So, that is not how we did it. Instead, I came up with a plan to add a vaulted ceiling in the tear to take the normal 2” thick, flat, roof and reduce it to under an inch thick and bowed. A lot of head scratching and more then a little bit of trial and error led to the result that you see in the picture. So far, the inside looks good, but I can just bet that I will have “issues” trying to get the roof to match the new curves. I guess I will just mark this up as a lesson learned for teardrop number two. Umm, not that there will be a number two, of course. (my wife may read this post) But if there was, I would do a few things differently.
