Would you worry about lightning if your house had a metal roof?

You’re right about the fire resistance - having a metal roof in the PNW just feels safer with all the trees and wet weather. I had similar noise worries before mine went on (standing seam, too). Ended up going with a thicker underlayment, plus they put battens between the roof and the sheathing. That seems to help a lot with sound. When it rains hard, it’s more of a gentle tapping than anything crazy loud. My neighbor’s older barn, though, is a different story…that thing sounds like someone’s throwing gravel at it every time there’s a downpour.

On solar panels: I haven’t pulled the trigger yet but did some homework last year. From what I gathered, most insurance companies just want to know you’re using licensed installers and sticking to code - didn’t seem like a big premium jump in my case. The electrical inspector did mention making sure all the mounting brackets are properly bonded because of the metal roof, so that’s something to double-check if you move forward. Definitely worth asking your installer how they handle it so you don’t get any surprises later.

Not sure I totally buy the “feels safer” angle just because it’s metal. Yeah, fire resistance is a plus, but I’ve always worried more about lightning with a metal roof, especially out here where we do get the occasional summer storm.

“making sure all the mounting brackets are properly bonded because of the metal roof, so that’s something to double-check if you move forward.”

I get what you’re saying, but from what I’ve read, a metal roof doesn’t actually make your house more likely to get hit by lightning. It’s more about being the tallest thing around.

“metal roof or not, stuff happens”

- that’s true, but at least metal can help direct the strike safely to ground if it’s properly installed. I’d be more worried about old wiring inside than the roof itself, honestly.

I hear you about the wiring being a bigger worry, but I’d push back a bit on the “metal can help direct the strike safely to ground if it’s properly installed” part. That’s true in theory, but I’ve seen plenty of metal roofs where the grounding wasn’t done right or even skipped altogether. In those cases, the metal can actually make things worse - arcing or side flashes inside the house aren’t unheard of. If someone’s got a metal roof and isn’t sure about the grounding, it’s worth double-checking. Old wiring plus questionable grounding is a rough combo during a storm.

In those cases, the metal can actually make things worse - arcing or side flashes inside the house aren’t unheard of.

- Totally agree with the “old wiring plus questionable grounding is a rough combo during a storm.” That’s like inviting trouble over for dinner.
- Metal roof here, and I’ll admit, I just assumed it was all grounded right when we bought the place. Turns out, nope - had to get an electrician in after a neighbor’s shed got zapped and half his outlets fried.
- If you’re not sure about your setup, it’s worth poking around (or paying someone who knows what they’re doing). Peace of mind is worth more than a new TV after a lightning strike.
- One thing I learned: metal roofs don’t attract lightning, but if you do get hit, you want that energy going somewhere safe - not through your toaster.
- Also, old wiring is its own beast. Ours is from the 70s and every time there’s a big storm, I cross my fingers and unplug the fancy stuff. Not exactly high-tech, but it’s kept us out of trouble so far.
- Bottom line: metal roof isn’t the villain, but bad grounding + ancient wires = recipe for disaster.

- One thing I learned: metal roofs don’t attract lightning, but if you do get hit, you want that energy going somewhere safe - not through your toaster.

- “Peace of mind is worth more than a new TV after a lightning strike.” Couldn’t agree more with this. It’s amazing how many folks assume their roof (metal or not) is grounded properly, but then you dig in and find some pretty questionable setups.

- I’ve inspected a few homes where the metal roof *was* grounded, but the ground rod was barely sunk in or the wire was so corroded it wasn’t doing much. That’s almost worse than nothing at all - gives a false sense of security.

- The other thing I see a lot: older homes with two-prong outlets and no real ground path. Even with updated panels, if the circuits themselves aren’t bonded right, you’re rolling the dice every storm.

- Metal roofs themselves aren’t the culprit, but they do make you think about where that energy’s going. If lightning does hit, a well-grounded metal roof can actually help by directing it safely away, but if there’s a weak link - old wiring, bad connections - you might get those “side flashes” or interior arcs you mentioned.

- I’ve also noticed some folks rely on surge protectors thinking they’re covered. Helpful for small surges, sure, but not much against a direct strike if the main system isn’t up to snuff.

- Out of curiosity, for those with older homes: have you had your electrical panel or grounding checked since moving in? Sometimes previous owners did DIY work that looks fine until you trace it back and realize it’s not even tied to a real ground.

- Anyone ever seen a house with a lightning protection system (like rods and braided cable)? I don’t see them much around here, but I’m wondering if they’re more common in other regions. Seems like overkill in most places, but maybe not if you’re on a hilltop or out in the open.

- For what it’s worth, I’d rather have a metal roof with proper grounding than an old shingle roof with mystery wiring. Just my two cents.

I’ve run into a surprising number of homes where people thought their metal roof was “lightning proof” just because it was metal, but the actual grounding was a mess. One job last year, the ground wire was literally just wrapped around a copper pipe in the crawlspace - no rod, nothing sunk in the earth. The homeowner figured the metal roof was doing all the work. That’s a recipe for trouble if lightning ever does strike.

Agree with the point about older wiring too. I see a lot of houses with updated breaker panels but the original two-prong outlets and no real ground path. That’s a weak link most folks don’t think about until something goes wrong.

As for lightning rods, I’ve only seen them on a handful of farmhouses out in the country, usually on barns or silos. Around here, most homes don’t bother unless they’re really exposed. Personally, I’d rather see a solid ground connection on any roof - metal or not - than fancy hardware that’s not installed right. Peace of mind isn’t just about what you can see from the curb.

That’s a really solid point about the difference between having metal up there and actually being protected from lightning. I’ve noticed a lot of folks just assume “metal = safe,” but if the grounding isn’t done right, it’s almost like having no protection at all. The story about the ground wire just wrapped around a pipe... that’s wild, but honestly not that rare from what I’ve seen on older jobs.

I’m still learning, but it seems like even the best materials can’t make up for shortcuts in grounding or wiring. I get why people skip lightning rods unless they’re in a super exposed spot, but sometimes it feels like there’s more focus on what looks good than what actually works. I’d rather have a proper ground than some shiny hardware that’s not even functional.

It’s kind of eye-opening how many houses have those old two-prong outlets too. Makes you wonder how many hidden issues are out there just waiting for the right storm. Anyway, your take makes a lot of sense - peace of mind is definitely more than just curb appeal.

I get what you mean about the old two-prong outlets - my place had a bunch when I moved in, and it made me nervous thinking about what else might be outdated behind the walls. I’ve got a metal roof too, but honestly, I didn’t feel better about lightning until I had an electrician check the grounding and add surge protection. The roof itself is tough, but without proper wiring and a real ground, it’s just for show. Sometimes I think people forget a lightning strike doesn’t care how new your roof looks...

You’d be surprised how often I run into this - people assume a metal roof is some kind of magic shield, but without proper electrical grounding, it’s really not doing much to protect the house itself. I’ve managed a few older properties where the wiring behind the walls was a total mystery until we started opening things up. Sometimes you find cloth-wrapped wires or ancient junction boxes, and that’s where things can get dicey during a storm.

Surge protection is a huge help, but I’ve also seen lightning rods make a difference, especially on taller buildings or ones out in open areas. Curious if anyone here has actually installed a dedicated lightning protection system? I know some folks say it’s overkill for residential, but after seeing what a direct strike can do to appliances and even foundations, I’m not so sure it’s just paranoia. Does your insurance company care about that stuff in your area, or is it more of a personal peace-of-mind thing?

I get what you’re saying - people think a metal roof is like a superhero cape for their house, but if the wiring’s sketchy or there’s no grounding, it’s just for show.

“Sometimes you find cloth-wrapped wires or ancient junction boxes, and that’s where things can get dicey during a storm.”

I totally get the peace of mind thing - after a close call with a lightning strike a few years back, I added rods too. Metal roof or not, it’s the old wiring that worries me most. Ever had to rewire a section just because you found something sketchy? I swear, some of the stuff hiding in walls is wild.

I hear you on the old wiring - sometimes I think that’s a bigger risk than the roof itself. But I’d actually argue a metal roof, if it’s properly grounded, can be safer in a lightning event than asphalt or wood. It acts like a shield, dispersing the energy. The real issue is when folks skip grounding or leave outdated wiring untouched. I’ve opened up walls and found cloth-wrapped wires spliced with tape... not exactly confidence-inspiring. If you’re already upgrading for lightning, might as well check the wiring while you’re at it.

I’ve seen some wild stuff behind old plaster - knob-and-tube, random junctions, even a melted wire once. Honestly, I trust a grounded metal roof more than some of the Frankenstein wiring jobs I’ve come across. Has anyone had insurance push back because of old wiring during a roof upgrade?

Honestly, I trust a grounded metal roof more than some of the Frankenstein wiring jobs I’ve come across.

That’s the part that really hits home for me. I’ve pulled up old shingles and found stuff that makes you wonder how the house hasn’t burned down already - random splices, charred insulation, wire nuts just hanging in midair. It’s wild what gets buried behind walls and ceilings. The metal roof, when it’s properly grounded, is probably the least of your worries compared to 1920s knob-and-tube still in service.

Insurance can be a mixed bag with this stuff. I’ve seen underwriters get way more worked up over ancient electrical than anything on top of the house. Had one homeowner in my area (central PA) who was getting a standing seam roof put on, and the insurance inspector flagged his ungrounded wiring from the attic photos - delayed the policy update until he got an electrician in to do a partial rewire. They didn’t care at all about the new roof being metal; it was all about what was lurking underneath.

If there’s any pushback, it’s usually because the old electrical is seen as a bigger fire risk than lightning ever could be with a modern metal roof. Most adjusters I’ve met seem to know metal roofs don’t actually attract lightning - they just safely conduct it to ground if they’re installed right. But those Frankenstein jobs? That’s what keeps them up at night.

I get why people worry about lightning and metal, but honestly, the real danger is usually hiding in the attic or behind plaster. If you’re upgrading your roof and your insurance gets nosy, nine times out of ten they’ll want to see a safe electrical setup before they care about what material is over your head.

If you’re already tackling a roof project, it might be worth having someone peek at the wiring too. Not saying you need to gut everything, but even swapping out the worst offenders can make a big difference with insurance - and your own peace of mind.

I get where you’re coming from, but I’m not totally convinced the insurance folks are always as chill about metal roofs as you say. Maybe it’s a regional thing? Around here (southern Ohio), I’ve had two neighbors get hassled about switching to metal - one even had to send in extra paperwork about “lightning mitigation” before they’d update his policy. Meanwhile, his breaker panel looked like a spaghetti dinner and nobody blinked.

Not saying old wiring isn’t a bigger risk, but sometimes the adjusters seem more worried about what’s new and shiny than what’s hiding in the walls. Maybe it depends on who shows up with the clipboard that day...

Personally, I’d still rather deal with a little extra paperwork for a metal roof than wake up to the smell of burning insulation. But yeah, wish insurance was more consistent on this stuff.

That’s interesting about the insurance angle in your area. I’ve actually seen similar cases - sometimes they get more hung up on the new metal roof than the old fuse box, which seems a bit backwards to me. From what I understand, a metal roof doesn’t attract lightning, but it does a good job of dispersing the energy safely if it’s installed right and grounded. Have you noticed if your neighbors’ policies required actual lightning rods, or just extra paperwork? Sometimes it’s just a checkbox thing, sometimes they want a whole system. It’s not always logical, but that’s insurance for you...

Yeah, I’ve noticed the same thing - insurance companies can be weirdly inconsistent. Around here, a few neighbors with metal roofs got flagged for “increased lightning risk” on their policies, but none of them actually had to install full lightning rod systems. Mostly it was just extra forms and a higher premium, which honestly felt like a money grab. Meanwhile, I know at least two houses with ancient wiring and no GFCIs that never got a second look.

I agree, metal roofs don’t attract lightning any more than shingles do. If anything, they’re safer since they’ll conduct and spread out the charge if grounded right. My installer made a big deal about proper grounding, but the insurance folks barely seemed to care about that part - just wanted to check their boxes.

It’s frustrating when logic goes out the window. I’d be more worried about old electrical than a new metal roof, personally. But I guess that’s not how the paperwork works...

That’s wild about the insurance stuff. I just bought my first place and was actually hoping the metal roof would be a plus, not a red flag. I did some reading and it sounds like, if anything, it’s less likely to catch fire from a strike compared to shingles. The old wiring thing freaks me out way more - my inspector flagged a couple outlets with no GFCI and that’s what I’m prioritizing. Feels backwards that insurance cares more about the roof than what’s running through the walls...

Funny, I had almost the exact same reaction when I bought my place - thought the metal roof was a huge bonus, not something to worry about. I’m in the Midwest, so hail and storms are just part of life, and every old-timer around here swears by metal for longevity. The fire thing especially - metal doesn’t burn, so I figured that was a win. My insurance agent, though, practically acted like I’d installed a trampoline on the roof or something. Apparently, they worry more about the cost of replacing metal if it gets dented or “cosmetic” hail damage than about it catching fire.

Lightning-wise, I dug into this when I moved in, because I had visions of the whole house turning into a giant bug zapper during storms. Turns out, metal roofs actually help disperse the energy if you do get struck. It’s not like the roof attracts lightning more than any other material; it just gives the electricity a path to ground. My neighbor has had a metal roof for 30 years and never had a single issue. Meanwhile, the house two doors down with old cedar shakes did catch a small fire after a lightning hit a few years back.

The electrical stuff inside freaks me out way more, too. I had some ungrounded outlets and no GFCI in the kitchen when I moved in, and that was top of my list - especially since I’ve got kids. Insurance never even asked about it, which seems nuts. I guess roofs are easier for them to check off a list than wiring hidden behind drywall.

If you’re worried about lightning, you could look into surge protection for your main panel. That’s what I did - just a little extra peace of mind, especially with all the electronics we rely on now. But honestly, I’d take a metal roof over old asphalt any day, especially with the storms we get.

Anyway, I wouldn’t lose sleep over the roof. But yeah, I’d put those GFCIs in ASAP. It’s weird what insurance companies focus on sometimes... their priorities don’t always line up with what actually keeps a house safe.
