Fiberglass roof replacement

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?

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.

Is the inside damaged or just a few stains, cause if the inside is still ok just do the top layer outside or seal over the old roof with white snow roofing material.

the luan inside is bad in places, and exterior roof is very delaminated, rood sealed up for this year as winter is closing in here in ND exterior will be in spring. We will be using this often as our young boys race motocross.

very musty smell interior as roof had not been fixed by previous owner in a very timely manner. Any quick remedies for help with that?

That smell might be mold, I hope you got this very cheap..

we got for 20k under anything else for the age/mileage. Unfortunately we found more wrong after arrived home. Like I said many lessons learned but for what we have invested we need move forward and get over it.
