I have this:

I need to attach it vertically to some thick hard rubber roofing. There is a small section of roof which should probably normally have a parapit but instead the roofing rubber is not backed by anything. Then below it is a wood panel. So when it rains sideways the water runs down the roofing rubber and behind the wood panel.
I just need a piece of shingle to divert water to the exterior side of the panel. Roofing glues are made to never cure. Probably rightfully so, but that probably wouldn’t work to attach a shingle vertically as gravity would over power that tar-like never fully dry stuff. I tried construction adhesive & it didn’t hold.
For near-vertical mansard roof shingles, I think they use a combination of lots of nails and plastic cement.
Thanks for the suggestion but in my case there is nothing to nail to. A shingle must be attached to thick (~2mm) rubber that’s just formed to be vertical. Perhaps I need to rivet the two rubber pieces together. Or I might try construction glue again but also get a couple metal plates and screws to clamp them together as a permanent clamp.
This is a use case for a step flashing or pan. Use sheet metal cut to shape and bent at a right ( or other angle) to give you a nailing surface. You nail it to the roof deck and it stands up.
