   I'm not a roofer, but the roofs I've framed like this the shingler usually had to taper both sides of each shingle. The further up the cone you get, the more you taper. Takes a few more shingles that an equal area regular roof.

   I've seen guys run them perpindicular to the fascia but I think that looks funky and question it's long term capabilities.

   You can also frame an octagon and simplify things.

   So, the bootom of the shingles stay straight and you just taper the edges?

   I'm not the last word on this, but I would imagine as you go up the cone, the shingles edges get closer. Like going from a three tab w/tapers at the bottome course to a 1 tab w/tapers towards the top.Lots of waste.I saw one guy try and get replaced because he was overlapping instead of cutting the edges. Looked terrible.The one time I saw them ran askew I looked and had to take a second look. It was pretty creative. It looked funky like a DNA strand. Triangles and circles work. Rectangles and circles don't.

   Look for a response from SeeYou.  I've addressed this to him, so he'll find it. 

   He's the copper roof expert here, and can advise on the metal soffit.  Perhaps he can make you a nice copper cone for the very top, too.  Have a look at his web site:

   The last "witches hat" we did in shingles, I did. Once ya get the hang of it, it ain't to bad. But like Piffin says, lots of cutting and waste, and I'd HATE to do it with 3 tabs, dimensionals are forgiving.

   To the OP, I'd segment the soffit with 3/8th ply wood arcs.

   But of course you absolutely gotta do something special up on that pointy top -- a decorative finial or weathervane.  I love that picture on the right on Grant's web page.

   I framed one four years ago with a 21/12 pitch and the roofer made his own copper shingles. Very different and intersting looking. Here's the link with pictures.
