Ice damming occurs when snow accumulates on the roof and is then melted by heat loss from inside the home and/or direct sunlight. This melting water then proceeds toward the eaves where it refreezes, creating an ice dam at the edges of the roof and along the gutters.
With frigid temperatures upon us, ice damming will often occur on slate or tile roofs, which can lead to extensive damage to the interior of one’s home.

With the ongoing freeze and then thaw, ice and snow begin to buildup on the edge of the roof and cannot drain away.
