How far does the EPDM have to go up against the joining pitches tiled roof.

I suspect 2 tiles. If this is correct do I remove the 2 roof battens and replace when the EPDM is fitted.

300mm and on boarding, and lap the sarking over it

If you are refixing the bottom tile batten onto the board, then to need to allow for drainage with some notches

I've never used sarkings. What would you recommend and tips diagrams.

That should have been sarking felt, ie the pitched roof felt or membrane. Some notches in the bottom of the batten normally does the trick
1. What size would a cocking fillet need to be ?

2. I have plenty of spare OSB 3 off cuts. Could this be used for layer board under the tiles, instead of plywood?
OSB will do, but be sure to fix it flush with the rafter surface not on top of them. Nail some lathes to the rafter sides to support it

The fillet can be about 25mm (a tile batten) but it will need to support the tile at the correct angle
You've got another week of fine weather :cool:

3.6mm might to ott thin unless you put supports beneath. 6mm should be OK
Does a roof cocking fillet need to be triangler, or would a simple roof type batten would do the job. This fillet would need Kick out my redland eave tile, 165mm x 200mm.
