Tackling the All-Too-Common Issues of Ice Dams and Poor Attic Ventilation

Ice Dam

Hello, and welcome back to the Holda Construction blog! This week, we’re diving a bit deeper into a topic that’s become increasingly common in our line of work, especially in the currently buried-in-winter neighborhoods of Chicago’s Northwest Suburbs. It’s about how a seemingly minor issue like poor attic ventilation can lead to significant problems like ice dams, and what we can do to fix it. While we touched on the topic of ice dams last week, this week we have a wonderful case example of ice dam and attic ventilation issues currently in progress.

Oh, What Beautiful Icicles… or Are They?

Picture this: it’s a crisp, snow day in Inverness, IL. As we pull up to a charming home, the first thing that catches our eye is the picturesque icicles hanging from the eaves. Beautiful, yes, but they’re often a telltale sign of a hidden problem – ice dams. This was not only the case in the home we visited this week, but we’re seeing it regularly as the snow and ice continue across our area.

The Discovery

The homeowner had called us, concerned about some strange water marks on their ceiling. Our team, armed with years of experience, suspected an issue with attic ventilation – and sure enough, our inspection confirmed it.
We started with an exterior examination and immediately noticed the limited soffit vents. In some areas, there were none at all. This was a red flag. A lack of proper ventilation can trap warm air in the attic, melting the snow on the roof, which then refreezes at the eaves, forming those dreaded ice dams.

A Closer Look Inside

But the real story unfolded when we climbed into the attic. The sight was concerning – the fascia showed signs of freezing and moisture, a clear indication of the problem’s severity. Looking at the soffit from inside, it was apparent that there was little to no ventilation. The frost was not just on the roof but inside the home, and we could see visible mold and water damage.

The Risks of Ignoring the Issue

This scenario is more common than most homeowners realize. Ice dams can cause significant damage if left unchecked. They allow water to seep under shingles, leading to leaks and structural damage. The moisture also creates a perfect breeding ground for mold, which can pose serious health risks.

Our Solution

The solution lies in improving attic ventilation. By installing more or better soffit vents, or even rethinking the entire ventilation setup, we can ensure better air circulation. This simple yet effective step can prevent ice dams by maintaining a consistent roof temperature.
Repairing the damage and preventing future issues also involves addressing moisture and mold. Ensuring proper insulation and regular maintenance checks are key to keeping these problems at bay.
We created a short video of an ice dam removal we completed last week – in it, you can see some of the issues addressed if you’re curious:

Conclusion

Located in Chicago’s Northwest Suburbs, at Holda Construction we see cases like this quite often and, each time, we’re reminded of the importance of proper home maintenance.
