Snow on a Roof

Snow/ice on a roof can present major problems, because snow/ice is basically frozen water. So it is basically equivalent to having water ponding on your roof, which you are aware can cause structural damage.

Interesting fact: Water weighs 62.4 pounds per square feet.

If enough snow/ice is on your roof, the weight alone could cause damage. This is called snow loading. Snow loading is the downward force exerted on structures by the weight of accumulated snow.
