Flashing detail for low slope tie in

Hello, New 4/12 standing seam, transitioning to existing low slope (1/2:12), double layer, self adhered roll roofing. I see it's a common question, but I'm confused on the preferred method to install the underlayment and flashing. Is it best to have the flashing over the P&S like a valley or P&S over the flashing (drawing attached)? Thanks, any suggestions appreciated.

Are you doing this roof? Why not run mechanical standing seam on the low slope section? Either way, I prefer to run the low slope up the section with greater slope. Put your peal and stick over that transition and have you underlayment go over that. Have a bit longer starter piece that extends over the low slope section and acts as a bit of a valley (if I were doing it).

Yes, I'll be the muscle. And why not redo the low slope now? Because it's in good shape and I'm cheap. Please confirm my interpretation: flashing applied over the underlayment and extended out onto the low slope for 3 or 4 inches (picture attached), Thanks		Merrick Endres 10/3/2016	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21553/find/
Looks good. I would just make sure the transition flashing isn't super tight so that water can drain out freely.		Eric Novotny An informed customer is the Best Customer! 10/3/2016	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21554/find/
