This question pertains to asphalt shingles.
I have seen some roofs with the metal drip edge and some without.
Is the metal drip edge always installed, implying that no drip edge is an
oversight or worse?
It seems to me that w/o the drip strip the rain would wick under the
bottom
layers and cause grief.
Thank you,

Drip edge was almost never used back in the days when roofs were constructed
with 1 X stock.

I am not sure when it came into wide use. If I had an older home with an
older roof without it I would not worry. When I replaced the roof I would
use drip edge even if the roof was 1 X lumber.

If you have seen a fairly new roof built with OSB or plywood and it did not
have drip edge you have seen one **** poor roofing job.
