An ice dam can damage both your roof and the inside of your home.
Hot roof ice dam.
Ice dams and icicles form when the snow melts runs down your roof and refreezes near the edge.
You do that by increasing ventilation adding insulation and sealing off every possible air leak that might warm the underside of the roof.
Just keep the entire roof the same temperature as the eaves.
Be sure to inspect the roof surface from outside for leaks and damage every year and to fix any damage quickly.
For an ice dam to form the warm parts of the roof generally need to be higher than 32 degrees f while the cold areas of the roof need to be below 32 degrees f this means that the outside temperatures must also be below 32 degrees f.
This only occurs when part of your roof warms to above 32 degrees f warm enough to melt the snow while the roof edge remains below freezing.
