![]() ![]() Other fasteners employ a cup-tip and are designed to ‘dig’ into the metal seam to create holding strength. The polish given to the round fastener head ensures the roof’s protective coating is intact, eliminating a place for metal corrosion to begin. The round point of the fastener is designed specifically to dimple the seam without penetrating it, and subsequently stay within the non-penetrating clause of the metal roof manufacturers’ warranty. The dimple is created by the round head of the fastener integrated with a ‘well’ in the snow guard clamp to accommodate the metal seam protrusion on the other side of the seam (Figure 11). ![]() This acts as the active holding point of the fastener. Many snow guard devices employ a mechanically attached fastener with a round, polished head that creates a ‘dimple’ in a standing seam. There is more than one fastener used with attachment devices for metal roofs and they need to be closely scrutinized to ensure they do not harm the roof and attach without voiding the metal roof manufacturers’ warranty. Such products also fall within metal roof manufacturers’ warranties. ![]() We are happy to talk to you or your contractor about the installation method and provide you with the right information and materials to make sure you have a bullet-proof snow retention system that not only looks great but performs exceptionally in the long run.Figure 11: Some modern snow guard attachment clamps attach with round-point non-penetrating screws, which do not harm the roof. What type of installation is recommended than you ask? We like the use of an appropriate sealant along with gasketed commercial metal roof fasteners (like the Woodbinder Eclipse) that will not compromise the integrity of your roof system if installed by a licensed and professional contractor. Therefore, many more are required to stabilize the snow load. Reason 3:Īdhered snow guards have much lower load ratings than mechanically fastened or clamp to seam style snow guards. So, unless snow guards are adhered during the optimum period, closely following manufacturer installation requirements, performance of the adhesives can't be guaranteed. Adhering snow guards is not recommended during the winter months and because of the length of time to fully cure, can't be done in many areas during the shoulder seasons. Reason 2:Īdhesives requires certain conditions in order to cure and these ideal conditions may only exist within a small window of time in many areas where snow retention is desired. Our mission here at Rocky Mountain Snow Guards is to create long lasting, permanent systems that will work as long as you own the building or roof. So, adhered snow guards may work out for the 1st few years but over time, they may come off when a load is applied (like snow piling up behind them). ![]() Reason 1:Īdhesives tend to break down over time. There are a variety of reasons that adhering snow guards onto your roof may an ineffective method in the design of a long-lasting and safe snow retention system. However, if you have called us recently or researched a method of installation for your snow guards you may have noticed that we do not recommend the use of sealant as the sole method of attachment, no matter what the roof type. To be sure, there are a number of manufacturer's that recommend adhering plastic snow guards with adhesive sealant or tape. ![]()
