Valley questions about nails and cut overlap - replace?

I’m new to doing inspections and came across a shingle roof that had nails all through the valley (not 6" away). It’s a cut valley and the high slope shingles go under the low slope shingles. Valley metal underneath. Homeowner just bought the house and wants recommendations.

If there is no visible leak from the valleys yet, is replacing them unnecessary? Or is it better to be proactive and recommend replacing the entire valleys?

Absolutely need to be replaced.

It’s not a matter of if, it’s a matter of when it will leak. Replace now.

The lower slope shingles should be going under the higher or bigger slope shingles.
