best way to do dry hip

hi guys. I put a pitched roof with a hip on my mum and dads extension but it has 2 different pitches as it was an awkward shape and my mum wanted the roof to look nice lol one side is 15 degress the other is 23 degress.the roof has been tiled using Redland grovebury.

I would like to use the Redland dry hip system but im unsure if the hip tiles will work due to the different pitches. Im not a roofer but a plumber and done this to save them some cash. any help would be much appreciated

anyone have any advice please

orr come on lads, I really really appreciate some advice of someone who knows what they are doing. Really want to get this roof finished before the harsh weather rolls in

please help

I don't think it will make any difference and there are installation clips on you tube to watch.
