What (animal?) made a 0.75" diameter hole through my asphalt shingles?
I call them manufacture burn holes, I see them in most roofs even roofs only 1 year old, it is normally where there are either loose stone or poor seal of the stones on the shingle and with out the stones there is no protection and the sun will burn right thru the asphalt, it looks like your in this picture had some help with insects or yellow jackets, normally it just goes to the fiber or the shingle below, here is picture of one year old roof, just starting to deteriorate,
