Is Moss Doing More Than Look Untidy?
Moss and algae aren’t just cosmetic — left long enough, they genuinely shorten the life of your roof.
Visible green or black staining
Moss and algae growth is easiest to treat early, before it thickens and starts holding water against the tile surface.
Moss concentrated on shaded slopes
North-facing or tree-shaded roof sections stay damp longer, which is exactly why moss establishes there first.
Gutters filling with washed-down debris
Moss breaking loose in heavy rain is one of the most common causes of a gutter that blocks repeatedly.
It's been several years since the last clean
A roof that hasn't been cleaned in 3–5 years usually has enough build-up to be worth treating before it gets heavier.
Roof Cleaning Services, Fixed Price
Cleaning done properly protects your roof. Cleaning done with a pressure washer can damage it — here’s the difference.
Soft-Wash Moss & Algae Removal
Moss, algae and lichen removed using a low-pressure soft-wash method that cleans thoroughly without stripping the protective surface of your tiles.
Hand Removal & Debris Clearing
Thick moss growth removed by hand first where needed, followed by a soft wash — gentler on older or more fragile tiles than washing alone.
Biocide Treatment
A biocide treatment applied after cleaning to slow moss and algae regrowth, extending the time before the roof needs cleaning again.
Copper / Zinc Strip Installation
Metal strips fitted along the ridge release trace amounts of copper or zinc with every rainfall, inhibiting moss regrowth for years afterward.
Roof Cleaning Across Barnet
Barnet’s genuine green spaces and suburban semi-detached streets shape how often roofs here need cleaning.
Mill Hill & the Hampstead Heath Extension
The mature tree cover around Mill Hill and the Heath Extension near Golders Green means roofs nearby often collect more organic debris and grow moss faster.
Hendon & Golders Green's Mansion Blocks
Larger flat roof areas on mansion blocks collect debris differently to pitched tile — often algae or lichen rather than moss.
North-Facing Roofs
Semi-detached houses across the borough often have shaded north-facing slopes where moss establishes fastest.
Finchley to Edgware
Emergency cover across the full borough, from Finchley and Hendon out to Golders Green, Mill Hill and Edgware.

What Barnet Homeowners Say
Mill Hill · Heavy Moss Removal
“North-facing slope was thick with moss after years of neglect. Explained why they wouldn’t pressure wash it, did a proper soft-wash instead, roof looks brand new without any damage.”
Golders Green · Clean + Copper Strips
“Had the roof cleaned and copper strips fitted at the ridge on the same visit. A year on and there’s noticeably less regrowth than before. Worth the extra.”
Finchley · Standard Clean & Gutter Clear
“Quoted over the phone, gutters were full of washed-down moss from a previous clean elsewhere and got cleared as part of the job. Straightforward and fairly priced.”

Roof Cleaning in Barnet, Answered
No, and we won't do it. High-pressure water can strip the protective granules off concrete and asphalt tiles, force water up under the tile laps, and damage older or more brittle materials. We use a controlled soft-wash method instead, which cleans just as effectively without the risk.
It depends heavily on your roof's aspect and surroundings — a shaded, north-facing roof under trees may need cleaning every 2–3 years, while a sunny, exposed roof might go 5 years or more. We'll give you an honest estimate for your specific property.
Done properly with a soft-wash method, no — most manufacturers actually recommend periodic cleaning. It's aggressive pressure washing that risks damage and potential warranty issues, which is exactly why we don't use it.
A standard insulated panel roof caEventually, yes, unless the conditions that caused it change — shade and damp will always favour moss. A biocide treatment or copper/zinc strips fitted at the ridge both meaningfully slow regrowth, so the roof stays cleaner for longer between treatments.n often be completed in 1–2 days. A full tiled roof conversion with plastered ceiling typically takes longer, usually 3–5 days depending on size and whether reinforcement work is needed.
Yes. Moss and debris dislodged during cleaning often ends up in the gutters, so a gutter clear-out is included as standard, not charged as an extra.
