A well-maintained roof should last at least 25 years, depending on the materials used. However, the growth of lichen and moss can reduce this lifespan if left untreated.
These organisms thrive in damp, shaded areas, which means roofs are often a prime spot for them to settle. Over time, their presence can cause significant damage, leading to costly repairs or even the need for a full roof replacement.
At Swansea Clean & Seal, we specialise in cleaning and maintaining roofs to prevent such problems. In this blog post, we’ll explain why lichen and moss grow on your roof, the risks they pose, and how professional cleaning can help protect your home. Let’s get started with these roof cleaning tips.
What Are Lichen and Moss?
Lichen and moss are two different types of organisms that commonly grow on roofs, especially in areas with damp and shaded conditions.
Lichen is a unique organism made up of both algae and fungus. It forms a symbiotic relationship, where the algae provide food through photosynthesis, and the fungus offers protection and structure. Lichen often appears as crusty or scaly patches in various shades of grey, green, or white.
Moss, on the other hand, is a simple green plant that thrives in moist environments. Unlike lichen, moss doesn’t have roots but uses tiny filaments to anchor itself to surfaces like roof tiles or shingles. It often grows in thick, green clumps and can hold moisture against the roof.
Both lichen and moss flourish in areas that don’t get much sunlight, making your roof an ideal place for growth, especially if it is shaded by trees or other structures.
Why Are They Growing on My Roof?
Lichen and moss grow on roofs for several reasons, most of which relate to the environment around your home. One of the main causes is moisture. Roofs that are frequently exposed to rain or damp conditions, especially in areas with limited sunlight, provide an ideal breeding ground.
If your roof has shaded areas due to nearby trees or other structures, it is more likely to retain moisture, creating the perfect environment for moss and lichen to grow.
Organic debris, such as fallen leaves, can also contribute to the growth of these organisms. When debris collects on the roof, it holds moisture against the surface, allowing moss and lichen to thrive.
Additionally, certain roofing materials, like clay tiles or asphalt shingles, are more porous, making them more susceptible to moss and lichen growth. The mild and wet climate in South Wales also accelerates the process, making regular roof maintenance essential in the region.
Is Moss and Lichen Harmful to My Roof?
In a word: yes. Both moss and lichen can be harmful to your roof if left unchecked. Moss retains moisture, and when it grows in thick clumps, it can lead to water being trapped against your roof’s surface.
This moisture can seep into tiles or shingles, causing them to weaken over time. Eventually, the trapped water can lead to rot, leaks, or even structural damage, which can be costly to repair.
Lichen, while not as thick as moss, can also cause damage. Its fungal components can slowly break down roofing materials, leading to the degradation of tiles or shingles.
Over time, lichen can also make the surface rough, allowing more debris and moisture to accumulate, further encouraging moss growth. Not only can moss and lichen impact the lifespan of your roof, but they also diminish its appearance, making your property look older and neglected. Early removal is key to preventing long-term damage.
DIY vs Professional Cleaning
While some homeowners may consider cleaning moss and lichen themselves, DIY methods are often ineffective and can be risky. Using a standard pressure washer, for example, can damage roof tiles or shingles, especially if too much force is applied.
High-pressure water can loosen tiles or even crack them, leading to more issues down the line. Additionally, climbing onto a roof without the right safety equipment or experience can result in accidents.
Professional roof cleaning offers a much safer and more thorough solution. At Swansea Clean & Seal, we have the expertise and equipment to safely remove moss and lichen without causing damage to your roof. We use commercial-grade cleaning solutions that are tough on moss and lichen but gentle on your roof’s materials.
Additionally, our biodegradable cleaning products ensure that your plants, pets, and the environment remain safe. Professional cleaning also provides longer-lasting results, preventing future growth.
