Other things to consider are whether or not the system has been independently tested and if the system can be designed/engineered for your specific roof. This will ensure roofline aesthetics for years to come as you won’t have to worry about your snow guards fading at a different rate than your roof panels. Preferred systems will use flat stock panel that has been cut down to slide in the face of your rail/extrusion. Both individual and rail-type snow guards give you the option to color match your roof panel. Rail-type snow guards are commonly manufactured from aircraft quality, high-tensile aluminum and use stainless steel hardware for attaching. Either of these two methods will then use a continuous rail/extrusion that attaches to either the mount or clamp, and will also have a SNO-DAM or a flag that hangs down and rests in the center of the flat of the panel, which will keep snow and ice from sliding under your snow guards.
Continuous rail-type snow guards will attach to either a mount that is through fastened into a structural member, for corrugated or through fastened panels, or via clamps that will attach to the seam of a standing seam panel, using non-penetrating setscrews. These pad-style snow guards are typically polycarbonate, and do not usually offer the same strength characteristics of a continuous rail system. Individual snow guards will either adhere to the roof panel via adhesive/sealant or fasteners that penetrate through the roof panel into the structural substrate. There are many configurations of snow guards on the market but individual/pad style snow guards and continuous rail type snow guards, such as DYNA-GUARD, are the two most commonly used in the U.S.īoth can be installed on through fastened panels or standing seam panels. This decision will be based on what type of roof panel you have or perhaps as simple as what type of look you want. Plus, if your building has trees nearby it, snow guards will allow debris like tree branched or leaves to fall off the roof as opposed to snow rails that will catch that debris and require regular maintenance to clear it.When realizing that snow retention is a critical component of your metal roof, your first question is what type to use. Their staggered pattern installation helps with breaking up snow and letting it fall in smaller chunks at a slower rate compare to using a snow rail system that does a good job letting the snow melt, but doesn’t break it up as much.

They are easy to install and have several different designs that fit most roofs. Typically on residential and small roofs, snow guards are the preferred choice. With the proper number of clamps, these systems could prove stronger than their snow guard counterparts. Some people however are not too fond of the way these systems look when installed, or see the appeal of using lower-costing snow guards.
If you have a larger roof and cost is not too much of a concern, a continuous snow retention system might be a better option for you. These all play a factor when you’re deciding which would be better for your project. Your decision on whether to use snow guards or snow rails can be based on a variety of things.
