Abstract
Apparatus for providing double coverings or claddings has a stiff support piece shaped to fit in a bottom portion of a corrugation of a pre-existing roof covering. The support piece attaches to subjacent purlins through the pre-existing covering. The support piece has a generally U-shaped section including a base coopertively shaped for being seated in the corrugation with upper edges of the U-shaped section being folded back horizontally so as to provide two seats for engaging an upper purlin. The laterally disposed ends of the seats are raised at right angles to form abutments. An upper purlin is attached to the abutments of the support piece. The upper purlin is a reversed U-shaped metallic section having side wings. The wings have edges folded back horizontally and outwardly.
