Here in the Pacific Northwest any exterior (stairs) wood  rots quickly, so I choose to put my stairways inside.  1000sf for cars, 1000 sf on top, three rooms and full bath.

Their standard contract absolves them of their actions and hangs you out to dry so they can continue providing poor service to tenants and owners.

There are three ways you usually remediate charring.  1) Replace 2) Dry ice blast or 3) Seal (but not with paint)

perform deprecation (most insurance companies require you to do this anyway) Repairing a fence damaged by wind or rotting is generally considered maintenance, not an improvement.

Maybe you have some rotted decking - have you noticed any pooling water with heavy rain?

I had a busted sewer pipe in there, which has been repaired and everything has dried up, and appears to be staying dry.
