A servo rotary shingle diverter includes toothed diverter discs disposed along the path of a stream of shingles separated by spaces. In a first or home rotary position, the diverter discs are disposed entirely beneath the shingle path so that shingles pass the diverter discs unimpeded to a first destination. The diverter discs are rotated at the same rate as the moving shingles such that a tooth of the discs moves along with the shingles and into the path of a selected shingle within the gap head of the selected shingle. The discs are stopped when their teeth align to define a ramp and the next selected shingle engages and rides up the ramp and is diverted thereby to a second destination. The diverter discs are then rotated back to their home position. Every other shingle is thus diverted to the second destination while remaining shingles move on to the first destination.
