I get what you’re saying about metal being safer for lightning, but I’ve seen a few cases where people didn’t have proper grounding and it caused issues. It’s not just the roof—it’s how the whole system’s set up. Condensation’s tricky too, especially in humid spots. Sometimes even with vapor barriers, if the airflow isn’t right, you still get those drips. Curious if you noticed any mold before you fixed it?

That’s spot on. I’ve seen jobs where folks thought a vapor barrier was enough, but without solid ventilation, mold crept in anyway—usually around the eaves. The worst was a lake cabin where you could actually smell it before you saw it. Grounding’s another one... people assume having a metal roof is magic for lightning but skip the proper setup and end up with fried appliances.
I used to think a metal roof basically turned your house into a giant lightning rod, but after reading up (and talking to my neighbor who’s an electrician), it’s not really the roof that’s the problem—it’s whether or not you’ve got proper grounding. My place came with a metal roof and zero clue about grounding, so I had an electrician check it out. Turns out, if you skip that step, your appliances are toast if lightning hits nearby. Metal doesn’t attract lightning more than other roofs, but if it does get hit, you want that energy going somewhere safe... not through your TV.
I used to have the same worry when we switched to a metal roof a few years back. My wife was convinced we’d be zapped every time there was a thunderstorm, but honestly, it’s been fine. The electrician who did our install said pretty much what you heard—metal doesn’t attract lightning, but if it does get hit, you want that current to go somewhere besides your living room.
We’re in the Midwest, so storms are just part of life here. I did ask about surge protectors for the big appliances, just in case. Anyone else do that? Or is that overkill? I will say, the noise during heavy rain is something else... kind of cozy, but sometimes it sounds like a drumline up there.
Curious if anyone’s actually had lightning hit their metal roof? Did grounding do its job? I’ve only heard stories, never met someone who had it happen directly.
I’ve actually had a close call with lightning and a metal roof, though not a direct strike—more like the neighbor’s tree took the brunt of it and we just got some of the aftermath. Our place is in central Illinois, so we get those wild summer storms, and I’ll admit I was on edge the first year after switching from asphalt to metal. The installer was adamant about proper grounding, which honestly seemed like overkill at the time, but now I’m convinced it’s worth every penny.
The surge protectors? Not overkill in my book. After that storm, our neighbor lost his fridge and TV—fried from a surge, even though his house didn’t take a direct hit. We had protectors on our major appliances and didn’t lose a thing. Maybe it’s luck, maybe it’s the extra layer of protection, but I’d rather spend $30 on a good surge protector than risk replacing a washer or stove.
As for the noise, yeah, it’s loud. Sometimes it’s oddly soothing, other times it feels like you’re living inside a snare drum. I’ve gotten used to it, but guests always comment when there’s a downpour.
I’ve heard the same myths about metal “attracting” lightning, but everything I’ve read (and what our electrician said) lines up with your experience—it doesn’t attract lightning any more than shingles or tile. The key is giving that energy somewhere safe to go if you do get hit. Grounding is non-negotiable in my opinion. If your installer skipped that step or did it halfway, I’d be worried.
One thing I wish someone had told me: check your insurance policy after switching to metal. Some companies cut rates because of fire resistance, others don’t care. Ours dropped by about 10%, which was a nice surprise.
Long story short: proper grounding and surge protectors are cheap insurance for peace of mind. The noise is just part of the package. Wouldn’t switch back to shingles even if you paid me—too many hailstorms here for that gamble.
