I am thinking of framing an upcoming house using a roof over. There is one section 24′ wide 9/12 pitch intersecting with a 22′ section 9/12 pitch.
When I “frame over” the 24′ wide section with the 22′ section, where does the California valley start at the first rafter in the 22′ section? Then up the sheathing on the 24′ section?
Do I need a “flying valley rafter” or since they are equal pitches the rafter tails will just but up equal and I will be able to sheathing the 22′ section?
I appreciate any advice you can give.

Bhackford, The bottoms of the valley will meet perfectly.

Warning! Be cautious when taking any advice from me. Although I have a lifetime of framing experience, some of it is viewed as boogerin and not consistent with views of those who prefer to overbuild everything...including their own egos
Additionally, don't take any political advice from me. I'm just a parrot for the Republican talking points. I get all my news from Rush Limbaugh and Fox and Friends (they are funny...try them out)!
So no "flying valley"?...because they are the same pitch?
And the california valley goes from the last rafter on the 22' plate to under the ridge, right. Thanks for your help.
The Valley will go up against the 22' span last rafter sitting up against the top plate of the existing house with the top of the valley planing in with the top of the rafter and where it hits the top of the ridge.
Where they meet at the overhangs is probably what your talking about when you say "Flying Valley". It doesn't matter what the pitches are. If the main house 24' span was a 10/12 pitch and the 22' span was a 6/12 pitch.
What you need to do if you have a level soffit is to run the main rafters with all the overhangs on them first with a solid block where the end of the valley point will meet at the overhang and then your 22' span rafters you can either cut the overhangs off and then just add small blocks with a level cut and a 40° bevel cut for the 10/12 roof or cut your 22' span overhang to sit on top of the 10/12 roof.

I really appreciate the drawings they are great. I hope I can return the favor.
The only part I do not understand is your last sentance. I think I have it down though.
By putting the blocks in it will catch the edge of the plywood and no need to cut special tails or "flying valleys" to go in between.
Thanks again
