Although most mosses pose no danger to humans, moss growth can severely compromise your roof. Moss is incredibly effective at absorbing moisture, which means that any moisture trying to leave your roof will be captured.

Moss ​filling up the voids between roof tiles can lift the tiles and expose what lies underneath to the outdoor elements. This combination of excessive moisture and exposure to rainwater is what leads to serious structural damage such as rotting timber or damp insulation.

Moss spreads via releasing spores like many plants. Moss growth is far more likely on damp, cool surfaces that don’t receive much sunlight. This makes north-facing tiled roofs especially prone to moss and algae build-up, as they can quickly take root in the dark nooks and crannies between and under roof tiles, shingles or slates.

Moss can cause a lot of damage to your roof, but contaminants like fungi, green algae, mould, mildew or lichen on your roof surface are potential hazards to health, so it’s important to treat the roof with biocide solutions to ensure there is no chance they will grow back in the near future.
