Vinyl siding detail at projected angled wall
So I am going back to vinyl siding on this single family house due to cost reasons. I have this projected angled wall shown in attached image and would like to know if this siding detail works well. Because of angle, some water might go behind siding, but there is tyvek behind so it will dry out. Is this fine or do you recommend a different WRB for this. And is there a better way to finish that corner of wall? I just put 2 standard corner trims and siding in between.
2nd question is about the metal coping to top of that wall. I have usually not seen that over vinyl siding but is there any better way than this? And can anyone suggest for a detail where the metal coping meets the vinyl corner post trims at the top left corner?
Appreciate all your help.
