Part of Duquesne University's Mendel Hall roof blew off in strong winds, with no reported injuries.

On March 24, 2025, strong winds blew off part of the roof of Duquesne University's Mendel Hall, with debris falling onto the street. The incident occurred when the sidewalk was empty and no one was inside the building, so no injuries were reported. Mendel Hall was already scheduled for demolition in April, and the university's demolition contractor is now assessing any additional risks before proceeding with removal.
