Roofers accidentally set the roof on fire during their work, which led to serious access issues. The situation made it difficult for emergency responders to enter the building and check whether the fire had spread through the roof. Firefighters had to use a tower ladder from the Chicago Fire Department to get a better view and assess the damage. The incident raised concerns about safety procedures on construction sites, especially when working on or near roofs.
