Ice dams prevent your roof from draining properly. Water leaks, mold problems and structural damage can all result, and repair costs can be high. An ice dam occurs when warm air in your attic radiates upward, melting snow on the roof. When the resulting water reaches the bottom of the roof, which is much colder because of less heat in the thin section of underlying attic, it refreezes, resulting in a dam that forces additional melted snow to pool up behind it. That standing water eventually finds its way down into your attic and living spaces.
