Outbuilding Roofline

[Wesley_C]

Hi,
Builders who done my roof for outbuilding a while left it without any fascia/guttering etc. I'm planning on using 10mm barge boards flat with dry verge interlocking caps on the sides and 18mm fascia on the front/eave. I am stuck on how to tackle the rear of the roof as its just overhanging tile with batten along the side.

I attach some pics to clarify,

Any advice much appreciated
