The best fence for Colorado wind (and what blows down)

Every winter we get the same call: "My fence blew over again." Here on the Front Range, wind isn't a once-in-a-while thing — it's the main reason fences fail. The good news is that a fence built the right way will stand for decades. Here's what blows down, what doesn't, and why.

Our wind is no joke

If you live in Castle Rock, Highlands Ranch, Parker, or anywhere along the foothills, you already know the wind. A lot of it is Chinook wind — warm, dry gusts that pour down off the mountains in winter. Those storms regularly push gusts past 60 miles an hour, and they hit fences harder than almost anything else in your yard.

Most fences that come down don't fail because the wood is bad. They fail because of three things: shallow posts, weak panel attachment, and a solid wall that gives the wind nothing to pass through.

Why a cheap privacy fence blows over

A solid privacy fence is basically a giant sail. The taller and more solid it is, the more wind it catches. When a 60-mph gust slams into a six-foot wall of wood, all of that force has to go somewhere — and it goes straight into the posts and the nails.

Here's where the cheap builds give out:

• Posts set too shallow. A post sunk only a foot or two deep snaps right at ground level in a big gust. We see it every spring.
• Panels nailed straight to the rails. A couple of nails per board can't hold against that kind of pressure. The boards work loose and whole sections peel off.
• No gaps. A perfectly solid fence has nowhere for the wind to go, so it takes the full hit. A little airflow makes a huge difference.

Cut corners on any one of these and the wind will find it.

The styles that actually hold up

The trick with wind is to let some of it through while still getting the privacy you want. A few designs do this well:

• Shadowbox (good-neighbor) fence. Boards alternate front and back with a small gap between them. From the yard it still reads as private, but wind slips through the gaps instead of slamming the whole wall. It also looks the same on both sides, which most HOAs love.
• Cedar or steel-frame privacy with a small gap. Leaving a little space between boards bleeds off wind pressure without giving up much privacy at all.
• Ranch rail or split-rail on acreage. Out toward Larkspur, Elizabeth, and Parker's bigger lots, an open ranch-style fence barely catches wind at all — perfect when you're marking property lines, not blocking views.

A solid, board-to-board privacy fence can absolutely work here too — it just has to be built on the right bones. Which brings us to the part that matters most.

The best materials for wind

For the look most homeowners want, a cedar fence on a steel frame is hard to beat on the Front Range. You get the warm, natural cedar face, but the posts and rails are steel — and steel doesn't rot or warp at the ground line, which is exactly where wood fences usually start to fail. A steel backbone shrugs off wind that would rack and loosen an all-wood fence over time.

Whatever the face material, the posts are the whole game. A beautiful fence on weak posts is a fence you'll be standing back up in March.

Setting posts deep — past our frost line and our clay

This is the step that separates a fence that lasts from one that leans. The Front Range gives posts two problems at once: wind pushing from the side, and clay soil that swells when wet, shrinks when dry, and freezes every winter. That freeze-thaw movement is called frost heave, and it slowly shoves shallow posts right up out of the ground.

Here's how we set posts so neither one wins:

• Dig 30 to 36 inches deep. That puts the bottom of the post below our frost line, where the ground movement can't grab it. A standard two-foot hole isn't enough here.
• Add a gravel base. A few inches of gravel at the bottom lets water drain away from the post instead of pooling and freezing against it.
• Set in concrete. Concrete around a deep post gives the wind a big, heavy anchor to fight against — and it loses.

Do those three things in that order and you've solved both the wind and the heave in one pour.

The bottom line

The best fence for Colorado wind isn't really about one magic material — it's about a style that breathes a little and posts set deep enough to anchor it.
