These cantilevered roof sections have in some instances collapsed beneath and fallen upon firefighters working at incidents. Never assume that they are as stable as the rest of the roof appears to be, since we probably will know neither the condition of the fasteners and connections, nor the condition of the structural members, nor the effects of fire in the concealed space upon both the connections and structural members.
