Ice dams are dangerous masses of ice that build up along the edges of pitched roofs. They develop when heat escapes from your attic and begins to melt snow built up on the roof. As the water flows down the roof, it may refreeze when it passes over a cold expanse of the roof. This typically happens at the eaves (the lowest edge of the roof) because eaves protrude beyond the wall of the house, making them less susceptible to the warming effects of heat leaks
Ice dams create a barrier at the edge of the roof. The melted snow pools behind the dam, causing water to seep under the shingles. The ice opens up the holes and pries open the shingles in the roof when this process continues to happen, leading to leaking and water damage to the roof, attic, and ceilings in the home.
The Dangers of Ice Dams
Ice dams are dangerous — they can slide off a roof with enough force to injure people and damage property. They can also cause significant damage to your shingles, gutters, and downspouts. Some homeowners mistakenly neglect the removal of heavy snow from the roof or don’t consider checking for ice dams. It’s important to learn proper methods for ice dam removal so you can avoid costly repairs and keep your family and guests safe.
The longer ice dams remain in place, the bigger problem they become and the more likely they are to cause damage. The leakage caused by ice dams can ultimately lead to indoor mold growth.
Preventing Ice Dams
It’s fairly easy to avoid problems related to ice dams. They are caused by inadequate air sealing and insulation between the living space of your home and the attic. Common culprits for leaking heat include vent pipes, recessed light fixtures, chimneys, attic access ways (pull-down ladders and hatches), heating ducts, and bath and kitchen exhaust vents. Ice dams can also be prevented by installing roof vents that allow hot air to escape. When attic air stays cool, it does not warm the roof and melts the snow. Snow removal is much easier than ice dam removal.
You can use a push broom or roof rake to clear as much of the snow and ice off your roof as possible – especially before the next round of heavy melting. When it comes to removing stubborn ice dams or preventing the structural damage they cause, it’s often easiest and most effective to call for professional help. Working with professionals who are prepared with the right tools, training and experience protects both your personal safety and the integrity of your home.
