Roof drain de-icer apparatus

A method of preventing the formation of ice on the lower part of the roof and in a roof drain comprising the steps of:

• a. providing a flexible plastic sleeve-shaped container formed of a waterproof material, said container having an upper and lower surface and having a hollow interior and having one end tied with closing means;
• b. perforating a portion of at least one of said surfaces with a plurality of openings;
• c. filling granulated salt within the hollow interior of the container;
• d. tying an opposing end of the container with closing means to retain said salt within the container;
• e. arranging said container with the enclosed salt on said roof with the perforated container surface facing the surface of the roof, whereby water flowing down the roof is drawn into the container by said salt and subsequently discharged as a saline solution through the holes in the lower surface of the container to the surface of the roof and towards the roof drain.

An apparatus for preventing formation of ice on a roof, comprising:

• a solid block of pressed, granular salt having at least one substantially flat surface for supporting the block upon a surface of the roof;
• and
• at least a top surface of said block opposite said flat surface having a waterproof coating directly applied to said block to protect the block from rapid deterioration due to precipitation;
• wherein said waterproof coating is a coating of wax.
