I am planning to use a standing seam metal roof on a new house. The house is very organic and modern, weaving through a densely forested lot. As a result, several sections of the roof curve, not up and down, but like a fan. The issue is similar to putting a metal roof on a round structure–that is, you need pie shaped or tapered panels. Our inspiration can be seen in the attached photo of a palmetto leaf, which is native to this part of South Texas (Houston.)
How is this done? Should we plan to fold the seams on site? What tools are needed? Is there an alternative method, like using CAD machinery in a factory setting?
Thanks for all your help!

Seamer
Perhaps you could rent a seamer.

Never used one so this is not a recommendation nor an ad.
I would think that some larger outfits are set up to take precise measurements and fold everything in the shop, under computer control.
Tapering
If you use the type of metal roofing with loose clips on the leading edge, you can taper the panels and bend up the cut edge to accept the clips. It is pretty tricky to keep it flowing smoothly but the advantage is that you can modify the taper if needed. The completed roof looks pretty awesome!!
