SE needed?

What is supporting those steel posts? Are there footings under the slab below each post or are the loads carried only by the concrete slab? (It looks like a former concrete patio to me.)

Did you probe the steel posts to see if the rust has damaged the structural integrity of the posts?

Look at the lower right photo which shows the Front Right Post with the tree in the background - see how much that bows out?

I think the first order of business would be to have a contractor open things up ... *then* call in the SE.

I'm guessing that the Left Rear Post goes down to a footing through the porch slab, it also looks to have been repaired once before. The rusting is breaking the concrete out around the post.

I suspect that bulge at the top of the Front Right Post is from rust - and that much rust is not a good thing.
