Causes of Ice Dams

According to the National Weather Service, ice dams are formed when the temperatures fall below 32 degrees Fahrenheit and are found mainly on low slope roofs. Some common causes of ice dams include poor ventilation and insulation in the attic, placement of heating in the attic, and recessed lighting near the roof.

How Can Ice Dams Damage My Commercial Roof?

There are two common ways ice dams cause damage to commercial roofs.

1. Freezing Water

Freezing water can damage the roof because it expands and can tear the sealing points along the roof’s edge when it freezes. Additionally, large icicles can accumulate at the roof’s edge, and the weight of the icicles can damage the roof and the eavestrough or rain gutter.

2. Pooling Water

If water pools behind an ice dam, it may seep into your commercial building because it has nowhere to drain. Pooling water can cause extensive damage to the structure of the building as well as to the insulation, drywall, and electrical systems.
