@michaelk Haha- no worries. There are two sections of roof- one is a true spiral, and the other has the level of the eaves uniform around while the top spirals up. The pitch is 18.43, the entire rise of the roof is 25'. The top part goes along a spiral that has a starting radius of 40' and ends at 10', making 1.5 turns. It will theoretically be constructed with tiles––or will be a metal roof, that part is still TBD. Let me know if there's any more info I can provide, thanks!
