Some individual buildings may melt snow and ice with electric heating elements buried in the pavement, or even on a roof to prevent ice dams on the shingles, or to keep massive chunks of snow and dangerous icicles from collapsing on anyone below. Small areas of pavement can be kept ice-free by circulating heated liquids in embedded piping systems.
An ice dam is an ice build-up on the eaves of sloped roofs of heated buildings that results from melting snow under a snow pack reaching the eave and freezing there. Freezing at the eave impedes the drainage of meltwater, which adds to the ice dam and causes backup of the meltwater, which may cause water leakage into the roof and consequent ...
There are several ways dams can be removed and the chosen method will depend on many factors. The size and type of the dam, the amount of sediment behind the dam, the aquatic environment below the dam, who owns the dam and what their priorities are, and the timeframe of dam removal are all factors that affect how the dam will be removed.

When the meltwater reaches the freezing air, ice accumulates, forming a dam, and snow that melts later cannot drain properly through the dam. [87] Ice dams may result in damaged building materials or in damage or injury when the ice dam falls off or from attempts to remove ice dams. The melting results from heat passing through the roof under ...
