i noticed that you didnt use any breathable felt eitherYup - it was thin tongue-and-groove on the roof so I put 18mm OSB on top of that and screwed the tiles to it using the onduline screws
as i would have fitted some of that first
better to have 2 protection coats instead of just one
and you can also use guttering with it as well
