At Northside Company, we know ice damming in Rochester, NY is a frustrating issue for many homeowners during winter. Ice dams form when warm air escapes into the attic, melting snow on the roof, which then refreezes at the eaves. This cycle can lead to roof leaks, moisture buildup, and potential water damage—but it’s not something that can be solved by simply replacing your roof. The key factors in managing ice dams are attic ventilation, insulation, and overall home efficiency.
We understand that ice damming is a complicated issue, and we get a lot of calls from homeowners asking about solutions. To help clarify how attic ventilation affects your roof, we put together a short video that explains what homeowners should know about roof insulation, ventilation, and temperature regulation.

Why Ice Damming Happens
Ice dams occur when attic temperature is uneven, often due to poor insulation and inadequate roof ventilation. Warm air rises from your home, melts the snow on the roof, and as that water trickles down to the colder eaves, it refreezes. Over time, this ice buildup can block proper drainage, leading to shingle damage, leaks, and interior water issues.
Many homeowners assume that a new roof will eliminate ice damming, but the reality is that it’s a complex issue influenced by multiple factors. That’s why understanding how attic ventilation works is so important.
The Role of Proper Attic Ventilation
While roof ventilation alone won’t prevent ice dams, it plays an essential role in regulating attic temperature and reducing moisture buildup. A well-ventilated attic helps warm air escape and allows cool air to circulate, which can extend the life of your roofing system and minimize related issues like mold growth, wood rot, and insulation damage.
