Roof Battens visable after new tiles laid.

Thanks for the feedback so far, this one might shed some light, see the purple line i drew to the part that was concerning me, I can see the soakers installed along the chimney breast.

The main culprit is the cut tile beneath the first full tile behind and up the roof from the back gutter.

Whilst the back of the chimney is tatty, its probably weathering ok. I'd be more alarmed at the lack of soakers.

I suspect they might of used those ali soakers you can now get.
