Moss on rooftops might seem harmless, even charming in some cases, but it’s more than just a cosmetic issue. For homeowners across Leicester, moss buildup can silently cause serious structural damage, leading to costly repairs if left untreated. In this blog, we explore how moss affects your roof, why it matters, and how professional roof cleaning in Leicester can save you thousands in the long run.
How Moss Can Damage Your Roof
Moss doesn’t just sit on your tiles; it actively contributes to long-term wear and tear.
It Traps Moisture
Moss holds water like a sponge. When it accumulates on tiles, it prevents the roof from drying out properly. This leads to prolonged moisture exposure, which can cause tile degradation, promote rot in underlying structures, and encourage mould growth in your loft space.
It Lifts and Shifts Roof Tiles
As moss grows, it finds its way into the small gaps between roof tiles. When wet moss expands, it can lift tiles slightly, allowing water to seep underneath. This not only compromises waterproofing but can also dislodge tiles during high winds.
It Blocks Gutters and Downpipes
When moss dislodges and falls into gutters, it builds up quickly. Blocked guttering causes water overflow, which may damage fascias, soffits, and even the property’s foundations.
It Adds Unnecessary Weight
A heavy moss load can add significant weight to your roof, particularly when saturated with rainwater. This creates structural strain, especially on older properties.
Fact: According to Roofing Megastore, moss can reduce the lifespan of your roof tiles by as much as 10 years if left untreated.
How Moss Affects Your Home
The issues caused by moss are not just about the roof. Here’s how they affect your wider property:
- Increased maintenance costs from damaged tiles and water ingress
- Reduced kerb appeal, which can lower property value
- Higher risk of leaks, leading to mould, rot, and internal water damage
Professional Moss Removal vs DIY
While there are many “over-the-counter” moss removal treatments available, roof cleaning is not a job to take lightly. Here’s why calling a professional is the safest and most effective option.
Manual Moss Removal
Professionals use specialist scraping tools to remove thick moss layers without damaging tiles. This method is particularly effective on older roofs.
Biocide Treatment
After scraping, a biocide is applied to kill remaining spores and prevent regrowth. It ensures long-term cleanliness and protects against rapid re-infestation.
Safe, Low-Pressure Washing
Unlike DIY jet washing, which can strip tile surfaces and force water under the roof, professional cleaners use low-pressure systems designed specifically for delicate surfaces.
Expert Tip: Never use high-pressure washers on your roof. It may seem effective, but it often leads to more harm than good.
Signs Your Roof Needs Cleaning
Leicester homeowners should look out for these early warning signs:
- Green or dark patches on roof tiles
- Moss in gutters or on the ground after rainfall
- Visible lifting or uneven tiles
- Internal damp spots or mould in upper rooms
If you notice any of the above, it may be time to call in a roof cleaning specialist.
Booking your clean early in the season ensures availability. Our pressure washing slots often fill quickly during peak months.
Why Leicester Homes Are Particularly At Risk
Our local climate, with consistent rainfall and cool conditions, creates a breeding ground for moss. Homes surrounded by trees or with older tile types are especially vulnerable. With many Leicester properties featuring pitched, porous-tile roofs, staying on top of roof maintenance is essential.
