There's no question that adding a ridge vent will be worth the cost (by
keeping the insulation dryer it will actually lower the heating bills) but
the inspector is also questioning the soffit venting. I would trust his
instincts and look closer at improving the soffit venting as well. You may
find that this will consume the better part of your venting dollar.
A good philosophy to follow is, you can never have too much venting in an
attic, and good air flow (not blocked or restricted).
