Home›Roof Cleaning & Moss Removal›Windsor
Moss, lichen and algae removed from Windsor roofs with a method chosen for your tiles – hand scraping, low-pressure washing or steam – plus an optional biocide and a full gutter clear once the roof is done.
Thick moss on a Windsor roof is about more than looks. The moss traps moisture against the tiles, which can encourage frost damage, and as it spreads it can lift tiles and work its way into the joints. Eventually clumps break free, landing on paths and blocking gutters. Our roof cleaning Windsor service tackles moss, lichen and algae carefully, with the cleaning method matched to the tiles on your roof.
Moss removal usually begins with hand scraping, using specialist made-to-measure scrapers that follow the shape of the tiles and lift moss from the laps and gaps without forcing anything. For algae, lichen and ingrained dirt, we can follow up with low-pressure washing or roof steam cleaning, both of which are far gentler than aggressive jet washing. Once clean, an optional biocide treatment can be applied to slow the return of growth. Finally, we clear the gutters and downpipes of all the debris the roof cleaning has released, so you are left with a clean roof and free-flowing drainage. Throughout, we work with the tiles rather than against them, which is the key to a result that looks good and lasts.
Windsor’s setting beside the Thames and alongside vast stretches of parkland makes it a natural home for roof moss. The river keeps humidity high, particularly in autumn and winter, and the trees of the Great Park, Home Park and the town’s many avenues provide shade that slows drying after rain. North-facing slopes and roofs overshadowed by mature trees can stay damp for long periods, ideal conditions for moss and algae to establish.
Roof types vary across the town. Period properties in the centre and in conservation streets near the castle often have clay tiles or natural slate, which need a delicate approach to avoid damage. Victorian terraces in Clewer usually have slate or clay roofs that have weathered over many decades, while the 1960s and 1970s homes in Dedworth often use concrete tiles with a textured surface that moss grips easily. Larger detached houses near St Leonard’s Hill and Old Windsor may have complex roofs with dormers, valleys and hips that trap debris and moisture, so moss often builds up there first and stays hidden from the ground until it starts shedding.
We carry out roof cleaning throughout SL4, including Eton across the bridge. If you are finding chunks of moss in the garden or your gutters keep filling even without trees nearby, it is a good sign the roof needs attention, and the sooner it is dealt with, the gentler the clean can be.
We start with your tiles and work out the gentlest method that will do the job properly.
We identify the tile or slate type, check its condition, look for any loose or damaged tiles, and assess the amount of moss, algae and lichen before recommending a method.
Thick moss is removed by hand using scrapers made to fit your roof’s profile, working carefully around each tile to avoid lifting or cracking them.
Remaining staining and algae are cleared with low-pressure washing or steam, depending on the tiles, followed by an optional biocide to slow fresh growth over the coming seasons.
We empty the gutters and downpipes of the moss and debris removed from the roof, then sweep up around the property so it is left clean.

A clay-tiled Victorian roof and a 1970s concrete-tiled one need very different handling. We choose from several techniques depending on what your roof is made of and what is growing on it:
We explain our recommendation, and why it suits your particular roof, before any work begins, so you know exactly what to expect.
Every roof is quoted individually, because size, pitch and tile type vary so much from one Windsor street to the next. The key factors are:

Yes, when done carefully. Many period homes in central Windsor and Clewer have clay tiles or slate that can be fragile. We use hand scraping and low-pressure or steam cleaning, avoiding high-pressure jetting that could damage the surface or force water under the tiles.
We can clean roofs on period and listed properties, as cleaning does not alter the building. We take extra care with traditional materials. If any repairs are needed, it is worth checking requirements with the Royal Borough of Windsor and Maidenhead before work is carried out.
It depends on shade, tree cover and moisture. Roofs near the river and parks in Windsor may see regrowth sooner than open, sunny ones elsewhere. Adding a biocide treatment after cleaning significantly slows the return of moss and algae, helping the roof stay clean for considerably longer.
No. We just need safe access around the outside and an outside power socket. We will keep you updated by message during the day, close the gates when we leave and send photos of the cleaned roof and cleared gutters so you can see the result.
Some moss will inevitably fall during the work, but we sweep up paths, patios and driveways and clear the gutters at the end. Delicate plants beneath the eaves can be covered if you let us know, and we aim to leave your property as tidy as when we arrived.
It can. Moss holds water against the tiles, which may lead to frost damage in winter, and it can lift tiles as it grows underneath. It also blocks gutters, causing overflow. Regular cleaning helps protect both the roof and the drainage.
