Abstract
A fastenable composite roofing shingle is made from a composition comprising an organic, resinous material and an inorganic filler material, the shingle having a structure comprising a top surface forming an upper, headlap portion and a lower, butt portion, with the headlap portion having one or more targets suitable for indicating a desired fastener location to a shingle installer. The targets include a recessed area in the top surface of the shingle to enable a head of a fastener to be sheltered below the top surface. The recessed area has a hollow dimple defining an area of additional indentation, whereby the thickness of the shingle in the recessed area is greater than the thickness of the shingle in the dimple.
