Winter - effect of snow Part2

So the snow built up until February 7th at about noon. That was when the snow guards holding back such a mass of weight said "no more". The courtyard area has a standing seam metal roof that pitches toward it and had built up with quite a curl of snow. I estimate that it was 4ft thick of ice and dense snow and went back a good 20ft from the eave toward the ridge of the roof.

Heavy snow weights about 20lbs/cubic foot. 4ft tall drift x 60ft long gutter x 20ft from eave upward = 4800 cubic feet of snow, or 96,000 pounds. That my friends is a lot of weight. Snow guards were torn free, and it crashed into the courtyard.

We have a mini excavator handy and dug a path to see what was buried. The inverter obviously took a hit on the roof as you can see from this photo. It is made to withstand outdoor environments, but never was envisioned to be under such a blast of weight. The blue canopy shown in other photos over the inverter was a light gauge cover to shelter a technician when they would service the equipment. Needless to say, it was destroyed.

The inside corner also house the air conditioning condenser unit. We created a canopy cover to protect the unit from snow during the winter time. Little did we know it would be crushed under the impact.

So my next post will discuss the recovery from the event.
