Honestly, I can see the appeal. Graphene is light and strong, and if you could coat the tiles and get a decent solar yield, it’d save on weight and maybe on the roof’s heat load. But I’d worry about the cost, the durability in a real roof weather scenario, and how long the coating lasts before it needs replacing. If the numbers line up and the contractor can prove it’s reliable, then sure, it’s worth a look. Otherwise, I’d stick with what’s tried and true.

I like the idea, but I’m still going to check the numbers first. If the coating can actually keep working after all the storms and the warranty data proves it, then it’s worth trying. If the cost keeps climbing and there’s no guarantee it holds up, I’ll stick with a solid roof that doesn’t need a second‑hand technology. Either way, I’ll make sure it’s installed the right way and monitored over time.
