How to change "Wrapping at ends" on Roof by extrusion

[espen_faeravaag_da_silva]

Hi! The walls in my project have a very helpful parameter "Wrapping at Ends" under Properties > Type Properties > Construction

I have set this to "exterior" so that my Tyvek vapour barrier will wrap around the wall in a way similar to the real-life installation of the vapour barrier.

I have recently made a roof with the "roof by extrusion" tool and immediately I can see that the interior layer is being applied to the ends of the extrusion, leading to the opposite result I'm looking for as seen in the image above. Unfortunately, there appears to be no option to change this default behaviour like I could with the default wall object.

Any ideas on how to change this? Is there another roof family that will give me this functionality? It's just an aesthetic option but is getting on my nerves... Thanks!

There's no wrapping for roofs. You can apply a Fascia to the edges of the roof.
