Ice dams are not just a roof problem. They are a heat, air, and moisture problem wearing a roof disguise.
Stop heat loss first
Warm indoor air leaking into the attic melts roof snow from below. Air sealing and insulation help keep the roof deck cold.
Keep attic air moving
Balanced intake and exhaust vents help flush moisture and heat so snow melt is less likely to refreeze at the eaves.
Protect vulnerable edges
Ice and water barrier, clean eave details, and gutter planning reduce damage if winter conditions overpower the system.
