Unfortunately moss won’t die during the winter. During dry spells it goes dormant until conditions improve. This means if you have moss on your roof the best time to take care of it is now.
What happens if you leave moss on your roof?
All roofs are susceptible to moss growth, but moss is particularly common and damaging to tiled roofs. If left unchecked, it can lead to a number of serious long-term issues. Not only will moss make your roof look quite unsightly, it can also cause structural damage and block your home’s drainage system.
When should I put moss killer on my roof?
The best time to treat roof moss is when it’s actively growing. Moss grows very little in summer, but it kicks into high gear during fall rains, moderate winters and early spring months. Treating right before peak fall rains is perfect timing for roof moss treatments.

To avoid expensive repairs, moss should be removed from your roof tiles quickly if it is covering a significant area of your roof. Avoid pressure washing your roof to remove moss, as this could cause damage to the tiles and lead to the drenching of your roof interior.
Is it worth removing moss from roof?
Yes, you should! Even if moss doesn’t appear on some parts of a roof, it’s worth cleaning a roof properly to remove areas where moss has started to grow, but it isn’t yet visible. Moss retains water and if left on a roof for long periods, it can cause damage including cracks to tiles.
