A rail mounting system is provided for mounting and supporting skylights and/or other structures to rib elevations of a metal panel roofing system. The rail mounting system includes first and second side rails which can be mounted to the rib elevations of the metal panel roof. Each side rail includes a riser, an upper flange extending from the riser, and a bottom shoulder structure extending from the riser. The bottom shoulder structure can be mounted to a rib elevation of the roofing system. The upper flange provides a top bearing surface for supporting one side of a skylight, or run of skylights, or other structures, which are supported from the roof by the rail mounting system. The rib elevations to which the side rails are mounted provide structural support for the skylight or skylights supported thereon for substantially the entire length of the skylight or skylights or other supported structure.
