Red/brown streaked stains on vinyl siding

We have a park model home with 3 season Rm attached. It is in a seasonal camp ground. All of sudden this Sept. we started to notice on our porch which has an aluminum 3 season roof over hang there is reddish brown streaks on the vinyl siding and also the aluminum storm door. What can cause this?

Hard telling since we can't see it. My first guess would be decaying leaf trash on the roof or in the gutter.

Could be from not using galvanized nails.
Sounds like rust streaks.

WishI had taken pictures before I washed it off. If streaks come back will definitely take pictures.
Thank You

Took it off with some Lysol wipes, was relatively easy to wipe off. Just took this now. Wasn’t there earlier. Nice day out no rain. Post is at edge of porch roof over hang.

Your pic link didn't work, try this - https://www.doityourself.com/forum/e...-pictures.html

Since it was easily removed it either hadn't been there long or isn't too bad of a stain.

Quite possibly decayed leaves. Check/clean your gutter/roof.
