Which term describes the additional layer of roofing material at the eaves to help prevent damage from water back-up?

• A. Downspout
• B. Felt
• C. Feathering strips
• D. Eaves flashing

Answer: (D)

The main idea here is understanding edge protection at the eaves that stops water from backing up and causing leaks. Eaves flashing is a metal strip installed along the eave edge, typically under the shingles and over the underlayment, that seals the roof edge and directs water into the gutter. This edge piece prevents water from seeping behind the roofing at the eave, which can lead to leaks in the attic or soffit and helps reduce ice dam and wind-driven rain damage. Downspouts are part of the gutter system that carries water away from the building and aren’t a roofing edge protection. Felt is the general underlayment beneath the shingles, providing a moisture barrier but not specifically addressing water back-up at the eave edge. Feathering strips aren’t a standard feature for edge protection at the eaves. So, the term that best describes the protective edge at the eaves is eaves flashing.
