A shingle includes a body having a top surface, a bottom surface, an upper end, a lower end, a first side, and a second side. The body has a width defined as the distance between the first and second sides and a length defined by the distance between the upper and lower ends. In a preferred embodiment, the shingle also includes a water diverter tab attached to the first side for channeling water onto the top surface of a lower adjacent shingle, and a recess adjacent to the second side for receiving the water diverter tab of a laterally adjacent shingle in an interlocking manner. An anchor tab attached to the second side secures the lower ends of adjacent, interlocked shingles.
