How I Clean Gutters Properly (And When I’d Tell a Customer to Call a Pro Instead)

Gutter cleaning is one of those jobs that looks simple from the ground and gets a lot more complicated once you’re actually up there. I’ve cleared gutters on everything from single-storey bungalows to tired old two-storey houses with overhanging trees and roofs thick with moss, and the job is never quite as straightforward as “scoop the leaves out.” After enough of these, you start to notice the patterns: which houses are quick, which ones eat your whole morning, and which ones I won’t touch without scaffolding or a second pair of hands.

This isn’t a generic “how to clean your gutters” piece. It’s what I’ve actually learned doing the job, what I use, what I’d tell you to avoid, and where I draw the line between a DIY job and a “ring a professional” job.

Bungalows vs Two-Storey Houses: Not the Same Job

The single biggest factor in how easy a gutter clean is going to be isn’t how dirty the gutters are, it’s how high they are.

On a bungalow, you’re generally working with a standard step ladder or a short extension ladder, solid footing, and you can reposition every few feet without much fuss. It’s manageable, and a competent, careful DIYer can do it themselves with the right gear.

On a two-storey house, everything changes. You need a proper extension ladder, often a 3-section one to get the reach, and that brings its own problems: stability on uneven ground, the ladder flexing more the higher you go, and a much higher consequence if something goes wrong. I’ve worked on dual-storey properties where the only safe access was round the back through a narrow side return, which meant carrying a long ladder through a gap it barely fit through. That’s the kind of job where I’d always question whether it’s worth doing yourself, simply because the margin for error gets a lot smaller the higher you go.

If you’re on a bungalow, this is a realistic DIY job. If you’re on a two-storey house, especially with restricted access, I’d think hard before doing it yourself.

Moss Is the Real Enemy, Not Leaves

Most people picture autumn leaves when they think about blocked gutters, but in my experience moss is what actually causes the worst jobs. Leaves blow out or wash through relatively easily. Moss doesn’t. It builds up in thick, compacted mats that hold water, sit on the gutter and roof edge, and slowly work their way into every joint and downpipe.

North-facing roofs are consistently the worst for this. They get far less direct sun, stay damp for longer after rain, and that’s exactly the environment moss thrives in. If a customer tells me their gutters “just need a quick clean,” and I can see a north-facing roof from the van, I’m already mentally planning for a longer job than they’re expecting.

If you’ve got a north-facing roof, or anything with overhanging trees, check it more often than the south-facing side of the same house. It will need it.

Plants and Growing Life: Deal With Them First

This sounds like a small detail, but it’s one of the things I always prioritise: any plants or weeds actually growing in the gutter need to come out before anything else. It’s tempting to scoop the loose debris first and leave the stubborn bits for later, but I do it the other way round.

Growing plants mean roots, and roots mean they’ve had time to get into joints, sealant, and sometimes even start working into the fascia behind the gutter. Leaving them until last means you’re working around live root systems while you’re trying to clear everything else, and you risk snapping growth off above the root rather than clearing it properly, which just means it grows back faster. Get the rooted stuff out first, then move on to the loose debris and silt.

What I Use: Tools and PPE

I keep this kit simple and durable rather than buying gimmicky gutter-clearing tools that promise to do the job from the ground. In my experience, nothing beats actually being up there and doing it properly.

For access:

• A good quality extension ladder, the right length for the property, with stabilisers where the wall allows
• A ladder standoff/stay to keep weight off the actual guttering, never lean a ladder directly against a fascia or gutter

For PPE:

• Thick, waterproof gloves are the one piece of kit I wouldn’t skip. Gutter debris is a mix of wet leaf mulch, moss, grit, and often bird mess, and it’s genuinely unpleasant to deal with bare-handed or in thin gloves that soak through in minutes. I look for gloves with a textured grip and a cuff long enough to stop debris running down inside them when you’re scooping
• Eye protection, especially when clearing downpipes where you can get a face full of backed-up water without warning
• A dust mask for dry, dusty roofs, which sounds unnecessary until you’re clearing a gutter that hasn’t been touched in three years

For the actual clean:

• A small hand trowel or scoop for the bulk debris
• A stiff brush for the final pass along the gutter base
• A bucket with a hook that clips onto the ladder, so I’m not climbing up and down constantly
• A hosepipe to flush the gutter through and check the flow once it’s clear, this is the step a lot of people skip, and it’s the only real way to know the downpipes aren’t still partially blocked

Why I Prefer This Set-Up Over the Alternatives

I’ll be upfront here, I don’t use the gutter-clearing vacuum attachments that clip onto a pole and let you do the job from the ground. They’re marketed heavily, and for a very light, regular clean on a single-storey property they can be fine. But for anything with real moss build-up or compacted debris, they don’t have the suction or control to actually shift it properly, and you end up going back over the same section repeatedly without much to show for it.

I’d rather be up the ladder doing it by hand with a scoop and a brush. It takes longer per gutter run, but it’s a proper clean rather than a surface pass, and I can see exactly what’s going on with the joints, brackets, and downpipes while I’m up there, which a pole tool will never show you.

When I’d Tell a Customer to Call a Professional Instead

I think it’s worth being honest about this, because plenty of guides will tell you any job is a DIY job if you just buy the right tool. This one isn’t always.

I’d call in a professional, or tell a customer to, when:

• The property is two-storey or more, and ladder access is genuinely difficult or restricted
• There’s no safe, stable, level ground to set a ladder up on
• The gutters haven’t been cleaned in several years and are heavily compacted, this is a longer, messier, heavier job than it looks from the ground, and not a quick weekend task
• You’re not confident on a ladder. This sounds obvious, but it’s the single biggest factor in whether this job is safe to do yourself
• You’re working alone with no one aware you’re up there. Even on a straightforward bungalow, I wouldn’t recommend doing this completely solo with nobody knowing

If none of that applies to you, a bungalow or easily accessible single-storey section is a genuinely manageable DIY job with the right gloves, a stable ladder, and a bit of patience.

A Quick Run-Through of How I Actually Do It

1. Check access first, walk the full perimeter of the gutter run before climbing anything, and identify any sections with plant growth or heavy moss so I know what I’m dealing with
2. Set the ladder up with a stay/standoff, never resting directly on the gutter
3. Clear any rooted plants or weeds first
4. Scoop out the bulk debris into the bucket, working in short sections so I’m not overreaching
5. Brush the base of the gutter to clear the fine silt that builds up underneath the leaf debris, this is the stuff that causes slow drainage even when the gutter looks “clear”
6. Flush the run through with a hose, watching the downpipe outlet to confirm it’s running freely
7. Move the ladder and repeat, section by section, rather than trying to reach too far from one position

It’s not a complicated process, but doing it properly, in the right order, with the right kit, is what separates a gutter clean that actually lasts until the next season from one that needs doing again in six weeks.
