Abstract
An ice melting and clearing rod includes an ice melting chemical compound including calcium chloride, sodium chloride, potassium chloride, amide, and/or glycol, forming a substantially cylindrical member. The substantially cylindrical member includes: an outer surface including: multiple grooves that run along a length of the cylindrical member, the grooves being evenly spaced about a circumference of the cylindrical member; and a textured surface along at least a portion of the outer surface, the textured surface providing resistance in one direction along the length of the cylindrical member; and a set of through-holes adapted for use as placement features, wherein each through-hole in the set of through-holes is perpendicular to the length of the cylindrical member, where: the rod is adapted for use on a sloped roof, the outer surface is formed by the ice melting compound, and a shape of the substantially cylindrical member is retained without any external container.
