In the Northeast and Middle Atlantic United States, icy and snowy winters are commonplace. Although the results of these winter storms can be pretty to look at, they unfortunately wreak havoc on a home's roofing and gutter system. The most serious of these effects is the development of ice dams. With professional assistance from Bergen County roofing experts, homeowners can learn about and how to correct some of the most common causes of ice dams.
Weather is the most common reason why ice dams form, but homeowners have no control over whether an ice storm forms in their area. If such a storm is forecast, homeowners can have roofers check to make sure that the gutters are clear. Heating tapes can also be installed as a preventive measure. This allows property owners to be prepared for any kind of weather problems.
Incorrectly vented exhaust ducts are another common cause of ice dam formation. Not only does this warm air create warm spots on the roof where snow can melt and then refreeze during the cold night, but the humidity from the exhaust vents also renders the insulation less effective. All vents should open to the outdoors.

Roofers can extend vents that empty into the attic by adding longer ducts and creating an opening in the roof. The perimeter of the opening will be equipped with flashing and caulking to prevent water seepage. Poorly insulated heating ducts also allow warm air to leak into the attic. Roofing crews can wrap duct tape and fiberglass insulation around the duct work to prevent this problem.
Interior heat escaping to the attic is another reason why ice dams develop on some, but not all, roofs in a neighborhood. Attics that are poorly insulated allow warm air to escape through the roof's wooden decking and exterior shingles or tiles. This warm air typically escapes during the day and causes snow on the roof to melt. Then at night, the melted water refreezes and pushes its way underneath the shingles to form an ice dam. Before winter arrives, homeowners can have their roofers check the attic to make sure that it contains the U.S. Department of Energy's recommended amount of insulation based on the home's location and building materials.
Roofing underlayment that is in disrepair or that is not waterproof also allows ice dams to form. The underlayment is the last layer of material protecting the roof's wooden interior structures from moisture. Once water has passed through this layer, an interior water leak may be inevitable. Fortunately, installing a waterproof underlay can prevent moisture penetration.
