Most Houston homeowners think about hurricane prep the same way they think about changing smoke detector batteries — they know they should, they mean to, and then June 1st arrives and nothing's been done. I've watched this cycle play out for two decades. The week before a named storm makes landfall, the phone lines at every roofing and window company in Harris County are completely useless. Contractors are booked. Lead times on impact-rated glass stretch past 8 weeks. Permit offices in the City of Houston and unincorporated Harris County are backed up. None of that is a system failure — it's just what happens when a million people try to solve the same problem on the same Tuesday.
The argument I want to make here is simple: the exterior upgrades that protect your home from a Category 2 or a fast-moving tropical storm are not emergency measures. They're permanent improvements. The homeowners who treat them that way — and do the work before the season opens — end up with a better-protected house and a meaningfully higher property value. The ones who scramble in late August get neither.
Here's what to actually prioritize before June.
Your Garage Door Is the Largest Structural Vulnerability on Your House
This is not an exaggeration. A standard residential garage door is the single largest opening in your home's exterior envelope, typically 8–16 feet wide. In a sustained 100 mph wind event, an unbraced door can fail inward, and once that happens, internal pressure builds fast enough to blow off a roof section. This is a physics problem, not a freak accident — it's well-documented in the post-Harvey damage surveys across Katy and Pearland neighborhoods where flooding wasn't even the primary issue.
The fix is not complicated, but it has to be done right. A wind-rated garage door — rated to meet Texas Department of Insurance guidelines and Houston's local amendments to the International Residential Code — runs roughly $1,800–$3,200 installed for a standard double-car configuration, depending on material and insulation value. A retrofit bracing kit for an existing door costs less but only helps up to a point; if your door is older than 15 years or wasn't manufactured to a wind-load rating, bracing is a band-aid. Replace it.
One thing we catch on-site that homeowners almost never notice: the framing around the garage opening itself. On homes built before 2000 — especially the brick-veneer ranch builds scattered across Sugar Land and Pearland — the rough opening framing is often undersized for the hardware requirements of a modern wind-rated door. A proper installation means verifying header depth and sometimes sistering the jack studs. It adds a few hundred dollars and a few hours. Skip it and the door warranty is meaningless.
Impact Windows and Doors: The Trade-Off Nobody Talks About Honestly
Impact-rated windows and exterior doors are the most effective single upgrade for storm protection. That's not a sales pitch — it's what the insurance actuaries believe, which is why most carriers in the Houston area now offer meaningful discounts (sometimes 15–25% on wind/hail coverage) for homes with verified impact glazing. Over a 10-year period, those discounts can offset a substantial portion of the installation cost.
The honest trade-off: impact windows cost significantly more upfront than standard replacements, and not every window in your house needs to be replaced at the same time to get meaningful protection. A full-house replacement on a 2,000-square-foot home typically runs $18,000–$38,000 depending on window count, frame material, and glazing specification. That's a real number. For homeowners who aren't ready for that investment, prioritizing the windward-facing elevations and any large glazed openings (picture windows, sliding glass doors) gets you most of the protection for roughly half the spend.
What matters on the specification side:
- Look for products rated to ASTM E1886/E1996, which is the large-missile impact standard — not just "impact-resistant"
- Verify the product is listed on the Texas Department of Insurance's approved product list
- Confirm your installer is pulling a City of Houston or county permit; unpermitted window work creates title problems when you sell
- Ask about low-E glass coatings — they add minimal cost and meaningfully reduce cooling loads during Houston summers, where a west-facing room can hit a heat index of 108°F with full afternoon sun
The permit piece matters more than people realize. Houston's building department has been stricter since 2020 about retroactive inspection of unpermitted window work, particularly in flood-zone-adjacent areas near Brays Bayou and Greens Bayou.
Roofing and Soffit: Where Storms Actually Get In
A lot of storm damage that looks catastrophic from the street started with a 3-foot soffit failure or a flashing gap around a roof penetration. Wind doesn't need a large opening — it needs a starting point. Once it finds one, negative pressure does the rest.
If your roof is over 15 years old and hasn't been inspected since Harvey hit in 2017, schedule one now. A proper inspection isn't a salesperson walking your yard with a clipboard — it's someone on the roof checking:
- Flashing integrity at all penetrations (vents, chimneys, HVAC curbs)
- Soffit and fascia attachment, particularly at corners and eave returns
- Ridge cap condition and any lifted or missing shingles from the spring hail season
- Attic ventilation balance, which affects both heat load and moisture management year-round
If you need a full replacement, a 30-year architectural shingle with a Class 4 impact rating runs about $9,000–$16,000 on a typical Houston single-story, depending on pitch and complexity. Metal roofing costs more — $18,000–$30,000 in the same footprint — but the longevity and wind resistance numbers are genuinely better. The downside of metal is cost and, in some HOA-governed neighborhoods in Katy and the Woodlands area, deed restriction issues. Know your HOA rules before you fall in love with a standing-seam profile.
The exterior of a Houston home takes more abuse per square foot than almost anywhere else in the country — Gulf moisture, 100°F summers, and a hurricane season that runs through November. Treating these upgrades as one-time, value-building investments rather than emergency expenses is just the more rational way to think about it. The homes we've worked on that came through Beryl in 2024 with minimal damage weren't lucky. They were prepared.
