Jim McGuinness said during an emergency meeting that he was on the roof to inspect work of replacing roof anchors, used by window cleaners to attach their equipment, the Palm Beach Post reported. Hours after his inspection of the roof at Champlain Towers South, at around 1:30 a.m. Thursday, one leg of the L-shaped 12-story tower pancaked, killing at least four people and leaving at least 159 unaccounted for. Rescuers have had little luck combing through the pile for survivors, and no one has been found alive since Thursday morning. “There was no inordinate amount of equipment or materials or anything on that roof that caught my building official’s eye that would make it alarming as to this place collapsing,” McGunniess said during the meeting Friday afternoon.
