A corrugated waterproof roof covering has a plurality of adjacently positioned sections. Each section includes an intermediate series of separated, adjacently positioned ridges interconnected by identical U-shaped channels. An additional lowered ridge is located at a first end of the series of ridges and appends from them by an L-shaped channel. An outer edge of the lowered ridge appends to a shallow U-shaped channel. The sections are positioned in edgewise overlying relation. An end ridge at a second end of each section overlies and receives the lowered ridge of an adjacent section to create a passageway therebetween and to laterally interlock the sections. A protective layer is positioned atop the rides, and fasteners extend through the layer for termination in the passageway for concealing the fasteners from view.
