsh, 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, Whitemarsh Township administers the code itself: Section 42-2 of the Township Code says "the Township of Whitemarsh, situate in Montgomery County, Pennsylvania, hereby elects to administer and enforce the Uniform Construction Code as its municipal building code," and the Township's Building Permits page sends permit applications to the building official at Whitemarsh Township Building & Permits, 616 Germantown Pike, Lafayette Hill. Section 42-5.C fills in Table R301.2(1) with design data, including "Ice shield: NO," and changes nothing in the code's roofing provisions. Section 42-3 of the Township Code adopts appendixes "to the International Residential Code 2003" and says "all subsequent editions or successor codes are hereby adopted," and the Township's pages name no residential code edition; this record has not read the 2003 edition's text and does not decide which edition the Township applies.
