Snow guards can be found in various shapes and sizes. There many new start-up companies going into the snow guard business every year that are starting off on the wrong foot with their products shaped like the image on the right.
Mid-faced snow guard designs allow the load to leverage the front of the base up and away from the attachment point. It only takes a fraction of an inch to allow water to infiltrate underneath the base, freeze, then expand and pop the guard off the roof.
Guards with flat, forward mounted faces tend to have better leverage against heavy, sustained snow loads. The faces should be perpendicular to the roof panel for maximum holding strength. The image on the left shows the forward-faced snow guard design that we incorporate into all SnoBlox, SnoJax, Icejax and SnowCatcher snow guards. The horizontal screw holes are located just behind the face and as far forward as possible. As the load presses against the face of our snow guards, the base is leveraged downwards towards the screws or adhesive.
