Painter drove nails through roof shingles

I had my house painted. The painter secured new facia boards by driving 4 inch nails through the roof shingles. If I do not fix this eventualy the plywood under the shigles will rot. What is the correct fix for this?

Probably not four inch. Probably three and a half inch 16d. ;) I'm curious. The most likely scenario as you seem to indicate is barge rafter below & flush with the plywood and new fascia covering the existing barge, otherwise the raw plywood edge would be showing above the new fascia.

If the edge of the plywood is showing, you need metal nosing or a shingle mould. That's going to require some serious work now.
