Top 5 Reasons for Installing Snow Guards on Your Metal Roof in 2019

Posted by Kimberly Reichert on Feb 25, 2019 2:17:15 PM

Have you been carefully (or not so carefully) monitoring that gravity-defying overhang of migrating snow that sits atop your roof? Glistening beautifully in the sun, it has stayed up there for days; it will surely stay up a bit longer, right? Sorry, no guarantee. Avalanches are unpredictable and catastrophic events. The snow will fall wherever and whenever it wants to – on you, a loved one, your car or sidewalk.

What is a Rooftop Avalanche? [video]

Posted by Kimberly Reichert on Jan 30, 2019 11:17:24 AM

It is a sudden release of snow off a rooftop. Falling snow forms a temperature-sensitive bond to the surface of a metal roof. As that roof is warmed, (through sun or building heat loss), the bond with the snow is broken and a thin film of melt water lubricates the roof. This sudden release from a rooftop can dump many tons of snow below the eaves in a matter of seconds, endangering building elements, landscape, vehicles and pedestrians.

Qualifying Snow Retention Systems for Metal Roofing, from the Metal Construction Association discusses the rooftop avalanche in the following terms:

Metal roofs provide durable, long-term solutions and have been preferred by many for use in challenging northern and alpine climates where snow and its migration on and from the rooftop is a normal occurrence. Such climates can pose unique challenges for any roof. Pitched roofs of a material that has a slippery surface can pose sliding snow and ice hazards below eaves. In many instances, snow retention systems are installed on these roof types in order to reduce the risk of sudden rooftop avalanche and mitigate the hazards present in the discharge areas below the eaves.

What is a Snow Guard or Snow Retention?

Posted by Kimberly Reichert on Jan 16, 2019 11:47:54 AM

Snow retention helps preserve your metal roof and allows snow drifts and snow melt to exit the roof in a more controlled manner (i.e. in small amounts, evaporation or melt water), avoiding the potential calamity of the rooftop avalanche.

According to the Metal Construction Association's technical document Qualifying Snow Retention Systems for Metal Roofing, a snow retention system, also known as a snow guard system, is a series of unitized snow-guard devices or continuous assemblies installed for the purpose of retaining snow on a roof and allow the snow to evacuate slowly via thaw and sublimation rather than suddenly and unexpectedly via rooftop avalanche.

This is a two-part series featuring the S-5! Snow Guard Calculator. Step 1 covers exactly why it is imperative to engineer your snow guard system and to utilize our online calculator to get the job done. Below, we'll walk you through exactly the calculator's purpose. Then in Step 2, we'll explain exactly how to logon and get started!

Your roof has been developing a perfectly rounded overhang of migrating snow right over your door. It glistens beautifully in the sun and seems to defy gravity as it gets bigger and bigger. But all you can think of is when it is going to fall. That is a smart premonition; because it will at some point. Snow avalanches can be unpredictable and catastrophic events. And the snow will fall wherever and whenever it wants to – on you, a loved one, your car or sidewalk.
