Abstract: An ice dam removal system comprises a porous container and a deicing component disposed within the container.

Abstract: Apparatus for melting and preventing the formation of roof ice or ice dams on the upper surface of a roof which includes an elongated water-porous container having a closed interior within which a deicing mixture is contained that is composed of a heat-generating deicing agent and a corrosion-inhibiting agent. The container rests on the roof of a building above the ice dam in a transverse, obstructing position relative to the path along which water normally runs so that the water passes through the container and absorbs the deicing mixture to produce a strong deicing brine solution. The brine solution melts any ice it contacts in a medium having a temperature above ?15° Fahrenheit, and inhibits corrosion of associated drains, gutters, etc. Heat-absorbing and ecologically friendly deicing agents may also be added to the mixture to prolong the deicing action and aid surrounding vegetation.
