ᐅ Patio roof with thermal insulation anchors

Hello, we have decided to have our terrace roofed. We finally chose a provider.
We insisted that the attachment to the house be done using thermal insulation anchors. The house has a brick facade and a 20cm (8 inch) thick mineral wool insulation layer.
The roofing is made of aluminum with real glass and measures approximately 8 x 3.5 meters (26 x 11.5 feet).
Now my question: Is there a standard specifying how many thermal insulation anchors must be used? I ask because the roof was initially installed without thermal insulation anchors to measure the glass spacers and is scheduled to be fully installed next week. During the first installation, only concrete screws were directly screwed into the brick facade.
Where can I inquire about this?

Who is responsible for the structural engineering of the roof? There is no one-size-fits-all answer, and no fixed standard, as it depends on the expected loads and where those loads need to be transferred. If the person calculating determines that anchoring solely in the brick wall is sufficient, then that should be fine. If you have doubts, you will need to consult a structural engineer who can review it for you.

For more accurate answers, you will need to provide details of the wall fastenings and the supports in the floor.

So, today the roof covering was supposed to be fixed using thermal insulation anchors. The result is that a brick was pushed in. The roofing company blames the mason. The mason says that when working on masonry with such equipment, this must be expected. What do you think?

Of course, if the windowpane had broken, it would have been the glazier’s fault...

Whoever causes damage is responsible for it.
