How much hail does Washington County actually get?
Six recorded events in eleven years. The NOAA Storm Events Database, filtered to Washington County, Texas, from 2016 through September 2026, lists these hail reports:
- 14 May 2016 — Brenham Municipal Airport, 0.75 in
- 26 May 2016 — Brenham, 1.00 in
- 25 April 2023 — Brenham, 1.00 in
- 10 June 2023 — Washington, 1.00 in
- 5 May 2025 — Burton, 1.50 in, the county's largest on record
- 10 May 2026 — Brenham, 1.00 in
Six events, none above 1.50 inches, across the whole county. For comparison, a single spring in the Dallas–Fort Worth area routinely produces more reports than that, at larger stone sizes.
Does that mean hail damage here is rare?
It means the damage threshold matters more here than the frequency does. A 1.00 inch stone bruises an aged asphalt covering and dents soft metal. It leaves a two-year-old architectural shingle largely intact. So the same storm produces a claim on one street and nothing on the next, depending on how old the roofs are.
Washington County's housing stock skews older than the master-planned suburbs south of it. Brenham recorded 7,254 housing units at the 2020 census, with 56.8% of occupied units owner-occupied. Older coverings on a long replacement cycle are exactly the population that a one-inch stone damages, which turns the question into a full re-roof decision.
What about wind, then?
Wind is the county's real roof hazard. The same record lists 17 thunderstorm wind events over the period, against six hail events. The strongest measured gusts were 65 mph, near Washington on 27 May 2020 and near Wesley on 16 May 2024. One tornado appears on the record, an EF0 near William Penn Road on 26 May 2016 that downed numerous trees and caused $10,000 in reported property damage.
Wind at 50 to 65 mph does not usually remove shingles outright. It breaks the seal strip, and the tab stays in place looking undamaged until the next storm takes it. That failure mode is invisible from the ground and is the reason a post-storm inspection pays for itself in this county.
Should a Brenham homeowner pay for impact-resistant shingle?
The hail case for it is weaker here than the marketing suggests; the insurance case is the stronger one. Impact-resistant asphalt runs $5.40 to $8.64 per square foot installed, against $5.00 to $9.50 for standard architectural. The premium is modest, and so is the hail exposure it protects against.
Two questions settle it:
- What discount does the carrier apply? Several Texas insurers credit a Class 4 rated covering. That discount, compounded over twenty years, often outweighs the upgrade cost on its own.
- How long will you own the house? The upgrade pays back over the covering's life, not over five years.
Ask the carrier for the number before paying for the upgrade on hail grounds alone.
What to do with a storm-chaser at the door
A county-wide event brings crews from out of state within days. The record above is the tool for that conversation. A knock claiming last week's storm destroyed your roof is checkable: the NWS logged the event, the date and the stone size, or it did not.
Ask for the date of the event being referenced, then check it. After that, get a dated, photographed hail assessment from someone who will still be answering a phone in Washington County in two years.
