Roofing in Kleine Kuppe
Kleine Kuppe is largely modern construction, and modern construction here means flat concrete roofs behind parapets. That changes what can go wrong entirely: there is no pitch to save you and no gutter to overflow harmlessly.
On these roofs, the waterproofing system and the way it turns up at the edges is the roof. Everything else is structure.

What actually goes wrong in Kleine Kuppe
Parapet upstands
The membrane must run up the parapet to a proper height and terminate into a chase or beneath a capping. Where it was simply stuck to the plaster face, it peels and the leak shows along one wall.
Ponding and outlets
Where the fall is flat or reversed, water stands. Standing water finds pinholes and shortens membrane life dramatically. Undersized or blocked outlets have the same effect during a heavy storm.
UV on exposed membrane
Unprotected membrane at this altitude ages faster than the datasheet suggests. Reflective protection is part of the specification, not a finishing touch.
Complex penetrations
Solar mountings, geyser pipes and air-conditioning feet all puncture the roof. Each one needs a collar detail; most flat-roof leaks in newer builds start at one.
