Local roofs
Sherborne is known for its honey-coloured stone houses, many with older clay tiles or natural slate that are brittle after decades of weather. Sheltered lanes and mature trees around the abbey and the older streets keep roofs damp, so moss and lichen build up quickly, while the newer estates on the edge of town have concrete tiles that stain with algae.
Sherborne is full of honey-coloured stone properties with older clay tiles and natural slate, and those roofs need a careful hand rather than a hard scrape. We choose the gentlest method that will actually shift the growth, clear the moss from the roof, gutters and ground, and finish with an HSE-approved biocide so it stays clear.
We also clean roofs in the villages around Sherborne, including Yetminster, Milborne Port, Bradford Abbas, Longburton.
Our methods
No single method suits every Sherborne roof. We look at the tile type, age and level of growth, then explain whether a low-pressure clean, softwash or biocide treatment is best.
Our preferred method when suitable
When your tiles are suitable we use a flat surface cleaner rather than a lance, so the water pressure is spread evenly and gently. The only thing that touches your tiles is water, and the improvement is instant.
Best for light algae and staining
A low-pressure chemical treatment that kills organic growth and lightens staining. Ideal for lightly soiled or more delicate roofs, or as follow-up maintenance after a full clean.
Available on request
Moss is physically scraped off by hand and a biocide is then applied to kill the remaining spores. It is often seen as the safest option, but in our experience metal tools can crack or dislodge brittle and weathered tiles.
What's included
What we remove
Moss
The most common problem on UK tiled roofs. It thrives on damp, shaded, north-facing slopes, holds water like a sponge, causes frost damage, loosens tiles and blocks gutters as it falls.
Algae
Dark green or black streaks and stains, most often on concrete tiles and slate. It rarely damages tiles directly but ruins the look of a home and usually leads to moss if it is left.
Lichen
Hard crusty white, grey or orange patches. More stubborn than moss or algae, it grows slowly on older roofs and can etch into the tile surface if left untreated.
Grime & pollution
Dust, soot, bird droppings and traffic pollution build up on roadside and town properties, dulling the colour of the roof and speeding up staining.

It depends on the size and pitch of the roof and how much moss there is. Our minimum charge is £600. Trace your roof on our satellite map to see a rough estimate in about 60 seconds, then we confirm a fixed price before booking.
Yes — as well as Sherborne itself we regularly clean roofs in Yetminster, Milborne Port, Bradford Abbas, Longburton and the surrounding area.
A Sherborne roof usually stays clear for 3 to 5 years after cleaning and biocide, though roofs shaded by trees may need treating again sooner.
