Ice dams can significantly damage the roof causing leaks and many moisture related problems. In most cases, however, ice damming can be prevented or at least minimized with a few simple and relatively inexpensive building envelope improvements.
2. What causes Ice Dams?
25°
Cold outside temperatures,
making the edge of the roof
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.

There are two pieces

Preventing Ice Dams
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.
