Moss might look harmless — even charming on an old cottage — but on a roof it’s working against you. Understanding how it damages tiles explains why professional moss removal and treatment are worth every penny.
How moss damages a roof
Moss traps moisture against the tile surface and pushes rainfall between the joints. In as little as one season it can spread across gaps and lift tiles at the edges, leading to loose or cracked areas and the risk of leaks. In winter, the trapped water freezes and expands — opening those gaps even further.
Removal without damage
We remove roof moss by hand and with soft-treatment techniques, always ensuring the tile surface remains undamaged. The debris is cleared from the roof and the gutters, so nothing washes into your drainage system afterwards.
The treatment that stops it coming back
After cleaning, a specialist anti-fungal treatment is applied across the entire roof to kill the micro roots left behind. This is the step most DIY attempts skip — and it’s why the moss returns within months. For properties with dense tree cover or persistent moisture, this preventative step makes a major difference.
If the moss keeps coming back
If you’ve noticed moss returning more often, or areas of the roof that never fully dry after rainfall, it’s time to have them checked.
