[USER=21600]@Spectric[/USER] - many thanks for the reply. Interesting, that makes sense although until now I always thoughts the vertical counterbattens were to give the water a path into the gutter rather than ventilation. With your set up, where does the ventilation come from - do you have it at the eaves and ridge? Interestingly, I've asked elsewhere and been told that condensation on the underside of the slates is to be expected and will form just like it does on other surfaces. Much like Jacob says.... [USER=8051]@Jacob[/USER] - thanks to you also for the reply. In my case the sagging felt between rafters doesn't apply as I have sarking boards below the felt. Speaking of which, I'm sure I remember reading that in some set ups the slates are fixed directly to the sarking boards with no battens at all, in which case there would be no air gap and nothing to help dry the condensation? Or would no air gap mean to condensation?
