Abstract
A molded hip, ridge or rake shingle is provided that is shaped to fit over angled intersecting planar surface of a roof hip, ridge or rake, by making a shingle precursor and draping it in heated condition over a rack having surfaces that have an included angle therebetween to cool and take form, such that portions of the shingle precursor conform to the surfaces of the rack, at a desired predetermined included angle between the shingle precursor portions, to form a hip, ridge or rake shingle with shingle portions having the desired included angle between the shingle portions. The shingle is formed according to the process, and on an apparatus, to produce the shingles that can be applied to a roof, in an array of shingles.
