Ice dams are caused by non-uniform roof surface temperatures.   When there is heat loss, snow cover and fluctuating outside temperature, there is a risk of ice dams forming.   Here are a few ways to help with ice dam prevention:

• Remove snow from your roof, especially if you start to see icicles forming.
• Check your attic or rafter space for adequate insulation.
• Make sure your roof system has good ventilation for appropriate ice dam prevention.
• Make sure all penetrations through your ceiling are sealed and insulated.

By doing some prevention, this could help to avoid any insurance claims and costly repairs on your home.  Contact a local roofing contractor that you trust if you need help or suggestions on keeping your home free from ice dams or for prevention help.
