No it isn't. Roofs have vents and crown or cover boards have holes. Two different pieces of equipment with two different orifices.
Roofs shouldn't have vents either - unless your foolish enough to believe you need a gaping hole in the crown board to facilitate a chimney effect (as actually recommended in last month's BBKA comic)
