Erik, This most definitely is not a typical valley completion. I would be curious to know exactly how it was done. There may be unseen parts that make it not as bad as it appears. But, right off hand, I share your concerns.

Erik,
Petersen / Pac-Clad knows the detail for a proper valley. I realized they only provided the coil but they are good people and should be willing to help sort this out with the contractor if you contact them.

Hello, I am a homeowner and I am having a standing seam roof installed on my porch by a local sheet metal contractor. The worker who has been doing the work has told me he has finished and I am concerned about the valley flashing. A section of valley flashing is installed underneath the standing seam panels and then is bent up and over the bottom of the panel (pics: https://picasaweb.google.com/104088445589120867537/Valley#). The bend is pretty rough and leaves small gaps between the flashing and the top surface of the panel.
My concern is that water, ice, snow, leaves, etc. will get caught on this edge, and most certainly in the gaps, and will cause future issue with backups. I am also wondering if some of the water that is caught in this channel won't migrate back up underneath the panels. Am I missing something here? I thought the idea of the roof was to shed the water, ice, etc. as quickly and easily as possible, while protecting everything underneath.
I have asked the boss to meet me and go over the issue, but would like to know if I am right to question this or if I am just misunderstanding something about how this system works.
Thanks. Erik

Thanks for the replys. I have spoken to the contractor. He explained that this detail was to protect the panels in high winds. I countered that many of the systems I have seen online are warranted for very high wind conditions (UL 580, etc.) and wondered why this detail was necessary. I also asked what system they were using so I could check the manufacturers warranty and suggested valley details. He said they buy the coil stock from PAC-CLAD but make the panels themselves, and only guarantee 5 years on labor and materials.
This is not a 'fly-by-night' company mind you. They have been around for over 100 years and are listed as an approved contractor on SMACNA's website. They offered to come back to try to flatten the seams some more so it didn't look so bad and then caulk it so it didn't hold ice, snow, debris. I said that would not be acceptable unless they could prove to me that this was "industry standard".
I have not heard back in over a week and am ready to 'fire' them and move on. Although now I am skeptical of finding a competent contractor. All indications were that these guys should have been able to easily handle this small job and this is what I got.

Wow.
I must say that is a first. If the caulk application is any indication of his skill, I would be concerned.
