2. Concrete and clay

3. Asphalt and fiberglass

4. Slate and resin

The correct answer is: Asphalt and fiberglass

Asphalt shingles are primarily composed of asphalt and fiberglass. The asphalt serves as a waterproofing agent, making the shingles effective in protecting the roof from moisture and adverse weather conditions. Fiberglass, often used as a reinforcing mat, provides added strength and flexibility to the shingles, enhancing their durability and resistance to tearing or cracking. In practice, this combination of materials allows asphalt shingles to be lightweight while still offering excellent performance in terms of both waterproofing and longevity. Additionally, asphalt shingles are popular due to their cost-effectiveness and ease of installation compared to other roofing materials. This composition plays a crucial role in the overall functionality and appeal of asphalt shingles in the roofing market.
