I think you have to play with the pitch and rotated angle of the roof plane.

 

But then again, maybe there is a simpler way

sounds like it could work I'm working on a few ways trying to figure it out.  I have to say the responses I receive from this forum is amazingly helpful

Thank you

A warped roof like what you seem to want is either a roof-framers nightmare or his crowning achievement, as it will require tiny pitch changes with each set of rafters, bending sheathing, and more fun things.  Also, it is impossible to draw using Chief roof tools, which only produce flat planar or cylindrical surfaces.

Gene speaks truth. 
 

i would pass on framing that. Without flat roof planes, it won’t be able to be prescriptively designed and wait till you get the bill from a structural engineer. 
 

maybe they could 3-D print it out of a large scale plastic printer and just crane it into place

I appreciate your response and will inform the client

I think the roof is flat, but it is certainly not trivial. I actually did something similar on my attached garage in order to have the roof ridge be below a window at the house. I spoke to the truss guys and they were a little surprised at what I wanted. I describe it to them as reducing the peak of each truss from front to back by 1/2 inch so when I got to the house, it was 3 inches shorter.

Trusses are engineered by their design software.  

 

If this is stick framed with a structural (curved) ridge for a cathedral look..................it's all do-able but the cost just went up.

Not just bending roof plywood or 1x8s, but the interior ceiling surfaces all have to be curved (unless flat ceilings)

 

Crazy fun.  If they have the $$$ and desire.......go for it!

i go down the rabbit hole
