Williamson County Hail Damage FAQ

How many hail events has Williamson County, TX experienced?+

Williamson County, TX has recorded 9005 hail events within a 30-mile radius of the county center since 2015, based on NOAA NEXRAD radar data. With over 9005 events in a decade, Williamson County is considered a high-risk hail area.

What is the largest hail size recorded in Williamson County?+

The largest hail event recorded near Williamson County reached 4 inches. The average hail size across all events is 1.17 inches. Hail of 1 inch or larger can bruise or crack asphalt shingles, and at 2 inches or larger a professional roof inspection is the normal next step after a storm. A recorded size is exposure, not a damage finding. Only a licensed roof inspection can determine whether a specific roof was damaged; coverage depends on the policy and carrier.

When is hail season in Texas?+

Hail season in Texas typically runs March through June. During these months, atmospheric conditions create powerful thunderstorms capable of producing large hail. Williamson County residents should inspect their roofs after any storm and consider a professional inspection each spring.

Does insurance cover hail damage in Williamson County?+

Many standard homeowner's policies in Texas include hail under a "wind and hail" peril, but coverage and deductibles differ from one policy to the next. Claim deadlines and coverage rules vary by carrier and policy — confirm yours with your insurer or your state's insurance department. Document what you observe promptly. Even when nothing is obvious from the ground, a licensed roofer can check for impacts during an inspection — and that inspection, not a hail record, is what shows whether a roof was damaged.

How much does hail damage roof repair cost in Williamson County?+

Hail damage repair costs in Williamson County typically range from $8,000–$25,000+ for full roof replacement. The final cost depends on roof size, pitch, material type, and the extent of damage a licensed inspection finds. Whether a confirmed repair is covered, and what deductible applies, depends on your policy and carrier. Getting more than one contractor estimate before deciding whether to file is a reasonable step.

What is a HailScore and how is it calculated?+

A HailScore is a 0–100 risk index that measures historical hail activity near a specific property. The score is calculated from five factors derived from NOAA NEXRAD radar data: storm frequency, recency, hail size, cumulative damage, and proximity. A score of 0–25 is Low, 26–50 is Moderate, 51–75 is High, and 76–100 is Very High — the same sacred bands used on the live report.
