Roof Moss Removal in Southall
Moss Removal for Southall’s Interwar Roofs
Southall’s interwar semis and terraces mostly have hipped roofs covered in clay or concrete tiles. The concrete interlocking tiles fitted to many of them have a textured surface that holds moisture, and on north-facing hips and rear slopes moss settles into the grooves where each tile interlocks with the next. Ashlar Roofing carries out roof moss removal across UB1 and UB2 in the London Borough of Ealing.
When moss fills the interlocks, it stops them doing their job. Water that should run down the channel between tiles is held back or diverted, and in heavy rain it can be pushed sideways under the tile beside it. Clearing the interlocks restores the drainage the tile was designed for.
Hips and ridges bedded in mortar also gather moss along their edges, and the mortar can be loosened when roots work into cracks. We clear these carefully and point out any loose ridge or hip tiles.

Southall
Dormers, Extensions and the Grand Union Canal Side of UB2
Many Southall houses have rear dormers and hip-to-gable loft conversions, which add flat roofs and new tile junctions. Moss collects on dormer roofs, especially in corners and at the drip edge, and in the junctions where new tiles meet old. We clean these as part of the main roof.
Rear extensions are common too, and water from the main roof often runs onto them. Moss washed off the main roof can settle on the extension below, so we check and clear that roof as well.
Streets close to the Grand Union Canal and the open land around it can stay damper than others, and roofs there may need cleaning more often.
Many UB1 and UB2 roofs have satellite dishes, aerial brackets and solar panels fixed to the slopes, and moss gathers in the sheltered pockets around them. We clean carefully around these fixings without disturbing them, and if a bracket has loosened the tiles beneath it, we point it out so it can be dealt with before it lets water in.


What's included
What a Roof Moss Removal Visit Covers
The main parts of the job, each listed in your quote.
- Moss lifted off by hand with scrapers and brushes, working down the slope so tiles are not forced up.
- No pressure washing, which can strip tile surfaces and drive water under the laps.
- A biocide treatment over the cleaned roof to kill remaining spores and slow regrowth.
- Valleys, hips and ridges cleared, as moss gathers where water runs slowest.
- Gutters, outlets and downpipes cleared of the moss washed into them.
- Photos of any slipped, cracked or loose tiles found while we are on the roof.

Pricing
What Roof Moss Removal Costs in Southall
In Southall, the price of a roof clean depends on:
- The area and pitch of the roof
- How thick the moss is and how long it has been growing
- Access, including whether a tower or scaffold is needed
- The covering, as fragile clay, slate and older concrete tiles need more care
- How much gutter and downpipe clearance follows the clean
