"Honestly, a little elbow grease beats patching leaks any day."
True about avoiding leaks, but honestly, pressure washing doesn't have to be a disaster if you're careful. I've done my metal roof a couple times without issues—just gotta keep the nozzle angled downward and use a lower pressure setting. I get that scrubbing feels safer, but man...my back protests loudly after an hour of that. Maybe worth giving the washer another shot someday, questionable aim and all, haha.
I hear you about the back pain...been there, done that. Pressure washing definitely isn't the enemy if you're careful. I once spent an entire afternoon scrubbing moss off my metal roof by hand—never again. Next time, I angled the washer nozzle downward, dialed down the pressure, and it was like night and day. No leaks, no drama, and my back thanked me later. Maybe your aim isn't as questionable as you think, haha.
"Pressure washing definitely isn't the enemy if you're careful."
Fair point, but a quick heads-up:
- Even dialed-down pressure can strip protective coatings if you're not super careful.
- A gentler alternative I've used is a vinegar-water mix sprayed on, left overnight, then rinsed off—less risky for the roof finish.
- Plus, vinegar's dirt cheap and easy on the wallet...
Just something to consider before you fire up the washer again.
Totally get your point about vinegar being wallet-friendly—I’ve tried that myself. But honestly, I found it a bit hit-or-miss on tougher grime.
"Even dialed-down pressure can strip protective coatings if you're not super careful."
True enough, but if you keep the nozzle at a good distance and angle, pressure washing can still be safe and effective. I've had decent luck using a mild detergent mixed in, too—cuts through stubborn dirt without wrecking the finish. Just gotta use common sense and go easy...
Good call on the detergent—I usually mix in a bit myself. One thing I've noticed though, is that certain detergents can leave a filmy residue if you don't rinse thoroughly enough. Ever run into that issue? Curious what brands you've had luck with...
