Valley rafter intersecting trusses

[Bammer25]

Doing an addition. Existing house has roof trusses. I completed the design while my mind was in stick build mode. There are a couple valleys that I designed as LVLs from the new portion of the house that will break through existing trusses.

Is there a standard connection you guys use? I figured add a vertical chord at the break at a minimum. Sheath off a few feet? I also thought I could run the valley and then stick build back what had to be cut?

I will add none of the ceilings are vaulted. Now I am second guessing my whole valley approach. Would it be better to simply overfill?

If the ceiling stays flat it's almost always a lot easier to over frame.

Agreed. Just overbuild on the existing trusses. I reached out to a truss supplier one time about the added dead load from the overbuild framing and was told that it's pretty negligible so they don't specifically account for additional dead load in those scenarios.

Another vote for over-framing.
