Abstract
Flat-rolled sheet metal is manufactured to preselected gage, mechanical properties and surface finish and is fabricated into unitary sheet metal shingle structures with interlocking folded over sheet metal layers providing for ease of assembly and weatherproofing along each side of a rectangular configuration portion which remains exposed after assembly of shingle structures in side-by-side interlocked relationship in a horizontal direction, and in overlapping partially-covering relationship in a vertical direction. Galvanized mild steel provides lightweight, high-tensile strength, impact-resistant and long-service-life shingle structure. Finish coating enables selection of coloring and thermosetting polymeric coatings facilitate embossing of exposed portions to simulate the appearance of cedar shakes or other types of shingles.
