Austin Hail Season, Read From the Permit Record

The citywide curve

2024 is the heaviest year in the record with 905 permits; 2022 the lightest with 463. That is a swing of 95% between two years in the same city. Roofs do not age that unevenly.

The finding: your neighbourhood has its own storm year

Cross the permits against the city’s own neighbourhood boundaries and something clear comes out: only 12 of the 91 mapped neighbourhoods peak in the same year as the city does. The other 79 peak somewhere else entirely.

That is what a hail band looks like in data. Hail falls in a strip a few miles wide, not across a metropolitan area, so one set of streets gets destroyed while the next neighbourhood over gets nothing. Every citywide hail statistic averages those bands away.

The lag between the storm and the paperwork

Permits are not filed on the day of the storm. Hail falls, adjusters come out over the following weeks, scopes get agreed, and the permit is pulled two to six months later. So a spike in the record marks the season the claims cleared rather than the day the sky opened — and the practical consequence is that the cheap moment to book work is before the wave, not after it.

What this means for a homeowner

• Hail damage on asphalt is bruising, not holes. Nothing leaks that week; the roof fails two or three years later once the exposed mat has broken down under Texas sun.
• That is why insurers set a filing window, and why a roof that looks fine from the driveway may not be.
• Photograph your roof now, undamaged, from the ground on all four sides. After a storm it is the cheapest evidence you will ever have.
• A contractor who existed before the storm is a different proposition from one that did not, and the state register shows which is which to the day.

How this was put together, and what it cannot tell you

Two public files, joined locally. The City of Austin publishes every building permit it issues, with an address, coordinates, a date, a work description typed by whoever filed it, and a declared value. The Texas Comptroller publishes every business holding an active sales tax permit, with the date it first reported sales in the state. Neither office joins them to anything; that is the work.

Four limits worth stating plainly, because most sites quoting permit data do not:

• The record starts in 2006. Anything older is not in it, so nothing here describes how Austin roofs behaved before then.
• Small repairs never appear. A permit is required for replacement and structural work, not for patching. The counts are therefore a floor, not a total — and for work like tarping or inspection, which needs no permit at all, there is essentially nothing to count.
• The work description is free text. Somebody typed it. Searching for a category means searching for several spellings of it and accepting that a permit reading only “new roof” lands in no category at all.
• A declared value is not an invoice. It is written before the old roof comes off, which is exactly when nobody yet knows what the decking underneath looks like.

Where a sample is too small to average honestly, this site says so rather than publishing a number with a confident face on it. Every figure here can be reproduced from the same two files by anybody who wants to check.
