There is one final indication that your current home insulation is not cutting it. The good thing about most of these is that they usually don’t require you to get into the attic and take a look at the situation closely.
Should the snow on your roof during the winter start to form ice dams, it definitely means that there is an issue with your current home insulation. Ice dams, as well as icicles, form when the snow on your roof melts and eventually runs down to the edge of the roof.
The problem here is that the water will refreeze again. This will only happen if areas of the roof are warmer than 32 degrees (freezing point) but the edge remains below the freezing point. Even worse, ice dams can prove to be a huge problem depending on the size. They can cause serious damage to the gutters as well as your roof. Worst of all, they require more money to be spent in order to get the fix ! It’s not even a permanent fix.
With proper home insulation, the problem of ice dams can be solved. Even better, it will result in that old and inefficient insulation being done away with entirely. With new home insulation, particularly spray foam insulation, you can have peace of mind in knowing that ice dams are a thing of the past.
