The question is . . . "When do you want your valleys to leak?"
If your answer is "Never.", then how do you plan to make that happen?

If you repair slate roofs, then you are too familar with leaking valley pans.
They are often rusty, pin holed, in need of paint and walked on by uneducated tradesmen.
Copper is a fine solution, but quite soft and too easily torn or penetrated over time.
Any material you can purchase in a roll, is just too thin to withstand the tests of time.
We designed a new solution for our client and have posted some actual jobsite photos below.
It was a difficult access location, and our goal was for the valley metal to outlast the slate.
The pans below were designed to meet NSA (National Slate Association) standards.
They are 48" long, interlocking with an 8" overlap and nailed at the top only to allow for 1/4" expansion per piece.
However, we used 22 gauge stainless steel (practically impossible to drive a nail through) and copper plated the exposed portions.
The stainless is .03" thick, laser burned in a Virginian ISO9001 facility and preformed for ease of field adapting.
