Homeowners Insurance & Natural Hazard Costs in Round Rock
Round Rock's real hazard profile is flash flooding and severe thunderstorm/hail risk, not hurricanes -- the city sits within "Flash Flood Alley" and Brushy Creek, which runs through town, has a documented flood history and repeated recent closures. Homeowners insurance here reflects that: a separate wind/hail deductible is standard, and flood coverage is a distinct policy worth taking seriously given Brushy Creek's proximity to many neighborhoods.

The average Texas homeowners insurance premium is cited around $389/month statewide, not including a separate flood policy. One Round Rock-specific example cited a $110/month quote in the 78664 zip code from a single carrier (State Farm) -- worth treating as one data point from a single insurer rather than a representative citywide average, since premiums vary substantially by home age, roof condition, construction, and specific carrier. Get a property-specific quote rather than budgeting off either figure alone.
Hail Risk and the Wind/Hail Deductible
Williamson County experiences multiple severe hail events most years, which carriers price into Round Rock policies -- hail damage repair costs for a 2,000-square-foot home are cited in the roughly $4,850-$7,005 range. Most Williamson County homeowners policies carry a separate wind and hail deductible, typically 1%-2% of dwelling coverage; on a home insured for $383,700 at the higher 2% rate, that works out to a $7,674 out-of-pocket cost before coverage applies on a hail claim -- a real, easy-to-overlook cost next to the headline premium. An impact-resistant Class 3/4 roof is worth asking about specifically, since it can meaningfully reduce the wind/hail portion of a policy.
Flash Flood Risk: Brushy Creek and Flash Flood Alley
Round Rock sits within the broader "Flash Flood Alley" region of Central Texas, and Brushy Creek -- which runs directly through the city -- has a documented flood history on record with the U.S. Geological Survey dating to at least September 1921. The risk is active, not historical only: low-water crossings closed amid flash flood warnings in May 2025 and July 2025, and again amid flooding in April 2026, per City of Round Rock and Community Impact coverage. Standard homeowners insurance does not cover flood damage -- flood insurance is a separate policy, typically through the National Flood Insurance Program (NFIP), which is cited at an average $791/year in Texas for roughly $274,000 of coverage. Given Brushy Creek's proximity to many Round Rock neighborhoods, confirming FEMA flood zone status for a specific property -- and carrying flood coverage even outside a mandatory zone -- is a genuinely important step here, not a formality.
Texas FAIR Plan: The State Insurer of Last Resort
The Texas FAIR Plan Association (TFPA), managed by the Texas Windstorm Insurance Association, is Texas's residual-market insurer for homeowners who have been denied coverage by at least two private insurers. TFPA coverage is generally less comprehensive than standard voluntary-market policies, and its policy count grew meaningfully statewide in 2024 (41,234 new policies, the largest single-year increase on record) as private insurers tightened terms in some higher-risk parts of the state. Most Round Rock homes with reasonable construction and roof condition are expected to qualify for standard private coverage rather than needing TFPA, but it is a real, if narrow, backstop worth knowing about.
Key takeaways
- Texas homeowners insurance averages around $389/month statewide; a single Round Rock-zip-code quote example cited $110/month from one carrier -- get a property-specific quote rather than relying on either figure.
- Williamson County sees multiple severe hail events most years; expect a separate wind/hail deductible (typically 1%-2% of dwelling coverage, e.g., $7,674 on a $383,700 home at 2%) -- an impact-resistant Class 3/4 roof can meaningfully reduce this cost.
- Round Rock sits in "Flash Flood Alley" and Brushy Creek has a documented flood history dating to at least 1921, with recent closures in May 2025, July 2025, and April 2026 -- flood insurance is separate from homeowners insurance (NFIP averages ~$791/year in Texas) and worth carrying even outside a mandatory flood zone.
- The Texas FAIR Plan Association is the state's insurer of last resort for homeowners denied private coverage -- policy counts grew meaningfully in 2024, though most Round Rock homes with reasonable construction are expected to qualify for standard private coverage.
