I have always lapped parapet cap flashing the same way I do metal ridge caps, sealing between the layers with several beads of Big Stretch. Lately, I see more builders are using a standing seam at the joints. Does anyone have a detail of how this is done?
Thanks.

I'm trying to picture where a parrapet wall would use ridge caps and flashing together...

Sorry, I meant to say that I lap parapet cap flashing the same way I do metal ridge caps... I'll edit my original post.
I just can't figure out how you would bend the ends of the pieces to get a waterproof standing seam. But looking around, everyone suddenly seems to be doing it that way.

OK, I see what you mean.
I've done both ways - one is the 6-8" lap with caulk to form a sort of compression gasket in place.
The other uses a returned hem on the cap and a joint piece like they use for duct workslid into place and locked down

Ah, you are right. That's why they look so uniform. I was hoping it was something I could do on site. Thanks.
