Reducing the risk of ice dams forming will help avoid water damage.

Ice dams are ridges of ice that form at the edge of a roof or around drains and prevent melting snow from draining off your roof. The water that backs up behind this ice dam can leak into the building and cause damage to walls, ceilings, insulation and other areas. Additionally, when the roof doesn’t drain properly, snow, ice and water remains trapped on the roof, adding loads that put your roof at greater risk of collapse.

Safely removing the snow will remove the source of the ice dam.
