St. Gallen roof collapse on Rorschacher Strasse cleared after wind damage

On the night of Saturday, 1 August 2026, the roof of an uninhabited property at Rorschacher Strasse 189 in St. Gallen collapsed. An external structural engineer’s early assessment suggests strong wind may have caused the failure, though investigations continue.

A coordinated response involving the city police, the external engineer and demolition specialists cleared the debris. The street was reopened to traffic shortly after 1 a.m. on Monday, with no injuries reported.

The priority remains the safe removal of the remaining roof structure and a full investigation into the exact cause of the collapse.
