What is the concealed space between the top floor and the roof of a structure called?

• A. Cockloft
• B. Eave
• C. Dead Load
• D. Fire Door

Answer: (A)

The term describes a concealed void that sits between the top floor ceiling and the roof structure. This space, known as the cockloft, provides a hidden channel for heat and flames to spread upward quickly, often bypassing ceilings and making fires harder to detect and control. Because it is a hidden area, crews must be mindful of potential fire extension through cocklofts and may need to create openings to vent or search these voids.

For contrast, an eave is simply the edge of the roof overhang; dead load refers to the structural weight that must be carried by the building, not a space; and a fire door is a door designed to resist fire and compartmentalize areas.
