I would suggest contacting the shingle manufacturer and request an
on site manufacturer's rep. The issue may be able to be handled
by phone, but you may be headed for problems with the roofer and
having the rep on site would add much to the total conversation.

My house just had a complete roof tearoff and application of 50
year
architectural asphalt shingles over 30 lb. felt and 1/2" CDX
plywood.
The roofers finished last Friday, and I see some exposed nails
and they
presumably replaced some shingles, therefore. Going up there now
I see
more exposed nails. Some I can see standing over them, maybe
half of the
nail head (1.25" galvanized roofing nails). Many more, I can see
from
the side, if I look up the slope of the roof. I figure those are
less
exposed than the ones you can see from above, but some moisture
is going
to reach those nails too. How exposed does a roofing nail in
this
circumstance have to be before it presents a problem? Thanks
for the
information.
