RoofTech Double-Tube Snow Retention

Some projects require a system providing higher protection against sliding snow, for example in areas with heavy snowfall. Roofs with solar panels also need a higher level of protection to stop snow below the last panels from sliding off. The RoofTech Double-Tube holder, material stainless steel, will be fixed on two S-5! Mini-Clamps and common 32/2mm-tubes will be sliding into the tube holder. The advantages are:

  • Material: 3mm Stainless Steel – very strong and suitable for all metals.
  • Easy fixed on two S-5! Mini-clamps with the M8-screws on top.
  • The lower pipe lies optimal direct on the seam.
  • And the top pipe is 16 – 20cm high above the seam.

RoofTech Double-Tube snow retention: easy to install and high holding strength.

The stainless steel RoofTech Double-Tube holder can be fixed on all S-5! Mini-clamps (also B-Mini for copper roofs !).

Optional we offer ice-stopper, which will be fixed between the lower pipe and the roof. To prevent the ice from sliding beneath the snow guard tube we recommend to install ice stoppers.

General Notes for Planning Snow Retention with S-5!

A professional snow guard is used for traffic safety and protects pedestrians and objects from falling snow and iceloads. The dimensioning and design of a snow guard system depends on the building use and location as well as the roof shape and pitch. The responsibility for this always remains with the builder or building owner. RoofTech GmbH and S-5!® – Metal Roof Innovations Ltd. generally recommend that the snow guard system is planned and dimensioned by a qualified professional.

Double tube snow guard rows should only be used in conjunction with snow guard rows above them because of the leverage effect

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 user and/or installer to 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 lowest snow guard row should generally be installed about 20 to 25 cm from the edge of the eaves. If additional rows of snow guards are provided, the roof surface should be divided into sections of approximately equal size in order to achieve an even load and the best possible effectiveness.

The material properties of the respective metals, the combination with each other and the installation instructions and regulations of all manufacturers involved (including those of the metal roof) must be observed.

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.
