Panels JA Solar 550W, 2280mm Deye 8kW IBR, not sure, haven't measured

I had 10 panels, portrait mounted at 30 degrees, in two rows on a flat ibr roof. The problem is that the rows were mounted north-facing, so they did not align with the beams under the ibr and last weekend's wind took everything out. We managed to salvage 9 of the panels (one even fell onto tar below but didn't break). Once the mounts started to break free from the roof it was a mess of bending, shearing and loose panels. Now the panels have to be remounted but, obviously, I'm cautious. Firstly, I am worried about the previous mounting 'approach' - there is quite a lot of overhang of panel above the highest point of contact with the mounting structure and,secondly, I don't know how to get more proper anchor points into the wood beams if we go north-facing again. Does anyone have advice on this? Do I need to add cross beams of some sort or rails that are anchored to the beams or should I just drop the north-facing idea and try to mount parallel to the beams? I also have an ibr roof that is now holier than the Vatican that I need to sort too...
