What are the basic components of asphalt shingle construction?

The basic components of asphalt shingle construction are indeed best represented by the combination of base, body, surface granules, and self-sealing strip.

Asphalt shingles are primarily composed of a fiberglass or organic mat (the base), which provides strength and support. On top of this base, a layer of asphalt is applied (the body), which adds waterproofing properties. The surface granules serve several purposes, including providing UV protection, adding color, and enhancing the aesthetic appeal of the shingles. Additionally, the self-sealing strip, which is a strip of adhesive, holds the shingles in place once they are applied to the roof and helps prevent wind uplift.

Understanding these components is essential for recognizing how asphalt shingles protect a roof, how they are installed, and their durability over time. The inclusion of surface granules and a self-sealing strip distinguishes this answer as the most comprehensive representation of asphalt shingle components.
