Enhancing safety through permanent monitoring
snowcontrol scales are an effective and cost-saving alternative for monitoring roof loads - particularly on flat roofs - caused by snow and ice. Our patent-proof system represents an optimized model of a snow-scale. Due to its circular shape, just one weighing cell is necessary to calculate weights very precisely. Any other shape would have to use more than one cell, thus increasing risks of device failures and measuring errors. The system's low height guarantees for accurate mapping of roof waste heat. The farther away from the roof's top , the higher the measurement error. Snowdrifts are captured by the scale's open construction. Closed constructions tend to imply the risk of probing errors due to shaded areas.

Based on economic considerations, extreme snowload situations occuring just infrequently are not included in the standards. In parts of the alpine region and the Bavarian Forest the factual snowload during the winter season of 2005/2006 as specified in the standards (and therefore also in DIN 1055-5: 1975-06) exceeded its presumpted load, then beeing established by German building authorities, by far. As a consequence, roofs had to be cleared from snow in order to prevent building collapses. It clearly appeared that often roof snowloads were not payed its due attention.
As opposed to information about avalanche situations, qualified information for house owners and construction experts about current snowloads are supplied neither by building control authorities nor weather services, even if local standards are exceeded in large scale.
