Dead valley question

Wow.... nice brain teaser. Any more pics..?

How far is it from the top roof to where it meets the lower roof ?

What are the windows for..? Added light to a room ?

What is the turtle for ?

I asked them to get rid of the windows but thats a no go. We are roofing the whole house and replacing the siding in this small area.

I'm not sure what you mean about soldering the top of the saddle? On the left, there are two bends just to get out of the valley. Can I make one bend, cut and overlap the other one, and solder it?

I can make a flat seam to connect two valley pieces and then solder it. Or if I'm good enough, I could buy a roll of copper and make one long piece. I have a 12'6" break.
