Haha, wish I'd read this thread sooner. I went straight for the heavy-duty cleaner on mine and ended up with a roof that looks like abstract art... lesson learned. Gentle soap next time, noted.

Haha, you're definitely not alone—seen plenty of roofs turned into accidental masterpieces over the years. Good news is, metal roofs are pretty forgiving, so a gentle soap wash next time should smooth things out nicely. If it's really noticeable, you could always embrace it as a unique feature... call it custom patina?
Curious though, did you notice any changes in how water runs off after your cleaning adventure? Sometimes heavy cleaners can alter the surface a bit, affecting drainage or even noise during rain.
Had a tenant once who did something similar—ended up with streaks all over the roof. Honestly, didn't notice much difference in water runoff, but weirdly enough, birds seemed to avoid landing there afterward. Ever notice anything like that?
Interesting observation about the birds, but honestly, I've never seen anything like that. Had a similar roof issue at one property—tenant tried some DIY coating and ended up with streaks everywhere. Didn't notice any bird behavior changes, though. Maybe it depends on the type of coating or metal? Or could it just be coincidence...? Either way, I'd be cautious about assuming it's bird-proof just yet.
"Either way, I'd be cautious about assuming it's bird-proof just yet."
Yeah, gotta agree with this. Seen plenty of roofing products claim they're bird-proof or pest-resistant, but in practice... birds seem pretty adaptable. Had a customer swear by copper flashing once, saying it kept pigeons away—until they nested right on top of it a month later. Could be the coating or maybe just dumb luck, but I'd hold off celebrating until you've seen it in action for a while. Just my two cents.
