- Strong winds and storms are one of the leading causes of fence damage, and the threat is growing as weather patterns intensify.
- Solid panel fences are far more vulnerable to wind damage than slatted or open-design fences that allow air to pass through.
- Deep, concrete-set posts are the single most important factor in keeping a fence standing during a storm.
- Regular inspection and maintenance significantly reduce the risk of storm damage to existing fences.
- Home insurance typically does not cover storm damage to fences, making prevention even more important.
Strong winds and storms pose a serious threat to fencing, capable of causing significant damage or even complete destruction in a matter of hours. How well your fence holds up against extreme weather depends on a combination of factors: the structural design of the fence, the quality of materials used, how securely it was installed, and how well it has been maintained over time.
As climate change continues to influence weather patterns, storms are becoming more frequent and winds more intense across many parts of Oregon and the Pacific Northwest. The risk to your fence is increasing, and it is worth taking proactive steps to protect it. This is especially important because most standard home insurance policies do not cover storm damage to fences and gates, meaning any repair or replacement costs will come directly out of your pocket.
Steps to Protect Your Fence from Wind and Storm Damage
Choose a Wind-Resistant Fence Design
If you are installing a new fence, the design you choose will have a major impact on how well it copes with high winds. Solid panel fences act as a solid barrier against the wind, creating significant resistance that increases the risk of panels being blown out or posts being uprooted.
A far better approach in exposed or windy locations is to choose a fence design with gaps between the panels, such as slatted, trellis, or hit-and-miss fencing. These designs allow wind to pass through rather than pushing against a solid surface, dramatically reducing the load on posts and fixings.
OnPoint Fencing and Decking offers purpose-built wind-resistant fence installation for homeowners in exposed locations across Oregon.
Use Strong, Deep-Set Fence Posts
The posts are the foundation of any fence, and their quality and depth are the single most critical factor in determining how well the fence withstands a storm. Key guidelines include:
- Posts should be set at least 60 centimetres (2 feet) into the ground as a minimum.
- In particularly windy areas or for taller fences, posts should be set to a depth of at least 90 centimetres (3 feet).
- Always set posts in concrete rather than compacted soil alone. Concrete provides a far more secure and stable fixing and significantly extends the life of the post.
- Concrete posts are preferable to timber posts in exposed settings, as timber posts set in soil can rot over time, weakening the overall structure.
Add Angled Bracing
For additional structural support, install diagonal braces on the side of the fence posts opposite to the prevailing wind direction. Braces should be set at approximately 45 degrees and fixed into the ground using metal spikes. This adds significant resistance to lateral pressure during high winds.
Install Gravel Boards at the Base
Gravel boards fitted at the base of the fence panels prevent direct contact between the timber and the soil. This is important not just for storm resistance but for the long-term health of the fence, as soil contact traps moisture and accelerates rot, which weakens the structure over time.
Create a Natural Windbreak
Planting a hedge along the fence line is a highly effective way to reduce the wind load reaching the fence itself. A dense hedge absorbs and slows the wind before it hits the fence, significantly reducing the pressure on panels and posts during a storm. This approach also adds privacy and natural beauty to your property boundary.
Trim Back Nearby Trees and Shrubs
Overhanging branches and dense shrubs close to a fence line become a hazard in high winds. Falling branches or debris carried by the wind can cause significant damage to panels, posts, and fittings. Carry out regular trimming of any vegetation near the fence line, particularly before storm season.
Secure or Remove Loose Objects Before a Storm
Before a forecast storm, remove or securely anchor any loose objects near the fence, including garden furniture, planters, bins, and decorative items. These can become projectiles in high winds and cause substantial impact damage to fence panels and posts.
Inspect and Maintain Your Fence Regularly
A fence that is already weakened by rot, rust, or loose fixings is far more likely to suffer serious damage in a storm. Regular inspection and maintenance are therefore essential as a storm prevention strategy. During your checks, pay particular attention to:
- Screws, nails, and other fixings, ensuring they are tight and free of rust.
- Panels, checking for any that are loose or showing signs of deterioration.
- Timber surfaces, which should be treated with stain or sealant regularly to prevent moisture penetration and rot.
- Post bases, looking for signs of movement, soil erosion, or rot.

Professional Fence Installation and Repair for Storm Resistance
The most effective protection against storm damage begins with a fence that has been properly designed, built from high-quality materials, and installed correctly from the outset. A well-built fence is simply far more resistant to wind and storm damage than one that has been put together quickly or with substandard materials.

Frequently Asked Questions
What type of fence is most resistant to wind damage?
Fences with gaps between the panels, such as slatted, trellis, hit-and-miss, or chain link designs, are significantly more wind-resistant than solid panel fences. Open designs allow wind to pass through rather than creating resistance, reducing the pressure on posts and fixings during a storm.
How deep should fence posts be set to withstand storms?
As a minimum, fence posts should be set to a depth of 60 centimetres (2 feet). In particularly exposed or windy locations, or for taller fences, a depth of 90 centimetres (3 feet) is recommended. Posts should always be set in concrete rather than soil alone for the most secure and durable fixing.
Does home insurance cover storm damage to fences?
In most cases, standard home insurance policies do not cover storm damage to fences and garden structures. It is worth reviewing your policy carefully and speaking with your insurer to understand exactly what is and is not covered. This makes preventative maintenance and quality installation even more important.
How can I tell if my fence is at risk of storm damage?
Warning signs include leaning or wobbly posts, loose or rattling panels, rust on metal fixings, soft or discoloured timber indicating rot, and any panels that have already shifted or partially detached. If you notice any of these issues, arrange for repairs before the next period of severe weather rather than waiting until damage occurs.
