Adhesive for Aluminum roof to plywood?
My husband and I are rebuilding a camper and are about to get to our roof install. We are doing a seamless aluminum roof which will be going over plywood. We want to avoid using any type of screws as ...

The aluminum sheet on the roof of my TC isn’t glued to the wood at all. IIRC there is a layer of felt or closed cell foam between the aluminum and the wood, but it’s held down by the perimeter trim and screws. I don’t think I’d try to full-spread glue it.
I would also pass on the EPDM, TPO, or any other flexible membrane roofing. Nothing beats aluminum.
In other words, what he said ^ :B

yes you will want the felt or some kind of insulation that aluminum is going to sweat not a good situation.

RV and Mobil home manufacturers NEVER put anything under an aluminum roof. Yes, I HAVE worked on mobile homes and I HAVE delt with RVs with aluminum roofs, there is NOTHING THERE, not even plywood.
The aluminum just lays over top the roof ribs..
Not saying it is the best way, just saying that IS what has been done.
You are always free to do what you think is best..
Well, no offense intended, as all I know are the three TC’s I’ve owned. The 19 year old Lance In my sig, and two Jayco TC’s before that. All had a seamless aluminum roof, and there was definitely more than just the aluminum up there. Probably because TC’s don’t sit on a steel frame like a trailer, and their roofs are usually intended to be walked on. But, the construction of the trailer they’re rebuilding sounds very similar.
The only TC I’ve had to open up the roof on is the Lance, and there is a layer of some type of insulation between the aluminum roof, and the layer of plywood or luan that’s on top of the ribs. The voids between the ribs are filled with more insulation, then the ceiling plywood is on the inside.
The OP’s trailer that they are rebuilding also has plywood over the roof ribs, whether by their design or the OEM. If it were my camper, I wouldn’t try to adhere the aluminum to the plywood, but would put a thin (~1/8”) layer of some type of felt or foam insulation between. Mainly because I believe it will help quiet the roof when it rains, but it may also have some benefit in preventing condensation.
