A picture would do wonders for getting answers to your question. Usually step flashing followed by counter flashing...........but, every chimney is different & some require special work to properly flash them.

kskier,

It depends on the type of chimney and roofing being installed. Here is a site with different chimney flashing examples.

And some links to the best videos for chimney flashing

As you can see, there are many styles. The critical areas are the corners. Like the 60 year old galvanized in the link, I much prefer the ole style with tinner's wings on the corners. The style dates back centuries before caulk was commonplace. No reliance on caulk or solder as the metal hides the corner detail from windblown rain and snow. It's ideal for rookies and your work can be less precise.
The devil is in the details. Step flashing needs to be bent less than 90 degrees and pushed into place. The steps must lap each other correctly. The corners must be protected.
The termination flashing on the first piece across the front of the chimney must be cut so it's 1/8" wider than the chimney to ensure a tight fit when that first step flashing rounds the corner. No gaps that way.

I’m no roofer, although I’ve done plenty of roofs and flashed plenty of chimneys and none of them looked like that.

I will say I’ve never had the pleasure of terminating rolled roofing into a chimney before so I’ll reserve my comments and let the big guns weigh in.

Where it is a chimney on the perimeter of the roof there`s nothing wrong with that method.

im looking at using flashing and forming a skirt at the outer area >its a 1 piece form for going across outer lowest point of chimney.Is this a good option with metal roofing?
I was looking at cutting grooves in flashing for water flow onto the wavy curves of roofing.Joining onto original flashing on sides with skirt 3 inches on sides.
