Heavy snow puts stress on rooftops across Minnesota, Wisconsin

This recent bout of heavy snow has really put our roofs to the test. In fact, some rooftops even collapsed this past weekend, including the Old Zumbrota Bridge and a garage in Rhinelander, Wisconsin.

So, how can homeowners keep this from happening?

Sagging ceiling, cracks in the drywall, and lower-hanging sprinkler heads are all signs that your roof is covered in too much snow. 

According to structural engineer Josh Herzog with Herzog Engineering, the biggest issue is that we’ve had a lot of snow in a short amount of time, meaning it’s not really melting.

You should also consider how long the snow has been on your roof and if it is dry and fluffy or packed.
Herzog recommends keeping fresh snow at about 3 feet or less and packed snow at 2 feet or less.

Additionally, a shed, barn or detached garage might not handle as much as your home can.
