I have heard that ridge vents only work well if there are wide soffits,
like 12" or more.

On houses with narrow soffits, box vents are recommended.

Any truth to this?

Your roofer sees a problem with using ridge vents and isn't explaining why
very well. Perhaps you should talk to more roofers. If you have already
hired him perhaps you could get him to elaborate.
