Which term describes the practice of applying fine mineral matter to the back side of shingles to prevent sticking in bundles?

• A. Fine mineral matter applied to the back side of shingles to prevent sticking in bundles
• B. Back surfacing
• C. Asphalt roofing cement
• D. Algae discoloration

Answer: (B)

Back surfacing is the term for applying a fine mineral matter to the back of shingles to keep them from sticking together in bundles. This creates a dry, nonstick surface so shingles can be easily separated during handling, storage, and shipment. The other options describe either a different concept (asphalt roofing cement, which is used as a sealant) or a cosmetic issue (algae discoloration), or simply restate the practice without naming the standard term. Using the established term helps ensure clear communication in manuals and on the job site.
