Put a fresh coating on my metal roof about two years ago, and it’s already flaking in spots. I followed the directions, cleaned everything, waited for the right weather, all that jazz. It’s like I just can’t win with these coatings—either they don’t last, or they cost a small fortune. Is this just a thing with metal roofs in hot climates, or am I missing something obvious?
Had the same thing happen on my place in central Texas—metal roof, did all the prep, even splurged on a “premium” coating. Two summers later, it’s peeling like sunburn. I’m convinced these coatings just can’t handle the constant heat and UV. Honestly starting to wonder if it’s even worth redoing or just living with the ugly patches.
I hear you—Texas sun is brutal on pretty much everything, but those coatings seem to be especially short-lived. I went through the same cycle: cleaned, primed, paid extra for the “good stuff,” and it still looked rough after a couple years. Honestly, I ended up just letting it go for a while. The patches bugged me at first, but after a bit, I realized it didn’t really affect the function, just the look. If leaks aren’t an issue, sometimes it’s not worth the hassle (or cost) of redoing it every few years. If you do decide to try again, I’ve heard some folks swear by elastomeric coatings, but I’m skeptical they’d last much longer in our heat.
