Abstract:
An apparatus for preventing formation of ice on a roof, comprising:a sleeve-shaped container formed of a waterproof material having a hollow interior and having generally upper and lower surfaces, at least the lower surface has at least a portion thereof perforated with a plurality of openings, said container being at least partially filled with granular salt;said container being closed near opposing ends thereof with suitable ties to retain the salt within the container; the container being placed upon a roof surface and so that the perforations rest on or near the roof surface, whereby water flowing along the surface of the roof and against said container is drawn through said perforations and into the interior of the container by said salt, and whereby the water drawn into the container is converted into a saline solution which subsequently flows by gravity out through said perforations and onto the roof surface to facilitate the flow of water off of the roof and to prevent water collected on the roof in the region of said container to freeze.
