I’ve had similar luck with zinc strips—they help, but moss still creeps back, especially on the north side where it never dries out. Tried a couple “eco-friendly” sprays too, but it’s true, you end up needing to reapply every year or two. Not sure the cost is worth it long-term. I’ve been tempted to just pay for a pro cleaning once every few years and call it good, since I’m not keen on hauling debris off the roof myself either. The flower bed mess is real... half the time I feel like I’m just moving needles from one problem spot to another.
Yeah, I totally get what you mean about the moss coming back, especially on the shady side. Even with zinc or copper, it’s like a never-ending battle. Have you noticed if certain times of year are worse? I’ve seen some folks swear by just sweeping debris off every couple months, but honestly, that sounds like a pain—especially if you’re worried about crushing plants below. Do you think pro cleanings actually last longer, or is it just less hassle? I’m always torn between spending the money and risking life and limb up there myself...
Spring and fall are always the worst for moss around here—seems like the damp just wakes it up. I’ve seen pro cleanings last a bit longer, but honestly, it’s mostly about consistency. If you’re not a fan of ladders (or gravity), paying someone is a lot less stressful. I’ve tried the DIY route and ended up with more moss in my hair than off the roof...
I hear you on the moss—Pacific NW here and it’s like clockwork every year. I’ve tried both ways, but honestly, if you’re comfortable on a ladder and have a decent roof pitch, DIY isn’t that bad. I use a long-handled brush and some moss killer spray, just takes patience and a dry day. That said, if your roof’s steep or you hate heights, paying someone is worth every penny. The trick is staying on top of it before it turns into a carpet up there...
Yeah, I learned the hard way what happens when you ignore moss for a couple seasons—my roof looked like it belonged in a Hobbit movie. I’m not exactly afraid of heights, but after one too many close calls with slippery shingles, I decided my pride wasn’t worth a broken leg. Now I just budget for a pro every spring. Costs more, but at least my neighbors stopped betting on when I'd fall off...
