Inside City of Austin limits, you usually do not need a permit to replace an asphalt shingle roof with asphalt shingles. The city’s list of work exempt from a building permit includes shingle-for-shingle replacement, other roof coverings that do not adversely affect the roof structure, and up to 128 square feet of roof decking. The big exception is the Wildland-Urban Interface (WUI): if your property is in the WUI and 50 percent or more of the roof is being replaced, the exemption does not apply. Exempt or not, the city says the work still has to comply with the building code. If you live in a suburb, the rules are different, and some suburbs require a permit for every reroof.

Permit or no permit: a quick check
| Your job | City of Austin permit? |
|---|---|
| Asphalt shingles replacing asphalt shingles, outside the WUI | Exempt |
| Asphalt shingles replacing asphalt shingles, in the WUI, under 50% of the roof | Exempt |
| Any roof covering, in the WUI, 50% or more of the roof | Permit required, and the WUI rules apply |
| Different covering that does not adversely affect the roof structure | Exempt |
| Heavier covering that adds load, such as tile over framing built for shingles | Likely permit required, since it can affect the structure |
| Replacing more than 128 sq ft of decking | Permit required |
| Structural repairs, new rafters or a new roof shape | Not on the exempt list, so plan on a permit |
“Exempt” means no building permit, not no rules. The roof still has to meet the adopted code, and a sloppy tear-off with no inspection is still a sloppy tear-off.
The Wildland-Urban Interface rule
Austin adopted the 2024 International Wildland-Urban Interface Code with local amendments on April 10, 2025. It applies to permit applications submitted on or after July 10, 2025; earlier applications fall under the 2015 WUI code. The WUI covers a large share of the west side, so do not assume you are outside it.
- Zones. Zone A is 0 to 50 feet from wildland. Zone B is 50 to 150 feet. Zone C is more than 150 feet and up to 1.5 miles from 750 acres or more of wildland, or up to half a mile from 40 acres or more.
- Class A roof in every zone. The covering must be Class A fire rated, with gaps fire-stopped or covered with an approved cap sheet.
- Valleys. Metal valley flashing over approved underlayment.
- The 50 percent trigger. Replacing 50 percent or more of the roof requires a full replacement to WUI standards.
- Inspection timing. A fire inspector checks that installed materials match the approved plans.
Look your address up on the city’s Interactive WUI Code Map before you sign a roofing contract. If you are in a zone, ask every bidder to price a Class A system with metal valleys. Most asphalt shingles, including the Class 4 lines we install, carry a Class A fire rating; wood shakes are a different story.
How an Austin roof permit works
When a permit is required, the City of Austin’s process runs through its Austin Build + Connect (AB+C) portal:
- The contractor registers. The general contractor on the permit needs an AB+C account and a city contractor registration. The city does not require a state license to act as a general contractor, and a homeowner can act as one for their own house.
- The permit is applied for and approved, with the scope, materials and, in the WUI, the fire-rated system.
- Activation. Only a registered general contractor, or a homeowner acting as the general contractor, can pay for and activate the permit.
- Posting. The permit is posted at the street-facing entrance.
- Inspection. Schedule the first inspection listed on the permit. A permit expires 180 days after activation if no on-site inspection has been done.
Ask your roofer whose name goes on the permit. If a contractor asks you to pull it as the homeowner, you take on the responsibility for the work. That is a red flag.
Suburbs and unincorporated areas
Every city around Austin writes its own rules, so check where the house actually sits. We have local permit guides for Round Rock, Georgetown, Pflugerville, Leander, Lakeway, Bee Cave, Dripping Springs, Cedar Park, Kyle, Buda and San Marcos. An HOA may also want plans, colors and a contractor name before work starts, even when the city does not.
Checking a roof before you buy or sell
City of Austin permit records can be searched in the AB+C portal. If a seller says the roof was replaced, search the address for a building permit and inspection results. No permit is not proof of a problem, because most shingle reroofs are exempt, but a roof in a WUI zone, a tile roof or a roof with new decking should have one. Ask for the invoice, the product name and the manufacturer warranty registration either way.
A roof done right, permit or not
We pull the permit in our name when a job needs one, price WUI-compliant systems for west-side homes, and tell you plainly when a job is exempt.
