Modular roofing system

A modular roofing system for overlying a base structure comprising:

• a plurality of elongated modules having identical cross-sections, each module including a principal body member defining a planar upper surface for the module and an interior guideway their in accessible from the underside thereof, wherein the interior guideway for the principal body member defines a keyway aperture, the module also includes a planar web having a free edge extending form the principal body member and defining a bottom surface for the module, said body member further includes one underside surface coplanar with the bottom surface of the planar web and a second underside surface displaced from the bottom surface sufficiently to receive the planar web of an adjacent module thereunder, and a locking member engaged to the free edge of the planar web, said locking member having a vertically extending strip having an upper and a lower end, wherein the locking member includes a terminal bead at the upper end thereof adapted to be received in a mating relationship within a keyway aperture of an adjacent module so that said modules are disposed in successive tiers with the locking member of a module in one tier mating within the keyway aperture of the adjacent module in the next tier, to lock adjacent modules against vertical displacement;
• and
• a plurality of overlyng covering members affixed to the planar upper surface of the principal body members.

A readily assembled module roof structure for overlayment on a base structure and comprising:

• a plurality of modules of like cross-section, the modules each comprising integral elongated units having a principal body along an axis of elongation and a web extending normal thereto, and also comprising a male member coupled to the web at a spaced apart region from the principal body, wherein the male member is integrally attached to the free end of the web and comprises a vertically extending member and a terminal bead mounted on the upper end of said vertical member and means defining a female recess in the principal body for receiving the male member of an adjacent module in mating relation, wherein the female recess in the principal body is accessible from the underside thereof, both the female recess and the male member extending parallel to the axis of elongation of the module and so spaced that successive rows of modules may be joined together in side-by-side relation and precisely placed by the mating relationship therebetween;
• and
• means disposed along the webs for attaching the individual modules to the base structure;
• and
• surface cover means coupled to the principal body of each module to overlie at least the next lower row.

A module roof structure for placement on a base structure comprising:

• a plurality of modules of like cross-section, the modules each comprising integral elongated units having a principal body along an axis of elongation, a web extending normal thereto, and including a male member integrally attached to the free end of the web, said male member comprising a vertically extending strip and a terminal bead mounted on the upper end of said strip, said principal body including means defining a female recess therein for receiving the male member in mating relationship, said female recess defining a keyway aperture accessible from the underside of said principal body, said strip and said terminal bead on said male member being received in said keyway aperture through the underside of said principal body for locking adjacent modules together against vertical displacement relative to the roof, the free end of said web passing below one part of the surface of the principal body of an adjacent module, both the keyway structure and the male member extending parallel to the axis of elongation of said modules and so spaced that successive vertically displaced modules may be joined together and precisely placed in parallel relation by the mating relationship therebetween, the principal body of said modules having a planar upper surface and a planar lower surface supported on said base structure;
• a plurality of shingles positioned on said upper planar surface of a module and of sufficient length to overlap shingles on at least the adjacent module;
• rivet means disposed along the webs for attaching the individual modules to the base structure;
• and
• rivet means for attaching said shingles to the upper surface of said modules.
