Easy to balme the builders however I do wonder whether this is a consequence of having a gap between the top of the cladding and the roof. It would seem that this damage is a result of up-lift force applied to the roof sheets by wind funnelling through this gap. Did the original design that got planning (done by experienced architects BDP) include this gap? It is a strange feature and one which the specified roofing system may not be tried and tested with. Once you start moving into untried areas of design strange things can occur (think of the Millenium Bridge in London).
If this is the same area that suffered damage the other month (I understand it is) then when doing the repair you can be sure that the contractors would have be especially careful to follow installation instructions and not to cut corners. This would lead me to believe that a design or specification error may be the cause.
