What is an
Ice Dam & Why it's Important to Remove Ice Dams
What is an ice dam?

occur when snow accumulates on the slanted roof of a
house with inadequate insulation and warm air leaks
into the attic at penetrations for plumbing stacks,
wiring, chimneys, attic hatches, recessed lights,
etc. These warm air leaks are known as attic
What causes ice dams?
Ice dams form
when melted snow flows down the roof, under the
blanket of snow, onto the eave and into the gutter,
where colder conditions on the overhang cause it to
freeze. Eventually, ice accumulates along the eave
and in the gutter. Snow that melts later cannot
drain properly through the ice on the eave and in
How ice dams form on your roof:
- Heat rises through the ceiling into the
attic warming the surface of the roof.
- With the warming roof, snow melts and
flows down until it reaches that part of the
roof that of the outside temperature. Thus,
re-freezing the water into ice or a block of
ice known as an ice dam.
- The snow continues to melt but because
of the of ice blocking and filling the
gutter system, the water does not drain
- Eventually, the water backs up
under the shingles, penetrating cracks in
the roof covering flowing in to the attic,
soaking the insulation and eventually making
it's way to the ceilings and walls. Once
this happens, the water damage is done.
