Collin County - Development Services
No — Collin County, TX does not require a permit for like-for-like roof replacement (Collin County - Development Services). Collin County's FAQ states: "Do Contractors need to register to do work within Collin County's permitting jurisdiction? No, contractors do not need to register with Collin County to do work within the County's jurisdiction." On residential permitting, the FAQ states: "Only projects that will result in disturbance of ground or addition of footprint on a parcel of land will require a permit (for example - a new structure, an addition, swimming pools, fencing, grading/ filling, a new pond, etc.) or an extensive remodel of a dwelling structure that adds a bedroom or otherwise doubles the value of the structure require permitting." It continues: "Permits are not required for projects like: re-roofing, new electrical service on an existing structure, roof-mounted solar panels, water heater or AC unit change out, etc." The FAQ notes that both unincorporated and ETJ properties are always within the county's permitting jurisdiction and that the county does not have zoning in unincorporated areas except for sexually-oriented businesses, salvage/junk yards, and animal slaughter operations. Separately, new residential construction is subject to a state-authorized notice-and-inspection program: a third-party inspector (a licensed engineer, registered architect, Texas Real Estate Commission-licensed inspector, or ICC-certified residential combination inspector, among others) must perform at least three inspections - foundation stage before concrete placement, framing/mechanical stage before drywall, and on completion - after which the builder must submit a notice of passing inspection to Development Services within 10 days of the final inspection.

Adopted code
Collin County adopts no code edition of its own. For new single-family and duplex construction in the unincorporated county, Tex. Loc. Gov't Code § 233.153(a) requires conformance to "the version of the International Residential Code published as of May 1, 2008, or the version of the International Residential Code that is applicable in the county seat of that county." The county seat is McKinney, whose currently adopted codes are the 2024 International Codes, effective October 1, 2025 (mckinneytexas.org/243/Building-Inspections). The county operates under this subchapter: it administers the § 233.154 third-party notice-and-inspection program, and its own "Building Code Information" document (2013) restates the pointer — residential structures "Must comply with adopted codes for the County Seat." Per the statute, this reaches NEW residential construction only (the county neither permits nor inspects re-roofing), and inside a municipality's extraterritorial jurisdiction that has adopted its own building code, the municipal code controls instead (§ 233.153(c)).
Impact-resistant roofing
Not required — Collin County has adopted no residential building code for unincorporated areas and does not permit or inspect re-roofing, so no Class 4 impact-resistance requirement can attach. The county's own Development Services FAQ states that re-roofing does not require a county permit and that "Only projects that will result in ground disturbance" are permitted.
Sales & use tax
Texas Comptroller's list of the 125 counties that impose a Chapter 323 county sales and use tax does not include Collin County; Collin County levies no general county sales and use tax (comptroller.texas.gov/taxes/sales/county.php). No special-purpose district or emergency services district in Collin County is coextensive with the whole unincorporated county the way a county-wide district would be -- the district-level list shows only isolated municipal-development and crime/fire-control districts tied to specific incorporated cities' boundaries or extraterritorial jurisdictions (comptroller.texas.gov/taxes/sales/spd.php). In unincorporated Collin County outside any such district, the combined rate is therefore 6.25% (state only). Texas collects no construction use tax at building-permit issuance; use tax, when owed, is self-assessed by the purchaser and remitted directly to the Comptroller's office rather than collected by a city or county permit office (Comptroller Use Tax guidance, comptroller.texas.gov/taxes/sales/use-tax.php). Under Comptroller guidance for real property repair and remodeling, "Labor to repair, remodel, or restore residential real property is not taxable"; on the lump-sum contract typical of residential re-roofing, "you pay tax on all your supplies, materials, equipment, and taxable services when you buy them. You don't charge your customer tax" (Comptroller Pub. 94-116, Real Property Repair and Remodeling, comptroller.texas.gov/taxes/publications/94-116.php) -- so the combined rate above is the roofer's own cost basis on materials purchased, not a rate charged to the homeowner.
The permitting authority for unincorporated areas and extraterritorial jurisdictions (ETJ) of Collin County, Texas. Development Services issues permits for ground-disturbing residential and commercial projects and on-site sewage facilities (OSSF), and administers the county's state-authorized notice-and-inspection program for new residential construction. Its own FAQ states that re-roofing does not require a county permit and that contractors are not required to register with the county.
