Why not work from the roof?
I've done (2) roofs recently. Take the material and lay it out over the roof. Once you're satisfied with where it's at roll it up to one end. Next put your glue in a paint tray and roll it on a section at a time, unrolling the TPO on to the glued section as you go. I normally do 4-5 feet at a time. Use a floor squeegee or broom to work any bubbles out as you go. It really isn't a bad job. The first one I did I was thinking I'd need help. When I was ready to do it no one was around so I figured I'd get started. Easy job. When I did the second one I didn't want anyone around.
On the glue, check with your local roofing supply house or RV dealer. When I was looking I found the glue was cheap enough, the freight wasn't. My local RV dealer buys it in buckets - they were happy to sell me a few gallons.
I'll call the outfit I got the TPO from. I am not sure, but I think the TPO adhesive for this, MAY be a contact adhesive. If it is, that may be a little of an issue for me.
Since the roof is curved, I am not sure I can roll this out, from front to rear, without inducing wrinkles. If it's not contact adhesive, and I only have to roll it on the roof, that would make things a lot easier.
Either way, I would think it would be easier to avoid wrinkles starting in the center of the roof, side to side, and rolling out towards the edges. Then again, since I haven't done this yet, I could be wrong.
I am also dealing with a much heavier TPO than is typically used on an rv, so that may help things go better, or worse.
Can you tell, I really don't know?
