It needs weathering over two courses of tiles. If he went under then protection would stop at the first batten he hits.Lead apron should be underneath the tiles.

It's not the easiest to deal with due to the fragile cuts and the way the cuts sit at the top of the GRP valleys. What he has done is correct in terms of weathering. There is no easy way of saddling the valley junction whilst dressing neatly over fragile tiles. We always dress our lead away from the junction on a dedicated mock-up so that we damage sacrificial tiles rather than the real thing.Just a very scruffy finish.
Under the ridge. You treat the lead as a tile.The lead saddle should go over the ridge tile as shown on the guide to rolled lead detail .
