Many homeowners don’t notice the green patches growing on their roof. But this seemingly harmless roof moss could be silently damaging your roof tiles and putting your home at serious risk.
Why does moss grow on roofs?
Moss and algae thrive in damp, shady conditions. In the wet climate of London and surrounding areas, roof moss is extremely common. It loves north-facing roof slopes and areas shaded by trees. Unlike most plants, moss doesn’t have roots but tiny structures that help it cling to surfaces.
Moss can grow quickly once spores settle on your roof. The right conditions – moisture, shade, and a bit of organic matter – allow moss to spread rapidly across your roof tiles.
The dangers of roof moss
That innocent-looking green carpet on your roof can cause serious damage to your roof over time:
Moisture damage to roof tiles
Roof moss acts like a sponge. It soaks up rainwater and holds it against your roof tiles for long periods. This constant dampness is terrible for most roofing materials.
For tiles common in London homes, this moisture becomes especially dangerous during winter. Water trapped by moss freezes, expands, and can crack tiles. The persistent moisture accelerates weathering, making tiles more vulnerable to damage.
Physical damage from moss growth
As moss grows and spreads, it doesn’t just sit on your roof – it pushes into gaps and can lift tiles out of position. This creates entry points for water, which can damage timbers, ceilings, and insulation, leading to costly internal repairs.
Blocked gutters and drainage problems
During heavy rain, chunks of moss wash down into gutters, causing blockages. Water then overflows, potentially damaging walls, foundations, and fascia boards. A simple gutter blockage from moss can trigger expensive problems throughout your home.
Professional roof cleaning – the safest solution
When you spot moss on your roof, it’s time for professional help. Our roof cleaning service in London uses soft wash roof cleaning techniques that remove moss without damaging your roof.
The roof moss removal process should include:
- Inspection for damaged tiles
- Gentle cleaning to remove moss and algae
- Preventative treatments to discourage regrowth
- Gutter clearing to ensure proper drainage
Many homeowners attempt DIY moss removal using pressure washing, but this often causes more harm than good. Professional roof cleaning services from BaMaPa Cleaning use gentle but effective techniques that protect your roof’s structure.
