Practical next steps

Simple things St. Charles homeowners 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.
Ask about wind mitigation credits. Features like hurricane straps, a newer roof and impact-rated windows or shutters can lower premiums. Ask your insurer which upgrades earn a discount and what paperwork it needs.
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.
