Are Metal Roof Snow Guards Necessary?

A snow guard is a device that helps prevent snow and ice from drifting off your metal roof. Without it, your roof can become susceptible to roof avalanches, which can occur due to the sudden release of ice and snow. Besides preventing snow and ice from falling, snow guards can also help keep the lower portion of your roof free of debris. 

If you live in an area prone to heavy snowfalls, we recommend installing snow guards on your metal roof. As the snow accumulates, it can cause ice dams to form and become heavier, which could cause your metal roof to cave in.

A well-maintained metal roof can last for decades more compared to shingles, so investing in snow guards is something that we recommend.

These snow guards are made to keep the objects below the metal roof intact. You need snow guards if you have ever experienced snow or ice falling off your roof. 

How Do Snow Guards Work? 

A snowstorm can create a snowpack composed of snow accumulated on a person’s roof. Although the snow can get kept on the roof for a certain amount of time, the snowpack will loosen as the temperature rises. It can cause the entire sheet of ice or snow to fall suddenly. 

Placing snow guards on sloped roofs can prevent the snow and ice from sliding off. As the weight of the ice and snow melts, it evenly distributes the weight on the roof, which helps prevent damage. It is significant for residential and public buildings. Metal roofs are prone to getting slippery due to their smoothness, making it easy for snow and ice to slide off. It is why snow guards must be installed on these types of roofs

How To Install Snow Guards 

Proper snow guards on your metal roof can help prevent a dangerous avalanche. Without them, the snow and ice can easily slide off your roof and cause structural damage. One of the essential factors you should consider is the overall spacing of the roof. 

Various types of snow guards can get made to fit different sizes and shapes. These can be made with single or multiple components, and these can be separated using a continuous cross-member. A pad-style snow guard uses a combination of devices against the snowpack to reduce the movement of snow and prevent it from migrating. 

A continuous snow guard is made up of two components. These include a seam clamp or bracket attached to the roof and cross-members used to anchor the brackets. These components prevent snow and ice from falling off. 

The snow guards should be placed on the lowest half of the roof, and they should be in rows or single lines. If you plan on using a rail-type system, you should install snow guards about a foot from the eaves. It is where the snow will pile up once the sun has melted it. 

These snow guards should be spaced across the entire roof, starting at around 6 inches above the edge of your roof. It would be best if you then went up about eight feet. Repeat the pattern you used for the bottom edge. 

One of the most important things to remember when installing snow guards on your roof is to pay attention to the instructions provided by the manufacturer. Since these are designed to last long, you should not glue them on; instead, mechanically attach them.
