Abstract: A rail mounting system for mounting skylights and the like directly to rib elevations of a raised rib panel roofing system has a side rail for each side of a skylight or run of skylights that mount to the metal panel roof's rib elevations. Each side rail includes a vertical riser wall, an upper flange structure extending from the riser wall to provide a top bearing surface for one side of a skylight or run of skylights, and bottom shoulder structure extending from the raiser portion, which is adapted for attachment to a rib elevation of a raised rib panel roofing system. The rib elevations on which the side rails of the rail mounting system are attached provide structural support for the skylight or run of skylights supported on the side rails for substantially the entire length of the skylights or run of skylights.

Abstract: A rail mounting system is provided for mounting skylights and other structures directly to rib elevations of a metal panel roofing system. The rail mounting system has a side rail for each side of a skylight or run of skylights that mount to the metal panel roof's rib elevations. Each side rail includes a vertical riser wall, an upper flange extending from the riser wall to provide a top bearing surface for one side of a skylight or run of skylights, and a bottom shoulder structure extending from the riser portion which is adapted for attachment to a rib elevation of the roofing system. The rib elevations on which the side rails of the rail mounting system are attached provide structural support for the skylight or run of skylights supported thereon for substantially the entire length of the skylights or run of skylights.

Abstract: The invention provides a system for installing a roof penetrating structure to a metal roof, the system comprising: a) a rail and closure structure adapted to be supported by adjacent rib elevations of said roof; b) a skylight adapted to be supported on the rail and closure structure; and c) a support member for sealing a cut away portion of the rib structure to divert water away from the rail and closure structure.

Abstract: A skylight having an arched main body, an apex, a base, and corrugations is described. The main body has two lengths, the first being at substantially the apex and the second at the base wherein the first length is less than the second length. The skylight also has a first end portion and a second end portion at opposing ends of the main body, each of which has a top and bottom section. The distance between the top sections define the first length and the distance between the bottom sections defines the second length. The corrugations disposed on the main body vary by orientation, method of manufacture, number, and shape.
