Practical next steps

Simple things homeowners in ZIP 63134 can do with this information.

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.
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.
Compare at renewal. Premiums vary widely by ZIP code, home and insurer. Use these averages as a reference point, not a price, and compare a few quotes at renewal.
Keep records. A roof certificate, receipts for upgrades and photos of your home's condition can help when you shop for coverage or file a claim.

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.
