Metal Roof Paint

Copper? Only in my dreams!
I can practiacally guarantee they are aluminum and not steel. I would get some DTM. (direct to metal) it comes in oil or waterborne. Give it a little scuff, and wipe, and put it on. Honestly, I would probably skip the scuff, but its better to just do it. If its rusty (which it shouldnt be) you'll want to nuetralize the rust before paint.
Just a green or maroon scruffy pad to scuff. It doesnt take much. DTM stands for Direct to Metal. No primer required.
Right, I was looking at the SW website for info on DTM and came across a DTM bonding primer, that is why I asked about it.
One roofer suggested tinning paint. Have you ever heard of that?
They make primers for DTM, but its unusual that they be necessary. probably for going on galvanized surfaces or something.
If a roofer suggests something else, look into it. Ive never heard of tinning paint. The only thing Ive come up with on google is about soldering... It might be for raw metal or raw tin.. Just because roofers use it, doesnt necessarily mean its better... Maybe it is though, idk. Ive done a lot of exterior repaints, and Ive never seen factory painted metal on a roof that was in good shape. I'd personally trust DTM over what Ive seen them painted with. Youre also not going on raw tin, your going on top of an existing paint layer.
DTM WILL work though, if you cant find this stuff.

If they were previously painted you do not need direct to metal paint. You are not painting direct to metal, you are painting over paint.
The tops look like paint is gone, at least on quite a few of them.
