Snow retention systems vs. individual snow guards: which is best for metal roofs?
When it comes to protecting a metal roof from the weight and potential damage caused by snow, two popular options are snow retention systems and individual snow guards. Each option has its own advantages and considerations, so let’s take a closer look at both.
Snow Retention Systems
Snow retention systems are designed to hold snow in place on the roof, preventing it from sliding off in large quantities. These systems typically consist of multiple rows of snow guards or clips that are strategically placed along the roof surface. The goal is to evenly distribute the weight of the snow across the roof, reducing the risk of sudden snow slides or avalanches.
One of the main advantages of snow retention systems is their ability to provide a uniform distribution of snow. By keeping the snow in place, these systems prevent large amounts of snow from sliding off the roof all at once, which can be hazardous for people below and damaging to the roof itself.
Snow retention systems are especially beneficial for roofs with steep slopes or areas where the snow accumulation is significant. By preventing massive snow slides, they help to minimize the risk of roof collapse and damage to property or individuals.
Individual Snow Guards
Individual snow guards, on the other hand, are installed in specific areas of the roof where snow often accumulates or where there may be localized structural weaknesses. These singular snow guards work by creating small barriers that prevent the snow from sliding down in large quantities. They are installed at key points such as the eaves, valleys, or near areas with skylights or heavy roof accessories.
The advantage of individual snow guards is that they can be installed selectively, focusing on areas that are most prone to snow buildup or areas where snow slides pose a particular risk. This targeted approach allows for more cost-effective installation and can be a suitable solution for roofs with less slope or lower snow accumulation.
However, it’s important to note that individual snow guards may not provide the same level of uniform snow distribution as a full snow retention system. In cases of heavy snow accumulation, there is still a possibility of localized snow slides or uneven weight distribution.
Choosing the Best Option
Deciding between a snow retention system and individual snow guards depends on various factors, including the roof slope, snow accumulation patterns, and budget. In general, for roofs with steep slopes and high snow accumulation, a full snow retention system is recommended to ensure proper snow distribution and minimize the risk of damage.
For roofs with lower slopes or areas where snow accumulation is less of a concern, individual snow guards can provide sufficient protection while keeping costs down. These can be strategically placed to address specific areas of concern.
Ultimately, consulting with a professional roofing contractor or snow guard expert is essential for determining the best option for your specific metal roof. They will assess the roof’s characteristics, local climate, and your specific needs to recommend the most effective snow retention solution.
