Working with the tin on the roof wasn’t as bad as all that. I can say that now that I’m done and back on the ground. You become hyper-aware of the weather when balanced on strapping 16 feet off the deck while handling broad sheets of sharp tin. They make decent sails and a pretty good toboggan, too. I cut my hand on an edge while it was spitting rain and deep red rivulets of blood went trickling down the bright silver of the metal roof. (It would have made a nice cinematic detail shot, like in a Terrence Malik movie.) In my pole construction cabin, the tin roof is likely the only place where the components fit squarely together. Which they did, thankfully.
