Short answer
Open fences hold up best: aluminum, chain link, split rail and spaced picket let wind pass through instead of catching it like a sail. If you want privacy, a semi-private style with gaps, such as shadowbox or spaced board, takes less load than a solid 6 ft wall. Whatever the style, deep, well-set posts matter most. In Berks County that means footings sized for a colder freezing index than Montgomery County's, and corner and gate posts set heavier than line posts.
What the 2025 Amity storm showed
On July 1, 2025, the National Weather Service confirmed an EF-0 tornado with peak winds of 70 mph in Amity Township, tracking from Weavertown Lane toward Boyertown Pike. Straight-line winds up to 70 mph also pushed toward Boyertown and the north side of Gilbertsville. Residents told WFMZ a wood shed was "blown apart" and a swimming pool destroyed. Montgomery County has its own history: a deadly tornado hit Limerick Township on July 27, 1994, with the Hamlet development taking the worst of it.
Nobody builds a backyard fence to survive a direct tornado hit. But a lot of fences sit at the edge of a storm like that, in straight-line gusts rather than the funnel, and that's where design and installation decide whether a fence rides it out or ends up in the neighbor's yard.
How fence styles compare in wind
| Style | How it handles wind | What to watch |
|---|---|---|
| Aluminum ornamental | Wind passes through the open pickets; very little load | Gate hinges and latches on long gates |
| Chain link | Open mesh, low load | Adding privacy slats or windscreen turns it into a sail |
| Split rail | Almost no wind load | Rails can be knocked out by falling limbs |
| Spaced picket or shadowbox wood | Gaps let air through; moderate load | Post rot at grade over time |
| Solid 6 ft wood privacy | High load on every panel | Post depth, rot, and long unbraced runs |
| Solid 6 ft vinyl privacy | High load; panels can pop out of rails if posts flex | Post reinforcement at gates and ends |
A solid 6 ft privacy fence is still a reasonable choice on a sheltered lot. The question is how exposed your line is. A fence running across an open field edge in Amity or along a ridge above Boyertown takes a different beating than one tucked between houses in Gilbertsville.
Installation matters more than material
- Post depth and footing. Penn State's Housing Research Center puts Berks County at an Air Freezing Index of 2,000, against 1,500 or less in Montgomery and Chester, and raises its minimum frost-protected footing depth from 12 in to 14 in. Posts that heave a little each winter loosen in their footings, and a loose post is the first to fail in a gust.
- Heavier ends and gates. Corner, end and gate posts carry the most load. We set them deeper and wider than line posts.
- Shorter runs on exposed sides. On an open side we keep the section between corners or braced posts shorter, so one failure doesn't fold a whole run.
- Gates that latch. A gate left unlatched in a storm acts like a lever on its hinge post. A drop rod or second latch on drive gates helps.
Local rules that shape your choice
Two Berks townships near the 2025 storm track have chain link rules worth knowing. Amity Township allows chain link only if it's screened from neighboring properties by a high-intensity buffer planting, and Douglass Township (Berks) allows it only with landscaping that hides it from adjacent properties and the street. Both cap fences at 6 ft. A planted screen can also take some wind off the fence line, though it takes years to fill in. If you're weighing chain link against aluminum in either township, count the cost of the plantings.
After a storm
If a fence goes down, take photos before you clean up, check for downed wires before you touch anything, and don't reset posts until the ground has been marked if any digging is involved. Whether your homeowners policy covers wind damage to a fence depends on your policy, so call your agent. Our repair crew can reset leaning posts and replace broken sections, and we'll tell you honestly if a run is past saving.
At the estimate we'll walk the line with you and point out the exposed stretches before you pick a style.
Common questions
Is vinyl or wood better in high wind?
Both solid styles take about the same load. What decides it is how the posts are set and reinforced. Vinyl panels can pop out of their rails if posts flex too much, and wood posts lose strength as they rot at grade.
Will windscreen on a chain link dog run blow over?
It can. Windscreen and slats turn open mesh into a solid surface. If you add them, the posts need to be set for a solid fence.
Does a taller fence catch more wind?
Yes. A taller fence catches more wind, and more of the load sits farther from the footing. That's one more reason not to push a solid fence past what you need, even where the township allows more.
