Do you have enough openings in the soffit to allow for
good air flow?

This is a very good question to get answered. My neighbor had them
installed and the roof knew they would be useless with the cathedral
ceilings but did not advise him. I think they chared him about $1200
USD and they are pretty much worthless.

On a cathedral ceiling, ridge vent is about the only way you can go. There
should be an air gap between sheathing & insulation. Or, baffles so the
insulation isn't against the sheathing. The baffles create the air gap.

You can't put pod/pot vents on and be effective, nor can you install gable
end vents for the same reason.
