Roofing in Downingtown, Pennsylvania

Yes, a permit is required to replace a roof in Downingtown, PA, issued by Borough of Downingtown - Code Enforcement Office. Downingtown Borough's code requires a permit for the replacement or reshingling of more than 25% of a roof, and the Borough publishes its own Roof Permit Application. Section 120-8 of the Borough Code (added by Ord. No. 2013-07, December 4, 2013, amended by Ord. No. 2025-03, August 6, 2025; read October 9, 2026) says that, "In addition to all types of construction, placement of structures, repairs, and alterations for which the Uniform Construction Code requires a permit, the Borough pursuant to the authorization of Act 92 of 2004 shall require persons to obtain permits under the Borough of Downingtown Construction Code" for, among other work, "The replacement or reshingling of more than 25% of the total existing roof square footage." A full reroof is above that line. The Borough's Code Enforcement page (read October 9, 2026) says "Examples of work requiring building permits to the exterior of an existing building include replacement of roof shingles," and the Borough publishes a dedicated Roof Permit Application (revised January 2025) whose addendum "must be completed by every applicant seeking a permit to replace or repair a roof in Downingtown Borough," with a residential application fee of $75, a residential permit fee of $110.00 and a PA State L&I fee of $4.50. Under state law, Act 45 says the Act "shall not apply to" "Alterations to residential buildings which do not make structural changes or changes to means of egress, except as might be required by ordinances in effect pursuant to section 303(b)(1) or adopted pursuant to section 503" or to "Repairs to residential buildings, except as might be required by ordinances in effect pursuant to section 303(b)(1) or adopted pursuant to section 503" (section 104(b)(5) and (6)), and of a municipal ordinance that adds to the code, section 503(c) says "An ordinance under this subsection shall not be effective nor enforceable unless subsections (d), (e), (f), (g), (h) and (i) have been satisfied." This record does not decide whether the municipality's requirement is one adopted under section 503 or kept in effect by section 303(b)(1). The Department of Labor and Industry's register of municipal code change ordinances lists a Downingtown Borough filing that included "Requiring a permit for the replacement or re-shingling of any residential roof"; some of its changes were found not to be in compliance and a disapproval letter was mailed September 5, 2013, and after it was "Resubmitted with revision" the changes were found to be in compliance with an approval letter mailed October 24, 2013. In practice, expect the Borough to require a permit for a reroof of more than 25% of the roof. The Roof Permit Application says "All permits must be obtained prior to the start of work and must be posted in a conspicuous place where they can be seen from a public way," and Section 120-10 sets a fine "of not more than $1,000 plus court costs" on conviction, with each day a violation continues a separate offense. Applications may be mailed to or dropped off at the Code Enforcement Office, 4-10 W. Lancaster Avenue, Downingtown, PA 19335, and are processed once the application fee has been received; the Borough says residential permits have 15 business days for review. The office is open Monday to Friday, 8 a.m. to 4 p.m., at 610-269-0344.

Roofing permits & building code in Downingtown

Roofing permit and contractor-licensing rules in Downingtown are set locally by Borough of Downingtown - Code Enforcement Office. Pennsylvania issues no state roofing licence, but its Home Improvement Consumer Protection Act requires a contractor to register with the Attorney General’s Bureau of Consumer Protection before doing home improvement work, which the Act defines to include roofs on jobs over $500, unless the contractor’s home improvement work totalled less than $5,000 in the previous tax year — and the Uniform Construction Code applies to buildings throughout the Commonwealth as a minimum a municipality may exceed but not fall below, with ordinary repairs to a house outside it unless a local ordinance brings them in, so whether a reroof needs a permit is a municipal question — always confirm the current requirements with the authority before starting work.

Required
Adopted building 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, Downingtown Borough administers the Uniform Construction Code itself: Section 120-1 of the Borough Code says "The Borough of Downingtown hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Borough's Code Enforcement Office at 4-10 W. Lancaster Avenue, staffed by a Director of Building, code enforcement officers and a building code official, issues the permits. Section 120-1 (amended by Ord. No. 2023-02) adopts the Act and "its regulations now contained in 34 Pa. Code Chapters 401 to 405, as amended from time to time," and names no residential code edition; the Borough's Code Enforcement page names none either. Chapter 120 changes nothing in the code's roofing provisions.
Registration details
  • state_level: Home Improvement Consumer Protection Act, Act 132 of 2008, 73 P.S. 517.1 et seq.: registration with the Attorney General's Bureau of Consumer Protection before performing any home improvement over $500 (section 2, section 3(a)); persons whose home improvements totalled less than $5,000 in the previous taxable year are not "contractors" (section 2). Section 12 precludes local registration or licensing of home improvement contractors, with carve-outs for building permits, pre-existing tested trade licences, and local insurance standards adopted before January 1, 2006.
  • city_level: Chapter 121 of the Borough Code (Ord. No. 90-6, May 9, 1990) requires persons acting as, among others, "home improvement contractors or subcontractors, roofing contractors" to "obtain a license from the Borough," renewed each license year beginning July 1, with a certificate of insurance of at least $100,000 per occurrence and aggregate (Section 121-9A). The Borough's Roof Permit Application says sub-contractors "must be license with Downingtown Borough OR registered as a Home Improvement Contractor (HIC) with the State of PA (HIC for residential roofing only)." This record does not decide how section 12 of the state Act bears on Chapter 121.
