Practical next steps

Simple things homeowners in ZIP 63084 can do with this information.

Check your flood zone. Look up your address on FEMA's Flood Map Service Center (msc.fema.gov). Standard home policies don't cover flood damage, and flood insurance usually has a 30-day waiting period, so it's worth sorting out before storm season.
Prepare for freezing weather. Burst pipes are a common winter claim. Insulating exposed pipes, keeping heat on while away and knowing where your main water shut-off is all help.
Know that earthquake damage is separate. Standard homeowners policies exclude earthquakes. If shaking is a concern where you live, ask about a separate earthquake policy or endorsement and its deductible.
Look at your roof. Hail and wind claims often come down to the roof. Impact-resistant (Class 4) shingles can earn discounts in some states, and knowing your roof's age helps when you compare policies.

Historical averages, not a quote. Homeowners figures are inflation-adjusted averages from the U.S. Treasury Federal Insurance Office "Supporting Underlying Metrics" (2018–2022, published January 2025). They cover HO-3/HO-5 policies from participating private insurers and exclude state residual-market plans (such as FAIR plans and Citizens), surplus-lines and flood coverage. Treasury notes that individual ZIP codes can contain data anomalies. Your price depends on your home, coverage and insurer.
