Thanks
Yeah, by remove I meant the whole thing and plugging up the holes. If necessary I have access to disable them.
The roof is only 5 years old, so if I don't remove them the boxes will be there for a while unless there's storm damage or similar.
If it was my house at the time I would have had a ridge vent put on rather than the box vents. Maybe they were just re-using existing vent holes.
The soffit is aluminum and has like a 6x12" vent every 8 feet or so. I'd like to increase that to full vent around the house to improve air flow. Yes, I'm aware of using baffles.
I have a pro that I would use to install the vented soffit. He'll get it done in a day or two, while it would take me a week and a lot of choice words.
The ridge vent is simple enough that I could tackle that in an afternoon.

It's difficult to cap them off from the inside because there isn't much to fasten to except the roof sheathing. You could simply wad up some insulation and stuff it in the holes. Maybe cut a wood plug and jamb it in the opening. If you have sufficient soffit vents and a sufficient ridge vent, nothing else is necessary. But leaving the box vents open probably won't hurt anything. Plug the holes in the sheathing and toss the box vents when you get a new roof.
The soffit should be vented the entire length, Not just every couple feet. Do you have vinyl soffit? The ridge vent should run between the 2nd truss on each end of the gable.
I find it interesting when I go out west and new homes have box vents. They haven't been used for new construction on the east coast for probably 30 years with the exception of areas that ridge vents aren't feasible.. like porch "Shed style" roofs or shed style roofs on additions. Don't forget to install baffles for new soffit vents.
Some builders in south Texas were still using vents as recently as two years ago in higher end custom homes.
