Most Houston homeowners replace their windows after a storm. That's backwards. The windows aren't usually what fails first — it's everything holding the envelope together that goes quietly wrong in the months before August 1st, when the Atlantic season hits its statistical stride. I've walked enough storm-damaged homes in Pearland and the Heights after Harvey and Beryl to know that the real casualties are the components nobody inspects: the roofing underlayment that's been baking at 110°F for a decade, the soffit panels rattling loose on a 1980s fascia board that never got a second coat of paint, the garage door that's rated for 90 mph winds on a house sitting in a 130 mph zone.
If you're going to spend money on storm hardening before September, spend it on those three things first. Here's why, and what that actually looks like.
Why Your Roof Deck Matters More Than Your Shingles
Everyone talks about shingles. Shingles are almost irrelevant. What determines whether your roof survives a Category 2 or 3 event is what's underneath them — specifically, whether your deck is properly fastened and whether your underlayment can hold as a secondary water barrier if the shingles peel.
Houston's residential building code (per the 2021 IRC adoption Texas phased in) requires 8d ring-shank nails at 6-inch spacing in field panels for high-wind zones. A lot of homes built before 2010 don't have that. They have smooth-shank nails at wider spacing, and under sustained 100+ mph winds, those panels can rack. We've pulled back roofing on post-Harvey repairs in Sugar Land and found 1/2-inch OSB panels with inadequate fastening that had shifted enough to open up seams — before a single shingle blew off.
The fix isn't necessarily a full re-roof. If your shingles have life left and the deck is sound, a qualified contractor can add an ice-and-water shield underlayment layer — real peel-and-stick, not the 15-lb felt that was standard before 2005 — to give you meaningful secondary protection for around $2,500–$4,500 on a 2,000-square-foot ranch. That buys you a lot of peace of mind relative to the $35,000–$60,000 interior repair bill that follows a roof deck breach.
What Harvey Taught Us About Soffits and Fascia
Soffits are the panels that close off the underside of your eave overhang. On most Houston homes built between 1975 and 2000, they're vinyl or aluminum over a wood sub-fascia that has been wet and dried and wet again through thirty hurricane seasons. What happens in high wind is this: pressure difference between outside and the attic space creates uplift under the soffit panel. If it's loose — and in my experience, most are at least partially loose — it peels away. Once the soffit opens, wind and rain enter the attic directly, and from there it's a short trip to your ceiling and insulation.
This is exactly what we saw play out in neighborhoods near Brays Bayou after Harvey in 2017. Homes that lost soffits before they lost shingles had two to three times the interior water damage of homes that didn't. The mechanism is counterintuitive — you expect damage to come through the roof surface, not through a 12-inch strip of ventilation panel — but the physics are simple.
Reinforcing soffits isn't glamorous work. It involves re-securing panels with longer stainless fasteners, replacing rotted sub-fascia boards, and in some cases switching from vinyl to aluminum panels that actually grip. On a typical two-story in Katy, budget $1,800–$3,200 depending on linear footage and how far gone the underlying wood is. While the crew is up there, have them inspect the fascia board condition and the gutter attachment — gutters add significant pull-load on a fascia board in wind-driven rain, and a rotted board will let them peel right off, taking soffit sections with them.
On-site, here's what this actually looks like: you'll see a remodeler pressing upward on soffit panels every 18 inches or so, feeling for flex. Any panel that moves more than a quarter-inch is effectively loose. On older homes, we'll sometimes find the original fasteners have oxidized into powder — they look like they're holding until you push. Wood sub-fascia that sounds hollow when tapped has delaminated from moisture cycling. None of this is visible from the ground.
The Garage Door Problem Nobody Talks About Enough
The garage door is the largest, most wind-vulnerable panel on most Houston homes. Full stop. A standard 16-by-7-foot double garage door has 112 square feet of surface area catching wind load, and the horizontal rails it rides on were not designed to brace it laterally against a hurricane.
An unbraced single-layer steel door in 100+ mph winds will flex inward, bow, and eventually fail — and when a garage door fails mid-storm, the pressure change inside the structure can contribute to roof uplift from the interior. FEMA documented this failure mode extensively after Andrew in 1992, and Florida mandated hurricane-rated doors after that. Texas has not mandated them statewide, but Harris County's local amendments to the IRC do impose stricter wind-load requirements on new construction and permitted replacements.
Your options, ranked honestly:
- Hurricane-rated replacement door — the right answer for doors over 15 years old. Rated doors use heavier-gauge steel, additional horizontal bracing rails, and stronger end stanchions. Installed cost runs $1,200–$2,800 for a standard double door.
- Vertical bracing kit — a legitimate interim fix for a newer, structurally sound door. Steel or aluminum vertical braces bolt to the door sections and anchor to the floor and header. Materials plus labor run $400–$900, and they work — but they require installation before the storm, not during.
- Retrofit horizontal struts — effective on some door styles, less so on older sectional doors with lightweight panels. Ask your contractor to assess panel gauge before recommending this.
The downside of the bracing kit over a full replacement is honest and worth naming: it adds significant time to storm prep because you have to physically install it each time a storm threatens. If you travel for work during hurricane season, that's a real operational problem. A rated door just works, all the time, without that labor step.
Before the Peak: A Pre-August Checklist
If you're getting this work done before September, sequence it this way:
- Have your roof deck fastening and underlayment assessed first — it affects everything above it
- Inspect and re-secure soffit panels and sub-fascia while roofers are already mobilized
- Evaluate garage door rating and age; budget replacement if it's pre-2005 or unrated
- Check gutter attachment points, especially at corners and downspout drops
- Confirm any exterior repair permits are pulled — Harris County inspections book out 3–4 weeks during summer storm prep season
The work isn't complicated, but the timing is tight. Peak Atlantic hurricane activity runs statistically from mid-August through mid-October. Crews get booked fast once a named storm forms in the Gulf.
