Permit process note
"Dallas County issues permits only for properties located in the unincorporated areas of Dallas County. If your project or property is located within the city limits of a municipality, you must contact that city directly for permitting requirements and applications." DUAS's own list of applications includes a "Building Permit Application," described as "Required for the construction of new commercial buildings, including offices, warehouses, workshops, garages, and similar structures," and a separate "Notice of Residential Construction Application," described as "Required for new residential construction, additions, and major structural renovations." The same list also covers Addressing, Communications Facilities, Development Permit/Floodplain Development, Driveway/ Culvert, Mobile Home Placement, Right-of-Way/Utility, and Special Event permits, among others; re-roofing is not listed among the county's permit categories. All permits are applied for online through the county's MyGov customer portal.
Impact-resistant roofing
Not required — Dallas County issues building permits in unincorporated areas only for new commercial construction, plus a separate notice process for new residential construction; it adopts no residential building code governing re-roofing and issues no re-roof permits, so no Class 4 impact-resistance requirement can attach.
Sales & use tax
Texas Comptroller's list of the 125 counties that impose a Chapter 323 county sales and use tax does not include Dallas County; Dallas 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 Dallas 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 Dallas 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.
