Claim:
A grain storage system comprising: a housing including; a first side wall and a second side wall, each of said first and second side walls engaging and extending upwardly from a ground surface; a roof structure being attached to and extending between said first and second side walls, said roof structure including a plurality of roof trusses, each of said roof trusses including an inner chord, said roof trusses being laterally spaced from each other; a plurality of panels being attached to said roof structure to define an auxiliary storage capacity above said first and second side walls supported by said roof structure, each of said panels extending between and being attached to adjacently positioned ones of said inner chords, said panels each being horizontally oriented; each of said panels being elongated, each of said panels having; a first end, a second end, an upper edge, a lower edge, an inner surface and an outer surface; an upper bend being positioned adjacent to said upper edge, an upper flange being defined between said upper bend and said upper edge; a lower bend being positioned adjacent to said lower edge, a lower flange being defined between said lower bend and said lower edge; a primary bend being positioned between said upper and lower bends, said upper and lower flanges each being attached to said inner chord, said primary bend being spaced further from said inner chord than said upper and lower bends; said upper flange including a first section being continuous with said upper edge and a second section being continuous with said upper bend, said first and second sections each lying in planes orientated parallel to each other and being spaced from each other, a medial section being defined extending between and being attached to each of said first and second sections, said first section being spaced from said inner chord when said second section is abutted against said inner chord; and said first section of each of said panels forming a lip extending over lower flanges of adjacently positioned ones of said panels to form a continuous inner wall extending upwardly along said inner chords to a predetermined height, said lower edges of said adjacently positioned ones of said panels abutting an associated one of said medial sections.
