Noise is definitely noticeable during heavy rain or hail, but it's not as bad as people make it out to be, especially if you've got solid insulation and decking underneath. The myth probably comes from old barns with no insulation at all. About heat—metal actually reflects a fair bit of sunlight, so with a “cool roof” coating and proper attic venting, it often stays cooler than asphalt in summer. Recycled metal options work just as well; the main thing is making sure everything’s installed right.
I used to think a metal roof would basically turn my house into a giant lightning rod, but after living under one for a few years, I’m not convinced it’s any riskier than anything else. It’s grounded just like any other roof. Honestly, the only thing I notice is what you said—
—which is true. The thunder sounds wild, but that’s about it. My neighbor’s got asphalt and his TV fries every summer storm, so maybe it’s just luck... or bad wiring.Noise is definitely noticeable during heavy rain or hail, but it's not as bad as people make it out to be
Yeah, I used to have the same worry about metal roofs and lightning. Turns out, metal actually helps disperse the energy if your house does get struck, especially when it’s grounded right. It’s not like the roof is attracting lightning more than a regular one—lightning’s gonna hit the highest point no matter what material you’ve got up there.
Noise-wise, I agree it’s noticeable, but honestly, I kind of like it. There’s something kind of relaxing about rain on metal, even if hail can get a bit wild. The only thing that bugged me was when we first moved in and had to get used to the sound at night.
Funny about your neighbor’s TV—makes me wonder if the wiring or surge protection is the real issue. I’ve heard that metal roofs can actually help protect against fire from lightning strikes, since they’re not going to catch like wood or old shingles. Not saying they’re perfect, but I’d take metal over asphalt again, especially with the storms we get around here.
Metal roofs and lightning get talked about a lot, but honestly, the risk isn’t what most people think. Here’s how I usually break it down for folks who ask:
1. Metal doesn’t attract lightning. It’s just as likely to get hit as any other roof at the same height. Lightning’s looking for the fastest path to ground, not a specific material.
2. If lightning does strike, a properly grounded metal roof actually helps. The metal spreads the energy out and sends it safely to the ground, instead of letting it concentrate and possibly start a fire. That’s a big plus over wood or asphalt, which can burn.
3. Grounding is key. If your roof isn’t grounded right, you could have problems—arcing, damage to wiring, or even fire. I’ve seen a few cases where folks skipped this step and paid for it later. If you’re not sure, get an electrician to check your setup.
About the noise—yeah, rain on metal is louder than on shingles. Some people love it, some hate it. I’ve had clients who couldn’t sleep the first week after switching, but most get used to it. If it’s really a problem, adding insulation or a solid underlayment can help cut the sound.
That neighbor’s TV issue sounds more like a surge problem than anything to do with the roof itself. Lightning can travel through wiring and fry electronics if there’s no surge protection. I always recommend whole-house surge protectors, especially in storm-prone areas.
One thing I’d add: metal roofs are tough, but hail can dent them. It won’t usually cause leaks, but if you care about looks, that’s something to think about. Insurance sometimes covers hail dents, but not always.
If I had to pick between metal and asphalt in a stormy area, I’d go metal every time. Less fire risk, longer lifespan, and fewer blown-off shingles after a big wind. Just make sure it’s installed and grounded right, and you’re set.

This is honestly the biggest reason I ended up going with metal when I re-roofed. I was nervous about the lightning thing too, but after digging into it, the fire risk with asphalt or wood seemed way worse. I live in a pretty stormy spot (Midwest), and we’ve had some nasty thunderstorms, but I sleep a lot easier knowing my roof isn’t a tinderbox.
I will say, the noise is real. First week after install, the rain sounded like someone dumping marbles on a tin can. Drove me nuts. But after adding a layer of foam board insulation, it’s not much louder than my old shingles. If you’re on a tight budget, that’s an extra cost, but worth it for peace and quiet.
One thing I wish I’d checked: my insurance didn’t cover cosmetic hail dents, just leaks or structural damage. If you care about resale, look into that ahead of time. But for me, the longer lifespan and lower fire risk made the extra up-front cost worth it.
