Join sloped roof to flat roof

[rdifilippi]

How do I connect top to bottom these 2 roofs.

The structural is sloped but the insulation w/ cricket cannot be sloped.

1. Structure is a sloped roof or floor.
2. Insulation + cricket is a flat roof with modified sub elements.
3. Join geometry, select Structure 1st.
