A gutter has one job: to carry roof water to a downpipe and away from the walls. Leaves, moss washed off the tiles, grit from the roof surface, seeds and the odd bird's nest all end up in it. Left alone, that mix packs into a wet mulch that blocks the outlet, holds water against the fascia (the board the gutter is fixed to) and grows plants of its own. Cleaning costs little next to other roofline work, and it is the job most often put off.
This guide covers how often a gutter needs clearing, the two usual methods, what safe access really means, and what we check once the channel is empty and the fittings are visible. It stays with the gutters themselves. If the problem is a pipe that will not drain, our answer on a blocked downpipe covers that, and the wider service is at guttering, soffits and fascias.
What builds up in a Stroud gutter
The mix changes with the street. On a hillside lane lined with beech, sycamore or horse chestnut, autumn leaf fall is the main load, and it arrives in a few weeks. Under conifers the fall is needles, which are fine enough to slip into the outlet and form a plug. On an older stone roof, grit and fragments of weathered stone and moss wash down with every shower. Where the roof is a covering with a gritted surface, such as some felt, the loose granules collect in the same place.
Why it matters
Debris does three kinds of harm. It slows the flow, so the gutter fills and spills over the front, soaking the fascia and wall below. It holds water, which rusts cast iron from the inside and sags an overloaded plastic run on its brackets. And it gives seeds a damp bed: a sycamore seedling in a gutter is a familiar sight, and its roots work into the joints.
Moss and plant growth also hide faults. A gutter that never gets cleaned cannot be inspected, so a cracked joint or a loose bracket sits unnoticed until the next storm shows it up.
How often to clear them
Every house differs, so what follows is a way of reasoning rather than a fixed rule. As a starting point, clear every gutter once a year, in the weeks after the leaves are down. Then adjust for the site.
Under and near trees
Overhanging branches mean more than one visit. A clear-out when the leaves have fallen, and another look in late spring when blossom, catkins and seed cases drop, keeps the channel working. Evergreens shed all year, so a roof under conifers is worth checking after any storm that has brought branches down.
Open sites
A house with no trees nearby may only need a yearly visit. The debris is mostly roof grit and moss, and it builds slowly. Roofs that have just been cleaned of moss are the exception: everything that came off the tiles lands in the gutter, so look at the channel straight after.
Signals that it is overdue
Water spilling over the front lip in rain, a dark tide mark down the wall, a downpipe that gurgles or stays dry in a downpour, grass or weeds sprouting from the gutter edge, and staining on the fascia are all signs. If you can see plants from the ground, the channel is well past due.
Keep a note of the date. A gutter that was cleared last October and is overflowing in March tells you the run needs attention more often, or that something else is wrong with it.
Cleaning by hand
Hand cleaning is the method that works on any gutter, and it lets you feel as well as see what is happening in the channel. The tools are few: gloves, a small plastic scoop or trowel, a bucket on a hook and, on a ladder, a stand-off arm so the ladder bears on the wall rather than the gutter.
The sequence
Start at the end furthest from the outlet and work towards it, so you are always pulling debris along a clear stretch rather than burying the outlet. Scoop the bulk into the bucket. Do not tip it down the downpipe or onto the lawn under the run; a downpipe plugged with wet leaves is a bigger job than the gutter was.
Once the bulk is out, flush with a hose from the high end. Watch the water travel. It should run steadily to the outlet and drop into the pipe. If it pools along the way, the gutter has lost its fall, which is a repair question rather than a cleaning one; our leaking gutters guide explains fall, joints and sag.
What not to use
Avoid metal tools on cast iron or coated aluminium, which scrape off the protective finish. Avoid pressure on old plastic, which can crack it. And never lean on a gutter to reach further, because a bracket that seems firm from below may be screwed into soft timber.
Vacuum cleaning and when it makes sense
Gutter vacuum systems use a powerful suction unit at ground level and a long pole with a head that hooks over the gutter. The operator can see the channel through a small camera mounted on the head or by watching the debris go up the tube. For tall or awkward houses it avoids working from a ladder at all.
Where it works well
Loose, dry material such as leaves, twigs, needles and seeds comes out cleanly. A pole system is quick on long runs, and it can reach gutters over a conservatory, an extension roof or a porch that would be hard to ladder safely.
Where it struggles
Wet, compacted mulch, moss and silt can block the nozzle, and a heavily clogged run may need loosening by hand first. A vacuum also cannot touch the things that matter most for a repair: the joints, the brackets, the condition of the fascia and the line of the fall. It clears a channel, but it does not inspect it.
Our approach
We use whichever method suits the gutter. Where the roof needs a scaffold or tower for other work, the gutter is cleaned by hand while we are there, since the best view of the joints is from the same height as the gutter. For a plain clear-out at a reachable height, either method will do the job.
Cleaning shows you the gutter. Inspecting it is a separate look, and it is worth asking for both.
Working at height without an accident
Gutter cleaning is a typical reason to be up a ladder, and a ladder is a poor place to spend an afternoon. It suits short, light tasks. Where the job cannot be done safely from one, it should be done from something more stable.
If you do it yourself
Set the ladder on firm, level ground at a safe angle, and have someone foot it. Keep your weight within the width of the stiles and your hips between them; if you cannot reach, come down and move it. Do not stretch sideways, do not carry a full bucket up the rungs and do not climb a wet ladder in the rain. A stand-off bracket keeps the ladder clear of the gutter itself.
Plastic gutters are not a support. Even a fascia that seems sound may be rotten behind a coat of paint or a plastic covering, so the ladder should rest on the wall, not on the roofline.
When to hand it over
Anything above ground floor height with a pitched roof, a steep drop below, a conservatory or lean-to in the way, or a slope that makes siting a ladder difficult is better done from a scaffold tower or a platform. Many of the houses we visit on hillside plots have uneven ground at the front, which is exactly where a ladder is least stable, so the access is worked out and priced before anyone climbs anything.
MyBuilder's 2026 price guide puts roofline scaffold at £20 to £40 per m², a national range that is useful for comparing a one-off cleaning with a job that includes repairs.
What to check while the channel is empty
With the channel empty, the faults that lead to leaks and rot show themselves, and many take a minute to spot.
The run itself
Look along the line for dips. Water that stays in the bottom after a flush shows a sag. Look at each joint: staining below it, a crack in the seal or a lip that has opened are all signs of a weeping joint. Check the rear face against the fascia for rust on iron or splits on plastic.
Brackets and fascia
Count the brackets and see that none is missing, bent or pulling away. Push gently on the fascia behind: soft, flaking or dark timber means the boards are failing, and that is a bigger job than the gutter. Our downpipes and drainage guide covers the next link in the chain, the pipes and shoes that take the water down.
The roof edge
From a good vantage point you can also see the first courses of the roof: slipped or broken tiles at the eaves, a failed felt drip or a row of dislodged slates. These are cheap to fix now and expensive when water has been running behind the fascia for a season. Ask too whether the gutter is large enough for the roof it serves, since a channel that overflows in every downpour, even when clean, may be undersized or lack a second outlet.
Photographs of your own gutters and roof edge go with the survey notes, so you see what we saw before any repair is priced.
Gutter guards, birds and the things that are not leaves
Mesh or brush guards promise to keep debris out. They can help on a run beneath a single tree, but a guard does not remove the need to look: fine seeds and needles can still lodge on top of mesh, and a blocked guard hides the problem from view. If you are weighing one up, see our guide to gutter guards before you buy.
Nests and wildlife
Birds and other animals do sometimes nest in or behind gutters and in the eaves. Active nests and bats are protected, so if you find either, stop work and take advice before disturbing them.
Old pipes and unknown materials
Some older rainwater goods are asbestos cement rather than iron or plastic. HSE guidance covers careful handling of undamaged material as non-licensed work, but it should not be scrubbed, scraped or pressure washed. If you are unsure what your gutters are made from, tell us before anyone starts.
What the bill covers
A cleaning visit on its own is a small job, and national cost guides tend to fold it into repair. When the visit leads to a repair, you will get a written quote after the survey, covering access, labour, parts and waste. The 10-year workmanship guarantee on our work comes in writing, and we take away any waste.
If you would like a set of eyes on your gutters, send us a couple of photographs of the lip, a joint and the outlet, plus a note of any trees overhanging the roof.
