Roofer added several new metal screws

Hi, About two weeks ago I had a roofer come and do some work on my roof. The roof is around 20 years old, but still holding up well. The company was supposed to remove any old loose fasteners and put in their place new larger fasteners to allow for a proper seal, since the old holes would likely be stripped. However, the guy that "repaired" my fasteners actually just tightened down the old fasteners and put new fasteners next to the existing ones all over the roof. There are 72 new holes in total. Some of these new fasteners are overlapping the edges of the old ones, some are at angles with an obvious seal break. I'm just not sure what I should do about this or how much I should expect the roofer to fix. It isn't just a matter of coming back and putting in the larger fasteners, but i now have 72 more holes that could potentially leak in the future. Am I right to assume that this has decreased the life expectancy of the roof and increased future maintenance? If this happened to you, what would you think is a suitable fix? New panels? Fix the loose fasteners that should have been fixed in the first place? New roof? I just don't know and don't want to be a jerk, but i'm obviously frustrated and don't want to get messed over. You can see the attached pictures for reference. Thanks
