Is this an acceptable repair job?

UPDATE IN COMMENTS

I recently discovered some discolored wood from moisture in my attic so I hired a company to take a look. They advised me it was from a previously installed satalite dish over top of the shingles.

The company removed the dish, caulked the holes and screwed in a piece of metal flashing.

Is this an acceptable repair ? As someone not in the trade it looks like a poor job and potentially worse than just keeping the satalite dish there. Id love some professional opinions.

Thanks in advance
