Ice Dams
Wind-Driven Rain
Water from melting
snow over the heated
portion of the house
runs down the roof.
It freezes at the cold
eave and an ice dam
begins to form prevent-
ing drainage.
As the ice dam grows,
water is trapped
behind it and backs
up under the shingles.
Eventually it reaches
the roof deck and
leaks through, damag-
ing the interior of the
structure.
Grace Ice & Water
Shield
®
HT membrane
resists this leakage
because of the seal
around the fasteners,
ability to make water-
tight laps, and the
membrane’s bond to
the deck.
Sloped roofs are not
waterproof. They
protect structures by
shedding rain water.
Storm-driven winds
can cause sloped roof
coverings to lift. Rain
can then be easily
driven under the roof
covering directly to the
unprotected roof deck
where it causes leaks
and damage to the
interior of the structure.
Grace Ice & Water
Shield
®
HT membrane
applied beneath the
sloped roof cover-
ing helps prevent
wind-driven rain from
entering the structure.
