ABSTRACT:
An elongated, substantially V-shaped roof panel and a roof panel interlocking method using the V-shaped roof panel, having the inclined sides of the V-shaped roof panel provided with elongated stair-stepping reinforcement ribs for purposes of producing a more rigid and stronger roof panel. At the terminating ends of each of the inclined sides there is provided a complementary mechanical lock design that produces a roof panel lock when a first terminating end member, of a plurality of identical roof panels, is mated with an adjoining second terminating end member of a plurality of identical roof panels. Each terminating end mechanical lock design is comprised of various bends in material, shaped such that when adjoining ends of a plurality of identical roof panels are interlocked, the various bends of each lock design are in a closely coupled relationship. The shape of the various bends in each end lock design is attributed with achieving an increasingly tighter bond between roof panels with increasingly higher wind forces experienced. The shape of the various bends used to produce a better lock, coincidentally creates a mini-gutter at the lock which helps prevent water siphoning at the lock and solves a problem which heretofore has not been succesfully solved.
