Hello everyone, New member with major questions. Just bought our 1st Class A. Learned alot ot lessons already....so entire roof will need replaced in and out due to water damage, been pricing it out and will accomplish this on our own. I've watched many many videos and see that most fiberglass roofs go around the roof radius, ours does not. has separate radius cap. any helpful info would be great. anyone else have this also?

I "assume" that the fiberglass is OK and you need to rebuild the wooden trusses/supports/etc. as they are rotted out? why not just rebuild like original?bumpy

I will rebuild with new filon, lauan (luan) exterior and new lauan interior with padded marine vinyl. just curious if anyone has they same roof (stopping on top of rv vs rounding radius edge). or done this also.2006 forest river Charleston 400ts.

I would replace the fiberglass with new. You can buy it in sheets to fit your rig. You can do it. Take off the items on the roof, remove the caulking that covers the sealing strips, and remove the strips. Get advice on the proper caulking (Dicor?) Remove and duplicate the damaged trusses etc. If you can do the job in a covered enclosure would be ideal. Pick up new seals for the air conditioner. Note whether they have used any adhesive etc. It's a big job, but just take it step by step and you'll succeed.

I helped a guy fix his fiberglass roof because it was disinegrating. Your looking at a very big job.

my roof is aluminum framed so trusses wont br an issue... As far as being a large job yes I know. but saving thousands of dollars is sure nice also.

Finding more when you get home is not uncommon, probably more like the norm. The smell is a combination of dry rot and mold. No quick remedies except maybe a dehumidifier would help; I mean a machine, not the Dry's the air stuff. Keep it covered to stop any more damage. You could also put a hepa filter in it to catch mold spores.

An ozone machine would also be a good idea.

If it were me, with a bad filon roof, I would peel off all that I could and replace all of the luan plywood that has rotted. Then I would contact one of the guys that sprays bedliner on trucks and have them coat the entire roof with a white permanent solution. Then you can reinstall your AC unit and roof vents.
The spraying takes a few hours and the next day it is cured and ready to go.

Curious, HOW LONG and HOW MUCH money do you think it will be to get the RV ready? This is NOT like rebuilding a house. Doug
