Do you need a permit to replace a roof in Austin, TX?
Adopted codeCity of Austin Development Services Department (DSD)
No — Austin, TX does not require a permit for like-for-like roof replacement (City of Austin Development Services Department (DSD)). The city's "Work Exempt from Building Permits" page exempts "[a]sphalt shingles that replace existing asphalt shingles" and "[r]eplacement of any roof covering that does not adversely affect the roof structure" — but only "unless the property is located in the Wildland-Urban Interface area and 50% or more of the roofing is being replaced." Outside the WUI, or below the 50% threshold, ordinary shingle-for- shingle reroofing does not require a permit; inside the WUI at 50%+ replacement, or for any roof-covering change that does affect the roof structure (material change, pitch change), a permit is required.

Registration details
- license: Per Austin Development Services' contractor-registration guidance: "Trade contractors, general contractors, and homeowners acting as contractors must be registered as a Contractor with Building and Trade Contractor Services" before a permit can be activated. General contractors register once and update only on a name/address/agent change; trade contractors renew annually. The department's published guidance does not name "roofing" as a distinct trade-registration category the way it names MEP trades — a roofing contractor most likely registers under the general-contractor category, but the city does not say so explicitly, so confirm the category with Building and Trade Contractor Services before registering. The department's contractor-registration page does not publish fee or insurance/bond minimums.
Permit process note
The city's "Work Exempt from Building Permits" page exempts "[a]sphalt shingles that replace existing asphalt shingles" and "[r]eplacement of any roof covering that does not adversely affect the roof structure" — but only "unless the property is located in the Wildland-Urban Interface area and 50% or more of the roofing is being replaced." Outside the WUI, or below the 50% threshold, ordinary shingle-for- shingle reroofing does not require a permit; inside the WUI at 50%+ replacement, or for any roof-covering change that does affect the roof structure (material change, pitch change), a permit is required.
Adopted code
2024 editions of the International Building Code (IBC) and International Residential Code (IRC), with local amendments, effective July 10, 2025 — superseding the prior 2021 editions (effective September 1, 2021).
Drip edge
Required — Austin's own local amendment ordinance (City Code § 25-12-243 "Local Amendments to the International Residential Code," Ordinance No. 20250410-040, the executed/signed ordinance read in full, all 10 pages, effective July 10, 2025) does NOT amend R905.2.8.5 -- that section never appears in the ordinance's deletion table or its addition/substitution text (only R905.7.4 and R905.8.5, wood shingle/shake material standards, are added in the R900 range). The governing text is therefore the unamended IRC, which reads identically in the 2021 and 2024 editions: "A drip edge shall be provided at eaves and rake edges of shingle roofs. Adjacent segments of drip edge shall be overlapped not less than 2 inches (51 mm). Drip edges shall extend not less than 1/4 inch (6.4 mm) below the roof sheathing and extend up back onto the roof deck not less than 2 inches (51 mm). Drip edges shall be mechanically fastened to the roof deck at not more than 12 inches (305 mm) o.c. with fasteners as specified in Section R905.2.5. Underlayment shall be installed over the drip edge along eaves and under the drip edge along rake edges." Independently confirmed against up.codes' Austin-specific 2024 IRC viewer (up.codes/viewer/austin/irc-2024/chapter/9/roof-assemblies), which shows identical text and no local-amendment marker on this section. About drip edge
Impact-resistant roofing
Not required — Austin's own local amendment ordinance (City Code § 25-12-243 "Local Amendments to the International Residential Code," within Ordinance No. 20250410-040, the executed/signed ordinance, read in full, all 10 pages, effective July 10, 2025) does not amend Section R902 (Fire Classification) or add any new roof-covering impact-resistance provision. The ordinance's deletion table (Section 25-12-241(B)) and its substitution/addition text (Section 25-12-243) touch only two items in the R900 range -- R905.7.4 and R905.8.5, both wood shingle/shake material standards -- and neither addresses impact resistance. The governing text for roof-covering classification is therefore the unamended 2024 IRC Section R902, which is titled "Fire Classification" and addresses only Class A, B, and C fire-test ratings (ASTM E108/UL 790) for roof assemblies, plus UL 7103/UL 2703 fire-classification requirements for building-integrated and rooftop-mounted photovoltaic systems. No UL 2218, Class 4, or hail-impact-resistance provision appears anywhere in Chapter 9 (Roof Assemblies, Sections R901-R909). Independently confirmed against up.codes' Austin-specific 2024 IRC viewer, whose amendment markers for Chapter 9 flag only R905.7.4 and R905.8.5 as locally edited, matching the ordinance exactly, and whose full chapter text contains zero occurrences of "2218," "impact," or "hail."
Repair permit threshold
Distinct from the Wildland-Urban-Interface 50%-replacement trigger described under Austin's permit process (which governs roof-COVERING replacement under R105.2 items 12-13), Austin's R105.2 "Work Exempt from Permit" (Building list) also carries an unconditional, citywide scope exemption specific to roof DECKING repair, with no WUI carve-out attached to it: "19. Roof decking that does not exceed 128 square feet." (R105.2 items 14, 15, and 18 apply the same 128-square-foot threshold to foundation, floor-decking, and siding repairs respectively, but item 19 is the one specific to roof decking.) Read directly from the signed, executed ordinance (§ 25-12-243, Ordinance No. 20250410-040), page 4 of 10.
Wind design criteria
Austin's own § 25-12-243 (Ordinance No. 20250410-040, the signed, executed ordinance, effective July 10, 2025) fills in TABLE R301.2 CLIMATIC AND GEOGRAPHIC DESIGN CRITERIA as follows: Ground Snow Load 5; Wind Design -- Speed 105 mph, Topographic effects NO, Special Wind Region NO, Windborne Debris zone NO; Seismic Design Category A; Subject to Damage From -- Weathering "Negligible", Frost Line Depth 12 in (305 mm), Termite YES; Ice Barrier Underlayment Required NO; Flood Hazards "Construction Commenced After 9/2/1981"; Air Freezing Index 30; Mean Annual Temp 68.1 (deg F). Read directly from the executed ordinance PDF, page 7 of 10.
Roof layer limit / recover
Austin's own § 25-12-243 (Ordinance No. 20250410-040, executed ordinance read in full, all 10 pages) does not amend Section R908 (Reroofing) at all -- the only R900-range additions in the ordinance are R905.7.4/R905.8.5 (wood shingle/shake material standards), unrelated to reroofing scope. Note the edition change: the 2024 IRC (which Austin adopted) restructured Chapter 9's reroofing sections relative to the 2021 IRC -- the "roof recover not allowed" conditions that sat at R908.3.1.1 in the 2021 IRC now sit at R908.4 in the 2024 IRC, and a new R908.3 "Roof Replacement" section was added ahead of it. Confirmed against up.codes' Austin-specific 2024 IRC viewer, which shows no local-amendment marker on either section: "R908.3 Roof Replacement. Roof replacement shall include the removal of existing layers of roof coverings down to the roof deck." (with exceptions permitting an existing adhered ice-barrier membrane or self-adhered underlayment to remain under stated conditions) and "R908.4 Roof Recover. The installation of a new roof covering over an existing roof covering shall be permitted where any of the following conditions occur... Exceptions: A roof recover shall not be permitted where any of the following conditions occur: [1] 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 the additional roofing. [2] Where the existing roof covering is slate, clay, cement or asbestos-cement tile. [3] Where the existing roof has two or more applications of any type of roof covering." These three disqualifying conditions are unchanged in substance from the 2021 IRC's R908.3.1.1 -- only the section number moved, from R908.3.1.1 to R908.4, and Austin's own ordinance does not touch either the old or new numbering. Re-grounded on the City's own codified instrument: Land Development Code § 25-12-241 adopts the 2024 International Residential Code subject to the deletions it lists and the amendments in § 25-12-243, and Article 11 of Chapter 25-12, read in full as codified through Ordinance No. 20260122-059, carries no provision at Section R908 at all. Its only R900-range provisions are R902.2, R905.7.4 and R905.8.5, all wood shingle and shake material standards. The up.codes viewer is cited above as corroboration only; the claim rests on the City's own code.
Deck & sheathing requirements
Austin's own § 25-12-243 (Ordinance No. 20250410-040, executed ordinance read in full) does not amend R905.2.1. The governing text is therefore the unamended 2024 IRC: "R905.2.1 Sheathing Requirements. Asphalt shingles shall be fastened to wood structural panels or solid lumber sheathing." Confirmed against up.codes' Austin-specific 2024 IRC viewer, which shows no local-amendment marker on this section. Note that this wording differs from the 2021 IRC's R905.2.1 ("Asphalt shingles shall be fastened to solidly sheathed decks") -- the ICC changed this section's wording between the 2021 and 2024 editions. Because Austin adopted the 2024 IRC (effective July 10, 2025), the "wood structural panels or solid lumber sheathing" language governs in Austin, not the older "solidly sheathed decks" phrasing carried by jurisdictions still on the 2021 IRC. Re-grounded on the City's own codified instrument: Land Development Code § 25-12-241 adopts the 2024 International Residential Code subject to the deletions it lists and the amendments in § 25-12-243, and Article 11 of Chapter 25-12, read in full as codified through Ordinance No. 20260122-059, neither deletes nor amends Section R905.2.1. Its only R900-range provisions are R902.2, R905.7.4 and R905.8.5, all wood shingle and shake material standards. The up.codes viewer is cited above as corroboration only; the claim rests on the City's own code.
Sales & use tax
8.25% combined (6.25% state + 1.00% City of Austin + 1.00% Austin MTA (Capital Metro transit authority) special-purpose-district tax), the Texas local-rate cap -- confirmed by direct extraction of the Comptroller's own published rate table (city-rates.xlsx: CityTax 0.01, SPD "Austin MTA" tax 0.01, Total 0.0825, listed for Austin under both Travis and Williamson counties). 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 the City of Austin, Texas. The Development Services Department issues residential roofing permits through the "Austin Build + Connect" (AB+C) portal and administers city contractor registration. Most like-for-like asphalt-shingle reroofs are permit-exempt citywide, but the exemption does not apply inside the Wildland-Urban Interface (WUI) area when 50% or more of the roofing is being replaced.
