We are getting quotes for a new roof. One said they would replace two older style roof vents (not up to code anymore) with one larger one. (We aren't sure if he means one new vent for every two old ones....) Two other companies say they would take out all of the old vents and put in a ridge vent.

We have 7 of the old style vents.

Is one type of vent better than another?
