SWMBO's new object of desire is a house that happens to have a foam
roof. Neither of us had heard of that before. Yes I did a (dare I say
google) search. But I'd invite opinions and/or reports of experiences
with them...

I was looking at re-roofing my commercial building a few years ago with
foam. I have a flat roof and foam seems to be the way to go but its was
quite pricey so I ended up with a conventional roof. From my understanding
it will last 40 or more years but needs re-spraying every few years.
