What is the term for the small space created when a roof is raised above the level of ceiling joists to provide pitch for drainage?

Explanation:
This term names the small void between the ceiling and the roof that is created to give the roof its slope for drainage. It sits just above the ceiling and below the roof, usually not a usable living space, and in older buildings it’s where drainage pipes or services can run and where access is limited to a hatch or trap door. Because it’s a hidden space, it can also become a pathway for fire to travel, which is why knowing its location matters. Attic, loft, or garret describe larger upper spaces or living areas rather than this specific, narrow void whose purpose is to provide drainage slope.
