Permit process note
"To have your roof replaced, the homeowner must obtain a permit and roof replacement or recovering must comply with the Town's currently adopted codes."
Adopted code
Effective October 1, 2025, the Town of Flower Mound's Construction Codes page lists, for residential construction, the 2024 International Residential Code, 2024 International Energy Conservation Code, and 2024 International Swimming Pool and Spa Code, plus the 2023 National Electrical Code; for commercial construction, the 2024 International Building Code, 2024 International Energy Conservation Code, 2024 International Mechanical Code, 2024 International Plumbing Code, and 2024 International Swimming Pool and Spa Code, plus the 2023 National Electrical Code. The Town maintains a separate local-amendments document referenced from the same page.
Drip edge
Required — Drip edge is required at eaves and rake edges of shingle roofs (IRC R905.2.8.5). The jurisdiction adopted the 2024 International Residential Code via the Town's Local Code Amendments, Exhibit F; that instrument, read in full, does not amend R905.2.8.5, so the code's drip-edge requirement stands as enacted local law. About drip edge
Ice & water shield
Not required — Table R301.2(1) "Climatic and Geographic Design Criteria," as amended by Exhibit F (Local Amendments to the 2024 International Residential Code) to the Town of Flower Mound's adopted-code ordinance, lists "No" in the Ice Barrier Under-Layment column (alongside Winter Design Temp 22°F, Air Freezing Index 150, Ground Snow Load 9 lb/ft). About ice & water barrier
Impact-resistant roofing
Not required — The Town of Flower Mound "Local Code Amendments", Exhibits A through G (2024 IBC, IPC/IFGC, IMC, 2023 NEC, ISPSC, 2024 IRC, IECC), contain no UL 2218, Class 4 impact rating, or hail provision across any of the seven exhibits. Exhibit F item (ee) amends R902.1 by adding only an exception exempting detached accessory structures of 120 sq ft or less from classified-roofing requirements; the Class A/B/C fire requirement is otherwise unchanged.
Wind design criteria
105 mph (3-second gust), measured at 33 feet above ground, Exposure Category C; topographic effects No, special wind region No, windborne debris zone No (Table R301.2(1) of the 2024 International Residential Code as amended by subsection (q) of the Town of Flower Mound's Local Code Amendments, Exhibit F to the adopted-code ordinance). Ground snow load 9 lb/ft².
Sales & use tax
8.25% combined (6.25% state + 1.50% Town of Flower Mound + 0.25% Flower Mound Crime Control and Prevention District + 0.25% Flower Mound Fire Control, Prevention, and EMS District), the Texas local-rate cap. 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.
