Improper roof anchoring ?

So I hired someone to replace the siding on my 2 story home. They used Werner's Workbench Aluminum Pump Jack PJ-WB for scaffolding which requires cables to anquor.

Here's the product link:

And here's a youtube video that shows it in action. I have it timestamped to show the anquors:

Anyway, the job is currently in progress, but my concern is the way they did the achoring. They just nailed (screwed) the metal brackets into my roof, right through a shingle. They didn't even lift the shingle or try to get under it. That seems like bad practice. What's the proper way? I've seen other videos of roof anchors where they put a temporary anchor on the roof peak or at least get under a shingle so the holes you putty later are under a shingle. Or, as shown in the video, it looks like they just connected to the facia board.

Did they do it wrong, thus damaging my roof? What should they have done and how to fix it? I just had the roof put on last month so it's all new shingles. I'm thinking about having the roofer come back and giving me a quote to fix it that I could hand over to the people doing the shingle work.

Nailing through the roof shingles is common practice. Keep in mind that usually this work is being done from a ladder high in the air. One hand on the hammer, one hand on the bracket, one hand on the ladder and another hand to hold up the shingle to nail underneath. Most humans run out of hands so it's a matter of getting it attached quickly and safely. After the job is done it's easy to lift up the shingle's tab and put a dab of sealant between the shingle layers.

Pilot Dane,
Thanks for reply. I totally get that they need to be secured and of course I want them safe.
But in this case there won't be any lifting up of the "shingles tab" they just screwed through the top of the shingle. I'm sure they'll use a dab of sealant when finished, but they'll be no layer on top of it.

Shouldn't this be a concern? They've only done one side section and I assume they'll be moving the scaffolding around the house to do other sides. I'd like to make sure they are doing it properly. Each time they secure it, they are putting 8-16 screw holes in my roof. (I can't tell if it's 2 or 4 holes per bracket).

I tried to take a picture of the anchor. Best I can do for now.

Well, I was hoping for more clarity but I'm out of time.

My own research shows they should either attach the bracket under the tab or, better still, attach to the house some other non-roof way and then finish up with ladders. I'm certain the method they used (just screwing over the top of the shingles) has voided my roof warranty for that section of the roof, but I'm not certain whether or not the tab method would void my warranty. As for the shingles where the just screwed into them, those need to be replaced entirely and even in that case, my warranty is still void for that section of the roof.
