Wonder if you’d recommend I extend the shingles back under this overhang (it’s about 12″ deep), or terminate them away from it? Any other advice on this little bugger of a corner also gladly accepted.
Thanks.

...from an aesthetic standpoint, yeah, that would be nice. I'd hate to punch any more holes in that beautiful membrane than necessary, but as it looks now, if a lotta water washes down that valley, its going to go under the first three courses where they terminate. So I don't see how you can avoid it. Interesting to see what anybody else thinks.
No problem with aesthetics--can't see it from the ground, unless you're WAY out in my field. ;-)Since I can't get under most of the overhang, to nail, I'm guessing you nail where you can and leave the inaccessable parts 'free' (the way they were, pre- membrane)?Thanks.
I don't think shingling under that overhang would be a good idea as long as the EPDM is well installed under there. The reason I say is if you build that up under there then the water will wind up rotting and/or entering the overhang so leaving space for it to freely flow is probably your best bet. Also, if you were to cut those three courses as though they were a valley, then the upper valley could shed it's water over a wider area across the EPDM roof.
Just my 2 cents
Tab,
I doubt very much if I would have ever put those bottom three courses on in the first place.
since they are there now I would probably cut them back at an angle like a valley as already suggested. I would use a hook knife----probably safer for you to use an old pair of tin snips working so close to the rubber.
My BIG concern is exactly where your nails are now------on at least that bottom course I probably would NOT have put them in the standard placement-------- I would have possibly high nailed and bedded the shingles in some water cut-off or most likely geocel.
If that membrane is fully adhered and for some reason you really were determined to extend those 3 un-needed courses----you could glue the few remaining shingles in place with geocel----probably wouldn't hurt if the membrane is fully adhered---but I still wouldn't reccomend it.

Stephen, the reason I made the post I did was because I don't know how far the EPDM goes under the shingles.
Dustin,
I suspect we are thinking along very similar lines.

Where the fascia and cornice molding run back to hit the other roof plane under the valley - I can't see how the EPDM is detailed there. It looks like it is just a notch cut flap laying rolled up an inch.
If so, I would try to remove or at least loosen the cornice mold at that junction to fit a piece of step mold undr it and over the facia, laying down over the EPDM a few inches. Retack the cornice.
Then I would leave the first course of shingle as is, and run the next two over to the step flash piec, and tucked under the metal valley. Hold the nails high so as to not be poking too many low holes in the membrane.

If I understand you correctly, the step flashing will be in effect 'hiding' the intersection of the cornice mold and the other roof plane? And if that's correct, I'd like the step flashing to be wide enough to extend from under the metal valley to about the bottom of where the second row of shingles will end?Many thanks to all, for the advice.

Got it.
Thanks again.
