Snow guards are devices that are installed on metal roofs to manage the snow and ice from sliding off in dangerous chunks. By keeping snow in place until it melts gradually or can be removed safely, they help ensure that the roof performs its job without creating hazardous conditions.

     They come in many shapes and sizes. Generally, snow guards are installed in rows or clusters along the roof’s slope, typically near the eaves, ridge, or other vulnerable areas.

     When snow accumulates on the roof, it forms a barrier that prevents it from sliding off suddenly. Snow guards do not necessarily “hold” the snow in place in the sense of an immovable block; they slow the rate at which snow and ice can slide off.

     By breaking up the span of the roof into smaller sections, snow guards help to prevent a massive, sudden avalanche of snow. This ensures that the snow will melt or slide off in small, manageable amounts over time, rather than all at once. 

      Slowing down the snow’s movement, snow guards can help alleviate the form of ice dams. Ice dams occur when warm air from the attic melts snow on the roof, causing it to refreeze at the eaves, where the roof is cooler. Over time, this ice can build up and block proper drainage, leading to leaks and water damage inside the building.

Conclusion

     Snow guards are an important feature for metal roofs in areas that experience heavy snowfall and cold weather. Preventing dangerous snow and ice avalanches, they help keep your home, property, and loved ones safe. Snow guards are a smart investment that can protect your metal roof and give you peace of mind during the winter months.
