The vent apron vent is a polypropylene vent which enables warm air to escape from the lower roof void or through the barge detail of a mono pitch skillion roof. Achieving calculated continuous and unimpeded airflow through the roof cavity is relatively straight forward. Mono pitched roofs are also known by the names of skillion roofs shed roofs pent roof and lean to roof.

Eaves soffits and fascias. Divisions of the building product design group. Figure 5 mono pitch roof next to be discussed will be flat roof construction.
