![]() The distance between the brackets depends on the snow load in the region and the slope of the roof, but usually does not exceed 35 inches. One snow guard consists of two or three pipes with a diameter of up to 1″ and several brackets. Tubular snow guards are the most popular and effective type of snow retention system. Some types of snow guards can only be secured to a solid crate, that is why it is better to plan their installation in advance – at least at the stage of when the rafter system is put up. Therefore, when creating a snow guard layout, it is imperative to take into account the crate spacing as well. If the installation of snow retention systems is carried out in two or more rows, the distance between them must also be marked on the layout. This will indicate the location of each snow guard, the distance between them and the eaves overhang, as well the spacing between other elements of the roof. This applies to metal tiles, but also to corrugated profile, classic standing seam roofing panels and even premium copper tiles.īefore installing the snow retention system, you need to make a snow guard layout, i.e., mark snow retention placement and snow guards pattern on the roof drawing. Secondly, due to the smooth surface and high thermal conductivity, the snow and ice mass slides off any metal roof pitch much more rapidly than from rough textured roof areas. Firstly, because this type of roof is very popular in general. Most often, snow retention system is mounted on metal roofing. Usually they are mounted with a spacing of 6 feet from each other. Installing snow guards on the roof in several rows prevents this. If the mass of snow is very large, then during the descent, the layer can gain enormous mass and it will literally rip off the snow guard. The use of several rows of snow guards is required on a long slope or in regions with a heavy snow load.In areas where snow can damage trees, bushes, and supports for plants. Above satellite dishes, antennas and other rooftop equipment.Therefore, the sliding layer of snow can scratch the glass of the roof window if there is no obstacle on its way. This allows the glass for a longer time – there is a lot of dust, ice crystals and other abrasive particles in the lower layer of packed snow. Above the dormer windows so that snow does not sweep them.Installing a snow guard reduces the size of the snow heaps and reduces the risk of leakage. In these areas accumulated snow inevitably sweeps in the wind near any protruded elements on the roof. Over ventilation pipes, deflectors, chimneys to avoid damage.In addition, in order to preserve the entire roof and extend the service life of the roof itself, use of a snow guard system is required: on slopes that are above paths, sidewalks, roads and other places where people can walk, pass or park cars.over wires (electric, television, internet cable).the place above the entrance to the garage.Since it is not always possible to install snow guards along the entire length of the eaves, we give a list of the most dangerous areas where their installation is required: Thanks to this, roof snow and ice gradually descend from the slopes without posing any threat. They either keep snow in place or cut the sliding frozen snow mass into safe small pieces. Installation of an effective snow retention system on the entire roof is designed to prevent this damage. It is easy to imagine the consequences if a car, tree, person, air conditioner or satellite dish are on the way. Add to this the strength and speed that the snow and ice mass gains as it slides down the roof surface. The mass jumping off the metal roof looks like a layer of snow or a block of ice and often weighs hundreds of pounds. This usually occurs when a critical mass of snow and ice load is reached or during thaws, when the snow melts, forming a thin layer of water between the roofing and the snow cover. In the long term, frozen snow falls off the metal roofing. The exception is well-ventilated cold roofs, when the air temperature in the under-roof space is practically the same as outside of the building. Even if the roof is well insulated, heat still goes through the entire roof area, which accelerates the melting of snow and turns it into ice. Every year we see this process in nature and on the roads, and the same happens on the roof. But after a few days it becomes denser, and as soon as the temperature goes over zero, crust appears and the snow mass begins to freeze, eventually turning into a piece of ice. ![]()
