This invention provides a panel assembly for buildings and the like comprising, in combination with structure supporting the assembly, an array of overlapping elongated metal panels, each panel including a lower edge, an upper flange, and a web including at least one outwardly protruding longitudinally extending stiffening rib. The stiffening rib adjacent the upper flange has an elongated longitudinally extending groove and an extended bearing portion for contacting the structure when the panel is fastened thereto. These ribs provide structural support without purlins, sheathing, or the like. A plurality of fasteners for attaching the panel assembly to the structure pierce the extended bearing portion hold the bearing portion in contact with the structure so that when panels are affixed to the structure with the lower edge of one panel overlapping the upper flange of another panel, the groove forms a space between overlapping panels to prevent water from flowing around the stiffening rib adjacent the upper flange.
