nail pops are showing up now. Thanks again.

Maybe the extra weight of the additional roof. BTW how many layers of
roofing is there now? In 40 years I would guess this is at least the second
new roof to be put on and if both the original and first replacement are now
under the second (or third) replacement you are carrying too much weight up
there.
