Home Insurance in Houston, TX

Houston is a flooding market before it is anything else

Houston is a flooding market before it is anything else. The city is flat, drains slowly, and is threaded by bayous — Buffalo, Brays, White Oak — that carry rainfall through the middle of residential neighbourhoods rather than around them. The critical thing for homeowners is that none of that is covered by a homeowners policy: rising water requires a separate NFIP or private flood policy, whatever the premium on the main one says.

The mapped flood zone is a poor guide to who actually needs it

The mapped flood zone is a poor guide to who actually needs it. When Hurricane Harvey stalled over the region in August 2017 it flooded a large number of homes that had never been in a FEMA special flood hazard area, including neighbourhoods affected by controlled releases from the Addicks and Barker reservoirs. Meyerland has flooded in multiple separate storms. Being outside a mapped zone in Houston lowers the price of flood coverage; it does not remove the reason to buy it.

Wind is the second question, and it depends on which side of the count

Wind is the second question, and it depends on which side of the county you are on. The part of Harris County east of Highway 146 sits in Texas Windstorm Insurance Association territory, where standard policies frequently exclude wind and hail and that coverage has to be bought separately. Elsewhere in the city, wind is usually included but often under a percentage-based named-storm deductible — worth pricing in dollars before comparing premiums.

Local weather risk

Houston sits on the Gulf coastal plain, where hurricane season runs June through November and slow-moving tropical systems can drop rainfall faster than the bayou network drains it. Outside of tropical season, stalled summer thunderstorms and spring squall lines produce flash flooding, damaging straight-line wind, and occasional tornadoes. Most common claim drivers: bayou and street flooding from stalled rainfall events, hurricane and tropical-storm wind, with named-storm deductibles, storm surge in the southeast of the county and toward galveston bay, tornadoes spawned by tropical systems and squall lines, hard freezes severe enough to burst plumbing, as in february 2021.
