Dry hip tiles to wall junction - how should the run be completed ?

[RevNed]

Hi, I have a small rear porch, where the mortar holding the hip tiles has failed.

I have been looking at potentially using a dry hip system instead of replacing the mortar. Although I am not wedded to this idea if its not sensible.

My question is how would you deal with the tiles at the top where the hips meets the wall ?

Any thoughts on this would be appreciated.

Thanks.
