Terrace roofing with thermal insulation dowel

Hello, we have decided to have our terrace roofed. We have finally chosen a provider. We insisted that the attachment to the house be done with thermal insulation anchors. The house is made of clinker and has 20cm thick mineral wool insulation. The roofing is made of aluminum with real glass and measures approximately 8x3.5 meters. Now my question: Is there a standard for how many thermal insulation anchors must be used? I ask this because the roof was first installed without thermal insulation anchors in order to measure the glass wedges and is supposed to be finally mounted next week. During the initial installation, only concrete screws were screwed directly into the clinker. Where can one inquire about this?

Who is responsible for the roof's structural integrity? There is no general answer to that, and there is no standard; it depends on the expected loads and where which loads are to be transferred. If the person calculates that an anchoring solely in the [Klinkerwand] is sufficient, then that's fine, right? If you have doubts about that, you will need to consult a structural engineer who will check it for you.

For better answers, you will need to provide details of the fastening to the wall and the supports in the ground.

So, today the roofing should have been fastened with thermal insulation anchors. The result is that a clinker brick has been pushed in. The roofing company blames the bricklayer. The bricklayer says that if you use such equipment on the masonry, you have to expect that. What do you think?

So, today the roofing was supposed to be fixed with thermal insulation dowels. The result is that a brick was pressed in. The roofing company blames the mason. The mason says that if you use such equipment on masonry, you have to expect that. What do you think?

Of course, if the windowpane had been broken, the window fitter would be to blame... Whoever breaks something is responsible for it.
