Does anyone have illustrations on the correct approach for handling Valley Dormer Terminations when the Standing Seam obstructs clear drainage from the valley to the pan?
I've read of a couple of approaches, but visualizing this is difficult.
A better layout may have helped, but this is my first metal roof, so the learning curve is what it is.
I'm presently half-way through an install on my home - it's going well, but for this issue.
A better layout may have helped avoid this, though not completely - first metal roof, so the learning curve is what it is.
I've attached a photo of one dormer valley termination problem.
Again, I could really use illustrations.
Thanks

Todd,
I did find an older installation of our roofing style in our town with the Valley Dormer Condition.
Their approach to handle the termination was to cut a slit in the roofing panel, and feed the valley through the cut until it extends over the eve edge of the dormer.
I've attached a photo, although I'm not sure if it will upload with sufficient resolution to zoom-in on the detail. I can email you the photo if necessary.
Do you have any thoughts on this approach?
Thanks.

For anyone interested, I found this illustration from ASC Roofing Products showing one way to handle the valley termination when it has to transition over a difficult seam. ASC has a nice downloadable manual that shows a variety of installation conditions for standing seam panels.
See attached.
