Tray Ventilation

Because of their relatively narrow ribs, tray roofing generally self ventilates less than other roof profiles. This puts more responsibility on the designer to consider ventilation of the ceiling space. Ventilation is particularly important for fully supported profiles; the ply must have a gap at the apex to allow for egress of air and a gap at the bottom, or soffit vents, to allow air ingress.
