Zip board and Raptor Liner for new roof?
Been a long while since I’ve been on here but our 2008 Trail Lite is about to need a roof. I’ve made it last about as long as I can but am going to have to do something later this year. A friend of ou...

With the Zip you're probably adding a little more weight to the roof.
Are there any curves or bends the Zip will need to follow? I don't think Zip is very flexible. If the roof is flat, no problem.
I wouldn't expect it to act as a radiant barrier. It's not reflective and for a radiant barrier you need an air space above the barrier.
Could you use the Zip with insulation attached? It would raise the height of the roof but, give you some insulation.
I'm not familiar with the spray on liners you plan to use on the roof.
Your plan should work, assuming the spray does not react with the Zip coating and tape.
Roof does have a curve to it but it is not much. Maybe 1” higher in center than the edges. I will obviously have to go look at the ZIP board and see if it will flex at all.
My other thought was to install the silver Reflectix bubble insulation on the bottom side of the arched “rafter” giving the airspace needed or maybe under the decking itself sandwiching it. It wouldn’t causing the roof to be noticeably taller as it would compact down over the rafter pretty easily. I would just use standard 3/8” OSB or plywood like is there now and then the Raptor Liner over it.
Raptor Liner material is in-between Linex and Rhino in texture and feel. If it is good for a truck bed or even coating an entire car, I feel confident in its abilities to be used as an RV roof.
