In this country there seems to be two reasons for fitting roof vents.
One is, if the roof is leaking, then the movement of air will help dry it out, the other, that water vapour created inside the home, will rise through the ceilings and holes in the ceilings and condense on the cold roof timbers, perhaps a dozen or so times a year, with the potential to create wood rot.
If you go up there with a bright light, you will see if the rafters have water marks on them from a leaking roof and if a lot of water vapour is rising from your home and condensing on the timbers.
If the roof isn't leaking and if there is no sign of wood rot, ignore the coment.
