Preventing Ice Dams During Those Winter Months

Preventing Ice Dams and Winter Home Hazards


As winter approaches, homeowners must be vigilant about potential issues, particularly the formation of ice dams. Ice dams are not only a nuisance but can also lead to serious damage if left unchecked. As a Certified Master Inspector (C.M.I.) and owner of Home Sweet Home Inspections, I've found that many of these problems stem from preventable factors related to maintenance and awareness.


What Causes Ice Dams?


Ice dams form when heat escapes from your living space into the attic, causing the roof to warm and leading to the melting of snow. This melting snow flows down the roof and refreezes at the eaves, creating a barrier that traps additional melting snow. This buildup can lead to water intrusion, potentially damaging your home. Key contributing factors include:


1. Inadequate Attic Insulation

Insufficient insulation allows heat to escape, warming the roof unevenly and accelerating snow melting.


2. Improper Ventilation

Without proper ventilation, cold air is unable to circulate in the attic, leading to fluctuating temperatures that promote the formation of ice dams.


3. Clogged Gutters

Debris accumulation in gutters can obstruct water drainage, resulting in ice buildup on the roof's edge.


4. Unsealed Air Leaks

Gaps around vents, pipes, and other openings allow warm air from the home to escape, further contributing to uneven roof temperatures.
