Snow guard

A snow guard system keeps the sliding snow in the eaves or roofs with longer fixed on the roof surface. Is particularly in snowy winters is a risk that large amounts of snow slide off the roof and so unpredictable cause property damage and personal injury. To prevent such dangerous roof avalanches, snow, different security systems can be mounted on roofs.

Species

  • A snow guard ensures that the snow is jammed in the eaves of the roof. When installing, make sure that both the material and the fixing to the sub-structure can withstand the enormous scale and selective pressure loads due to snow. Snow guards are the variant most commonly used for snow fuse.
  • In addition to snow guard grilles provide snow guard bar / round woods or snow guards just for snowy areas a more stable great safety as snow guards are powder skirt bar / round woods or snow guards attached to the eaves of the roof to catch the sliding snow.
  • A snow stop tile used for the secure attachment of snow guard snow guard grilles or bars on roof tiles. It is usually adapted to the shape and color of the roofing tiles employed.
  • Snow gaiter hooks are spread all over the roof surface and prevent the snow from slipping off. Due to the snow trap hook the snow is kept on the roof at high masses of snow, so that less snow on the snow skirt system, such as the snow guards, acting. Snow hooks can be used alone or in combination with snow guard systems in the eaves. The hooks can be hung in almost all types of roof tiles and roof tiles and, when combined with snow guard systems optimum protection especially for roofs with a high inclination angle.
  • Another way roof avalanches on the roof to avoid so-called roof heaters. They ensure that the snow melts, thus preventing any high snow loads or roof avalanches. However, the use of roof heating takes place closer to very specific applications.

Legal regulation

In general, a home owner in Germany is not obligated to equip its roof with a snow guard system. However, to meet the general duty to maintain safety, he must take all reasonable precautions to avoid damage due to roof avalanches. Should any damage from snow slide, the homeowner is liable to 50%. Roofs with a slope angle of about 50 degrees have to be secured separately, otherwise the house owner is fully liable for any damages. In addition, the security requirements in the partially divergent state building codes are regulated.

Snow load calculation

In general it can Germany be divided according to the geographic location in several snow load zones. The higher a building is, the higher the allowable snow load is to be set, which is calculated according to ZDVH - control system for load determination of snow loads based on the new DIN EN 1991.
