Hi

I am looking to built a Pod from scratch gothic arch and was wondering were the metal tiles meet the barge board / facia if there is a flashing or not.  Or it does not mater due to the overhang being out side?

 

I cannot see whether the wooden arch oversails by much, but if I were making it up from scratch I'd perhaps make the arch say 50-70mm oversize all round, build in L-shaped 'end soakers' as you roof, (maybe v thin alu - at one time - when I had a supply - I'd have used second-hand printing plates) then sandwich one leg of the soaker between the arch and a rear-face 'mini-arch'. I wish I could draw! Not 100% sure what you do at the top, but I am sure the solution would come to me when I got there!
