I get where you’re coming from, but I’d still be a bit cautious about the “better path to ground” part. If the metal roof isn’t bonded and grounded properly—especially with solar panels in the mix—you could actually increase the risk of side flashes or electrical surges inside the house. I’ve seen cases after big storms where improper grounding led to fried electronics, even when the roof itself was fine. It’s not that metal attracts lightning, but it does change how a strike behaves if it happens. Just something to keep in mind, especially with all that extra hardware up there.

That’s what worried me too. I went with a metal roof to save money long-term, but after adding solar, I started noticing weird power flickers during storms. Turns out, my installer hadn’t bonded everything right. Cost me a few hundred extra to get it fixed, but honestly, it was worth it for peace of mind. I’d say if you’re on a tight budget like me, don’t skimp on the grounding part—even if it means cutting back elsewhere. Fried appliances aren’t cheap to replace.
