Bathroom roof vent for a flat roof

I’ve had a chronic problem with a leaking bathroom vent during storms (like this one). I thought I fixed it last month when I found some exposed flashing around the vent on the roof. Apparently not. I think now that the vent shroud was intended for a pitched, not flat roof. It appears that this vent was intended to have its opening pointing “downhill”, which of course it can’t with a flat roof.

What kind of vent should I have? Is there a name for it?
