Asphalt is defined as?

• A. A type of metal
• B. A bituminous waterproofing agent applied to roofing materials during manufacture
• C. A type of wood coating
• D. A mineral used in concrete

Answer: (B)

Asphalt in roofing is a viscous, bituminous material derived from petroleum that acts as the waterproofing binder in shingles. During shingle manufacture, asphalt is applied to the roofing material to provide waterproofing, help bind the granules, and give the shingles the flexibility and weather resistance they need. It’s not a metal, not a wood coating, and not a mineral used in concrete, which is why the option describing it as a bituminous waterproofing agent applied to roofing materials during manufacture is the correct fit.
