thank you for this forum.
I have a home in Ohio with several buildings. 2 have metal roofs. The house has a standing seam metal roof--half of which I understand was replaced 7 years ago and the other half is approx 20 years old. On the older portion I noted rust around roof vents last year. Why would this be? I thought these roofs don't rust.
Also, Should I be doing something to these roofs--they are in good condition otherwise. No paint or other coating that I can tell. Only the shiny(albeit mildly dulled) aluminum colored surface.
I am very interested because I had considered putting metal roofs on the other buildings and would be less likely to because of the steepness, especially if I have to get up there and wash and paint them as I have seen folks mention on your site. And, before I consulted your site I contacted roofers who will install metal roofs, but each of them tells me something different about maintaince and none of them are willing to paint my roofs, or help me fix the small rusty areas. So, it seems like it will be up to me.
Any advice will be greatly appreciated.

It sounds like your roof was an unpainted steel roof of some sort. I am sure the metal had a metallic coatring of zinc and/or aluminum but that can start to wear this over time or the rust can be coming from cut edges or perhaps certain flashings and washing down the roof from there.
These areas coule be cleaned and painted with a rust inhibiting primer and top coat.
There are more rust-resistant options today with various factory-applied paint and even granular finishes available on various metal roof profiles. These will get substantially more initial life. There are also metal roofs available in rust-free metals such as aluminum, copper, or zinc.
I am also in Ohio. Email direct to me and let me know where you're from and I can perhaps help you with some more of your questions. [email protected]
