Custom metal trough

From the outlet of the shallow valley (where I've now installed a standard metal valley flashing because the whole area will have metal tiles), there's a sharp right turn to get into the gutter. It required a special piece of sheet metal.

The easiest and best way to make this custom trough was to mock up the final aggregate shape using cardboard and tape. The mockup only helps to show how and where the sheet metal should be cut and bent. I decided the best width was something that matches the nearby gutter. It'll line up the edge of the metal roof tiles with the front of the gutter.

With this piece finally fabricated and installed, my biggest worry is now behind me. Rainwater will flow over the metal tiles into the valley flashing, then into this trough, then into the gutter, with the Grace underlayment as secondary measure. The metal tiles on either side just needs to be bent over into the trough.

See earlier post showing how the incompetent roofer did it.
