Now that the first snow storm has hit (or the second if you count the one in October), it is time to think about winter maintenance.

One common problem this time of year is ice dams. An ice dam is when melted water freezes at the roof overhang, causing a buildup of water and ice on the roof. The water that is no longer able to drain can become a leak in the house's ceiling. Besides the ceiling, the roof may be damaged by the ice and moisture.

Ice dams can be caused by poor insulation. If too much heat is escaping from the attic, the snow on the roof can melt and flow down to the overhang, where it refreezes. A homeowner might think that his roof needs to be repaired when, in fact, the home’s insulation needs to be improved. Frozen and clogged gutters also do not help, and keeping them clear of debris and ice is important. Finally, keeping the roof clear of heavy snow buildup can help avoid ice dams as well.
