Ice dams are one of the biggest pains to deal with, especially during the spring, when all of the ice starts melting. In the past few months, we have seen that the weather can get extremely warm and then get extremely cold, within the course of a few days (and even hours). What this can do, is make already created ice dams even worse.
These ice dams can lead to quite a few problems, from falling ice to water damage on your home. Similarly, when people try to remove these ice dams themselves, there can be a few issues, as this ice can fall and hurt the individual trying to remove it. It can also fall down and do damage to your home, or passersby.
But how can you avoid any of these problems? By adding insulation of course!
Ice dams form in a very interesting way. It first begins when there is a bit of snowfall. This snow then creates a layer on your home. From here, the heat from the inside of the home leaks out and then heats the snow from underneath. The melted snow rushes to the edge of your roof, where it refreezes when it hits the cold air once again. The ice will continue to form until it gets warm enough for it to completely melt.
Insulation, which helps to keep the temperature of your consistent, does not allow for this warm air to leak out of your roof. This means that the snow cannot be heated from the bottom, and therefore it will not turn liquid and refreeze into this ice, which has caused so many issues in the past.
