Which item is not listed as a roof-related measure to reduce ember ignition?

• A. Sealed gutters
• B. Class A rated roofing
• C. Proper flashing around projections
• D. Clean gutters

Answer: (A)

The point of this question is to identify which roof-related actions actually help reduce ember ignition. In typical WUI guidance, the measures that matter are using fire-resistant roofing (Class A rating), sealing or flashing around roof projections to prevent ember entry, and keeping gutters clear of debris so embers aren’t trapped and fuel isn’t accumulated on the roof.

Sealed gutters aren’t listed because, while gutter maintenance is important, simply sealing gutters doesn’t directly reduce ember ignition risk the way a fire-resistant roof, proper flashing, or clean gutters do. Sealing gutters can also create other issues, like trapping moisture or debris, without enhancing the roof’s resistance to embers.
