Home / Houston Hurricane Prep
Hurricane season, handled.
Houston has hurricane season every year — the question is how prepared the home you’re buying already is. Window protection, generator basics, insurance riders, evacuation routes, and the specific items to check during the option period. The annual prep list and what it actually costs.
Section 1
What hurricane season actually looks like in Houston
The Atlantic hurricane season runs from June 1 to November 30. The Gulf Coast sees the heaviest activity from mid-August through October. In a typical year, NOAA forecasts 12–19 named storms across the entire Atlantic basin; a small fraction reach the Texas coast in any given season.
Houston sits roughly 50 miles inland from Galveston Bay. That distance matters: storm surge is a coastal phenomenon, while inland Houston’s primary hurricane risk is wind and — the bigger one historically — rainfall flooding. Hurricane Harvey in 2017 dumped over 40 inches of rain across the metro and caused most of its damage that way, not through coastal surge.
So when buyers ask “how worried should I be about hurricanes,” the honest answer is: it’s a real consideration that local agents know how to navigate, and the specific risk depends a lot on where the property sits relative to coastal exposure, flood zones, and recent storm history. None of that is unsolvable — it’s just due diligence we do up front.
Section 2
How hurricane exposure shows up in a Houston home purchase
When you’re buying in Greater Houston, hurricane exposure shows up in three places: the insurance you’ll need to carry, the property’s claim history, and the FEMA flood-zone designation.
Insurance you’ll need
Standard homeowners insurance covers wind in most of Greater Houston. Properties east of Highway 146 in Harris County, plus Galveston and Brazoria coastal counties, need separate windstorm coverage through TWIA. Flood is always separate.
Claim history (CLUE report)
Lenders and insurers pull the CLUE database during underwriting. Prior wind, hail, or flood claims on a property show up here. Sellers must disclose known issues on the TREC Seller’s Disclosure Notice.
FEMA flood zone
The zone designation (X, AE, VE, etc.) determines whether flood insurance is required by your lender, and what it costs. See the Houston flood zone buyer guide for the deep dive.
Section 3
Wind vs. flood vs. windstorm — three different policies
This is the one piece almost every out-of-state buyer gets wrong. In Texas, hurricane coverage isn’t a single policy. It’s split across three different products, and a Greater Houston home may need one, two, or all three.
Standard homeowners (HO-3)
Covers wind, hail, fire, theft, liability. In most of Greater Houston, this is what carries the bulk of hurricane wind coverage. Required by lenders.
TWIA windstorm policy
Texas Windstorm Insurance Association — the state-managed pool for coastal properties. Required for homes in 14 Tier-1 counties and parts of Harris County east of Hwy 146 (Baytown, Pasadena, Seabrook, La Porte, etc.). Standard insurers exclude wind in these zones.
Flood insurance (NFIP or private)
Federal program (or private flood policy) covering rising-water damage. Required by lenders in FEMA A and V zones. Smart to carry in Houston anywhere near a bayou, regardless of zone — Harvey flooded 30,000+ homes outside designated zones.
The gotcha buyers miss
Wind insurance excludes flood. Flood insurance excludes wind. When a hurricane causes both, claims can get adjudicated separately. Carry both, and document storm damage with timestamps the day it happens.
If you’re shopping east of Hwy 146 or along the coast
Get a TWIA quote before you write your offer. Coastal premiums can be a thousand dollars or more above what an inland Houston quote would suggest, and TWIA eligibility requires a Windstorm Certification of Compliance (WPI-8) showing the home was built or retrofitted to code. Older homes without certification can be hard or expensive to insure.
Section 4 · Process
How to read a property’s hurricane history before buying
Check the FEMA flood zone for the exact address.
FEMA’s Map Service Center is free. Zone X (minimal hazard) is what most Houston buyers want to see. AE, AO, or VE means the property is in a Special Flood Hazard Area — flood insurance is required by federally-backed lenders.
Ask the seller about Harvey, Imelda, and Ike.
The TREC Seller’s Disclosure Notice asks about prior flooding. A seller who’s owned through 2017 (Harvey), 2019 (Imelda), 2008 (Ike) and can say “no water in the house” is giving you real signal. Ambiguous answers warrant a deeper look at the claim history.
Pull a CLUE report.
The CLUE report shows insurance claims filed on the property in the last 7 years. Sellers can order their own copy free from LexisNexis. Wind, hail, and water claims show up here even when not flagged on the seller’s disclosure.
Get insurance quotes during the option period.
Two reasons. First, the actual annual premium becomes part of your real monthly cost. Second, if an insurer balks because of a prior claim or roof age, you find out while you can still negotiate or walk — not after closing.
Confirm the roof age and condition with the inspector.
Texas insurers care a lot about roof age. Roofs older than 15–20 years often trigger higher premiums or actual-cash-value claim settlements instead of replacement-cost. A roof certification from a licensed inspector can sometimes unlock a better rate.
Section 5
Pre-storm prep for owners — what actually matters
If you already own a Greater Houston home, here’s the short list I keep on hand for clients in June. None of this is novel — it’s the boring stuff that holds up when a storm forms in the Gulf.
Before June 1
Photograph every room and the exterior with your phone — with timestamps. Confirm wind and flood policies are current. Replace batteries in flashlights. Trim trees with overhanging branches over the roof or driveway.
When a named storm enters the Gulf
Move outdoor furniture, grill propane, planters indoors. Fill prescriptions. Charge devices and external batteries. Check on neighbors, especially older ones living alone. Top off the gas tank early.
If evacuation is called
Follow ReadyHarris and your county emergency office for live guidance. They are the authoritative source, not social media. Bring policy numbers, ID, prescription list, and the photographs from your phone’s cloud backup.
After the storm
Document everything before you start cleanup — photos and video, timestamped. File claims promptly. Mitigate further damage (tarp the roof, board windows) but keep receipts. Beware of unlicensed contractors going door-to-door.
Authoritative live-storm sources
National Hurricane Center (nhc.noaa.gov), National Weather Service Houston/Galveston (weather.gov/hgx), ReadyHarris (readyharris.org), and your county Office of Emergency Management. Not social media, not real estate blogs — including this one.
Section 6
How I work with buyers on hurricane considerations
For out-of-state buyers, this is one of the first conversations I have. Houston’s hurricane exposure isn’t the same in every neighborhood, and the right answer for an Inner-Loop buyer in The Heights is different from the answer for a buyer looking in Clear Lake or Seabrook.
When we’re looking at a specific property, I’ll pull the FEMA zone, check the parcel against Harris County flood-claim records when available, and flag whether the address falls inside TWIA territory. If anything looks unusual — an unusually low elevation, a recent claim, a roof past insurance-friendly age — we’ll get insurance quotes during the option period so you know your real monthly cost before you waive contingencies.
For investors, hurricane exposure is a real underwriting input. A pier-and-beam rental in Galveston needs windstorm coverage and elevated build-out; the same purchase price in Cypress can carry standard insurance and a Zone X flood policy as a hedge. The cap rate looks different once those line items hit the model.
None of this is doom-and-gloom. Hurricane season is part of life on the Gulf Coast. Greater Houston has been doing this for a long time and the playbook is well-established. The job of a Houston REALTOR® is to make sure you know what you’re buying before you close on it.
FAQ
Houston hurricane questions buyers ask
Do I need flood insurance even outside a flood zone?
Federally-backed lenders only require it in FEMA A or V zones. But Harvey flooded an estimated 30,000+ homes that were outside designated zones. Carrying a flood policy in Zone X is relatively inexpensive in Houston ($400–$800/year is common) and worth strong consideration anywhere near a bayou or low-lying area.
Does TWIA cover everyone in Houston?
No. TWIA covers 14 designated Tier-1 coastal counties (Galveston, Brazoria, Aransas, etc.) plus parts of Harris County east of Highway 146. Most of Greater Houston is outside TWIA territory and gets wind coverage through a standard homeowners policy.
How can I tell if a house I’m looking at flooded during Harvey?
Ask the seller directly on the TREC Seller’s Disclosure Notice. Cross-check with a CLUE report (insurance claim history) and a title search for any FEMA grant assistance recorded against the property. For homes that flooded and were remediated, look for visible signs at the inspection — new drywall lines, mismatched flooring, replaced subfloors, fresh paint in lower wall areas.
Will my mortgage company require windstorm insurance?
If the property is in a TWIA-eligible zone (east of Hwy 146 in Harris County, or Tier-1 counties), yes — the lender will require it because standard homeowners policies exclude wind in those areas. In the rest of Greater Houston, wind is covered under your standard HO-3 policy.
Are there neighborhoods I should avoid because of hurricane risk?
There aren’t neighborhoods to avoid — there are properties to look at carefully. Buyers love specific neighborhoods (Bayou-adjacent in the Inner Loop, the historic homes in Galveston) that have meaningful storm exposure. The job isn’t avoidance; it’s knowing what you’re buying, insuring appropriately, and pricing accordingly.
What does a typical hurricane-related claim cost a Houston homeowner?
Wide range. A wind-driven roof claim might run $8,000–$25,000 to repair, mostly covered by HO-3 minus deductible (often a separate, higher hurricane deductible — 1–5% of dwelling coverage). A flood claim depends entirely on water depth and is paid through your separate flood policy, capped by NFIP limits ($250K dwelling, $100K contents) unless you carry private flood with higher limits.
If I move from out of state, when should I start the insurance conversation?
As soon as we’re looking at specific properties, not after we’re under contract. Insurance availability and cost can vary meaningfully between two homes a mile apart. You want this in your underwriting picture early.
Is there anything I should do in the first 30 days of ownership?
Photograph everything inside and out. Save copies of your homeowners, windstorm (if applicable), and flood policy numbers. Sign up for ReadyHarris alerts and your county’s emergency notification system. Identify two evacuation routes from your address. That’s the basic hurricane-readiness baseline for a Greater Houston homeowner.
