Clearing roof mess: DIY or hire a pro?

Copper strips are a mixed bag in my book. I’ve seen ‘em slow down moss a bit, but in our climate (I’m up in the PNW too), they just can’t keep up with all the moisture. Folks sometimes expect a miracle, but it’s really more about keeping debris off and staying on top of cleaning. And yeah, flashing is sneaky - one tiny spot missed and suddenly you’re dealing with ceiling stains or worse. Been there more than once...

I tried the copper strips on my place last fall - honestly, I was hoping for a bigger difference. Moss still crept back after a couple months, especially on the north side where it never really dries out. I’m not convinced they’re worth the hype, at least around here. Ended up spending more time up there with a broom than I expected. And yeah, flashing... I thought I could just patch a corner myself, but missed a tiny gap and wound up with a damp spot in the guest room ceiling. Lesson learned: sometimes DIY is more headache than it’s worth.

Copper strips are one of those things that sound great in theory, but in practice... yeah, not always a miracle cure, especially if you’ve got heavy shade or a north-facing roof. Moss is stubborn stuff. I’ve seen folks spend a weekend up there scrubbing, only for it to creep back by spring. And flashing - man, even the tiniest gap can turn into a real headache. I get the appeal of DIY, but sometimes chasing leaks feels like playing whack-a-mole. Some jobs just aren’t worth the stress (or the soggy ceilings).

sometimes chasing leaks feels like playing whack-a-mole. Some jobs just aren’t worth the stress (or the soggy ceilings).

That whack-a-mole feeling is way too real. I thought I’d be clever and tackle my own moss problem last fall - north-facing roof, lots of trees, so it’s basically a spa day for moss up there. I read all about copper strips and figured, “How hard can it be?” Well, after a Saturday balancing on a ladder with a drill in one hand and a strip of copper in the other, I realized the answer: harder than YouTube makes it look.

The thing is, the moss did die back a bit, but not everywhere. The shaded corners just laughed at my efforts. By spring, it was like I’d never bothered. And then there’s the flashing... I tried patching a tiny gap myself with some sealant. Looked fine until the next big rainstorm, when water found its way in anyway. Ended up with a brown spot on my ceiling and a lot of regret.

I get why people want to DIY - costs add up fast if you call in pros for every little thing. But after that mess, I’m starting to think some jobs are better left to folks who do this every day. Especially anything involving heights or potential leaks. My neighbor tried to fix his own flashing last year and wound up slipping off the roof (he’s fine, but his pride took a hit).

If you’re dealing with heavy shade or an older roof, those “miracle” solutions don’t always cut it. Sometimes it’s just ongoing maintenance or biting the bullet and hiring someone who knows what they’re doing. At least then you can blame them if your ceiling gets soggy...

I hear you on the copper strips - those things seem like magic on paper, but real life isn’t quite so tidy. I tried scrubbing moss off my parents’ old composite shingles last year (Pacific Northwest, so it’s a green carpet up there half the year). Even after a couple weekends and a “safe” moss killer, it just came right back in the shady spots.

Honestly, patching flashing is where I draw the line too. It’s one thing to sweep debris or clear gutters, but once water’s getting in, the stakes feel way higher. I’ve seen how a tiny missed spot can turn into ceiling stains or, worse, rot. Sometimes paying for a pro is just buying peace of mind… and keeping your Saturday afternoons dry.

Yeah, moss up here is relentless. I’ve seen folks dump all sorts of “miracle” stuff on their roofs and it just laughs and comes back. As for flashing - once you’re messing with that, it’s not really a weekend warrior job anymore. I’ve tried patching a spot and ended up chasing leaks for months. Sometimes you just gotta know when to hang up the caulk gun and call in backup... unless you like surprise water features in your living room.

- Moss is a beast, no doubt. Seen it chew through “miracle” sprays and powders like nothing. Up here, it’s just part of the deal - constant battle, never really a win.
- About flashing repairs:

“once you’re messing with that, it’s not really a weekend warrior job anymore”

In short: moss is a losing game but manageable with elbow grease. Flashing is where DIY gets risky fast. Sometimes the best tool is knowing when to call it.

- Moss is relentless, yeah. I’ve tried every “guaranteed” treatment - most just lighten the green for a few months. Up here in the PNW, it’s like a subscription service for roof gunk.
- Flashing’s the real trap. I once thought I could just “tuck in” a bit of new metal and call it good. Ended up with a slow leak that took out half my bedroom ceiling before I even noticed. Lesson learned: water always wins if you give it a chance.
- Quick patches are tempting, especially when money’s tight, but honestly, half the time they’re just kicking the can down the road. Had a neighbor who “fixed” his own vent boot - three months later, mold city.
- Moss removal, though? If you’re careful and don’t mind getting dirty, it’s doable. Just don’t get cocky on a wet roof... hospital bills cost more than hiring someone for an hour.
- Contractors can be hit or miss. I always ask around the neighborhood before picking anyone - reviews online only tell half the story.
- In my experience: moss is annoying but manageable; flashing is where things get expensive if you mess up. Sometimes paying for peace of mind is worth it.

- Moss: I just scrape it off with a broom every spring. Tried sprays, but like you said, it’s back by fall.
- Flashing: Don’t mess around - if you’re not sure, pay someone. I learned the hard way after a “quick fix” led to a soggy attic.
- DIY is fine for moss if you’re careful. Anything involving leaks or flashing, I’d rather fork out the cash than risk more damage.
- Contractors: Word of mouth beats online reviews every time, at least around here.
- Wet roofs are no joke - almost slid off mine once. Not worth it for a few bucks saved.

I get the appeal of just scraping moss off, but honestly, I’ve seen way too many roofs where that quick fix just led to shingle damage over time. Around here (Pacific NW), the moss is relentless. Has anyone actually had luck with those zinc strips long-term, or is it just another “temporary” solution?

Clearing roof mess: DIY or hire a pro?

Man, moss in the PNW is a whole different beast. I hear you about the temptation to just scrape it off - I've done that in the past, and yeah, it looked better for a bit, but I ended up with a few shingles that never quite sat right again. Learned the hard way that being too aggressive with a scraper can do more harm than good, especially if your shingles are already a few years old.

About those zinc strips, I was skeptical at first too. Put them up on my own roof (asphalt shingles, pretty average slope) about six years ago. The first year, I didn't notice much difference, but after a couple of rainy seasons, I could actually see a line where the moss just stopped growing below the strips. It's not a miracle cure - still get some moss on the lower parts and in the shade - but it's definitely slowed things down. I still have to brush off the worst spots every couple years, but it's way less work than before.

One thing I wish I'd known: you really have to keep the gutters clear, or the runoff from the zinc can get blocked and then you don't get the full effect. Also, if your roof's got a ton of nooks and valleys, you might need more than just a strip along the ridge.

I get why folks hire pros, especially if you're not comfortable up there or if your roof's steep. But if you're careful and take your time, DIY is doable - just gotta be gentle and patient. And honestly, sometimes just staying on top of it a little at a time beats waiting until it's a huge job.

Hang in there. Moss is stubborn, but with a combo of zinc strips and regular light cleaning, it's manageable. Just takes a bit of persistence.

I’m with you on the zinc strips - didn’t think they’d do much, but after a couple years I noticed less moss too. Still, I’m not convinced it’s a set-it-and-forget-it thing. I’ve got a low-pitch roof (asphalt, about 15 years old), and even with strips, the shaded side is always a pain. Tried brushing lightly last fall and it helped, but I’m always worried about damaging the shingles.

Honestly, the cost of hiring someone just to clean off moss seems steep for what ends up being a yearly chore. But then again, one slip up there and you’re looking at hospital bills instead of just a dirty jacket...

Has anyone tried those “moss killer” sprays? I see them at the hardware store but can’t tell if they’re worth it or just snake oil. If they actually work without wrecking the shingles or plants below, that might be a decent middle ground.

Moss killer sprays can help, but you’ve gotta be picky. Some are pretty harsh and will stain or even eat at your shingles if you’re not careful. I’ve seen folks accidentally fry their flowerbeds too - windy day, wrong angle, and suddenly the hydrangeas are toast. If you go that route, cover your plants and rinse everything down after. Honestly, nothing beats a gentle hand and patience for the shaded side, but yeah, it’s a pain every year.

I’ve tried a few different moss killers over the years, and you’re right - some of them are way too aggressive for older asphalt shingles. I had a patch go brittle after one application, which was a headache to fix. I’ve started leaning toward manual removal, but it’s slow going and not exactly fun on a steep roof. Has anyone had luck with those zinc or copper strips along the ridge? I’m curious if they actually keep the moss at bay long-term or if it’s just another maintenance myth.

Those zinc and copper strips get hyped a lot, but from what I’ve seen, they’re not a magic fix. They do help slow down moss growth, but only where rainwater actually washes over them. On low-slope roofs or spots that stay dry, moss still creeps in. Plus, if your roof’s already got patches of moss, you’ll need to clean it off first - strips won’t kill what’s already there. It’s more of a preventive thing than a cure, and you’ve still gotta keep an eye out for buildup. Not a total myth, but definitely not a set-it-and-forget-it solution either.

They do help slow down moss growth, but only where rainwater actually washes over them.

That’s been my experience too. I put copper strips on my north-facing roof section, and they definitely helped in the runoff path, but the shaded corners still got mossy. I had to get up there and scrub the worst spots first - kind of a pain, honestly. If you’re thinking about DIY, just be careful with the cleaning part. Slippery shingles and ladders can get sketchy fast. For bigger jobs or steep roofs, I’d probably call in a pro next time.

Copper strips are a solid move, but yeah, they’re not magic for every spot. I’ve noticed the same thing - where the water doesn’t flow, moss just hangs on. Scrubbing those corners is a pain, and honestly, it’s easy to underestimate how slick things get up there. If you’re set on DIY, maybe try a harness or at least some grippy shoes. For anything steeper than a walkable pitch, I’d probably tap out and call someone in too. No shame in playing it safe.

Is it just me or do those “grippy” shoes never feel grippy enough when you’re up there staring at a patch of moss in the corner? I tried the copper strip thing too, and yeah, it helped along the main run but did nothing for the shaded side. Has anyone actually found a way to scrub those awkward spots without feeling like you’re about to star in a slapstick fall video? I keep wondering if there’s some trick with a long brush or maybe a pressure washer from the ladder... but then I start picturing water flying everywhere and me soaked to the bone.

I hear you on the “grippy” shoes - mine felt fine until I hit that north-facing patch behind the chimney. Next thing I know, I’m clinging to the vent pipe like it’s a lifeline. I tried one of those telescoping brushes from the ladder, but honestly, it just made me more nervous. Pressure washer sounded good in theory, but I chickened out after picturing myself sliding off like a cartoon character. In the end, I just did what I could reach and left the rest. Not perfect, but at least I stayed dry and in one piece.

That’s pretty much the story of my first attempt, too. I figured, hey, how hard can it be to sweep off some moss and leaves? Turns out, way harder than expected when you’re up there and realize your “surefooted” shoes are actually just sneakers pretending to be helpful. The north side of my place is always damp, so it’s basically an ice rink half the year. I tried one of those cheap extendable brushes too - felt like I was jousting with my own gutters.

Pressure washer made me nervous. Not even because of slipping (though that’s a real fear), but more about blasting water under the shingles and causing leaks I’d never find until next spring. In the end, I only got about halfway before I called it quits and decided paying someone wasn’t as expensive as a hospital bill.

I get the appeal of DIY, but honestly, roofs are one spot where I’m leaning toward hiring out unless it’s something super minor. Maybe if I had a ranch instead of this steep-pitched roof…
