How much snow is too much?

Hanover Insurance Group has posted a new item, ‘How much snow is too much’?

As we brace for another snowstorm, many communities are dealing with as much as 50+ inches of snow. These record amounts of snowfall can lead to buildup of too much heavy snow on the roofs, decks, carports and awnings of homes and businesses. Left unattended, this weight can cause damage or even collapse.
