Horsefeathers are tapered wood filler strips placed along the butts of old wood shingles to create a level surface when reroofing over existing wood shingle roofs. What are they also called?

• A. Nail pops.
• B. Ventilation baffles.
• C. Feathering strips.
• D. Roofing cement.

Answer: (C)

The main idea is recognizing the name for a finishing strip used when you overlay new shingles over old ones. These tapered filler strips are placed along the butts of the old shingles to create a level, smooth surface for the new roof. They’re called feathering strips because their tapered edges “feather” into the old surface, helping the new shingles seat evenly. They’re not nail pops (protruding nail heads), not ventilation baffles (for attic airflow), and not roofing cement (for sealing leaks).
