- Tried those moss killer granules a couple years back—worked okay at first, but the rain just washed most of it into my gutters. Not sure it was worth the $20.

100% agree. My neighbor keeps blasting his roof every spring and wonders why the moss comes back.“sometimes people get so focused on getting rid of every speck of moss that they forget about what’s causing it in the first place.”
- I’m in the “trim the trees, sweep off the roof, and call it good” camp. Less mess, less money, and my shingles are still hanging on after 18 years.
- Soft wash is tempting, but I’m not climbing up there unless I have to. If it gets really bad, I’ll pay a pro—cheaper than new shingles.
I’ve seen folks spend a fortune on treatments year after year, but honestly, half the battle is just keeping the roof clear and letting it dry out. I’m with you—tree trimming and regular sweeping go a long way. The only time I call in a pro is if there’s visible damage or it’s gotten slippery up there. Not worth risking a fall for a bit of moss.
I totally get where you're coming from—sometimes it feels like the industry pushes all these expensive treatments when a lot of moss and debris issues just come down to shade and moisture. Regular sweeping and pruning trees nearby really do make a difference, especially if you’re in a wetter climate. That said, I do think folks sometimes underestimate how fast moss can damage certain roofing materials, especially wood shakes. I’ve seen cedar roofs rot out in less than a decade because folks waited too long. If you’ve got a steep pitch or a bunch of valleys, I’d rather pay someone than risk it myself... but for a single-story with easy access, I’m all for DIY with the right safety gear.
I hear you about moss on cedar roofs—it’s no joke how quickly it can take hold. I used to think a little green was just cosmetic until I had to replace a few warped shakes on my old garage. That was a wake-up call. On my main house, the pitch is pretty gentle, so I’ve been able to keep up with things myself—just a sturdy ladder, some grippy shoes, and a soft brush. Still, every time I’m up there, I wonder if it’s worth the risk as I get older.
Out of curiosity, has anyone tried those zinc or copper strips at the ridge? A neighbor swears by them for keeping moss at bay, but I’ve heard mixed reviews. Wondering if they’re actually worth it or just another “miracle” fix that doesn’t hold up.
