Preventing Ice Dams: Key Insights and Solutions for Your Home

Ice dams are a serious winter issue that can lead to roof leaks, water damage, and costly repairs. Understanding the causes of ice dams and using the right diagnostic tools can help
prevent these problems before they start. According to the University of Minnesota’s research, factors like poor air sealing, inadequate attic insulation, and insufficient ventilation play a major role.

How Do Ice Dams Form?

Ice dams form when warm air from your home leaks into the attic, heating the roof and causing snow to melt. The water runs down to the eaves, where it refreezes and forms a dam. This buildup traps additional water, which can seep into your roof and cause damage. The main issues contributing to this process are inadequate air sealing, insufficient insulation, and poor
attic ventilation.

Diagnostic Tools: Blower Door Testing and Infrared Camera Analysis

A blower door test measures how airtight your home is, helping identify air leaks that contribute to ice dam formation. Infrared camera analysis complements this by providing a thermal image of your home, showing areas where insulation may be missing or insufficient.

Understanding Zone Pressure Diagnostics

Zone pressure diagnostics help detect hidden air leaks that are not obvious during a visual inspection. By measuring pressure differences, we can identify pathways where warm air is escaping into the attic, contributing to uneven snow melt and ice dam formation.

Improving Your Home’s Air Sealing and Ventilation

Effective air sealing prevents warm air from escaping into the attic, while proper ventilation helps cool the roof deck and vent out moisture. Addressing these issues can significantly reduce the risk of ice dams and improve your home’s energy efficiency.
