Just an FYI but in the new Structural Engineer magazine they have an 
on Engineered lumber in their section tilted Manufacturer's turn and it 
states "Using I-joists in stick built roofs, as a roof rafter attached into 
ridge board, is typically not recommended" It goes on to say that this is 
to the smaller area of I-joists compared to rectangular sections, which 
reduces its capacity in the axial direction.  Another thing to keep in mind 
is that as a members axial load increases, its deflection due to bending 
increases as well.
