So my buddy and I are tackling a roof repair on his travel trailer... 3 weeks out from our big whirlwind tour of the west, and we need some guidance... FAST! We're pretty handy, but we definitely need some pointers on the intricacies of this project.
As you can see in the photos, we've just about got everything torn apart that needs to be. The leak was where the rubber roof met the fiberglass that wraps the front of the camper. There is a fair amount of water damage to the wood on the roof (luan?) and we'll have to replace the first sheet on the roof from the front of the camper back to the first "rafter" or "joist" (about 4'). Also, water made it's way down behind the fiberglass on the front, and whatever was glued to the back of the fiberglass (looks like cardboard) is "no more." We will be completely removing the entire front piece of fiberglass...
So here are my questions:
1) Can the rubber roof be pulled away from the first sheet of luan that it's glued to in order to facilitate removal and replacement of the luan? We pulled a little bit of it back, but it's not very easy and plenty of luan sticks to the rubber.
2) The roof had previously been repaired (poorly) and the rubber doesn't even reach the fiberglass. We were hoping to buy a 12" wide strip of rubber roofing material to use as a patch (providing we can get the old rubber roof pulled away from the luan without damaging it). Is this acceptable, and if so what are the best sealants/adhesives to use to make this patch actually be water proof?
2a) What type of adhesive do we use between the new luan and the rubber roof?
3) What in the world is the cardboard-like stuff behind the fiberglass on the front? We need to replace it since the other stuff just fell apart. What type of adhesive do we use between the cardboard and the fiberglass, and between the cardboard and the camper?
4) How do we get what's left of the 'cardboard' and glue off of the fiberglass so we have a clean surface to glue the new "cardboard" to?
I think that's all for now... and and all help will be greatly appreciated.
