Hello all, new here, and I have some rot from a deck my dad built in 89 (ledger deck issues).
I recently bought this farm (term only), and as I was tearing old decking, I also had to take off the ledger deck. I have about a 12-16″ section of rot and bowed rimjoist, and 5 pieces of car decking rotted (only the ends at 4″ or so).
Joists are parallel to rim joist. Here is the pic. The structure (old part of house) is a 1963 aframe w/full loft.
The issue gets better though. My grandfather built it, and used fiberboard over the car decking (I’ve known this many years).
First pic is area of concern.
Second is perspective.
I’m curious if I can just replace the rimjoust section? The car decking I’m not sure of the fix.

Have no idea what you mean by "car decking."
Sorry bout that, car decking is just west coast doug doug fir tongue and groove subfloor (we call it that here), it's rotted to about 4" in.
Just based on the picture I'm not convinced the rot is bad enough to be worth the fix. Of course there's no way to be sure with out being there.
Whatever you do of course you need to see that it doesn't get worse. My first thought is to pain the exposed rim with copper napthenate then flash it properly and add exterior components also properly. Would require some planning.
Then I'd try to figure out how to support the deck without attaching it to the rim at all. Again, just going by the pics that looks easy. It is possible to fasten a deck to a house directly but is not simple to do properly.
Thanks oldhand. There's a 700 pound stove and pedestal combo above it, and I think it's probably bowing the rimjoist a bit. Hard to see in the pics.
I've been thinking about a stand alone deck, because it's well built, and just 1 beam needs replacement. I'd rather not attach it again as there isn't much drop between the house and the deck, 1.5" maybe.
The subfloor (car decking), is pretty mushy on 3 or 4 boards, and those are holding the stove.
Thanks for the reply.
