# Roof incidents in Switzerland > Live situation record from CLSTR: https://clstr.news/situations/roof-incidents-in-switzerland > Updated: 2026-08-03T08:20:32.000Z. Sources: 10. Developments: 2. In early August 2026, two separate roof‑related emergencies occurred in Switzerland. On 1 August, a fire broke out on the roof of a terraced house in Schaffhausen; investigators linked the blaze to a defect in the building’s photovoltaic system. The incident caused significant property damage and temporary loss of electricity and gas to nearby buildings, but no injuries were reported. Later that same night, the roof of an uninhabited property on Rorschacher Strasse 189 in St. Gallen collapsed, with early engineering assessments suggesting strong wind as the likely trigger. Emergency services cleared the debris and reopened the street by early Monday, also without injuries. Both events prompted coordinated responses from local police, fire services and technical experts, and investigations into the precise causes continue. These incidents highlight a brief period of roof safety concerns across different Swiss cantons, each prompting swift emergency action and ongoing technical inquiries. ## Timeline ### 2026-08-03: St. Gallen roof collapse on Rorschacher Strasse cleared after wind damage A roof at Rorschacher Strasse 189 in St. Gallen collapsed on 1 Aug 2026, likely due to strong wind.
