Just days ago, I finished a roof replacement on our 34-foot motorhome. I used the thin lauan panels, construction adhesive underneath, and lots of screws. I chose a PVC roof as replacement, wanting to avoid maintenance. Some of the old roof was unattached and some was stuck so firmly that trying to remove it was tearing the old plywood apart.
On our RV, all edges are underneath aluminum strips. I used butyl caulk underneath the sheet, underneath the aluminum trim strip, over every screw head, and along the edges after the plastic trim strip was installed.
I made notes about the install, but have not composed it yet. For our motorhome, the job took about 40 hours. Other than positioning the air conditioners on the new roof, I did the job entirely myself.
There are several good videos on Youtube. Do remember that the glue and caulk can be different for different roof materials.
