Roof Cleaningin Didcot
Didcot has grown in stages, from the old village and Northbourne to post-war estates, Ladygrove and Great Western Park, so its roofs differ by era. We read the covering and the growth, lift the moss by hand and clean to suit.
- Concrete tile roofs cleaned
- Older roofs judged carefully
- Rainwater route left clear
Our method
Every era of roof asks something different so the method changes with it
A clay roof on an older house that has carried moss for years, a concrete roof on a post-war estate with lichen across its profiles, and a newer roof with a light green film are three different jobs. We look at the age, the covering and the growth before suggesting anything, rather than bringing one method to every street.
How the town grew
Older streets and newer neighbourhoods
Didcot has developed over several distinct periods. Older homes remain around the original village and Northbourne, post-war estates followed, and later growth brought Ladygrove and, more recently, Great Western Park. Neighbouring parts of town can therefore have roofs decades apart in age, from clay tiles on older houses to concrete interlocking tiles across the later estates.
Growth follows shade rather than age. Garden trees, close neighbouring houses and north-facing slopes keep some roofs damp after rain, and even a fairly new roof can carry moss along its lower courses and lichen on its profiles. Older roofs often have both, plus earlier repairs and replacement tiles that need to be identified before any cleaning starts.
Concrete tiles
Profiled concrete roofs on the later estates
Concrete interlocking tiles are common on the town's newer homes. As their surface weathers it roughens, holds water and gives moss a foothold, especially in the troughs of profiled tiles and along the lower courses above the gutter. Lichen often appears as yellow or grey spots across the tile faces.
Where the tiles are sound, a carefully controlled low-pressure clean after hand removal can bring back a markedly brighter colour; where they are tired, a gentler soft wash is the better choice.
Reading the roof
Following the pattern of growth
Moss rarely spreads evenly. One slope may be clear while another is thick with growth around the lower courses, beneath a roof window or beside a chimney. We note where it is concentrated and how firmly it holds, so effort goes where it is needed and nothing more forceful than necessary is used on lightly affected areas.
- Thick moss: lifted by hand first
- Light film: low-pressure clean or soft wash
- Lichen: treated, then left to weather
Hidden defects
When cleaning shows what moss was hiding
Dense moss can cover slipped tiles, cracked edges and tired mortar. Once it has gone, those issues are easier to see, and that is useful information rather than damage caused by the clean.
We keep cleaning and roofing repairs separate: we clean and report what we notice, and repairs are left to a roofer, so you know exactly what you are dealing with and nothing is hidden under a fresh-looking surface.
After the clean
Treatment that helps hold growth back
Once the surface is clean, the Chiltern EverGuard™ Treatment is applied as standard. It works into the tile to target spores and lingering growth that cleaning cannot always reach, and it helps reduce how fast moss, algae and lichen re-establish.
Protection typically lasts between 12 and 24 months, depending on shade, surroundings, the covering and maintenance. We apply it in settled, frost-free weather and email to offer a free assessment when the period draws to a close.
Step by step
From roof review to handover
The stages are the same on an older house and a new-build; what changes is the method inside each one.
- 01
Roof review at a free visit
We look at the covering, pitch, condition, growth and access from the ground, using a drone where it adds useful detail and sharing the images with you.
- 02
Method and access explained
Our report and clear quotation set out the combination of hand removal, cleaning and treatment we recommend, and the access we will use, before you commit.
- 03
Hand removal and cleaning
Moss is lifted by hand from access equipment close to the roof, then the tiles are cleaned at the lowest appropriate pressure or soft washed.
- 04
Rainwater route cleared
Gutters affected by the clean are emptied and downpipes checked so loosened moss does not obstruct the drainage, and surrounding surfaces are left tidy.
- 05
Treatment and handover
The Chiltern EverGuard™ Treatment is applied in suitable weather, and the project lead explains what was done and any concerns noticed on the roof.
Expectations
How an older or newer roof will look after
Sound concrete tiles usually show a clear colour change once cleaned, though surface wear from long weathering remains. Older clay keeps its natural variation. Some lichen marks fade gradually after treatment rather than all on the day, and a roof next to trees will green over sooner than one in the open. We tell you at the visit what is realistic for yours.
Why us
Why owners ask us to look at their roofs
Methods for every era
Clay on older homes and concrete on later estates are handled differently, with the method chosen after seeing the roof.
A clear view from above
Where it helps, a drone shows the rear slopes and details you cannot see from the street, with live images shared on site.
Drainage left working
Moss from the clean is removed from gutters and downpipes, so the problem is not simply moved further down the house.
Fully insured
Our operatives are fully insured and work from proper access equipment, never by walking across your tiles.

Questions
Roof Cleaning in Didcot: your questions
Does a newer roof need cleaning?
Sometimes, yes. Even a fairly recent concrete roof can carry moss along its lower courses and lichen on its profiles, particularly where it is shaded. A light film may only need a gentle clean, while heavier growth needs hand removal first.
Do homes in Ladygrove and Great Western Park need a special method?
No. The development matters less than the covering itself. Newer homes often have concrete tiles, but we still assess each roof individually, because shade, orientation and condition vary from house to house.
Can you remove very heavy moss?
Yes, in most cases. Thick growth is lifted by hand from access equipment before any water reaches the roof, which keeps the cleaning stage gentle. We confirm at the site visit that the tiles are sound enough for the work.
Will cleaning repair cracked or slipped tiles?
No. Cleaning may make existing defects easier to see, but repairs are a separate job for a roofer. We report anything obvious that we notice so you can arrange the right work.
How long does Chiltern EverGuard™ last?
Typically 12 to 24 months. The exact period depends on shade, nearby trees, exposure and the roof itself. We email you as the protection period nears its end and offer a free assessment to see whether retreatment is needed.
Can my roof be cleaned in cold weather?
Yes, the moss removal can go ahead through the year. The treatment needs settled, frost-free conditions, so in a cold snap we remove the moss first and return to apply it when the weather allows.
Do you inspect the roof before quoting?
Yes. Every quotation follows a free site visit where we assess the roof from the ground and, where appropriate, by drone. We share what we see and explain our recommendation before you decide.
