All snow guard devices rely upon the compressive strength of a bank of snow to resist its downward migration. products, you will need to perform additional steps to waterproof these roof penetrations, and you will have to know something about sealant chemistry, part design, sealant selection/sourcing, etc.). stream Attachment Solutions. This results with the greatest compressive strength of the snow bank at its base (adjacent to the roof surface) and at its downslope (eave) end. ISBN-13: 978-1405161039, Built-Up Roof Systems, Manual, C.W. When possible, always attempt to divide the roof areas into equal sections, with equal distance between rows, without exceeding the manufacturer maximum placement guidelines. For this reason, the snow banks downslope extremity is the best place to interface with snow guards., Additionally, Webber notes, Slope is a critical component in the engineering/design of snow retention because steep slopes combined with long panel lengths are two of the factors that help determine if multiple rows of snow retention are needed.. Since they represent a load chain to transfer the sliding forces of snow into the building structure, each link in the chain must be proven to be able to withstand the forces to which it will be exposed.
