I notice that one corner of the interior trim piece of the roof vent is sagging. Trying to tighten is does no good...it just turns. I know there is previous leak here as the ceiling material is bubbly. So i remove the other 3 screws to take a look...turns out the original screw was just turner because it was NEVER even in wood...missed the framing entirely. however, the 4 screw also just turned.

This is what i found when the trim was removed:










Im guessing the two pieces are irreparable...but the other two still look decent.

I know the leg bone is connected to the ankle bone and ceiling wood is connected to these framing members...but how much tear out is going to be necessary to remove them? I hoping to not have to tear off the whole section of ceiling...

first thing to do Scott, is to find where the leak is, so it doesn't happen again. Like you said, the leg bone, etc... You are just going to have to bite the bullet and tear into it. You might be able to pry the ceiling panel away from the vent frame enough to remove the rotted wood. Chances are the ceiling is stapled to the framework and the staples are probably rusted out anyway. Remember, you have a lot more between your ears then the guy that built it, so it's just a matter of seeing how far the damage goes and either repairing it, or hiding it before you sell it. Good Luck!

finding the leak source was fairly easy...



I'm in the process of resealing all my roof joints...but now see i have to pull the vent out first...

Correct, pull that vent and throw it away!! Get a new vent and a tube of the self leveling caulk. If the wood is still solid but just discolored I would leave it and use longer screws, or you can get a small dowel rod and insert it into the old holes and break it off flush, this will allow the same screws to bite. If the wood is rotten take a hack saw blade and run it along the framing top and bottom, this will seperate any fastners or glue that may he holding it in. Once that is done I would take a 3/4" spade bit and drill several holes vertically in the center of the member, take a chisel to break through the small areas that remain. This will allow you to remove the frame piece. Cut new piece to fit tight and glue in with Gorilla glue or liquid nails. Re staple or brad nail the ceiling back in place and replace with new vent and seal.

Thanks for the hacksaw tip....i probably woulda tryed to pry ceiling off the members which probably woulda broke up the ceiling...

Is there a difference btwn the self leveling caulk and the mounting "tape"? Caulk easier...better...etc?

That corner is shot...touched with screwdriver and was no resistance at all. I'm wondering...what are the chances that that light is attached to that member???

Looking at pic #2 above...you see a trim piece just this side of the light. What are the chances that that is a joint of the ceiling? in other words...if need be...could i remove that trim piece (what holds it on?) and then just the ceiling around this vent without "interacting" with the rest of the ceiling? Looks like the ceiling is only 1/8" ply...and the edges around the vent look like they are rotting also...

typically Scott, those strips are used to hide the joints where the two ceiling panels adjoin. I have seen them held up by staples, finishing nails, brads and/or glue. I would try to remove it, then loosen the offending ceiling panel and get into the framework of the vent hole. If you break the strip, you can always pick up a piece of similar trim at Home Depot and paint it off white. Only you would notice the difference.

Stop!!! Chances are the ceiling was applied prior to cabinets being installed so if there are cabinets at either end it will make removing the ceiling panel very diffcult. You don't want to find this out with the panel half way down!! I would follow my suggestions above, unless you are sure you can drop the ceiling panel in one piece, if you can it would make the repair much easier. Part of the negative of working on a RV is the way they are constructed.

No cabinets in this area...its the dinette below and an upper bunk...I'm "pretty sure" that the cabinet you do see in the pic doesnt reach the separation trim...




I probably wont be able to get to this until next weekend...so please keep all the tips coming...there's a lot i dont know...

ok...so the separation trim is about 1-2s inchs away from the pictured cabinet...+1 ...the pictured light is not connected to rotting vent framing member...+2

I'm going to go at this the simplest way first...by just removing the offending framing members...

however...

I dont see any nails or staples holding seperation trim in place...if glue i "should" just be able to run a knife on the good side so as not to disturb that ceiling? What is the white surface material on the ceiling? How is that held in place?

Looks like just a couple staples around the vent frame to clear the members of the ceiling...but im afraid once i remove the pictured members that cross members may also have issues...so am considering the option of removing ceiling here.
