A roof will develop moss from time to time and a small amount will be unlikely to cause an issue. However if it starts to build up then it can cause a number of issues that need tackling. For instance, due to the sponge like nature, moss can absorb water and hold on to it, which means the roof will always be damp. This means there is a higher chance of it seeping through the chimney, tiles, rotting the timber underneath. This can cause structural hazards and expensive repair work. Even if you have a pitched roof, the water will not drain away if excessive moss is in the way. It can also fall off the roof into gutters and pipes (either by itself, or birds can drop it) which can obstruct the system. If the roofline isn’t cleared, then it will be another pricey replacement.
