I don't think it would have been possible to do the roof first for this project. Even if it was possible, it wouldn't have been easy. This was a three story build.

That's exactly how I did my three story build. Core wood poles and beams, temp ladders to reach the top, put my smoke holes and roof tops on and built from the bottom up after that.

Core wood poles let yo go up to a max of 24m. I went up 12m for 3 stories with an extra 4m for my chimney caps. It rained 4 times while I was building the frame and only had to repair the core wood poles and beams that weren't under cover. The ladders I didn't worry about. They were getting removed when I was done.

If you mean 3 full stories with sloped roofs on top for a 4th floor attic and chimney caps you can still do that with core wood poles. Wood iron poles let you go up 50m.
