Situation – 1940’s house with garage butting gable end. Garage roof is 12×16 slate on a 12:12 pitch with about 6.5″ exposure. Step flashing to be installed is 8×10 (4x4x10). I know HOW to install the flashing but is there a “best” location with respect to the overlaying slate? I was thinking about simply locating each piece of step flashing such that it was centered underneath the overlaying slate.
Thanks in Advance,
Eric S.

Eric, I doubt "centering" the step will be best.
the way we do it---and the way we have always seen it done -----is to position the bottom edge of the step barely in line with the bottom edge of the slate or shingle----in your case that means the step will run under the 6.5" exposure and allow a 3.5" headlap
Thanks.
I did as you suggested and all worked out just fine.
