Roof Cleaning
Safely remove moss, algae, lichen, and black streaks from your roof with our professional soft wash cleaning service across Lancashire, Greater Manchester, and Merseyside.
Protect Your Roof, Protect Your Home
Moss, algae, and lichen on your roof are more than just an eyesore — left untreated, they can cause serious damage. Moss retains moisture against the surface, accelerating the deterioration of tiles and leading to costly repairs. Our professional roof cleaning service removes organic growth safely and effectively, extending the life of your roof and restoring your home's kerb appeal.
We use a low-pressure soft wash system rather than high-pressure blasting, which protects your tiles from damage while delivering a thorough, long-lasting clean. All treatments include a biocide application to kill growth at the root and inhibit regrowth for years to come. We cover all roof types across Lancashire, Greater Manchester, and Merseyside.
What We Treat
Types of Roof Cleaning
Moss Removal
Moss is the most common roof problem in the UK — and one of the most damaging. It holds moisture against the tile surface, causing freeze-thaw damage in winter and accelerating tile degradation over time. We manually remove heavy moss growth before applying a biocide treatment and soft washing the entire roof surface, leaving it clean and protected.
Algae & Black Streak Removal
Black streaks on roof tiles are caused by a form of algae called Gloeocapsa magma. While it doesn't damage tiles as aggressively as moss, it spreads quickly and significantly affects the appearance of your property. Our soft wash treatment kills the algae at the source and removes the staining, restoring the original colour of your tiles.
Lichen Treatment
Lichen is the most stubborn form of organic growth on roofs — it bonds directly to the tile surface and cannot be removed by pressure washing alone. We apply a specialist lichen treatment that breaks down the organism over time, followed by a soft wash to clear the surface. In severe cases, a follow-up treatment may be recommended for full removal.
Concrete Tile Roof Cleaning
Concrete tiles are porous and particularly susceptible to moss and algae growth. We use a controlled soft wash approach to clean the surface without dislodging or cracking tiles, followed by a biocide treatment to prevent rapid regrowth. We can also apply a tile sealant to reduce porosity and make future maintenance easier.
Clay & Slate Roof Cleaning
Clay and natural slate tiles require extra care — high-pressure washing can crack or dislodge them entirely. Our low-pressure soft wash system is perfectly suited to these delicate surfaces, delivering a thorough clean without any risk of tile damage. We treat the surface with a biocide to kill existing growth and protect against future contamination.
Roof Sealing & Protection
After cleaning, applying a roof sealant is the most effective way to protect your tiles long-term. The sealant penetrates the tile surface, reducing porosity and making it far harder for moss, algae, and lichen to take hold again. It also helps protect against frost damage and UV degradation, extending the lifespan of your roof significantly.
How We Work
Our Cleaning Process
Safe, thorough, and built to last
Roof Survey
We inspect the roof from ground level and up close to assess the surface type, extent of growth, and any areas requiring special attention.
Moss Removal
Heavy moss is manually scraped and removed before any washing begins, ensuring the biocide and soft wash can reach the tile surface directly.
Biocide Treatment
We apply a professional-grade biocide across the entire roof surface to kill moss, algae, and lichen at the root before washing.
Soft Wash Clean
Using low-pressure soft washing, we rinse the roof thoroughly — removing dead growth and staining without any risk of tile damage.
Optional Sealing
We can apply a protective roof sealant to reduce porosity, inhibit future growth, and extend the life of your tiles.
