Postconsumer shingles have higher asphalt content than manufacturer's waste shingles.

• A. True
• B. False
• C. Not Applicable
• D. Not Sure

Answer: (B)

Asphalt content in reclaimed shingles is influenced by age and exposure. Postconsumer shingles have spent years on roofs and in the weather, which tends to break down and lose some of the asphalt binder, and can also pick up moisture and fines. In contrast, manufacturer’s waste shingles come from the production line and are fresher and more uniform, typically retaining more of their original asphalt content. Because of that, postconsumer shingles generally have lower asphalt content than factory waste shingles, not higher. So the statement isn’t true; you should expect higher binder content in the manufacturer’s waste portion and verify the actual content of any reclaimed material before using it in mixes.
