Short answer: For most Austin homes, no. The City of Austin doesn’t require a building permit to replace asphalt shingles with asphalt shingles, or to replace any roof covering without changing the roof structure. The big exception is homes in Austin’s Wildland-Urban Interface (WUI) wildfire area, where replacing 50% or more of the roof covering needs a permit. Historic homes changing materials need a separate approval, and your HOA may need to sign off either way.
Rules change as soon as you cross a city line. Round Rock doesn’t require a permit for a residential re-roof. Georgetown requires one for every re-roof. Austin sits in between, and where your house sits matters more than you’d expect.
Here’s how to work out which rules apply before the first shingle comes off.
Do you need a permit to replace a roof in Austin?
Not for a straight replacement, in most of the city. Austin’s list of work exempt from building permits includes:
- Asphalt shingles replacing asphalt shingles
- Replacing any roof covering that doesn’t adversely affect the roof structure
- Roof decking repair up to 128 square feet, which is about four standard sheets
The exemptions stop applying when:
- Your home is in the WUI area and 50% or more of the roof covering is being replaced. Then you need a permit. More on this below.
- The job changes the structure. Examples include reframing, changing the roof pitch, or moving to a much heavier material like tile that the framing wasn’t built for.
- A lot of decking needs replacing. Anything over 128 square feet isn’t on the exempt list. It’s common to find rotten decking once the old roof is off, so a good roofer will tell you what that means before tear-off.
When in doubt, Austin Development Services answers permit questions at 512-978-4000. These are City of Austin rules. If your home has an Austin mailing address but sits outside city limits, check which rules apply to you.
What is Austin’s wildfire code, and does it apply to you?
If you live near greenbelts, preserves or Hill Country brush, it may. Austin says it was the first major Texas city to adopt the International Wildland-Urban Interface Code. The city adopted it in 2020 and moved to the 2024 edition in 2025.
The code sorts homes into three zones based on distance from wildland:
| Zone | How close to wildland |
|---|---|
| A | 50 feet or closer |
| B | More than 50 feet, up to 150 feet |
| C | More than 150 feet, up to 1.5 miles from a large wildland area (750+ acres), or up to half a mile from a smaller one (40+ acres) |
To check your address, use the city’s Interactive WUI Code Map on Austin Fire’s Wildland-Urban Interface Code page. If you’re in Zone A or B, the city says to confirm by measuring on site to the nearest wildland.
What does the wildfire code mean for a new roof?
Replacing half or more of the roof means bringing all of it up to code. That applies in every zone:
- Replacing 50% or more of the roof covering requires a full replacement that meets the WUI code, and a permit.
- In every zone (A, B and C), the roof must have a Class A fire rating, the highest there is. Gaps have to be fire-stopped or covered.
- Eaves, soffits, vents and gutters have their own ember-resistance rules in every zone, a little looser in Zone C. Your roofer should check these as part of the job.
One line from the city is worth remembering: even if a permit isn’t needed, the work still has to follow WUI code requirements. A roofer who works in West and Southwest Austin should already know this and bring it up without being asked.
Do you need historic approval for a new roof?
Only if you’re changing materials on a protected property. Austin requires a Certificate of Appropriateness for exterior changes to:
- a city historic landmark
- a property pending landmark designation
- a contributing building in a local historic district
Contributing homes in a National Register historic district also go through the city’s historic review.
The city’s list of work needing that approval includes replacing roof materials with a different material. Switching from composition shingles to metal is one example. Smaller projects can be approved by city staff within about five business days. Larger ones go to the Historic Landmark Commission, so allow extra time.
Routine maintenance and in-kind repairs don’t need historic review. Questions go to the Historic Preservation Office at preservation@austintexas.gov.
Does your HOA need to approve a new roof?
In many Austin neighborhoods, yes, even when the city doesn’t. HOA rules often cover shingle color, profile and material. That’s separate from, and often stricter than, anything the city requires.
Texas law does protect one important upgrade. Under Texas Property Code § 202.011, an HOA can’t prohibit shingles designed to be wind and hail resistant, more energy efficient or solar-generating, provided they:
- resemble the shingles already used in the neighborhood
- are more durable and of equal or better quality
- match the surrounding homes
That protection covers shingles. It doesn’t guarantee approval for a switch to metal or tile. (Our metal vs. shingles guide covers that choice.)
The order that saves you time:
- Choose the exact product and color with your roofer.
- Submit it to your HOA and keep the approval in writing.
- Sort out any WUI permit or historic approval at the same time, not one after the other.
What should you ask your roofer?
Ask how they know which rules apply to your address. A roofer who works across Austin should be able to tell you:
- whether your home is in a WUI zone, and which one
- whether the job needs a permit, and who pulls it (it should be them)
- what happens if they find more rotten decking than expected
- whether the materials they’re quoting will pass your HOA
- whether your home is in a historic district
