Generated explanation

The illustration shows an asphalt shingle with cutouts defining tabs and a cutaway exposing its constituent layers. Surface granules cover the asphalt body or coating, which overlies a base material identified as fiberglass mat or organic felt. A self-sealing strip runs across the shingle above the tab cutouts. The exposed layers illustrate shingle composition rather than damage or improper installation.
