ABSTRACT:
An ice breaker which is attachable to the top surface of an inclined roof having a V-shaped front edge which lifts and retains the leading edge of a sheet of ice which slides down an inclined roof. The V-shaped edge shears the ice upon further downward movement. The ice breaker further includes a wing with a tapered front portion that acts to shear a sheet of ice that is moving too fast to be retained in the V-shaped portion. The outwardly extending sides of the wing aid in securing a sheet of ice that is already retained in the V-shaped front edge.
