The Impact Of Insulation On Ice Damming

The Impact Of Insulation On Ice Damming

If you have ever experienced an ice dam on your roof, then you know how damaging it can be to your roof and the rest of your home. Ice dams can be prevented, though, and it starts with proper installation of attic insulation.

With a sufficient amount of attic insulation and proper attic ventilation, there should be no cause for an ice dam to form. Ice dams form because the attic air is warm enough to melt snow on the roof while the eave of the roof remains cold enough to freeze the water as it trickles down. If your attic insulation is installed correctly, the warm air should not penetrate the attic to begin with. If heat does penetrate, then the attic vents should be open and plentiful enough to allow that air out of the attic before it can melt the snow.
