When roofing contractors near me get a late‑night call, it’s usually bad news for the building owner. Last Friday in Neosho, Missouri, Ridgeline Roofing & Solar raced to a shopping mall with water pouring in around a rooftop A/C unit. The structure featured a trapezoidal standing‑seam metal roof—a workhorse system, but even the best metal roofing fails when water ponds around protrusions.
Our inspection revealed cracked sealants, fiber‑aluminum coating that trapped moisture, and rust forming on galvanized panels. Left unchecked, these issues drive up roof replacement cost and force emergency shutdowns. We stripped the failed coating, cleaned the curb, and applied high‑grade silicone roof sealant to restore watertight integrity. We also recommended installing crickets and proper drainage so ponding water can’t return.
Whether you manage a retail center, factory, or home, the same culprits—loose flashings, clogged drains, deteriorated sealant—cause leaks. Trust the commercial roofing contractors near me who answer 24/7. We bring thermal imaging, moisture scans, and years of metal‑roof expertise to every roof repair near me call.

So, this is a trapezoidal standing seam metal roof, and they're really good roofs. Selling problems you ever really have with them is just the roof's real long, and the panel doesn't go all the way the length of it. Then you have where they seam them together. And then typically, they have a a metal channel that runs over here, that actually helps push that panel down, but this one doesn't have it. But we're not having any trouble right there.
We're having trouble with this AC unit, and it's it's it's leaking around the AC unit. And and these are typically they're hard because you don't know if it's coming inside the AC unit and backing up and coming in the building by the the leak it's got going on right now or you don't know if maybe it's just coming in around it. So we we always look at the protrusions first and figure out if, you know, it's a possibility there, and it's got some some cracks. And it's it's obviously had some problems because they've got an acrylic sealant, and then they've got a, another sealant on top of that. It's not it's not actually a sealant.
It's a, aluminum, fiber aluminum coating. And that fiber aluminum coating is really not a waterproofer. It's it's just made to I've talked about this before, elongate the life of a roof on a modified. So, this, they say people put them on metal roofs all the time, though. But this is what I found to be what I think is the issue.
And the problem is, you know, the water's getting in there. You can see it. And because they put this this coating on here, you know, eventually it cracked out, and now water is building up on the inside. It's actually causing this panel to rust. You don't see that a lot on these panels because it's a galvanized panel, And, they tape the weather really well until you hold water on them.
And, that's what's going on here. So we're gonna probably have to tear all this off and clean that up, and hopefully that thing has enough integrity to to just put some real sealant on it, and, we'll probably use silicone and clean it up. Now all the other units on this roof are the same way, and they've actually built on this curb right here. They built a little bit of a cricket to kick the the water out to the side of it, but this obviously isn't enough pinch to make that water flow. So, we're gonna put in our thoughts on this and see what happens.
Hope you all have a good weekend. Thanks."
