S-5! DualGard

A snow guard is a device or system that increases friction between roof and snow, retaining a snow pack on a roof, so that it evacuates in a predictable and controlled fashion (evaporation and thaw) rather than by a sudden and dangerous rooftop avalancheWhen 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. This can have dramatic results -damaging gutters, vehicles, and landscape. Once piled up below, that same snowbank can go on to cause additional troubles, like structural or cosmetic damage to the building walls. In any event, the removal of avalanched snow from walkways, entries and parking areas is a constant maintenance nuisance.

Falling snow forms a temperature-sensitive bond to the surface of a metal roof. As that roof is warmed, (through an invisible spectrum of sunlight or from building heat loss), the bond with the snow is broken and a thin film of meltwater lubricates the roof. This causes a sudden release from a rooftop that can dump many tons of snow below the eaves in a matter of seconds, endangering building elements, landscape, vehicles and pedestrians.

SnoClip, X-Clip and DualClip will stop or retard the passage of snow and ice beneath the snow retention cross member. If other flashing elements (e.g., eave guttering accomplishes this purpose) are utilized, then it may not be necessary—so its use is somewhat discretionary depending upon the eave details and project specifics. We recommend it in most cases. In general, one SnoClip per panel on the first row of snow retention will suffice. When seam spacing is >24″, two or more SnoClips per panel are recommended.

Why is it a bad idea to put snow guards over doorways only? Should the snow retention system be customized to the job? Yes—any product should be—including those sold by other companies. Everything has a failure point, which is why products are tested. The idea, then, is not to expose a product to forces which exceed its known point of failure. These forces are predictable and can be calculated accurately for any application. Ask us for a free assessment.
