If you expect to have snow on your roof the following may be helpful:

1.In most cases, ice dams can be prevented by proper insulation and ventilation. Because a main cause of ice dams is an overly warm attic, it’s advisable to keep your attic as cold as possible. A well-designed attic will have good air exchange with the outside air and is physically and thermally isolated from the living space below. Make sure your ventilation system is properly sized and unobstructed. Additionally, ensure that your attic is properly insulated.  Seal all penetrations that will allow air to flow into the attic from the living spaces.  This can include attic doors and hatches, any exhaust (bathroom fans, whole house fans, etc),and any other ceiling penetrations such as recessed lighting.

2. Take notice of sections of the roof with accelerated snowmelt. This can be an indication of excessive heat getting into the attic.  You may see this associated with an uninsulated attic entry hatch.  Improved insulation under this area may correct this situation, but a thorough inspection of the attic would be recommended.

3. Penetrations that have been sealed in the past still need to be inspected to ensure that any weather stripping and/or insulation is intact and functioning properly, such as on attic stairways or hatchways.

4. If your attic ventilation system does not generate sufficient air movement to dissipate the heat, you can improve ventilation with a motorized vent. Inspect your attic to be certain that existing vents are functioning properly.

5.Typical ventilation for venting is 1 square foot for every 150 feet of attic floor area. If your home does not have this ratio, consult with a contractor to make the necessary adjustment.
