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.
Been there, done that. I’m all for lightning rods, especially if you’re in a spot that gets hammered by storms. Insurance here doesn’t care unless you’re in tornado alley, but honestly, peace of mind is worth a couple hundred bucks and some copper wire.“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 The real issue is when folks skip grounding or leave outdated wiring untouched.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?

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.
