Nashville gets an average of 4.2 inches of snowfall each year. However, in 2021, Nashville recorded 5.2 inches of snow. Knowing your roof’s maximum snow load will be critical with ever-fluctuating weather patterns. Here is some information about roof snow loads from the Insurance Institute of Business and Home Safety:

Know your roof’s maximum snow load

When it comes to the weight of snow, the type of snow is as important as the depth of the snow. For instance, fresh powder snow is typically lighter than wet packed snow, and ice is heavier than snow.

Snow Load Danger signs

Fresh snow – more than four feet

Packed snow – more than two feet

Ice – one inch or more

Several factors contribute to the acting load on your roof, including snow drifts from adjacent buildings or mechanical equipment, heavy rain on snow, and melting snow that refreezes. 

If you don’t know your roof’s snow load, hire a structural engineer to verify the snow load threshold of the roofing system. This information will be important when determining if there is too much snow on the roof after an event.
