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 ours had their rubber roof removed and the roof coated with a bedliner type material.
I’m getting ready to buy Raptor Liner for a DIY spray in liner for my truck and figured, this should work for a roof material as well. It bonds to anything including wood, especially if epoxy primes first.
I need to pull off the roof decking to do some HVAC duct mods and run some wire circuits for the vent fans. I’m thinking that going back with 7/16” green Zip Board will help as it is weatherproof and seals very well. Also acts as a type of radiant barrier.
Seal all the vents and then Raptor line making it a seamless roof.
Anyone see any potential issues with this?

    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.
