How to Prevent Ice Dams on Your Roof

As you walk into your home this winter you might think “Wow, look at this winter wonderland that my home has become with all of these icicles.” But in reality, large icicles hanging on the edges of your roof and gutter system are an obvious sign of an ice dam. If there’s one thing you should focus on this winter, it’s preventing ice dams from forming on your home.

What Exactly is an Ice Dam?
Naturally, the temperature inside of your home is going to be a whole lot warmer than the outside. However, when your attic space isn’t properly insulated or ventilated, the warm air on the inside can melt any snow and ice sitting atop your roof. Water will begin to trickle downwards off of your roof, but some of it will freeze on it’s way down — thus creating ice dams. It’s important to avoid ice dams as the melted ice can find its way into the structure of the roof where it can cause water damage.

Ice Dam Protection

  • Additional Ventilation – Attics need to be properly insulated to prevent warm air (from within the house) from entering the attic space. In addition to attic insulation, many roofs will need to have vents installed to relieve the attic of any warm air that might have found its way into this space.
  • Extra Underlayment – Some homes will also need an extra layer of underlayment between the shingles and structure of the roof. The edges and eaves of the roof are the most common areas where additional underlayment is needed.

Ice dams can cause severe damage to the roof of your home, which could end up costing you thousands of dollars in repairs.
