Disclosed is an insulated metal roofing system which includes channel shaped roofing panels locked together in side-by-side relationship at the upwardly projecting edges of the channel legs by means of interlocking flanges, with legs of adjacent panels in abutting relationship. In some embodiments specially configured clip members engage the roofing panels in their regions of abutment and project downwardly therefrom. Channel shaped ceiling panels are hung in side-by-side relationship on the clip members, and part or all of the space between the roofing panels and the ceiling panels is filled with insulation. The clip members are preferably constructed to provide a selection of points of connection between them and the ceiling panels to thereby provide a selection of spacings between the roofing panels and the ceiling panels. In another embodiment, the ceiling panels are connected directly to the roofing panels.
