I’ve seen coatings peel up after just one bad hailstorm, even when the prep was solid. It’s frustrating, but sometimes it’s the only option when a full tear-off isn’t in the cards. I did a patch job on my own place last year—old asphalt shingles, Midwest weather—and yeah, it bought me maybe two more seasons. Not ideal, but better than dealing with leaks every time it rains. Metal would be nice, but the price tag is brutal right now.
That’s pretty much par for the course with coatings, especially on older shingles and in places that get wild weather swings. Honestly, you did the right thing—sometimes a patch buys just enough time to plan for something better down the road. Metal is great, but yeah, those upfront costs can be a dealbreaker. If you’re ever stuck doing another patch, I’ve seen folks get a little more mileage by making sure everything’s bone dry and hitting the edges with extra sealant before rolling on the main coat. Not perfect, but every little bit helps...
Yeah, coatings can be a real headache, especially if you’re dealing with older roofs or wild weather. I’ve lost count of how many times I’ve watched a “10-year” coating start peeling after just a couple seasons. You’re right about the patch jobs—sometimes that’s all you can do until you’re ready for a bigger fix. I’ve found that prepping the surface is half the battle, but even then, it’s not foolproof. Metal’s tempting, but those upfront numbers are tough to swallow. Hang in there... sometimes it’s just about buying time.

I get what you’re saying, but honestly, I think prep is more like 80% of the battle. If there’s any dust, chalking, or old coating left, that new stuff just won’t stick right. Sometimes I’ll even do a test patch just to see if it bonds. Admittedly, it’s a pain and doesn’t always guarantee long life, but in my experience, skipping even one cleaning step makes things peel way faster. Maybe it’s overkill, but I’d rather spend extra time up front than redo the whole thing next year.
I hear you on the prep, but honestly, I’ve had coatings peel even after spending hours cleaning and scraping. Sometimes I think it’s just the product or the weather—like, if it’s too humid or the sun’s beating down, nothing seems to stick right. I switched to a white elastomeric coating last year, did all the prep, and still got some flaking by spring. Makes me wonder if these coatings are just a short-term fix no matter how careful you are.
