Roof Framing Question
Roof Framing Question
(OP)
Any ideas/suggestions as to how this roof could be framed?
Addition going to be installed but at an angle to the existing house so it creates a pie shaped roof that needs to be framed.

how far between the corners of the rectangle at it's furthest point?
I would try to just place roof joists across the gap on the angle, and then you can stick frame a valley set to create whatever roof peak you want.

What is the span and spacing of the trusses?
What is the shape of the exterior wall in the space to be filled?

The exterior wall shape will be as shown on the attached drawing. The truss span will be 32' (16' each side).

Slight modification to my sketch: make the LVL perpendicular to the uppermost girder rather than the knuckle girder. The knuckle girder can rest on the LVL in bearing with an upset vertical plated on to the end of it. That way, you won't have any odd angle truss to truss hanger connections.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

I imagine that your last existing truss is a gable end truss that supported all of the way by a stud wall below. You may be able to just attach to that truss and be done with it as far as the over build goes. Usually those gable end trusses have vertical at 48" that you could fasten a ledger to. I was imagining that you'd need to cut a notch in the gable end truss to run the LVL through and install a stud pack below it.
If you're planning to connect the two diaphragms together for lateral, reconstructing the existing gable end might make sense anyhow just from that perspective.

They call this a skew corner.
