Vaulted ceiling ventilation

[Bobbarebygg]

Hi! I'm not sure if I'm in the wrong forum section.

I'm wondering about what is correct regarding the ventilation of the air gap in a pitched roof.
Is it okay to have it sealed at the ridge and only open at the eaves? That is, metal sheet, battens, vapor barrier, counter battens, masonite.

I've searched here on the forum back and forth and keep landing on a lot of other questions that don't concern me.

We have just converted the roof of the house to a ridge roof and the company that did it took it for granted to have an air gap and ventilation at the ridge and eaves... The other two quotes we received before the construction also included air gap and ridge ventilation, so I assume that is what applies...
What would be the advantages of not having ridge ventilation?

Best regards,

Daggen

You can use Mögelstoppers if you don’t want a ventilated ridge.

Daggen 84: what type of ventilation do you have? on the gables or along the ridge?
Katos: yes, I have seen those mold stoppers, but mostly wonder if it's necessary to have a ventilated ridge? or if you can just have it open at the eaves (and of course a ventilated gap for the entire roof)

They installed 4 "chimneys," one between each pair of rafters so the air can ventilate out... I was a bit surprised myself when I came to the cabin and there were a lot of chimneys on the roof
There are probably much more discreet solutions, but I still think it turned out quite okay and a bit different.
