What East Texas Storms Do to Waterfront Construction
Straight-line wind, hail, and ice — the three things that take out East Texas docks and walls, and how to design against each.

We don't get hurricanes in Henderson County, but we get every other kind of weather event. The February 2021 freeze and the May 2024 derecho both broke docks that 'storm-rated' marketing copy said were safe.
Straight-line wind (the real risk)
Severe thunderstorm wind is what actually takes down most East Texas docks. Wind events from the May–July storm season routinely produce 60–80 mph gusts; the May 2024 derecho across North/East Texas pushed sustained winds higher than that across a wide swath. Dock roofs are the weak point: a 12×24 ft covered dock develops uplift on the order of 4,000–6,000 lbs in a 70 mph gust.
The fix is engineering, not bigger lumber. Hurricane-strap tie-downs from rafter to top plate and top plate to piling, plus simpson-style ties at every connection, get the load path continuous. The cost premium is small. We spec this as default on any new covered dock now — see the storm-resilient waterfront outcome for the full design checklist.
Ice and freeze (the periodic risk)
East Texas freezes are rare, but when they happen they break things designed for southern-mild climate. Freeze damage in waterfront work usually shows up in three places: split poly water lines on docks, cracked drum-style float chambers, and seawall cap concrete that wasn't poured with enough air-entrainment.
On new construction we spec freeze-rated drum floats, pex-style water lines if there's plumbing involved, and concrete air-entrainment per the most-recent Texas Department of Insurance technical bulletin for the region. None of these add meaningful cost upfront; all of them save a winter repair bill.
Hail (mostly a roof issue)
Severe hail is the second most common East Texas insurance claim type. Dock metal roofing in 26-gauge or heavier with quality kynar coating holds up well in 1.5–2 inch hail. Lighter gauges dent and look bad even when they don't leak; standing-seam aluminum holds up better than corrugated steel in repeated events.
If your dock cover has been hit twice and the insurer is reluctant on the third claim, the right move is usually an upgrade to heavier metal and an insurance-adjusted roofing inspection report. We can scope and supply the documentation for the adjuster.
Storm-rating a dock is mostly continuous-load-path engineering, not over-spend on lumber. Building new or rebuilding after an event? Call us — we'll spec it to a sane storm threshold for the region and document everything for your carrier.
