This is the way I look at these products, and similar products.
First, the Permakote application was applied because the underlying roof either failed or was failing.
Now, several things must happen.
Second, the Permakote must be approved as a roofing system (when used as a water proof barrier, not if just "painting" it a different color) and a re-cover roofing permit must be obtained. That is because this is serving as a re-cover.
Then, the manufacturers installation instructions must be followed, this includes any requirements for cleaning, filling gaps in the underlying roofing, priming, etc. (I'd have to read the instructions on this specific product to list everything, the above is based on other similar products used down here).
Now, we need to refer to back this: The underlying roof was failing (or had already failed) and was (still is) in need of replacement.
Finally, would you want to buy a house with a roof coated with Permakote instead of having been re-roofed?
If the answer is 'Yeah, that'd be okay with me, no need to re-roof.' then advise your client of that, heck, they may even sell this house to you.
If the answer is 'No way would I want to buy a house with a failed roof, even if it has been coated with Permakote, unless the roof was replaced or I got compensated for the roof.', then, well, advise your client that same thing.
