   How does the step flashing get "finished" at the ridge?

   I guess that could be interpreted different ways.

   How do you finish the step flashing at the top of the raked section? By trimming that last piece of flashing at an angle that will be hidden under the hip-cap shingles. Or you could just bend it over the hip and cover it with the cap.

   Or

   How do you flash the horizontal wall-to-roof joint? And L-shaped piece of flashing, as long as the joint; run up under the siding, and over the shingles. If you don't like the look of exposed flashing laying on top of the roof, then cover it with additional shingles.

   Or

   How do you get both of those two types of flashing to meet properly? Run the rakes first, as you are shingling your way up the roof. Cut or bend that last one. Then shingle the center all the way to the top. Put that flashing in so that it is over the last of the rake step flashing. Then put on the decorative shingles that hide the horizontal flashing. And finally, the cap shingles on the hips.

   Unless you're the lead dog, the view just never changes.

   Where a hip (or ridge) hits the vertical wall I typically step flash both sides up to that point. Then I apply a couple pieces of peel and stick waterproof shingle membrane to seal the connection. I use pieces about 12" square, fold the membrane against the wall (6" up) and wrap the top of the roof connection about 1/3 of over the ridge and the rest over the shingles. I snap lines to guide cap shingle installation and trim the excess membrane to the line. Then run the cap shingles from the bottom (in case of hips) or opposite ridge end so they end at the wall. I use another piece of waterproof shingle underlayment to seal the wall to the final cap piece. Finally I cap over the membrane (and cap beneath) with a piece of lead flashing. Lead is easy to fold and hammer form to the connection. Sometimes a slit half way down on the wall side helps on steep pitch roofs - If I make a slit I put another piece of underlayment membrane to cap the joint. The siding covers the membrane so it won't be exposed.

   I'm pretty satisfied with the connection seeing as how it has 3 separate layers of protection. Overkill? Yes. Leaks? Never.

   On the last piece of step flashing from either side, cut from the top  down the fold an inch or two. Install the first piece and fold the roof side of the flashing over the opposite slope. Do the same thing with the other side, except slide the verticle leg of the flashing behind the the 1st one you installed and push it in until the end of the two slits are tight against one another. A picture would be worth a thousand words here.

   get a piece of lead and form it over the ridge and up the wall so that it covers the top step flashing on both sides of the ridge...

   I do what Mike does.

   I use a cpl of layers water and ice shield over the ridge up against the vertical wall/rake.

   Simply just bending one piece of the flashing over the peak would work just fine too IMO but I always have Water and ice shield around so what the hell, its easy enough.

   Be well
