Snow guards: Are they necessary on a Metal Roof?
A question that we get asked a lot, is if it is really necessary to install snow guards on a metal roof. The short answer is that it depends where you live. Lets unpack some of the information regarding snow guards.
What is the purpose:
The purpose of snow guards is to hold accumulated snow on the roof, until it can slowly melt. Lets say that you live in a area that receives 4-6 inches of snowfall regularly. The snow can build up on your roof throughout the winter until there is 12″ or more accumulated. As the weather begins to warm, this accumulated snow can slide off the roof in large chucks, causing possible damage to gutters and personnel. If snow guards are installed, they prevent the snow from sliding, until it has a chance to melt.
What Damage can be Caused:
Depending on the situation, and the severity of the winter, the lack of snow guards can cause a lot of damage. Sliding snow and Ice can tear gutters off of your home, requiring new gutters to be installed. Chunks of snow can also slide off at the most inopportune times,inuring anyone that happens to be standing in its way. The last thing that you need is to have someone suing you because of being injured by sliding Snow and Ice.
What options of Snow Guards are available:
There are several options of snow guards available depending on the style and look that you prefer. There are plastic snow gems that can be caulked, or screwed to the roofing surface. These are very economical and can be installed with little effort. There are also continuous bar options for both the Ag Panel and Standing Seam Roofing. These bar option are the cadillac of snow guards and are proven to work well in all conditions. If you are looking for a more decorative look, there are many options along that line as well.
Snow guards are something that can be overlooked at times, however, they play a important part in the performance of your roofing. Talk to your installer and be sure that this vital component is not neglected.
