It's a _NEW_ house acceptance inspection apparently...

I read it the other way, but it is unclear whether it is a new new
house or a new to the OP house.

Sounds like the installer got in too big a hurry and got a few nailed
too low.

I think the roofer was probably hammered.

Only 17 nails in a whole roof isn't much although strictly speaking of
course there shouldn't be any.

It only takes one nail to cause a leak. The OP has a potential
collander.

They'll probably do worse trying to repair it than it will be to simply
use a little roof cement over them and go on for that few if they're
scattered around hither and yon.

Well, that depends on the shingles. Three tabs are easy to pull and
repair. Laminated are a bit tougher, but a competent roofer who had a
slate ripper would have no problem either way.

If they're all in one area so could remove/replace a small contiguous
area and get 'em all, then you might consider having them do so.
Otherwise, the damage done trying to replace a single shingle here and
there probably outweighs the likelihood of these ever being a real problem.

I would tend to agree with the assessment. Pull the nails, neatly
fill the nail holes with roofing cement (caulking gun), and press some
shingle granules (enough will usually be found in the gutter) into the
roofing cement to protect the roof caulk and make the holes disappear.
