A mono-pitched roof has a single sloping roof plane, which isn’t attached to any other roof plane in any way.
Where the pitch (slope) of a mono-pitched roof is minimal or negligible, it’s then simply referred to as a flat roof, or perhaps a sunroof or terrace roof depending on its use.
Different countries have defined a minimum pitch (slope) for a roof to be considered a mono-pitched roof:
- US: min. 10°
- UK: min. 10–12.5°
- NL: min. 15°
