The snow has already fallen in many parts of North America.  Some people are already experiencing the damage and trouble that snow build-up and ice dams can cause.  Here are some tips for winterizing your home to prevent ice dams and snow build-up next winter.

1. Clean leaves and debris from your gutters to prevent water from freezing and causing a blockage.  Cleared gutters allow any water underneath snow to effectively run off the roof, instead of getting backed up and causing freezing.
2. Inspect the roof for damaged or curled shingles, corroded flashing or leaky vents.  Repairing these problems in the fall will prevent them from causing more problems during the winter.  Ensure that any questionable areas are repaired or replaced.
3. Check the ventilation in the attic.  As most ice dams are caused by poor ventilation, and warm air rising to the roof and melting the snow, this is the number one prevention tactic to avoid the headache of ice dams.

Taking care of these problems during warmer months, when you can see them, will save you time and money.  Time because you will not be racing the clock before the next snowfall and money because replacing some shingles or having minor repairs done is much less expensive than having your entire roof replaced or repairing any damage to the interior of your home.
