Fixing an awning - What is technically correct with an ETICS?

During a further "inspection" of the mounting situation in the course of deciding exactly how wide the awning should be, another question arose for us. Regarding the situation: The multi-family house has two identical apartments on the ground floor and the upper floor respectively. At the very top (attic floor) there is one apartment that spans the entire width of the house. This apartment also has a roof terrace that extends across the entire width. This owner has had a canopy (glass + awnings underneath) with supports etc. installed over about 2/3 or 3/4 of the terrace. The balconies of the two apartments on the upper floor have (built-in) canopies. Since the roof terrace is recessed as usual, i.e., within the building area and does not protrude like a balcony from the building, everything from the roof of the attic terrace then extends over the roofs of the upper floor balconies. Now, specifically to the problem. The owner of the attic apartment has had his roof extended even wider than the two balcony roofs of the upper floor apartments combined. This means the roof of the attic apartment overhangs by about 1m on both sides. As in the past winter with all the heavy snow loads, we then have the problem that snow avalanches from the roof of the attic terrace land directly on our terrace. Aside from the fact that this is already life-threatening, the question arises regarding the awning: Is this bad for the awning we have planned? The drop area is exactly the area where the awning would be installed, i.e., the "box" of the awning (is it called the cassette?). I assume that neither the awning (the fabric certainly not, but that is not extended in winter anyway), nor the mounting are designed for such loads/impacts... because those are always quite massive amounts of snow that fall down and of course gain considerable speed from the attic down to the ground floor. PS: The canopy was indeed installed immediately after the completion of the multi-family house, but without any approval from the homeowners' association.
