Hello everyone!
So far, I've managed to navigate around most of the problems I've encountered while working on my construction. But now it's right into the wall. Bang! I have no idea how to proceed.
The valleys look like my sketch. A U with wings.
The two meet at the ridge, and it must be watertight. Metalwork is not my strong suit.
How do you join/splice two such valleys to make it watertight?
Or is it just time to admit that I need to call in the professionals here??
