I hear you on the “just cosmetic” thing—my neighbor’s roof looked like a golf ball after last year’s hail, but it never leaked. Mine, on the other hand, had a couple tiny dings and I found a wet spot in the attic a few weeks later. Turns out one of the seams got knocked loose. I guess it really depends on how old the panels are and if they were installed right in the first place. I always peek in the attic now after a big storm, just in case.
That’s exactly why I always say it’s not just about what you see from the street. People love to talk up metal roofs as “hail proof,” but like you found, it really comes down to the install and how well the seams are sealed. I’ve seen newer panels with barely a scratch leak like crazy after a storm, while some older ones just get dented and keep going.
Honestly, I think a lot of folks underestimate how much those little dings can mess with the protective coatings too. Once that’s compromised, rust can sneak in over time, especially if you’re somewhere humid. I’m all for metal roofs—less landfill waste, way longer lifespan—but only if they’re put on right and checked after big weather.
I started using a thermal camera to check for wet spots in the attic after storms... probably overkill, but it caught a slow leak before it got bad. It’s wild how much difference a good install makes compared to just slapping panels up and hoping for the best.

I get where you’re coming from, but I’ve seen plenty of coated steel panels take a beating and still hold up for years, even with some dings. The key is the type of coating and the gauge of the metal. Thicker panels with Kynar finishes, for example, are way less likely to rust from minor hail damage. Not saying you can ignore dents, but sometimes folks worry more than they need to—especially if the paint system is high quality and there’s no exposed metal. Regular inspections matter, but not every dent spells disaster.
I hear you on the coatings—some of those finishes are tough as nails. My neighbor’s metal roof took a hailstorm last spring, and honestly, it still looks fine except for a few cosmetic dings. Maybe it’s more about peace of mind than actual risk sometimes? I do wonder if folks in super salty coastal areas have a different experience, though...
Funny you mention the salty air—had a job out near the coast last year, and I’ll tell you, those metal roofs take a real beating from the salt. Even with the fancy coatings, you start to see little spots of rust way sooner than inland. Still, after a hailstorm, most folks are surprised how minor the damage is. I think you’re right—it’s often more about feeling secure than actual structural risk. Cosmetic dings bug some people more than others, though...
