Winter’s beauty can quickly turn into a nightmare for various property owners when ice dams form. These ice ridges along a roof edge can cause serious damage to someone’s home and/or business. This can lead to affecting the contents in the property.  Let’s take a look at what ice dams are and how they affect someone’s property. 

What Are Ice Dams? 

Ice Dams form when water from melting snow runs down the surface of a roof and forms at the edge, preventing the additional melting snow from draining off. This trapped water can then back up under the roof shingles, causing it to leak into your property, or refreeze, causing the ice to lift the shingles off of the roof, causing another way for water to leak into the property. 

How To Identify Ice Dams

Several signs could indicate the presence of an ice dam. Look for these identifying factors:

  • Water or ice inside or around window frames
  • Visible water or ice on the siding of the property
  • Icicles or ice build-up along the roof’s edge or behind gutters
  • Ice in exterior vents along the roof

The Effects of Ice Dams

The consequences of not addressing ice dams can be significant, property owners could face the following: 

  • Roof Damage – As previously stated, water trapped under shingles can cause them to buckle, crack, and/or detach. 
  • Interior Leaks – Water leaking from the roof due to missing/damaged shingles can cause water to leak inside an attic, walls, ceilings, and insulations. 
  • Insulation Damage – Wet insulation loses its purpose which can cause higher energy bills and potential mold growth. 
  • Mold & Mildew Growth – The damp environment created by leaks is ideal for mold and mildew growth, which can pose health risks and further damage to contents and the structure.
  • Damage Gutters – The weight of the ice can damage gutters and downspouts, causing them to sag, detach, and/or collapse.

How To Prevent Them

Prevention is key to avoiding the costly damage associated with ice dams. Some effective actions one can take to prevent ice dams is: 

  • Improve Insulation – Adequate attic insulation is crucial for preventing heat from escaping and warming the roof. Seal air leaks around vents, chimneys, and other openings. 
  • Ensure Proper Ventilation – Proper ventilation, especially in the attic, will help regulate the roof temperature and prevent warm air from being trapped. 
  • Remove Snow From Roof – Regularly removing snow from the roof can prevent ice dams from forming.
