Home›Roof Cleaning & Moss Removal›Cobham
Thick moss, lichen and algae removed from Cobham roofs using hand scrapers, low-pressure washing or steam, chosen to suit your tiles. Gutters are cleared afterwards and a biocide treatment can be added to slow regrowth.
Roof moss does more harm than spoiling the look of a house. It holds water against the tiles, lifts the edges as it grows, sheds clumps into the gutters and can encourage frost damage through a cold winter. Our roof cleaning Cobham service removes moss, lichen and algae carefully, using a method matched to the material your roof is made from, so the tiles are cleaned without being harmed.
Moss removal usually starts with hand scraping, using specialist made-to-measure tile scrapers that fit the profile of your tiles and lift the moss out of the joints. Depending on the roof, we then use low-pressure washing or roof steam cleaning to remove remaining growth and staining. We never blast tiles with high pressure, which can strip the surface and force water underneath. Once the roof is clean, we clear the moss that has fallen into the gutters, and we can apply a biocidal treatment that slows the return of moss, algae and lichen for longer-lasting results. Throughout, we take care not to disturb ridge tiles, flashings or the leadwork around chimneys.
Cobham has the perfect recipe for roof moss. The River Mole and its water meadows keep the air damp, especially on still autumn and winter mornings, while tall trees in many gardens throw roofs into shade for most of the day. Moss spores thrive on shaded, slow-drying slopes, so north-facing roofs and those beside woodland or the river tend to be carpeted within a few years of their last clean. Overhanging branches also drop organic debris that holds moisture on the tiles.
The town’s mix of roof coverings means one approach does not suit every house. Older properties in Church Cobham and Street Cobham often have clay plain tiles, which are textured and hold moss tightly in the overlaps but can be fragile if handled carelessly. Many 1960s to 1990s houses across KT11 have concrete interlocking tiles, which grow heavy moss cushions but are fairly robust. Larger new homes around Fairmile and Stoke d’Abernon may have slate or high-end clay roofs, where steam cleaning is often the gentlest choice.
Moss removal has a knock-on benefit for gutters, too. On roofs with heavy growth, moss is the biggest single cause of blocked outlets and downpipes around Cobham, so cleaning the roof often solves a recurring gutter problem. We work throughout the KT11 postcode, including Downside, Church Cobham, Stoke d’Abernon and the homes out towards Fairmile Common, and we always finish by clearing the gutters of anything that has come down from the roof.
Each roof is assessed first, because the right method depends on the tiles and the type of growth.
We look at your roof from photos and on site, identifying the tile type, how heavy the moss and lichen are, and any loose or broken tiles you should know about before cleaning starts.
Made-to-measure scrapers that match the tile profile lift moss from the surface and overlaps. This removes the bulk of the growth while keeping pressure on the tiles to a minimum.
Remaining moss, algae and staining are removed with low-pressure washing or roof steam cleaning, whichever suits your tiles. No high-pressure jets are aimed at the roof covering.
Fallen moss is cleared from gutters and downpipes, the ground is tidied, and a biocide can be applied to the clean roof to slow the return of moss, algae and lichen.

A little moss is normal on an older roof, but these signs suggest your roof is due a proper clean:
Dealing with moss before it gets thick reduces the strain on your tiles and keeps gutters flowing through the wetter months. Spring and early autumn are good times to book, when the weather is mild and moss lifts most easily, though we can clean roofs at most times of year.
Roof cleaning is quoted per property, because roofs vary so much in size and condition. We consider:

High-pressure washing can strip the surface from tiles and force water under them, so we do not use it on roofs. We rely on hand scraping, low-pressure washing and steam cleaning, choosing whichever is gentlest and most effective for your particular tiles.
A lot of Cobham is shaded by mature trees and sits close to the River Mole, so roofs stay damp for long periods. Moss loves cool, moist, shaded surfaces, which is why north-facing slopes and roofs near woodland or the river tend to be the worst affected.
Yes, but older clay tiles need a careful touch. We use scrapers shaped to the tile and keep pressure low, and steam cleaning is often a good choice. If we spot cracked or slipped tiles, we will let you know so you can arrange a roofer if needed.
That depends on shade and surroundings, but applying a biocide after cleaning makes a big difference by slowing new growth. Roofs under heavy tree cover will regrow sooner than open, sunny ones, and trimming back overhanging branches also helps the roof dry faster after rain.
Always. Moss removal inevitably sends debris into the gutters, so we clear them and check the downpipes as part of every roof clean. That way you are not left with blocked gutters the next time it rains, and any moss that has washed into an outlet is removed too.
Not necessarily. We need safe access to the house, an outside water and power supply where required, and gates left unlocked. We will let you know when we have finished and can send photos of the cleaned roof, so you can see the difference before you get home.
