Totally agree that prep makes a huge difference. Did you guys use any specific primer or cleaner before applying the elastomeric coating? I've heard mixed things about pressure washing metal roofs beforehand—some say it's essential, others think it can damage the finish. Curious what your experience was with that... Also, did adjusting the slope require much extra work or was it pretty straightforward?

Yeah, that's a tricky one. From what I've seen, pressure washing can be okay if you're careful and use a lower PSI setting. I've seen roofs get damaged when people go overboard with high pressure. Personally, I'd stick with a good cleaner and scrub brush approach—takes a bit more elbow grease but safer overall. Adjusting slope usually isn't too bad unless you're dealing with structural issues underneath...hopefully yours was straightforward.
I get the caution around pressure washing, but honestly, I've had good results with it—just gotta be smart about it. Last summer, we had a metal roof on one of our buildings that was covered in moss and grime. We used a lower PSI setting, kept the nozzle at a safe distance, and it cleaned up nicely without stripping the finish. I'd say it's more about technique and patience than anything else...rushing or using too much pressure is where people usually mess up.
Fair points, but gotta say pressure washing metal roofs still makes me a bit twitchy. Seen too many cases where folks thought they were being careful and ended up with leaks or damaged coatings. Personally, I'd rather stick to a gentle cleaner and soft-bristle brush—takes longer, sure, but less chance of accidentally blasting water under seams or loosening fasteners. Guess it depends how much you trust your aim and patience level...mine's questionable at best, lol.
Haha, totally get you on the patience thing...mine runs out pretty quick too. Last summer I tried pressure washing my metal shed roof—thought I'd be smart and careful—but ended up with water dripping inside for days. Lesson learned the hard way. Your soft-brush method sounds way safer, even if it means spending an extra hour or two scrubbing. Honestly, a little elbow grease beats patching leaks any day. Good call sticking to what works for you...and your questionable aim, lol.
