Roof Moss Removal › Maesteg › Guide
The quickest way to remove moss is rarely the kindest to the roof. Many tiles in Maesteg are old and weathered, and the roofs are often steep and awkward to reach. Our method is slower and more careful, and it is built around protecting the tile surface and the laps.
Why we avoid jet washing
High-pressure washing is the method most often blamed for tile damage. The jet drives water up under the laps, into the roof space, and it strips the granules and glaze from concrete tiles and can crack slate. The roof looks clean for a week, then ages faster than it should. We do not recommend it. Tiles that have already weathered, as many on older Maesteg terraces have, suffer most.
Hand clearing and brushing
We lift moss away by hand and brush the tiles, working down the slope with the lie of the tile so we are not pushing growth up under the edges. It takes longer than blasting, but the surface of the tile is left intact. On the steeper terrace roofs of Maesteg and Caerau we set up access carefully first, and we keep the debris contained so it does not end up in neighbours' yards.
Gutters, valleys and the roof edge
Moss does not stay on the tiles. It washes down into valleys, gutters and hoppers, where it blocks the flow. We clear these as part of the job, then check that water now runs away freely, since a blocked valley can send rain over the side and into the wall below.
- Valleys cleared to a clean channel
- Gutters and downpipes emptied and flushed
- Ridge and verge edges looked at
- Debris taken away, not left in the garden
What we look for once it is clear
A mossy roof can hide a lot. With the growth off we can see slipped, cracked or frost-damaged tiles, failing ridge mortar and worn flashings. We tell you what we find and what each repair involves, rather than patching things quietly or leaving problems to turn into leaks. Those repairs are quoted separately so you can decide what to do and when.
The treatment afterwards
Once the roof is clear and dry enough, we apply a treatment to slow regrowth. It is not a magic fix, and we do not say it will keep moss away for good, but it helps the roof stay cleaner for longer, particularly on shaded and north-facing slopes. Applying it to a clean roof matters, as a treatment sitting on thick moss does little.

Common Questions
Can moss removal damage my tiles?
It can if the wrong method is used. Pressure washing and scraping strip the surface and force water under the laps. Hand clearing and brushing are far gentler, and we check the tiles for existing damage before and after we clear them.
How long does moss removal take on a terrace?
It depends on the length of the roof, the thickness of the moss and the access. A typical house takes a day or less, but a long run across several tiles or heavy growth takes longer. We give you a sense of timing once we have seen the roof.
Do you clear the gutters at the same time?
Yes. Moss and its debris wash down into the gutters and valleys, so we clear them as part of the work and check that the water runs away. A blocked gutter would undo much of the benefit.
