A roofing tile which has a corrugated thin top wall (11) with an upper shelf (17). The tile is slopingly angled and contains an overhang on the lower edge such that overlapping is accomplished when layed contiguously on a roof (13). One lateral edge includes an upwardly facing shelf or pocket (71) having a pair of beads (77) defining a rain trough (79). An overhang flange (41) on the opposite edge allows the tiles to nest forming a water resistant joint. A support grid (15) is formed by a number of intersecting longitudinally diagonally and transversely extending wall segments integrally formed with the top wall provide a sturdy support. The shelf further contains a number of sockets (21) and the overhang (19) contains a matingly shaped flange member (23) which join together when layed one on the other creating an indexing interface aligning the tiles together and preventing slipping apart. A pair of nails are driven into the roof through holes (69) to further attach the tiles.
