Living in the Madison and Milwaukee areas, bitterly cold, snowy, and icy winters are not new thing to us Wisconsinites. Just because we’re used to the freezing cold, doesn’t mean that our homes are protected against the elements of winter – specifically the forming of ice dams and the lasting problems they can cause.
Before we talk about how ice dams are formed, let’s talk about what an ice dam is. An ice dam is a ridge of ice that forms on the edge of a roof. It prevents melting snow from draining, which then backs up behind the ice (or dam), and can eventually back up enough to cause leakage into your home.
There are two ways that ice dams form.
Once the moisture has built up behind the ice dam, a leak starts in the attic of your home. Where there is a leak, there is mold. Mold thrives on moisture and grows quickly, feeding on the organic materials in your home – wood, drywall, wallpaper, carpet, etc. Our homes have the perfect temperature that mold needs to thrive, between 5-38 degrees. Mold will continue to feed on your home, and can eventually affect the structure causing lasting damage if left untreated.
Like we discussed, ice dams form when heat escapes from the attic. This means that the attic temperature must be hot enough to heat the roof and melt the snow. The thing is, your home does not have to be heated to high temperatures for heat to hit the attic!
Things we do on a normal basis like bathing, laundry, washing dishes, cooking – all of these things can cause the temperature to rise IF the attic is NOT insulated properly. Check your attic insulation before winter hits and replace any worn insulation to keep the attic at an appropriate temperature.
Another cause of heat or condensation in the attic is lack of ventilation. Steam and heat rise, and if there is not a ventilation fan installed in the kitchen or the bathroom, the steam and humidity from your cooking or shower has nowhere to go but up! It will get to the attic through crawl spaces or air vents, and build up to cause high temperatures.
The good news is that ice dams are preventable! Aside from making sure that your attic is properly insulated and that your home is ventilated as needed, here are the best ways to prevent ice dams.
While you can spot ice dams on your roof, there are also ways to make sure that your attic does not have any condensation issues. Check it regularly and look for the following.
