How this node works
Where the opaque pitch meets the glazed one, an internal valley gutter collects the water of both. The waterproofing is turned well up each side, and the gutter is sized generously and made inspectable with an outlet, because it carries a lot of water and a blockage floods the building from above. It is the critical detail of the whole roof.
