Post Flashing in Flat Seam Metal

I am looking for advice for flashing 6x6 wood posts that support a balustrade above a flat seam metal roof. The project is the replacement of roofing on an 1870 Victorian Villa. We can remove the balustrade to slip something over the post, or we can fit something on two sides. I can conceptualize that piece. My concern is how to seal the top of the flashing to the wood. Thanks

See the attached drawing for a good way to trim around the post. As for the top, I'm not sure how it ties into the balustrade so its hard to say. You might be able to use a saw and cut a notch into it that the trim could slide into. Again hard to say without seeing it.

I like the detail you attached. I was having a sleeve slipped over the post prior to the balustrade being reinstalled and the cap put on the post. I guess I will have to rely on sealant for the metal-to-wood connection at the top of the flashing. I wish I trusted sealant more.

Oops... Ignore that last post. I think I just realized what you are doing. I had it a little confused. To seal the flashing to the wood, you can either: 1. butt the trim against the post 2. seal around it with tube sealant (butyl preferably) 3. put screws around it to hold it in place or butt the trim against the post cut a notch into the post (maybe 1" or so) install an "L" shaped reglet flashing into the slot and over the trim (see the attached drawing)
