What are Snow Guards?
Snow guards are essential roofing accessories designed to prevent large accumulations of snow and ice from sliding off your metal roof in dangerous, hazardous sheets or chunks. These protective devices help control the release of snow and ice, allowing it to melt and fall off in smaller, safer portions. By installing snow guards, you can mitigate the risks of property damage, personal injury, or even loss of life caused by avalanching snow and ice.
Importance of Snow Guards on Metal Roofs
Metal roofs are particularly susceptible to snow and ice buildup due to their smooth, slippery surfaces. Without proper protection, the accumulated snow and ice can quickly become a hazard, posing threats to people, vehicles, and structures below. Installing snow guards is crucial for metal roofs to prevent these dangers and ensure the safety of your property and surroundings.

- Consider hiring a professional if you have any doubts or concerns about your ability to complete the installation safely.
Step-by-Step Installation Process
Determining Snow Guard Placement
The placement of snow guards is crucial for their effectiveness. Generally, snow guards should be installed along the edges, valleys, and potential sliding paths of the roof. The spacing between snow guards will depend on the roof pitch, snow load, and manufacturer’s recommendations.
A typical guideline is to install snow guards every 2 to 4 feet along the eaves and valleys, and every 6 to 8 feet across the field of the roof.
Marking the Locations
Once you’ve determined the appropriate placement, use a chalk line or string to mark the locations where the snow guards will be installed. This will help ensure a straight and consistent pattern across the roof.
Securing the Snow Guards
Follow the manufacturer’s instructions carefully to secure the snow guards to the metal roof. Depending on the type of snow guard, you may need to drill holes, apply sealant, or use specific fasteners.
For surface-mounted snow guards, you’ll typically need to apply a compatible sealant or adhesive to the base of the snow guard before securing it to the roof with appropriate fasteners.
For pipe-style or bar-style snow guards, you’ll likely need to drill holes in the metal roof and secure the snow guards using specialized clamps or brackets.
Remember to follow proper safety protocols, such as using fall protection equipment and working with a partner or professional if necessary.
Types of Snow Guards for Metal Roofs
There are several types of snow guards available for metal roofs, each with its own advantages and installation methods. Here are some common options:
Surface-Mounted Snow Guards
Surface-mounted snow guards are designed to be adhered directly to the surface of the metal roof. These guards are typically made of plastic, rubber, or metal and feature a flat base with protruding ridges or teeth to help grip the snow and ice. They are relatively easy to install and can be a cost-effective solution for residential or light commercial applications.
Pipe-Style Snow Guards
Pipe-style snow guards, also known as rail-style or fence-style guards, consist of a series of vertical pipes or rails secured to the metal roof. These guards create a fence-like barrier to hold back the snow and ice, allowing it to melt and fall off gradually. They are often used in commercial or industrial settings with heavy snow loads.
Bar-Style Snow Guards
Bar-style snow guards feature horizontal bars or rods that are mounted to the metal roof using brackets or clamps. These guards are designed to create a sturdy barrier against sliding snow and ice, making them suitable for steep or high-risk roofs. Bar-style guards are commonly used in commercial and industrial applications but can also be adapted for residential use.
When selecting the appropriate type of snow guard for your metal roof, consider factors such as the roof pitch, snow load, budget, and overall aesthetic appeal.
Maintenance and Care
Regular Inspections
To ensure the longevity and effectiveness of your snow guards, it’s essential to conduct regular inspections. Check for any signs of damage, loosening, or deterioration, and address any issues promptly. It’s also a good idea to inspect the snow guards after significant snowfall or ice buildup to ensure they are functioning correctly.
Cleaning and Preserving Snow Guards
Depending on the type of snow guards you’ve installed, you may need to clean them periodically to remove dirt, debris, or salt buildup. Follow the manufacturer’s recommendations for cleaning and preserving the snow guards to maintain their performance and appearance.
For metal snow guards, you may need to apply a protective coating or sealant to prevent corrosion or rust. For plastic or rubber guards, you may need to use a mild detergent and avoid harsh chemicals that could cause deterioration.
