8/28/2023 0 Comments Snow rails for metal roofsImportant in choosing the right snow guards for standing seam panels is ensuring the quality of the guards, and that the method of attachment does not damage the panels so as to void the metal roof warranty. These work in conjunction with each other to form a snow retention system. There are standing seam snow guards that are a single unit (meaning that no additional parts are needed), and there are standing seam snow guards that require additional clamps in order to be attached. There are a few options for standing seam snow retention, all of which fit into the two major categories of snow retention systems which are discontinuous and continuous systems.ĭiscontinuous Snow Retention for Standing Seam Panelsĭiscontinuous snow retention systems are in short what most would call “snow guards.” These are individual guards that are placed in a staggered pattern along the eave of the metal roof. Standing seam metal roofs are among the most popular for retail, hospitals and clinics, as well as private homes. The two major panel types are standing seam and exposed fastener. Finding the Right Snow Retention Systemįinding the right snow retention system is largely dependent on the type of metal panels being used. To view the original article, click here. This informative article from Levi’s Building Components, the makers of Snow Defender® Snow Guards, will help you understand their necessity and the different types available. Speak to a solutionist today to find out if snow guards are right for you.Snow guards are an important part of your metal roof they protect guttering, landscaping and even people from dangerous snowfall by breaking up the snow. Some of the best products still require a support of many different solutions to achieve the ultimate solution. The Brothers that just do Gutters offer snow guard installations along with a multitude of other services to help control the winter season’s adverse snow conditions. This will ultimately cause problems down the road. Sometimes an insulator can be applied to the materials to prevent this but rainwater will still cause and electrolyte or corrosive bridge to form. The differences in the metallic compounds will cause differences in alkalinity in the materials. Using the same metallic alloy for both the roof and the snow guard is advised to prevent the corrosion challenges that will occur. However, when it comes to metal roofs, they come in various metallic options including aluminum, copper, galvanized and galvalume steel. We use aluminum in gutter installations because it has a low corrosiveness and environmental friendly attributes. When using cedar shakes or stone tiles, aluminum is a favorable material. The lexan guard is attached to a metal roof using a bonding agent designed for the weather elements. Lexan snow guards provide the lowest visibility option as well as providing the most favorable solution for maintaining roof integrity and preventing corrosion. However, there are alternative methods to properly melting the snow and ice.Ĭhoosing the type of snow guard that will be installed depends on the type of roof that is on the residential or business building. We do not recommend using heat tape on many roof surfaces due to roof warranties and fire hazards. In many colder climates where snow guards are used to keep snow on the roof, a heating source will also be applied to the roof to aid in melting the snow. In extreme weather conditions, the snow and ice will not properly melt off the roof, but continue to build up on top of the roof. The snow guard is designed to hold the snow on the roof in these conditions. Even in situations of proper attic insulation, thawing beneath the roof will cause the entire roof surface to become slick enough causing the weight of the ice block to cause it to slide off the roof. The bonded lump of snow will then freeze overnight creating a dangerous block of frozen ice. As the snow accumulates in wet snow conditions, it may bond together. Asphalt roofs will typically provide enough grip to prevent the snow from sliding off the roof. Typically, snow guards are utilized on homes or businesses with extremely steep roofs or roofs constructed of slate, wood or metal. They hold the snow on the roof so it gradually melts off from the radiant sun or other heat source. The function of a snow guard is to prevent snow or ice from cascading off of the roof and onto your landscaping, cars, or people below. What are snow guards? Snow guards come in all shapes, sizes, and styles.
