Did the roof slope change? Was the roof material changed from asphalt shingle to metal? A metal roof will be a much slicker surface compared to asphalt shingle so snow and ice will slide off that was not happening before. Also, re-roof projects that did not originally have a system in place may now need one. Architects and contractors are incorporating snow retention systems in the original design of new construction projects but there is still a great amount of buildings that do not have snow retention. A properly designed and installed system will retain the snow on the roof and prevent damage to gutters, signage, lighting, landscaping, canopies, awning, and vehicles and most importantly of all: people. The key purpose of a snow retention system is to hold and retain snow/ice on the roof and allow a controlled evacuation of the snow, which will help protect your assets and decrease your liability. So how do you choose the right snow guard system for your project? And why are these options so important? Let's focus on some of the key points to navigate through all of your choices. The products offered range in various sizes, shapes, attachment methods, materials, designs and color options. Fast forward to today and there are 20-plus major manufacturers/suppliers. Speak to a solutionist today to find out if snow guards are right for you.Twenty five-plus years ago, you could have counted the number of major snow guard manufacturers/suppliers on one hand. 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.
