Gable Over front Door

[braido11]

Thanks, that clarifies things greatly. I think that the issue was that I was trying to create a gable roof over the front entrance door, but the second floor above it was just a flat wall (see picture). It looks like I cannot use this function as I thought.

As you suggested, should I try to put an invisible set of walls from the second floor that I can put a roof on. Or can I buld a roof over the front steps with some type of deck feature?

Thanks!
