Imagine it’s a cold winter morning in Wisconsin. The snow has been steadily falling for hours, and your metal roof is starting to accumulate a thick layer. Suddenly, a large chunk of snow and ice breaks away, sliding off the roof with tremendous force. It crashes down onto your driveway, crushing a shrub, damaging your car, or — worse yet — hitting someone walking below. This scenario is all too common in regions like Northeastern Wisconsin, where snowfall is frequent, and heavy snow sliding off the roof is a real concern.
This is especially the case with metal roofs. While metal roofs are known for their durability and efficiency, the weight and movement of snow can pose a significant risk. One solution to this issue is to install snow guards.
In this blog post, we’ll get into what snow guards are, why they’re crucial for metal roofs, and how to choose the best snow guards for your home.
What Are Snow Guards?
Snow guards, sometimes referred to as snow fences or snow retention systems, are devices installed on metal roofs to prevent large amounts of snow or ice from sliding off suddenly. When snow accumulates on a metal roof, it has the potential to slide off quickly, often with great force. This can be dangerous for anyone standing or walking below and may result in costly damage to property, landscaping, or gutters.
Snow guards work by slowing the movement of snow, allowing it to melt gradually or slide off in smaller, more controlled amounts rather than in one large sheet. In essence, they act as a “catcher” for the snow, providing a safer environment for both the people living in the house and the surroundings.
Best Types of Snow Guards for Metal Roofs
When it comes to snow guards, there is no one-size-fits-all solution. Different types of snow guards are available for metal roofs. Each of these snow guards meets the needs of different roof profiles and snow conditions. Below are the most common types of snow guards.
Self-Adhesive Snow Guards
As the name suggests, self-adhesive snow guards have a sticky backing that allows them to be applied directly to the surface of the roof. These are usually made of rubber or other soft materials, and they can be an excellent solution for low-pitched roofs or areas with lighter snow loads. However, they may not be as effective in regions with heavy snowfalls or high winds, as they are less durable over time.
Several types of snow guards fall under the self-adhesive category. For example:
- Pad Style Snow Guard: A small, flat plastic pad that is installed on the edge of the roof (mostly in batches).
- Rib Style Snow Guard: Similar shape to a pad style snow guard but attached to the ribs or seams of a metal roof.
Clamp On Snow Guards
If you have a standing seam metal roof, clamp-on snow guards are popular because they are versatile and easy to install. They attach directly to the rib or seam of the metal roof without the need for drilling, which makes them a great choice for homeowners who want a non-invasive solution. These guards are available in various materials, including aluminum, stainless steel, and plastic, and can be adjusted to fit different roof profiles.
Soldered or Welded Snow Guards
For those who are looking for a permanent and highly secure solution, soldered or welded snow guards are the best option. These guards are directly integrated into the roof panels during the manufacturing process, making them a seamless part of the roofing system. They are highly durable and can withstand even the harshest snow and weather conditions. This type of snow guard is often seen in commercial roofing projects but is also suitable for residential metal roofs.
Snow Fences
Snow fences, also called snow retention systems, are larger and more robust than typical snow guards. They are typically installed along the edge of the roof and consist of a series of vertical bars or mesh. These fences are ideal for areas that receive frequent and heavy snowfall, as they can hold a large volume of snow without allowing it to slide off all at once. Snow fences are more common in industrial and commercial settings but can also be used for residential properties.
Why Should You Install Snow Guards on Metal Roofs?
Snow and ice buildup on roofs may seem like a minor concern at first, but the dangers are real. Northeastern Wisconsin averages about 40 to 50 inches of snow, even higher in the central area, so you need to make sure this snow does not damage your metal roofing system.
Here’s why installing snow guards on your metal roof is a smart choice:
Prevents Injury and Property Damage:
The main reason why you need to install snow guards is to prevent the risk of injury to people and property damage. As we said above, the heavier the snow gets, the higher the chance it will slide off the roof panels. And when it gets heavy, it can do serious damage.
When snow or ice suddenly slides off a metal roof, it can create hazards for pedestrians, vehicles, or animals below. Snow guards provide a physical barrier that prevents this from happening, ensuring that snow falls in a controlled manner.
Protects Your Roof and Gutters:
Metal roofs are strong, but the sudden weight and pressure of a large snow slide can cause damage to both the roof and gutters. Snow guards help preserve the integrity of your roof by preventing excessive buildup and ensuring that snow melts and slides off gradually, reducing strain on the materials.
Maintains Aesthetic Appeal:
Without snow guards, heavy snow accumulation can lead to uneven melting, which might result in icicles hanging from the edges of your roof. These icicles can cause water damage if they thaw and drip into your home. Snow guards prevent this issue, preserving both the function and appearance of your roof.
Compliance with Local Building Codes:
Depending on where you live, local building codes may require snow guards, especially in areas that experience heavy snowfall. Installing snow guards can help you stay compliant with these regulations. Even if they are not required as per the code, it is still a good idea to install them.
