I have an attic full of leaky lawsuit pipe, knocking out a repipe with PEX this week. Any reason to remove the old iron pipe besides the few pieces necessary to patch in?  Using the stainless clamp method to connect the PEX.

Most plumbers leave it in the attic and walls after a repipe.
No reason to waste time removing it.

Sounds like a bunch of target stand material you're not taking advantage of.

In the PNW I can't recall plumbing above head except for fire lines... is this a thing in your area?

Here in the gulf coast a lot of homes have water heaters in the attic and the supply feeds into the floors of the attic, then down to fixtures. It will suck when my water heater goes out.  Its in the second story attic too.

They don’t even have basements down south

Things that are done in the north everywhere aren’t necessarily done where it doesn’t freeze

This, it's good pipe, pull it and use it and then you don't have to worry about it being in the way of future work.

My house had gas lines plumbed to some fireplaces and such. Previous owner tore out the fireplaces and owner previous to hill took the tank with them when they moved. Pipe sat exposed for years, who knows what junk was in it. Every time I go in the crawlspace to check something I take a pipe wrench and pull some out and bring it out with me.

Not removing old material after any renovation is a combination of poor craftsmanship and laziness.

To a certain extent yes. If you have to do additional demo to get to it then leave it there, but remove what you can get to.

When I redid the plumbing I removed all the old pipe.  I had a basement to work in and it was easy to do.
Hack saw and a sawz all  made it really easy to remove the stuff.

We have water lines in our attic. Newer 2018 build. All of our ducting is overhead as well.

Like to remove any unnecessary weight from the roof trusses. And makes for cleaner refits.

I have a great sawzall .  The vertical runs will have to stay but will likely remove all the attic pipe.  It was nice to have it to stand on when working up there but I'll be adding some decking anyway.  I plan on selling it next year so doing the cost/benefit analysis on everything..  good thing I bought most of my PEX supplies for this project, appears it's going to be hard to come by for a few months with all the broken pipes from winterpocalypse.  Another member in my area posted he was having a difficult time sourcing 3/4" PEX and crimp rings. I may be a little short with 20 3/4" crimp clamps and 30 1/2". I should have just bought rolls of pipe. Was running red/blue and then couldn't get any more red 1/2 and 1/4 in 10 or 20' sections so I picked up white. I'll just sharpie it "hot."

You can see where leaks have self sealed all along the pipe seam (hence the lawsuits)..

Our interesting construction methods in the South.. Will be significantly cleaning up the routing of water heater supply and output lines.

Unless it is on the way there is no real reason to bother.

Same with abandoned electrical.
