Wait. In a grow room its meant to reflect visible. But on a roof, its looking to reflect IR. Nut much heat in visible. IR holds the vast majority of heat from all I've read/known. (I could be wrong. An engineer? Of? No shot at ya! I dig ya, and ya seem good. put me in my place! I just wanna learn all I can)
I work on IR lasers for cutting metal. I'm a field engineer. Been in optics for 15+ years
(oh, we are talking about the roof paint, yes? if not, disregard
)
