I agree with the idea of running the tie right out. Will be stronger and less work. A couple thing to consider depending on your inclosure system and your location:

1. It will be harder to close the structure with a changing roof pitch

2. depending on how far north you are the part of the roof that is not seated directly on the house (overhang up to where the pitch changes) will be cooler than the rest of the roof. This can cause icing and a leaky roof. The ice forms on the overhang and slowly pushes the shigles up.... you will need to use ice guard.

Where is Charlestowne? I believe you said you were in the huricaine belt... so this won't apply..... but strength of the overhang sure will!!

P.S. Does look rather quebecois, however their pitch change is more of a curve...
