Holie roof

Actually, it does because if it did not leak, the aluminum skin would not have corroded. No water intrusion = no corrosion.

Gave you your options, go with it or something else.

No problem. Have a good day... I'm done with this thread.

Thanks, dont care about how wood rots though. Im fixing damage. like I said, not the issue.

I guess I need to rip out the styrofoam also since it is saturated, or will it dry now that the ceiling is out?

Wood underwater does not rot, it needs air. Mine stayed wet all the time and I was intrigued that it had not rotted.
but That is a non-issue here though. Has no bearing or significance. tks

It's not underwater, it's exposed to water and air. Wood will rot underwater unless it's 40 retention and even then it eventually rots.

No going to spar with you on it. I've seen plenty of rotted wood frames on RV's in my time. Not my first rodeo by a long shot.

You might try putting in a dehumidifier. Natural drying could take months...if at all.

Wood does rot when wet (and enclosed and light tight). What happens to RV's they rot. The reason why your aluminum roof perforated in the first place was water under it and the water coupled with the mold, attacked the aluminum from the underside causing corrosion and your hole issues. It corroded from underneath not from the outside.

After you mitigate the intrusion issue and only after, I'd repair the perforations with sheet aluminum sealed to the original roof with either Dicor or Sikaflex. Don't think Bondo is the correct solution to the repair.

Bondo a good idea.The roof is thin metal, will the Bondo crack if roof moves?

Sidecarflip, The water got the ceiling wet, the vinyl wall paper on ceiling kept it water tight, it stayed wet, not really rotted though.
I pulled it all out of areas over the metal framing, pulled plys off, and left the las ply that is bonded to the foam. Hoping it will dry and make things easier to glue back up as easier to glue to wood than this white foam.
One wall is wet, and everything except the exterior skin removed. Keeping the skin intact and fixing from the inside so I do not have to pull the entire outer skin off the 22 foot length… Hoping it works , no reason not to…

O'd be first concerned with what the leak did under the skin and then address the leak.

Bondo all purpose. Cheap, easy to work with and dries hard. Use slightly less hardener than called for and you have a little more working time. It will take a EPDM paint if you decide to coat the patch or the whole roof and if not will keep water out by it self.
