Asses the situation and ask these questions, are there safety concerns? Is there water coming inside the house? If the answer to these questions is no then there is a good chance that no action is the best action. Ice dams are occurring all around us, at the same time and for the same reasons. Most will go untreated and all will eventually reduce and disappear as nature takes its course.
Some suggestions that might help. If ice on the ground is a problem it may be possible to rope off an area and not allow traffic under the ice until it resolves itself. Typically ice dams are not a problem in and of themselves. If yours is problematic I suggest calling a reputable local roofing contractor to help with your issue. You can expect prices from $350.00 to $1000.00 or more. The down side to removal is that the dam may return given similar conditions and there could be some collateral damage to shingles or gutters. Give me a call I would be happy to walk you through your unique situation.
