ABSTRACT:
A user-friendly roof rake is provided to readily remove snow from a roof. The lightweight roof rake has a special plastic blade with a rounded contour to pull, curl and rapidly remove snow from a roof. The roof rake-blade can be reinforced with a series of curved ribs and can have an array of downwardly extending ribs that provide rounded teeth to prevent the lower leading edge of the blade from digging into the shingles or otherwise damaging the roof. The convenient roof rake has an expandable multi-piece handle, which preferably comprises a set of snap-fitting interlocking metal tubes that can be readily assembled and expanded for use, and can be easily dissembled for storage. The metal tubes of the handle can be thermally insulated and more easily gripped with a ribbed plastic sleeve. The outer portions of the roof rake-blade can be reinforced by stabilizing struts or braces.
