I was a little nervous about the blue-green stains in my gutters, so it’s good to know that’s just the copper doing its thing.
That copper patina definitely throws people off at first, but it’s actually a good sign your system’s working. I had the same worry when we first put in copper strips up top—looked like something out of a chemistry set for a few months. The splash block idea is solid, especially with edibles nearby. I’ve read mixed things about runoff and veggie gardens, though; some folks say trace metals can build up over time, others think it’s negligible unless you’re harvesting right under the spout every season. Have you noticed any difference in your soil or plants since the stains started showing up?
On the algae front, I get what you mean about moss thinning versus roof stains. In my case, the copper cut down on black streaks but did make the north-facing side look a bit patchy where moss used to be thick. Did you go with full-length copper strips or just smaller tabs? Curious if you saw any difference in coverage or how long it took to see results.

Yeah, I’ve heard the same. I’m a bit cautious since my raised beds are right by the downspout, so I added a cheap splash block just in case. Haven’t noticed any weirdness with the tomatoes or herbs so far, but I do keep an eye out. For the copper, I went with shorter tabs to save money—coverage isn’t perfect, but it’s definitely helped with algae. The moss is patchier now, but honestly, I’ll take that over black streaks any day.
I’ve always wondered about the long-term effects of copper runoff on soil, especially if you’re growing edibles nearby. I get the appeal—those black streaks are ugly and the copper definitely helps—but I’m not convinced it’s totally harmless over a decade or two. Have you ever tested your soil for metals, just out of curiosity? I’ve thought about sending a sample in, but never got around to it. My neighbor swears by zinc strips instead, but I haven’t tried those yet...

I’ve wondered the same thing, honestly. I keep meaning to test my veggie beds since they’re right under the drip line, but it’s one of those “someday” projects. My dad used copper strips for years—he never noticed any issues, but he wasn’t growing tomatoes under the eaves either. Zinc strips are on my radar too, but I’m not convinced they’re totally risk-free. Sometimes it feels like there’s always a tradeoff with these fixes.
I get the concern about metals leaching into the soil. I’ve read mixed things about copper and zinc—some say it’s minimal, others warn about long-term buildup. Honestly, I just scrub my shingles every couple years instead of adding anything new. Less risk, less cost.
