S-5! SnoFence

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.

The stainless steel SnoRod is more durable than aluminum and suggested for projects where greater durability is needed or when the stainless finish is desired for aesthetic reasons. We do not recommend using aluminum SnoRod except for light-duty applications or clamp spacing ≤ 16” on center.

S-5!'s SnoFence is somewhat stronger than SnoRail. Use our metal roof snow fence for increased durability or when the aesthetic look of two rails is desired.
