Wintertime in Montana brings cold temperatures, snow, and ice. The presence of snow and icicles on your roof may look pretty, but they could be pointing to a serious problem on your roof: ice dams!
Ice dams are a common problem in Montana as well as other areas of the country with lots of cold and snow. But how are they formed and how can you prevent them? Find out below.
Ice dams are thick ridges of solid ice that build up along the eaves of your house. They often occur when warm air in the attic space heats the underside of the roof, causing the existing snow to melt. The water then makes its way down the roof, eventually coming in contact with the deck over the eaves, which is not exposed to heat from the attic. This is where the water re-freezes and builds up ice, blocking the subsequent run-off and creating a “dam.”
There are several signs that may indicate the presence of an ice dam:
Ice dams cause water to back up under your roof’s shingles and drain into your home. The water works its way under your roof, covering and flows into the attic. Eventually, it will drip into the insulation, ceilings, exterior walls, and other areas, causing ruined paint and sheetrock, stained and sagging ceilings, warped floors, and even mold and mildew.
If the ice dam breaks free, it can pull shingles and gutters off with it, damaging anything it falls on: shrubs, windowsills, cars, pets, and people.
The main cause of ice dams is poor insulation and vent space under the roof. The best way to prevent an ice dam is to seal all points where warm air leaks out, insulate the areas where the warm air is coming from to prevent conduction and convection of heat through the ceiling, and vent the space between the insulation and the roof sheathing, so any heat that does leak through is carried away.
A few other tips for preventing ice dams include:
If your home does suffer water damage, it is important to turn to restoration professionals to minimize risk to your health and safety. The severity of water damage can range from category 1 to 3:
Hiring a professional team allows you to protect yourself from potential exposure to harmful bacteria and pathogens that could lead to severe illness. It will also ensure that the cleanup process is completed correctly the first time.
