I have heard that ridge vents only work well if there are wide soffits,

On houses with narrow soffits, box vents are recommended.

It seems to me that there might be some failure to communicate here
(the forum). The OP is saying (taken literally) that his SOFFITS are
6", not his soffit VENTS. That leaves very little room for vents and
maybe the roofer thinks he will need fans to pull enough air through?
I don't know enough to offer an opinion on whether that would be
correct...
