What kind of fence holds up best in high wind?

How wind loads a fence

A solid 6-foot privacy fence acts like a sail. Every square foot of board pushes against the posts, and the posts lever against the soil at the base. Hurricane Beryl gave the Conroe airport weather station a 69 mph gust and Huntsville a 59 mph gust, both preliminary peaks from the National Weather Service. Gusts like that find any post that was set short or sits in loose, wet sand.

Our ground adds to the problem. Most Conroe-area lots have sandy topsoil over clay that drains slowly. After days of rain the sand loosens and grips the post less. That is why no wood-fence post of ours goes in shallower than 24 inches, each one gets an 80-pound bag of concrete, and holes get deeper or wider where the sand is loose or the ground stays wet.

Fence styles ranked for a windy lot

1. Ornamental aluminum or steel. Almost no wind load. A limb strike bends one panel, which is replaced on its own.
2. Chain link without slats. Wind passes through. Add slats and it behaves more like a solid fence.
3. Split rail and ranch wire. Good for marking acreage lines north of Willis or around Huntsville, with nothing to catch the wind.
4. Shadowbox and lattice-top wood or vinyl. The gaps relieve some pressure while keeping most of the privacy. See semi-privacy fences.
5. Solid privacy (board-on-board, solid vinyl, composite). The most load. These work fine when the posts are built for it.

Lake lots and wooded lots

On the east shore of Lake Conroe, lots in Seven Coves, Lake Conroe Hills, and Point Aquarius catch wind that has crossed open water with nothing to slow it. Open aluminum keeps the view and sheds that wind. Where owners want privacy between houses, we keep solid sections short and use stronger posts at the ends.

On wooded lots, the bigger threat is usually what falls on the fence, not wind pushing it over. No fence stops a falling pine. What helps is a build that fails one section at a time and costs little to fix, plus trimming dead limbs over the line before storm season. Our hurricane season checklist covers that.

For storms that do bring a fence down, our repair team can rebuild sections, and the guide to setting posts in Conroe soil explains how we build for the ground under your fence.
