The cost of cleaning a roof in Cork depends on the size of the property, whether the roof is slate or tile, the amount of moss and organic growth present, access and the type of treatment required. A proper roof clean is also about more than improving appearance — the cleaning method needs to be appropriate for the roof covering and carried out without unnecessarily damaging tiles, slates or surrounding details.
How Much Does Roof Cleaning Cost in Cork?
Typical roof cleaning prices range from €400–€500 for a 2-bed terraced tiled roof and €500–€650 for a 3-bed semi-detached tiled roof, up to €650–€850 for a detached tiled property. Slate roof cleaning typically costs €450–€750. Published prices are plus VAT and exclude scaffolding.
These prices are intended as a guide. Roof size, condition, access, moss growth and any additional areas or extensions can affect the final quotation.

How Much Does It Cost to Clean a Tiled Roof?
For a typical tiled residential roof in Cork, the price generally increases with the size and complexity of the property.
A 2-bed terraced tiled roof typically costs €400–€500 to clean, while a 3-bed semi-detached property typically costs €500–€650. A bungalow typically ranges from €550–€750, with a larger detached tiled property generally costing €650–€850. Published prices are plus VAT and exclude scaffolding.
These prices include soft washing, removal of moss and algae and a full biocide treatment.
The property type is useful for giving homeowners a realistic guide, but it does not determine the price on its own. Two semi-detached houses can have very different roof areas, extensions, access conditions and levels of moss growth.
How Much Does It Cost to Clean a Slate Roof?
Our typical price for cleaning a slate roof is €450–€750. Published prices are plus VAT and exclude scaffolding.
Slate requires a careful approach. We use a gentle low-pressure cleaning method together with biocide treatment, helping clean the roof while protecting the slate surface.
This distinction matters because roofing materials should not simply be treated as interchangeable surfaces. A cleaning method appropriate for one roof covering may be unnecessarily aggressive for another.
What Is Included in a Roof Clean?
For our standard tiled-roof cleaning prices, the work includes a soft wash, moss and algae removal and full biocide treatment.
That distinction is important when comparing roof cleaning prices. A quotation for simply removing visible moss is not necessarily equivalent to one that includes cleaning and subsequent treatment.
A typical roof clean may include:
Assessment of the existing roof condition
Soft washing appropriate to the roof covering
Removal of visible moss and algae
Full biocide treatment
Care around roof edges and flashings
Consideration of extensions and additional roof areas
Identification of obvious damaged roofing materials
Advice on future roof maintenance where required
What Is Soft Washing a Roof?
Soft washing is a lower-pressure approach to roof cleaning than aggressive high-pressure washing. The aim is to remove unwanted organic growth while reducing unnecessary force against the roofing material.
This is particularly relevant on an older roof where tiles, mortar, flashings and other components may already have experienced years of exposure to Cork’s weather.
The correct cleaning method should always take account of what the roof is made from and its existing condition rather than treating every surface in exactly the same way.
Roof Moss Removal Cost in Cork
If a full roof wash is not required, we also offer moss removal and biocide treatment for €300–€450.
With this option, the existing moss is treated without washing the roof and a biocide treatment is applied to help prevent regrowth.
This can be suitable where the objective is to control moss and organic growth rather than carrying out a complete cosmetic clean.
Soft Wash & Treatment
Includes cleaning of the roof surface, moss and algae removal and a full biocide treatment. Pricing varies according to property and roof size.
From €400 for a typical 2-bed terrace
Moss Removal & Biocide
No roof washing is carried out. Existing moss is treated and biocide is applied to help control and prevent further growth.
Typical price: €300–€450
What Is a Roof Biocide Treatment?
A biocide treatment is used to target organic growth on the roof and help slow its return after treatment.
Moss, algae and similar growth do not appear overnight, and treatment is intended to deal with more than simply the immediately visible appearance of the roof.
We include full biocide treatment with our standard tiled-roof soft-washing service and also offer a separate moss and biocide treatment where washing is not required.
Why Does Moss Grow on Roofs in Cork?
Cork’s relatively mild and wet climate provides favourable conditions for moss, algae and other organic growth. Roof sections that receive less direct sunlight can remain damp for longer, making them particularly susceptible.
Nearby trees can also contribute shade and organic debris, while valleys, gutters and areas around roof features can retain moisture and material washed down from higher sections of the roof.
A small amount of surface growth is not automatically evidence of a roofing defect, but significant moss accumulation can hold moisture and obstruct the normal movement of rainwater and debris.
What Affects the Cost of Roof Cleaning?
The number of bedrooms or property type gives a useful starting point, but several practical factors determine the actual amount of work involved.
Roof Size
A larger roof naturally takes longer to clean and requires more treatment. Additional areas over a standard roof size are typically charged at €14–€18 per m².
Slate or Tile
The roof covering determines the appropriate cleaning method. Slate in particular requires a gentle low-pressure approach to protect its surface.
Moss & Algae Growth
A heavily affected roof can require more preparation and treatment than one with relatively light organic growth.
Roof Access
Property height, roof pitch, extensions and surrounding access all influence how safely and efficiently the roof can be worked on.
Extensions
Rear and side extensions can substantially increase the total roof area beyond what might normally be expected from the main property type.
Roof Condition
Damaged or deteriorated roofing may need attention before cleaning proceeds, particularly if tiles, slates or other components are already vulnerable.
How Much Does Extra Roof Area Cost to Clean?
For extensions or additional areas above a standard roof size, we typically charge €14–€18 per m². Published prices are plus VAT and exclude scaffolding.
This is particularly relevant for properties that have been extended. A house described as a three-bed semi, for example, may have substantially more roof area than a standard property if it includes a large rear or side extension.
The per-square-metre figure applies to the extra area rather than acting as a universal calculation for the entire roof.
How Often Should a Roof Be Cleaned?
There is no fixed cleaning interval that suits every Cork property. How quickly moss and algae return depends on factors such as shade, nearby vegetation, roof orientation, drainage and exposure.
A roof surrounded by mature trees or with shaded slopes may develop visible growth considerably faster than an open property receiving more sunlight.
Periodic inspection is therefore more useful than automatically cleaning a roof according to a rigid timetable.
Annual Roof Maintenance Cost in Cork
We offer an annual roof maintenance check for €280–€420.
This includes cleaning the gutters, inspecting roof tiles, flashings and eaves, and providing a full report.
Routine checks can be particularly useful for older properties or roofs that have previously required repairs because smaller defects can sometimes be identified before they develop into more disruptive problems.
How Much Does a Roof Inspection Cost?
A standalone roof inspection and report typically costs €220–€320. Published prices are plus VAT and exclude scaffolding.
The service includes a full condition check, photographs and a written report.
This can be useful where you have concerns about the condition of a roof but do not yet know whether cleaning, maintenance or repair work is required.
Does Cleaning Your Roof Improve Its Appearance?
Yes. Removing accumulated moss, algae and surface growth can make a substantial visual difference, particularly on roofs that have not been cleaned for many years.
However, appearance should not come at the expense of the roofing material itself. The objective is to clean the roof using a method appropriate to its construction rather than trying to make an older roof look artificially new through excessive pressure.
Is Roof Cleaning Worth It?
Roof cleaning can be worthwhile where moss and organic growth have become significant or where improving the appearance of the property is important.
It also provides an opportunity for the roof surface to be viewed more clearly. However, cleaning should not be presented as a substitute for necessary repairs. If tiles, slates, flashings or other parts of the roof are defective, those issues need to be dealt with appropriately.
For that reason, the best approach depends on the condition of the individual roof rather than assuming every property simply needs cleaning.
