That “if you can’t see daylight, it’s fine” line gets thrown around way too much. Drives me nuts, honestly. Water finds its way in through spots you’d never expect, and by the time you notice, the damage is already done.
This is spot on. The “daylight test” is one of those old-school rules that just doesn’t hold up with metal roofs, especially after hail. I’ve inspected plenty where everything looked tight from below, but once you’re up there, you find washers that are split or even missing entirely. Hail has a way of flattening those neoprene washers so they lose their seal, and then water starts tracking along the fastener threads. You won’t see it until you’ve got staining inside or—worse—hidden rot.
I get what you mean about adjusters calling it cosmetic. Technically, a lot of small dings don’t cause immediate leaks, but over time, those impact points can break the paint or coating and start rusting. Once corrosion sets in around a fastener or seam, it’s just a matter of time before you’re dealing with a real problem. I’ve had to explain this to insurance folks more times than I can count... sometimes they listen, sometimes not.
One thing I’ve started doing is using a moisture meter on the decking from the attic side after a big storm. If you catch elevated readings early, you can document it before there’s visible damage. Not every homeowner wants to go that far, but for folks who’ve been burned by “cosmetic only” claims, it’s worth the extra step.
And yeah, photos and notes are huge. I always tell people to take close-ups of any new dents or marks right after a storm, even if they seem minor. It’s tedious, but when you’re arguing with an adjuster six months later, having that timeline makes all the difference.
Funny thing—last year I had a job where the owner kept every inspection report and photo for ten years. When we found leaks after a hailstorm, he had proof that the damage was new and not “pre-existing.” Insurance paid out without much fuss for once. Doesn’t happen often, but it’s possible.
Metal roofs are tough, but they’re not invincible. Maintenance and documentation go a long way, especially in hail country.

That’s exactly what happened to us last spring. Looked fine from the ground, but I found rust streaks under a couple screws when I finally crawled up there. Insurance adjuster called it “minor cosmetic,” but six months later, we had a soft spot in the decking. Wish I’d documented it better at the start—lesson learned.
Insurance adjusters and their “cosmetic” labels, right? Been there—ours said the same after a hailstorm, but fast forward a few months and I’m patching up plywood. It’s wild how something that looks fine from the yard can be hiding a soggy mess underneath. Don’t beat yourself up about the documentation thing… I swear, unless you’re up there with a camera every time it rains, stuff gets missed. At least now you know what to look for—silver lining, maybe?
I get what you’re saying about hiding damage, but I’ve gotta push back a little on the “cosmetic” label being all bad. I mean, yeah, it’s frustrating when the adjuster shrugs off dents and dings like they’re just battle scars, but sometimes that’s really all it is—at least with metal roofs. Mine took a beating in a hailstorm last spring (golf ball size, no joke), and I was convinced we’d be dealing with leaks or rust by now. But after crawling around up there (not my favorite Saturday), turns out it was just some ugly dimples. No leaks, no rot, just… less curb appeal.
That said, I totally get the paranoia. My neighbor’s asphalt shingles looked fine from the street after the same storm, but he ended up with water spots on his ceiling two months later. Guess it depends on what you’ve got up there and how old it is. Metal seems to take a punch better than shingles, but when it does fail, it’s usually pretty obvious—like actual holes or seams popping.
I do wish insurance folks would be more upfront about what “cosmetic” means for different materials though. It’s not always apples to apples. And yeah, documentation is a pain—I tried to keep photos after every big storm for a while, but then my phone filled up with 200 pictures of clouds and blurry roof corners. Not exactly helpful.
If nothing else, these storms are making me way too familiar with my attic insulation... and my ladder skills are still questionable at best.
I hear you on the “cosmetic” call—sometimes a dent really is just a dent, but I’ve seen those same dings start to rust after a couple rough winters. Did your roof have any kind of special coating, or is it bare metal? I’m always curious if that makes a difference when it comes to long-term damage versus just ugly spots.
