Stopping Ice Dams Before They Start

It’s fall in Minnesota, and Minneapolis/Saint Cloud homeowners can get a lot of mileage out of taking the next few weeks to prepare for the winter weather that is ahead. One of the most common concerns among area homeowners is the issue of ice dams, which can cause a great deal of roof damage. In many homes, ice dams are a yearly concern that never seems to go away.
Rather than dealing with them when they occur, taking the time to stop ice dams before they start is the best way to keep your home from suffering damage this winter.
Ice dam issues begin when heat rises through the home via a process called the “stack effect,” which inevitably reaches the roof (via your attic) and begins to melt the snow that sits there. As the snow melts, water begins to trickle to the edge of the roof, where it quickly freezes due to the lack of residual heat. The result? A block of ice at the edge of your roof that traps water, allowing it to pool and build up along your roof, causing irreversible damage in a relatively short period of time.
Why are ice dams worth paying attention to? Quite simply, they can cause structural damage to your home, added wear and tear on your heating system and moisture problems, which can result in dangerous mold and indoor air quality (IAQ) issues. Clearly, this is a problem that should not go overlooked.
At RetroGreen, we see ice dams on a regular basis and know just how problematic they can be. There are plenty of contractors who will perform simple “band aid” fixes on ice dams once they form, but the problem inevitably comes back around. Instead, it’s important that homeowners focus on beefing up insulation and ensuring that their homes are properly air sealed. This will also allow your heating system to operate better, since the heat that caused the ice dams to begin with won’t be escaping your home as readily.
Insulation and air sealing play major roles in the overall structural integrity of the home. The trained home performance specialists at RetroGreen have the knowledge and experience it takes to ensure that ice dams never again become a problem in your home, no matter how bad the issue might currently be.

Chris didn't start RetroGreen Energy because he wanted to be in the insulation business. He started it because he wanted to fix homes the right way.
After earning his BPI Building Analyst certification and Minnesota Building Contractor license, Chris spent years studying how homes perform as systems. He saw firsthand that most comfort and energy problems weren't caused by old windows or outdated furnaces — they were caused by air leakage and inadequate insulation that nobody was diagnosing properly.
In 2009, he launched RetroGreen Energy with a commitment to doing things differently. Every project would start with proper diagnostics. Every recommendation would be based on data, not sales targets. And every homeowner would get the honest truth about what their home actually needed.
