Can Snow On Your Roof Be a Good Thing? & Ice Dam Solutions
Ice dams form around the edges or eaves of your roof and are caused by melted snow/ice from your roof that gets refrozen when it reaches the edges/eaves. This occurs in homes that have ventilation and/or insulation problems and can be harmful to your home, cause leaks, and be dangerous to anyone unlucky enough to be standing underneath the dangling ice.
Heat can leak out of your attic and melt the snow on your roof in many ways:
As you can see, there are many different contributing factors that create an ice dam. The best thing you can do is look for permanent solutions like increasing ventilation, adding insulation, and sealing and caulking air leaks in your ductwork and attic. The key to preventing ice dams from accumulating is by keeping your entire roof cold, not just the eaves. This is accomplished by preventing as much heated, conditioned air from entering your attic as possible. Inspect your attic and upper story ceiling for any cracks.
Quick Ice Dam Prevention:
There is an easy trick to prevent ice dams this winter: fill nylon stockings with calcium chloride ice melt and place along the edges of your roof and around your gutters.

Long-term tips: improve attic insulation, check that soffits are unobstructed, seal structural leaks around walls/ceiling/attic, and weatherstrip your attic hatch.
Here is a map that shows Common Air Leaks:
It is important to winterize your entire home and check for air leaks around the exterior of your home while you are at it. If you combined all the air leaks in the average home, you would have a hole with a diameter of 3 feet in an exterior wall!
Most roofs are designed to withstand a significant amount of snowfall, but when the snow is very compact and wet, it can sometimes be too great of a burden for your roof to handle. With older roofs especially, it is advised that you speak with a roofing contractor. They will have a better answer for whether or not your roof can handle the load and will be able to clear your roof and ice dams safely.
