Ice Dams can be a little known, but major problem.

We take proactive measures by starting our company vehicles a bit earlier and salting our sidewalks. We also prepare for the possibility that employees may need to stay home more frequently during snow days due to caring for their children. However, there are hidden risks that could jeopardize your business. One such issue is ice dams, which can be a significant problem during the snowy season.

Ice dams form when heated air melts the snow on the roof, allowing water to flow down but then becomes trapped behind still-frozen ice. When this trapped water cannot escape through the gutter system, it can backflow under the shingles and into the interior of the business. This can lead to damaged gutters, shingles, and, ultimately, water intrusion into your building.

Icicles can be an early warning sign of ice dams, as noted by Travelers.com. To check for potential ice dams inside your building, look for water stains or moisture in your attic or along the ceilings of exterior walls. These indications may suggest that an ice dam has formed and water has penetrated the roof membrane.
