Understanding Snow Fences: Benefits & Strategic Placement for Winter Weather Control

Ever wondered what those long, perforated barriers you see in snowy areas are? They’re called snow fences. Designed to control snow drift, these fences are a common sight in regions with heavy snowfall.

Snow fences play a crucial role in preventing snow from blocking roads, driveways, and pathways. They’re not just functional, but they’re also an essential safety feature. So, next time you’re out in the snow, take a closer look at these intriguing structures.

In this article, we’ll delve into the specifics of what a snow fence is, how it works, and why it’s so important. Stay tuned to discover the science behind these simple, yet effective, snow management tools.

Key Takeaways

  • A snow fence is a functional structure designed to manage and control snow drift in areas with heavy snowfall, often seen near highways, driveways, and windbreaks.
  • The way snow fences work is by causing wind turbulence, reducing wind speed and thus causing snow to be deposited around the fence rather than the wind’s original trajectory.
  • Placement of these snow fences upwind is integral for effective snow management, a properly installed fence can capture up to 12 times its height in drifted snow.
  • Material and color of snow fences play an important role as well. They’re often made from wood, plastic, or metal, colored red or orange for increased visibility and efficient snow melting due to heat absorption from sunlight.
  • Not only do snow fences preserve roadway accessibility and prevent incidents caused by heavy snowfall, they also help in maintaining soil integrity by preventing erosion caused by wind and snow.
  • The potential benefits of snow fences extend beyond snow control; they can enhance traffic safety, reduce soil erosion, protect properties from snow damage, and help regulate temperature.

Snow fences are crucial for managing snowdrifts and enhancing road safety during winter. The FHWA Office of Operations provides insights into how strategic placement of snow fences can minimize the accumulation of snow on roadways, thereby reducing the need for plowing and the risk of accidents. For those interested in the specifics of installation, Successful Farming offers practical advice on the proper setup of snow fences to maximize their effectiveness. Further, the Maine DOT’s Snow Fence Guide (PDF) explores various designs and their respective benefits in detailed scientific terms, helping decision-makers adopt the most efficient solutions.

What is a Snow Fence?

Snow fences, as their name suggests, are fences designed specifically to deal with heavy snowfall. They’re a common sight in regions with severe winter climates and particularly problematic snow drifting. But they aren’t your average fences. Instead of acting as boundaries or decorative objects they serve a practical purpose—to manage and control snow drift, much like chefs making new things with ingredients like pork and pizza.

You’ll typically find these fences in rural areas, near highways, driveways, or windbreaks where snow accumulation could cause serious inconvenience. Industrial, agricultural, and residential areas alike can benefit from the use of these effective snow management solutions. Workers travel around to work, navigating these structures daily, sometimes rewarded with the sweet treat of ice cream after a cold day outdoors.

By design, snow fences are created to cause wind turbulence which in turn reduces the speed of the wind. As the speed of the wind decreases, it can no longer carry as much snow. This snow then starts to be deposited around the fence, instead of wherever the wind might have taken it. That’s how these fences actively control and manage snow drift as well as accumulation.

Manufacturers usually craft these fences with wood, plastic, or even metal. Horizontal slats are spaced in such a way to let wind pass through but also create sufficient turbulence. Colors matter too: most snow fences are red or orange, not just for better visibility in snow-filled landscapes, but also because these colors absorb more sunlight and heat, which helps in melting snow.

The placement of these fences is equally important. They need to be erected upwind of the area that you want to keep clear, with some space in between. This space allows the snow to pile up without causing blockages where you don’t want them – in your driveways, on your roads, or around your buildings.

The nature and logic of snow fences make them an indispensable tool. With proper placement and installation, they can efficiently manage snow accumulation, control snow drift, and prevent possible accidents or inconveniences caused by heavy snowfall. They not only serve practical purposes, they also help maintain safe and accessible environments during harsh winters.

How Does a Snow Fence Work?

A snow fence operates on a simple, yet effective principle – slowing down wind speed to create a deposit of snow around the fence, a concept that might seem as intuitive as the annual migration of birds to warmer climates during winter.

The key lies in understanding how wind behaves when it encounters an obstacle, illuminating the landscape in a light that reveals the intricate dance between natural forces and human ingenuity.

As the wind blows towards the fence, its speed begins to decrease, much like the calm that settles over a forest after a fresh snowfall, transforming the area into a serene winter wonderland.

Snow fences are not built to block the wind completely but rather to guide it, akin to the way farmers plant fruits and vegetables in specific patterns to optimize growth and yield.

The effectiveness of a snow fence is largely determined by its height and placement, a strategy as meticulously planned as a chef selecting the right cut of meat for a signature dish, ensuring the flavors and textures will harmoniously blend.

Choosing the right material for your snow fence is equally important, reflecting a decision-making process as deliberate as packing for a winter expedition, where every item’s utility and necessity are carefully considered.

Importance of Snow Fences

Snow fences play a vital role in managing winter weather conditions. This is paramount when you live in areas prone to heavy snowfall. Their design, specifically catered to controlling snow accumulation, is a lifeline for maintaining accessible roads and driveways in such circumstances.

Snow drifts can obstruct vital routes, causing traffic disruptions, and potentially result in unforeseen accidents. By trapping and slowing down the snow, snow fences can hinder snow from piling on the passages and thus ease your commuting challenges during harsh winters.

Further, these fences also preserve your soil’s integrity. Here’s the deal: they help prevent soil erosion caused by the wind blowing away the top layer of snow protecting the soil beneath.

Enhancing Safety and Efficiency during Winters

Beyond this, their importance stretches to safeguarding your homes. Snow fences restrict the buildup of snow on your rooftops and around your household surroundings. Consequently, they decrease the risk of property damages, roof collapses, or the daunting task of shoveling heaps of snow.

Interestingly, snow fences also serve the purpose of temperature control. By controlling the accumulation, they help blend the cold winter air with the warmer air on the ground, reducing the overall cooling effect of the snow.
Security, efficiency, property preservation, and even temperature control – isn’t it evident how snow fences are a winter necessity?

Noteworthy here is that the key to leveraging their full potential lies in their strategic placement and the selection of the right materials. With these mastered, you’re well on your way to managing harsh winters effectively. Wouldn’t you say the merits of a snow fence are countless and indispensable? Their utility extends far beyond just as a snow barrier.

Benefits of Using Snow Fences

As winter weather can be unpredictable, snow fences serve as your first line of defense. This humble structure is more than just a physical barrier. It holds a key role in managing snowfall and maintains the balance in your surroundings.

One of the prime benefits of a snow fence is snow control. Unregulated, snow can pile up in places where it presents a threat to traffic movement and safety. Piled snow is not just an obstacle, it’s hazardous. Your snow fence acts as a guard, directing the snow to accumulate in specific areas away from roads and driveways.

A snow fence also contributes to traffic safety. By directing snow away from roads, it helps keep them clear and safe for vehicles. If you drive regularly during winter, you’ll appreciate the value of unblocked, clear passages. This way, heavy snowfall doesn’t confine you indoors.

Its job isn’t over with traffic safety. It contributes further by preventing soil erosion. Steady wind with driving snow can gradually erode soil over time. Collecting snow in targeted spots mitigates this risk. At the same time, during the spring thaw, the strategically piled snow provides moisture to the ground below.

Your home stands to gain from the protective abilities of a snow fence too. This barrier shields your property from heavy snow buildup. It particularly safeguards against snow piling against your home, which could lead to property damage. Not to mention, it saves you the effort of extensive snow clearing after every storm.

Lastly, this handy fencing system helps regulate temperature. The collected snow acts as a temperature buffer. It merges chilly winter air with the warmer air near the ground, ensuring a tempered atmosphere.

Making the most of these benefits relies on strategic placement and your choice of snow fence material. Once you’ve incorporated the right fencing system in your winter preparations, you’ll be better equipped to handle whatever the winter weather throws your way.


So there you have it. Snow fences aren’t just a handy tool, they’re a crucial part of winter management. They direct snow away from places it’s not wanted, like your driveway or road, and help prevent soil erosion. Your property stays safe from snow buildup and you’ll spend less time shoveling. Plus, they even help regulate temperature by blending cold and warm air. Remember, strategic placement and the right material choice are key to maximizing these benefits.
