Hi
Any thoughts or comments about how the tiles here have been laid in the image below. I have seen many images and demo videos about laying a slate roof and none off them look like this with the slates having gaps between them, as opposed to being flat on one another right from the start/eaves course. It looks to me as if the outer brick skin is one course too high and that to compensate, the slates are laid with gradually changes pitch? Also as it will be a cold roof, I don't see how it can ventilate if the eaves tiles sit flush to the brick.
Thanks for any advice you can give.
Mark
