Mid-Faced Snow Guards Stops

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.

Before marketing our products, we send all of our guards to the ATI professional testing lab in York, PA. Our tests have achieved strength ratings up to 6300 lbs.  Visit www.SpacingTool.com for a free layout and estimate for your project.  Our guards are guaranteed for the life of the roof!

Snow Guards That Break up Snow and Ice

Snow guards are designed to hold snow and ice until it can melt.  This doesn’t increase the load on the roof structure, it simply holds the load longer.  Many times we are asked how to control sliding snow and ice on roofs were holding the snow is not a desired option.  The solution is our patented SnowBreaker product.  It is inexpensive and has proven to be very effective at controlling snow and ice slides while still allowing the load to leave the roof safely in small pieces. This effectively minimizes the dangers associated with falling snow and ice on  metal roofs or an array of solar panels.

These snow guards are designed with a forward mounted cutting edge that breaks up snow and ice instead of holding it in place.  It still controls the danger of sudden avalanching snow but allows the load to leave the roof in a shorter amount of time as compared to a flat faced snow guard.
The SnowBreaker product can be installed with screws, adhesive, or with a combination of 3M VHB peel n stick tape plus adhesive around the perimeter

Primitive Snow Guards

Snow guards of various materials including stones, logs, and fencing have been used for hundreds of years.  These bulky, primitive systems helped to protect the roofs from sudden slides and also insulated the structures from extreme weather.  Early systems were made of materials that were collected locally and installed with little regard for cosmetics.  Early roofing materials were not as slippery as modern metal panels, but still required snow retention methods in extreme cases.
