Gutter brush vs gutter guard
Updated: 23 October 2026
You are choosing a gutter brush vs gutter guard because both are sold as the end of cleaning. A brush fills the channel with bristles. A mesh guard sits over the opening. They fail in different ways, and some gutters should get neither until they are cleared and measured. Rankings of the rolls we kept are on the [gutter brush comparison](/hub/diy-supplies/gutter-brush). Hedgehog’s guarantee and BDC Magazine’s May 2023 account were read on 21 October 2026. We did not run a flow bench. If you buy through our links, we may earn a commission at no extra cost to you.

What each product actually blocks
A gutter brush and a hedgehog are the same object in UK shops: a flexible core with plastic bristles that sits in the gutter so rain can pass and broad leaves stay on top, where wind can move them. Annual Cleaning Solutions’ guide puts the brush ahead for large leaves and for a roll you can lift out again, and behind on fine debris and moss. It puts mesh ahead on finer litter, then notes that moss can mat on the mesh and shed water over the gutter edge.
Cannins, a contractor writing in February 2025, is blunter. Brushes and mesh both let needles, grit, and moss through, and silt still forms underneath. Hedgehog’s own guarantee excludes silt and seedlings, and it still says you clean the brush where trees and moss drop in. If the fall is needles, seed, and moss flour, neither product earns a fit-and-forget sentence.
What happens to the water
The brush occupies the channel. The mesh occupies the top. That geometry is the flow question, and it is separate from whether leaves stay out. Approved Document H, for England, sizes certain level half-round gutters in Table 2 without any insert. A 100 mm gutter and a 63 mm outlet are shown there for 37 m² and 0.78 litres per second, under the conditions the table states. A brush is not part of that guidance, and fitting one does not approve the gutter.
BDC Magazine in May 2023 reported trials, described in the article as BRE-style, in which a brush cut a stated 120 litres per metre baseline to 60. The magazine argues that mesh on top impedes flow less than a brush in the channel. We do not hold the BRE paper, so this page does not say BRE proved a winner. A cover that sheds water over the front lip has not preserved the flow.
When to buy neither yet
Buy neither while the gutter is full of silt, while you have not measured the inside width, or while the run is a valley or a box gutter behind a parapet. A gutter that is already failing in ordinary rain needs a clear-out and, often, a larger outlet or a second drop before it needs a cover.
A 150 mm gutter and a valley are outside the 100 mm rolls in our brush table. If water is staining the wall, if the fascia is rotten, or if the roof may be asbestos cement, the next step is a competent person, not a tighter mesh. Fitting a brush after the gutter is clear is on how to fit a gutter brush.
A conditional recommendation
Choose a brush when the debris is broad leaves, you have measured an inside width near the 90 mm example in the Hedgehog guide, and you will still look in the gutter. The roll can come out again. Fines, moss, and seedlings are outside the Hedgehog guarantee, and the BDC report says the waterway gets smaller.
Choose a mesh conversation when the litter is finer than a broad leaf and you accept a cover that can mat with moss and overflow at the lip. Do that shopping on the gutter protection comparison.
Choose neither when the gutter is undersized for the roof, already silted, or out of reach on a roof you should not be brushing. A pole that scrapes from the ground empties a gutter once. It does not settle this fork.
Common questions
Are a gutter brush and a hedgehog the same thing?
In UK shops, yes. Both names mean a bristled roll on a flexible core that sits in the gutter. A brush on a sectional pole is a different tool: you clean with it and then store it. This page is about the roll you leave in, set against a mesh cover over the opening.
When is a mesh cover the better fork?
When the debris is finer than broad leaves and you accept the cover’s own failure. Annual Cleaning Solutions puts mesh ahead on fine litter and warns that moss can mat on top and shed water over the edge. Cannins says needles, grit, and moss still get through both brush and mesh. Shop the mesh products on the gutter protection comparison, not in this brush table.
Will either stop roof moss?
Plan on no. Hedgehog’s guarantee excludes silt and seedlings, and trade guides say moss passes a brush and can mat on a mesh. Moss on the roof is a roof question. A gutter product does not stop it growing on the tiles, and a mat of moss on a mesh can push rain over the front of the gutter.
What about pine needles?
Needles are the case both trade guides treat as weak for a brush and awkward for a mesh. They are thin enough to pass bristles, and they can thatch on a cover. If pines overhang the eaves, expect to keep inspecting. A hedgehog guarantee that excludes seedlings is the same warning in the maker’s own words.
Should I still look in the gutter once a year?
Yes. Both products are sold with a never-clean story that the maker pages and the contractor guides do not support. Check the outlet and the bay under the trees. Silt and seedlings are outside the Hedgehog guarantee, and Cannins says silt still forms under brushes and under mesh.
