Snow Retention Systems fixed with S-5!® – Clamps

According to the state building regulations and the traffic safety obligation of the house owner, snow guard systems are required for roofs on traffic areas and over entrances. Only professional snow guard systems protects pedestrians and objects from falling snow and ice loads.
The following snow guard systems distributed by us are available in various designs and are based on the high holding strength of the S-5!® Clamps. This allows flexible use, even in combination, on all common standing seam roofs.

When snow avalanches off of a rooftop, it can damage anything in its path! This sudden release of snow can be dramatic—dumping tons of snow all at once. Falling snow forms a temperature-sensitive bond to the surface of a metal roof. As that roof is warmed, whether from the sun or from building heat loss, the bond with the snow is broken and a thin film of melt water serves to lubricate the roof. This can have dramatic results as a several-ton blanket of snow suddenly slides off the roof and avalanches down upon anything in its path: gutters, vehicles, landscape, even people. Once piled up below, that same snow bank can go on to cause additional troubles, like direct damage to the building walls, or even indirect damage caused by funneling melt water into, rather than away from, the wall. This is what makes snow retention devices desirable: they hold the snow back and allow it to leave the roof slowly, either in small amounts of snow or as melt water, avoiding the dual calamity of the avalanche.

General Notes for Planning Snow Retention with S-5!

Please follow legal and official requirements for snow retention! Depending on the roof pitch, height above sea level or snowiness, suitable snow guard systems are prescribed and must be calculated and designed professionally. With the snow guard system, the push effect of the snow lying on the roof is to be prevented by one or more rows of snow guards covering the entire area. The decision on the dimension and design of a snow guard system depends on the use and location of the building, and responsible therefor is always the owner of the building. In case of doubt, a structural engineer should be consulted to determine the loads and the dimensioning of the snow guard system.

Assumption is that the determination has been made that the roof to which the snow retention and the S-5! clamps will be attached is structurally adequate. Any loads imposed on the snow retention and S-5! clamps will be transferred to the roof panels. Panel seams must have sufficient flexural strength to carry these loads. Roof panels must also be adequately attached to the building structure, and the structure must be sufficient to carry these loads. The makers and distributor of the RoofTech and S-5! products make no representations with respect to these variables.

It is the responsibility of the userand/or installerto verify this information, or seek assistance from a qualified design or structural professional, if necessary. The user and/or installer of these parts is responsible for all necessary engineering and design to ensure the snow retention and S-5! clamps have been properly spaced and configured. Due to the many variables involved with specific products, climates, snow fall and melt phenomena, and job particulars, the manufacturer and supplier cannot and does not express any opinions as to the suitability of any RoofTech- and S-5!- assembly for any specific application and assumes no liability with respect thereto.

The user and/or installer bears also the responsibility not only for the professional installation, but also for the roof on which he is mounted. The user and/or installer must always clarify in advance the application possibilities and application of our products in connection with the other used materials and products at the single project. The snow guard systems are not suitable as fall protection.

The responsibility for the assembly and the applications is in principle not accepted from RoofTech GmbH und S-5!® – Metal Roof Innovations Ltd..
