I'm looking into buying a new house here in Wisconsin that has soffit vents, ridge vents and some additional static roof vents installed. However, when the home inspector came through he said that combining ridge vents and roof/static vents is a problem because it can cause the air to short cycle and the attic won't vent properly, leaving moisture trapped. He said ideally you should have one intake system (the soffit vents) and one outtake system (the ridge vents).
The builder told me that the reason the static/roof vents were added was because the carpenter had made a mistake cutting holes for the trusses (or something like that, I'm not a handyman so didn't totally understand) and to fix it they just decided to add these roof/static vents over the holes, thinking that it would simply improve venting for the attic.
My question is, is the home inspector right and I should be asking for the roof/static vents to be removed/closed, or is it fine to leave them in?
Inspector's report (ignore stuff about baffles):
