Stairstep or Straightcut

When re-flashing a chimney which method do you feel is the all around best way?

Stair only. No need to ruin the brick.

Old School Said: Twill, I have done them that way, but I would put a hem on the bottom of the flashing, and then kick it out at a 45 degree angle. I would also keep the bottom about a half inch above the shingles, and make sure that the step flashings are slightly exposed. (dont run your shingles tight against the wall. It lets the water run freely right off the roof.

On the other hand, whatever works!

I always run my shingles tight against flashing/walls. To be honest, I don't use counter flashing either. Strictly continuous. Then again, every place I install flashing the shingles are cemented to the flashing. I spent a lot of time in snowy/icy conditions, & have seen ice migrate under step flashing installed in the manner you describe. Have never had ice work under shingles/flashing the way I do it.

The stairstep is traditional. Dudes did not have diamond blades on their grinders 300 yrs. ago.

Same here. I remember years ago making cuts with a skill saw (diamond blade). Wow. things changed dramatically when I got a grinder :) Pretty easy to do. I've done some steps but, I like the way a continuous piece looks.

Here's one I did recently. This one was a no brainer as the previous roofer had already cut into the brick.

Not a fan of cutting into the brick, so we stick with the classic stair step. When done correctly, I can't imagine that either method would cause an issue.
