The Dangers of Ice Dams on Roofs

By December 31, 2021 January 25th, 2022 No Comments

Ice dams can cause severe damage to your building. Ice dams form at the edges of a roof, where the snow melted by the heat from within a home or commercial building accumulates and freezes again when it is shaded from the sun by both the structure itself and its overhanging eaves.

This accumulation of ice on the under-eaves side causes an ice dam. Ice dams can cause water to back up under your roof covering, tear off gutters, and loosen shingles. Water that cannot drain off will work its way under the roof covering and into the attic space where it can leak through insulation, ceilings, walls, and other areas of a structure. Ice dams are often seen with older buildings that are poorly insulated, have insufficient attic ventilation, or are located in climates where it snows heavily. Ice dams can also form under rubber roofs. Ice dams are especially dangerous to commercial properties which often contain flammable materials and other hazards.

The presence of ice dams creates a domino effect. Ice dams damage gutters and downspouts, which can lead to leaking or overflow problems. Ice dams also cause water to back up under the roof covering, leading to ice-packed snow that will put extra weight on your roofing system. Ice dams can weaken roof structures and loosen shingles, which will eventually lead to other problems if left unchecked. Ice dams may be a problem with any commercial roofing system, including flat roofs. Ice dams can cause severe damage to your building.
