That’s interesting about the reflective coating peeling up—makes me wonder if some brands just don’t hold up in certain climates. I’ve got a patch of roof that’s always shaded by a big maple, and yeah, it stays cooler but I’m constantly fighting moss. Have you ever tried any of those zinc or copper strips to keep the moss down? I’m tempted, but not sure if they actually work or just end up looking weird after a while.
Funny you mention those strips—I’ve seen a few roofs with zinc or copper up near the ridge, and honestly, they don’t look too bad from the ground unless you’re really staring. I’m curious though, have you noticed if the moss is worse on certain sides of your roof? Sometimes it’s just that combo of shade and moisture that makes it relentless. I do wonder if those strips actually keep working long-term or if they just slow things down for a bit. Ever tried just brushing the moss off, or does it come right back?
Yeah, I’ve noticed the north side of my roof is always the worst for moss—guess it’s just shadier and stays damp longer. I put up some zinc strips a few years back, and honestly, they seemed to help at first, but after a couple seasons it felt like the moss was creeping back in spots. Maybe it’s just not strong enough if you’ve got a lot of tree cover? I tried brushing it off once, but it was back by the next spring, almost like it never left.
Has anyone tried just letting it be? I’ve read that a little moss isn’t always a big deal unless it’s really thick. But then again, I worry about it lifting shingles or holding moisture. Curious if anyone’s had luck with more “green” methods—like vinegar sprays or just improving airflow instead of chemicals or metals. Wondering if that’s wishful thinking or if it actually works long-term...

I hear you on the moss—my north side is always green, too. I’ve tried the vinegar thing, but honestly, it just made the roof smell like salad for a week and the moss didn’t care. I get wanting to avoid chemicals, but in my experience, airflow and sunlight make the biggest difference. I trimmed back some branches last year and it helped more than anything else I’ve tried. Letting it be is tempting, but when it gets thick, I’ve seen it start to curl up shingles and trap water. Not worth the risk, especially if you’re on a budget and don’t want to deal with repairs down the line.
I’ve fought that moss battle too. North-facing roof, lots of trees, always damp. I tried the zinc strips last fall—wasn’t a miracle, but I’m seeing a little less green now. Trimming branches definitely helped more than any spray or homemade mix for me.
