Repairing a Chimney (The upper part of the chimney demolition TIMELAPS) сломал верхнюю

I checked the chimney and found broken spots at the top of the chimney. I build around chimney wooden scaffolding. Working on the roof is #dangerous and takes a long time(time consuming). I used wood and screws. I tightened the screws with a cordless drill. I broke open the chimney with a large hammer and chisel. #ErgoThingdid
