2. What causes Ice Dams?

cold enough to freeze melting
snow on contact.
Heated air escaping through the
attic and heating the top
of the roof, causing the snow to
melt.

4. Step 1: Get Rid of Snow
If it is cold outside - between 15° to 25° -
use a snow rake or stiff broom to remove
as much of the snow from the roof as
possible.

5. Step 2: Keep the Attic Cool
Have your attic professionally
air sealed, to prevent heated
air leakages.
Add insulation to increase
R-Value and prevent heat
transfers through the ceiling.
