County Meath has the kind of climate that moss loves. Wet winters, mild temperatures, shade from mature trees in rural townlands and suburban gardens — these are perfect conditions for moss, algae and lichen to colonise a roof. If your roof has green or black patches, discolouration, or visible moss growth along ridges and in valleys, it is not just a cosmetic problem and it will not resolve itself over time.
Mr Clean Roofing provides professional softwash roof cleaning across County Meath. Because we are roofers first and foremost, we approach roof cleaning differently from a general external cleaning company. We understand roof structures, we identify any tile damage or structural issues during the cleaning process, and we make sure the cleaning method used is appropriate for your specific roof type — whether that is natural slate, fibre cement, concrete tile or flat roofing.
Our softwash roof cleaning process removes all existing moss, algae, lichen and organic staining from your roof surface without the high pressure that damages tiles. A professional biocide treatment is then applied that kills any remaining spores and inhibits regrowth for an extended period — typically keeping your roof cleaner for significantly longer than a pressure wash alone.

No two roofs in Meath are the same — and no honest roofer will give you an accurate price without seeing your roof first. Here is exactly what determines the cost so you know what to expect before we arrive.
Size of Your Roof
The larger the roof area, the more time, labour and biocide treatment required. A standard three-bedroom semi-detached in Meath takes considerably less time than a large detached property or a sprawling bungalow. Roof area is the single biggest factor in the final price.
How Bad the Moss & Algae Growth Is
A roof with light algae staining takes far less work than one left for a decade with thick moss colonies along every ridge and valley. Heavy growth requires significant manual clearance before the softwash stage even begins — and that takes time. The longer moss is left, the more it costs to remove properly.
Pitch and Accessibility
A steeply pitched roof or a property where access is restricted adds time and complexity to the job. Single-storey properties and flat sections are more straightforward than tall, steeply pitched roofs on two-storey homes where additional access equipment is needed.
Whether Scaffolding Is Required
For most standard domestic properties across Meath we can work safely without erecting full scaffolding. Where a roof is particularly high or steeply pitched, scaffolding may be required — and where it is, we include this clearly in your written quote so you know the full cost upfront with no surprises.
The only accurate way to price your roof is to come and look at it — which we do for free, with no obligation and no hard sell. Patrick will inspect your roof, assess the extent of the growth, and give you a fixed written quote before any work starts. What you are quoted is what you pay.


In Meath's climate — wet winters, tree cover and typically moderate temperatures — most roofs benefit from professional cleaning every 3 to 5 years. Roofs with significant shade from overhanging trees, or north-facing roof slopes, may need attention more frequently as these conditions particularly favour moss growth.
Not with our method. Low-pressure softwashing does not damage tile surfaces, displace slates, or force water into the roof space. High-pressure jet washing can cause all of these problems — which is why we do not use it. We will always confirm the appropriate method for your specific roof type before starting.
A standard 3-bedroom semi-detached home typically takes 4 to 6 hours for the full process. Larger or more heavily moss-covered roofs may take a full day. We will give you a realistic timeframe when we survey.
Applied to a properly cleaned roof surface, a professional biocide treatment typically inhibits regrowth for 3 to 5 years in Irish conditions. Results vary depending on the amount of tree cover, the orientation of the roof and the exposure of the property.
We include a gutter clearance as part of every roof cleaning job — removing all debris that has come off the roof during the cleaning process and leaving the gutter system fully clear and flowing. There is no point in cleaning a roof and leaving blocked gutters beneath it.
We use professional-grade biocide treatments that are appropriate for use in proximity to gardens and planting. We protect surrounding areas during application and allow appropriate dwell time before any run-off occurs. We will discuss any specific concerns about sensitive planting near the house during the pre-job survey.

Whether your roof has a light covering of algae or years of heavy moss growth, we will come to you, assess the roof properly, and give you a fixed written quote at no charge. A clean roof lasts longer, looks better, and causes fewer problems — and with biocide treatment it stays that way.
