- Ice Dams are created when the Hot Moist Air Rises from the Interior of the Building.
- Any snow built up on the roof will now also thaw and refreeze at the gutter area and build up eventually working its way under the shingles and into the home.
- As the Hot Moist Air Rises into the Attic and meets the Roof Framing System. Condensation Occurs on the Cold Framing Members consisting of: Rafters, Roof Trusses, Roof Decking
- As the Condensation Cools the Moisture in the Air Freezes on the Roof System and is why venting the attic is suggested.
