Now that we had our first snow, we should keep a close eye on our roof. When ice and snow build up on a roof, you could potentially have an ice dam form up there. Unfortunately, an ice dam could cause major roof damage.
What is an Ice Dam?
An ice dam is a ridge of ice that forms at your roof’s edge. This ridge of ice prevents melting snow from draining off the roof. The ridge causes a large puddle of water on your roof. The water from the puddle can leak into your house and cause damage to insulation, ceilings, walls, and other areas. Your worst-case scenario is for the roof to cave in since it can no longer hold the water. You also run the risk of mold forming in your home where the water sits.
