Hello,
I have a client who wants a low profile standing seam metal roof.
The roof is a 4′-12′ shed. We are doing drip edge on the eaves and low side. For the high side peak can we do a d-style drip edge, with the roof metal bent over the drip edge as normal?
Anyone foresee any problems with this?
Thanks!

Greetings,
I’m at a loss at understanding.
I have a client who wants a low profile standing seam metal roof.
The roof is a 4′-12′ SHED. We are doing drip edge on the eaves and low side. For the high side PEAK can we do a d-style drip edge, with the roof metal BENT OVER the drip edge as normal?
Is the bldg a shed or is the roof a “shed roof”?
Which might “shed” light on the PEAK. Please explain the BENT OVER part.
Sorry if my simple mind didn’t get it and hope you get a good answer.
Having worked in the commercial end of metal roofing, I’m not understanding either. You don’t bend the metal panels, they lay flat to the roof deck and on top of the eave flashing with the 30 lb felt under it all since it’s residential. The drip edge is fastened with a cleat to the fascia.
Are you talking about a saltbox roof style?
Thanks for your help @calvin and @Obeeswax -- I attached a drawing for clarification.
The house has a shed-style roof.
"Bent over" meaning the metal panel bent over the d-style drip edge (as one would normally do at the eave).
My question is -- can we do this at the high peak of the shed roof? Or is there risk of water getting in there somehow?
Thank you.
It might work fine for the bulk of the width of the panel, but there's no way to bend over and thereby seal the standing seams. So every 16" or so you've got a penetration point and water entering the top and running down under the panels. The typical residential detail I have seen (and the kind I used on my own install), required z-channel screwed at the top, on top of butyl tape, caulked with Tremco up the side of the standing seams at each end, and then a cap riveted on that went down the backside and clipped on a cleat: (Like this detail, which was the system I installed from Union Corrugating):
@Mikeljon -- thanks! Yea that makes total sense. I've seen the photo you've attached as well with the z-channel. I didn't think through that the standing seams wouldn't be closed up. That's why this forum is here!
Thanks again for your help.
And if you omit the z channel between each standing seam, you'll get wind-driven rain upwards and under the top flashing. It's a PITA to do each of those (I had 55' of a peak to do, so that's a lot of sections), but got in a groove and got them done and had no leaks.
