Many homeowners think moss on the roof is simply a cosmetic issue—some even find it charming. But the truth is, moss can be surprisingly destructive and significantly shorten the lifespan of your roof. At Horncastle & Sons Roofing, we’ve seen firsthand how neglected moss can lead to costly structural issues, internal leaks, and even full roof replacements.
So why is moss such a problem, and what can you do about it?
The Hidden Dangers of Moss on Your Roof
Moss may seem harmless, but it behaves like a sponge, soaking up rainwater and moisture. When left unchecked, this moisture can travel beneath your roof coverings and into the timber structure underneath. Over time, this damp environment promotes wood rot, mould growth, and serious decay.
If the roof sheathing becomes saturated, your entire roofing system may lose structural integrity—posing a risk not just to your home, but also to your safety.
How Moss Affects Roof Drainage
One of the key benefits of a pitched roof is its ability to drain water effectively thanks to its slope. However, when moss takes hold, it can block the natural drainage channels between tiles. As the moss holds on to moisture, it stops water from running off efficiently, and this can cause pooling or backup.
Eventually, broken-off pieces of moss can clog gutters and downpipes, leading to even more serious issues like water ingress inside the property. At this point, you’re not just dealing with moss—you’re dealing with internal leaks and water damage.
The Right Way to Remove Moss
Moss removal needs to be carried out with care. A cleaning agent combined with a stiff brush is generally the safest way to remove moss without damaging your roof coverings. Although some contractors may suggest using a pressure washer, high-pressure water can actually cause more harm than good, especially if it forces water beneath the tiles or damages the surface.
Our team at Horncastle & Sons Roofing always uses the safest and most effective methods tailored to your roof’s materials and condition.
Prevention and Maintenance Tips
After moss has been removed, keeping your roof clean and clear is essential. Regular inspections can help identify any early signs of moss regrowth or drainage issues. Trimming nearby trees to reduce shade and debris can also minimise moss buildup over time.
