That’s a totally fair reaction—my folks used to unplug the TV and even the toaster whenever a storm rolled in, so I get it. The thing about metal roofs is, yeah, they’re big conductors, but that can actually work in your favor if the system’s grounded right. I’ve seen a few cases where poorly grounded sheds or barns got hit and stuff inside got fried, just like your neighbor’s lawnmower. But houses are usually built to stricter codes, with grounding rods and all that jazz.
One thing I’ve noticed: after big storms, it’s usually the older houses with questionable wiring or no proper lightning protection that end up with real damage—regardless of roof type. Metal doesn’t attract lightning, but if it does get hit, it’ll spread the charge fast and (ideally) send it safely into the ground. Shingles won’t stop a strike either; they just don’t conduct, so sometimes you get fires instead.
Honestly, I’d still double-check the grounding if I had a metal roof. Peace of mind counts for a lot, even if the stats say you’re safe.
I get where you’re coming from—my place has a standing seam metal roof, and I was a little nervous at first too. But honestly, the grounding setup is what really matters. I actually feel better knowing the metal will just shunt the energy down if lightning ever does hit. My neighbor’s old farmhouse with wood shingles caught fire last year after a strike, so I’d take a grounded metal roof any day. Still, I double-checked my grounding rods after moving in... just for that extra peace of mind.
Not sure I totally agree that metal roofs are always the safer bet with lightning.
—yeah, grounding helps, but if the system isn’t installed right, that metal could still cause issues. I’ve seen a couple jobs where shortcuts were taken and it made things worse, not better. Just saying, I’d be more worried about proper installation than just the material itself.“the grounding setup is what really matters”

Totally get where you’re coming from. I’ve seen some pretty sketchy installs too, and it’s wild how much difference a good grounding setup makes. My neighbor’s metal roof actually got hit last summer, but because everything was done right, there wasn’t any damage. I’d say the peace of mind comes more from knowing the job was done properly than just having metal up there.

That’s pretty much how I see it too. I was nervous about the metal roof at first, but after watching the crew double-check all the grounding and flashing, I stopped stressing. If you’re not sure about your install, might be worth having someone check it over.
