When it comes to maintaining your property, roof cleaning might not be the first thing on your mind, but it’s certainly one of the most crucial aspects of home care. Many homeowners tend to focus on more visible areas such as the garden, windows, or façade, but the roof plays an equally important role in the overall health of your home - if not more so!
A clean roof not only enhances the aesthetic appeal of your property, making it look well-kept and attractive, but it also significantly extends the lifespan of your roofing materials by preventing damage caused by moss, algae, and debris build-up. Over time, these elements can lead to costly repairs if left untreated.
If you’re considering getting your roof cleaned but aren’t sure about the costs involved, you’re not alone. Understanding the financial aspect of roof cleaning can be challenging, as prices can vary based on several factors.
This WM Wash guide aims to clarify the process, helping you to understand the factors that influence roof cleaning costs in the UK, and providing you with a clearer picture of what to expect when you invest in this essential service. Whether you’re looking to maintain your property’s appearance or protect your investment from future damage, roof cleaning is a vital step in ensuring the longevity and durability of your home.
Before exploring the costs, it's essential to understand why roof cleaning is not just an aesthetic choice but a necessary maintenance task for your home. Over time, roofs naturally accumulate dirt, moss, algae, lichen, and other types of debris, especially in regions with a damp climate. While this organic growth may seem harmless at first glance, it can lead to significant problems if left unchecked...
These organisms thrive in moist environments and can quickly spread across your roof. Moss, in particular, tends to absorb and retain moisture, which can seep into the underlying roofing materials. This retained moisture can lead to the weakening of shingles or tiles, making them more susceptible to cracking, lifting, or even breaking off during storms or high winds. Over time, this moisture retention can cause more severe water damage to the structure of your roof, potentially leading to leaks and expensive repairs.

Lichen is another frequent invader of roofs, especially in areas with little sunlight and consistent moisture. Unlike moss, which grows on the surface, lichen can penetrate the surface of your roofing materials, particularly on tiles and shingles, causing degradation. The acids produced by lichen can slowly eat away at the roofing material, reducing its effectiveness and lifespan. If left untreated, lichen can cause irreversible damage, requiring sections of the roof - or even the entire roof - to be replaced.
In addition to biological growths, your roof is also subject to the accumulation of debris such as leaves, twigs, and dirt. This debris can clog gutters and downpipes, leading to poor water drainage. When water can't properly drain away from your roof, it can back up under the shingles or tiles, causing leaks and water damage to your home's interior. Additionally, the weight of accumulated debris can cause stress on the roof structure, leading to sagging or even structural damage over time.
Beyond the functional aspects, the appearance of your roof is an important consideration. A roof covered in moss, algae, and debris can make your home look neglected, reducing its kerb appeal and potentially lowering its value. Regular cleaning keeps your roof looking fresh and well-maintained, which can be particularly important if you’re considering selling your property in the future.
Regular roof cleaning isn't just about addressing immediate concerns; it’s also a long-term investment in your property. By removing harmful growths and debris, you can prevent the need for costly repairs or even a full roof replacement down the line. In this way, regular cleaning can save you thousands of pounds over the lifespan of your roof, making it a cost-effective preventive measure.
In summary, regular roof cleaning is essential not just for maintaining the aesthetic appeal of your home, but also for preserving the integrity and longevity of your roofing materials. By addressing the build-up of moss, algae, lichen, and debris, you can prevent moisture retention, structural damage, and costly roof repairs, ensuring that your roof remains in excellent condition for years to come.

The cost of roof cleaning can vary widely depending on several key factors, each playing a significant role in determining the final price. Understanding these factors can help you better anticipate the cost and ensure you’re getting the best value for your money.
The size of your roof is one of the most significant factors influencing the price of cleaning. Larger roofs require more time, effort, and materials to clean, which will naturally increase the cost. Roofs are typically measured in square metres, and most companies will provide a quote based on this measurement.
Additionally, larger roofs may require more extensive safety measures or equipment, such as scaffolding or harnesses, further adding to the cost. A more expansive area also means a greater accumulation of moss, algae, and debris, which can extend the time needed to complete the job.
The type and material of your roof are also crucial factors in determining the cost of cleaning. Different roofing materials require different cleaning methods, which can impact the price. For instance, cleaning a slate roof might cost more than cleaning asphalt shingles because slate is more delicate and requires a gentler approach.
Using high-pressure cleaning on delicate materials like slate or clay tiles could cause damage, so more careful and time-consuming methods, such as soft washing, might be necessary. Similarly, roofs with steep pitches or complex designs present additional challenges.
Steep roofs are more hazardous to work on, requiring specialised safety equipment and possibly more labour, which can drive up the cost. Complex designs with multiple angles, valleys, and elevations may also require more detailed and time-consuming work, contributing to higher overall expenses.
The amount of dirt, moss, and algae on your roof tiles will significantly impact the cost of cleaning. A roof with a substantial build-up of moss or algae will require more time and effort to clean effectively, often necessitating more intensive treatments. For instance, in cases where moss has deeply embedded itself into the roof surface, a simple wash may not suffice.
Instead, a biocide application might be required to kill off the moss and prevent regrowth, followed by a thorough cleaning process to remove the dead material. This additional step prolongs the cleaning process, adding to the overall cost. In more severe cases, pressure washing might be necessary to dislodge stubborn dirt and algae, which, while effective, can be more expensive due to the labour and equipment involved.
Roofs that are difficult to access or require additional safety measures will invariably increase the overall cost. For instance, properties with high roofs, steep pitches, or unusual designs often require scaffolding, harnesses, or cherry pickers to ensure the safety of the workers. These safety precautions are essential but add to the overall costs.
Geographical location can affect the price of roof cleaning services. In some areas, particularly in larger cities or more affluent regions, the cost may be higher. For example, roof cleaning in London or the South East may be more expensive compared to rural areas due to higher operational costs.
Now we've covered all of these factors, let's dive into our roof cleaning cost guide!
Roof cleaning prices can vary depending on various factors, but here’s a general overview of what you might expect to pay for a roof cleaning project in the UK:
The roof cleaning methods you use will also impact the cost, and it's essential to choose the right one (don't worry, we'll recommend the most suitable method!).
Here's a selection of methods to consider...
High-pressure washing is a popular method, especially for more robust roof materials like concrete tiles. It effectively removes moss, dirt, and algae. However, pressure washers aren't suitable for all roofs, particularly older or more delicate ones, as they can cause damage if not done correctly. This method is usually more affordable but might require additional treatments to prevent moss regrowth.
Soft wash roof cleaning involves using low-pressure water combined with specialised cleaning solutions. This method is ideal for roofs that are more delicate, such as slate or clay tiles. Soft washing is generally more expensive due to the specialised products and techniques required but is a safer option for many types of roofing.

DOFF cleaning is a specialised cleaning method that uses high-temperature steam to clean various surfaces, including roofs. The DOFF system heats water to around 150°C and then applies it at low pressure, which effectively removes moss, algae, lichen, and other types of dirt without damaging the underlying roof material. This method is particularly beneficial for delicate roofing materials like slate, clay tiles, and heritage buildings where maintaining the integrity of the material is crucial.
TORC cleaning is another specialised method often used for roofs that have more stubborn stains, pollution deposits, or graffiti. The TORC system works by combining a fine, inert abrasive powder with water and low pressure to gently but effectively clean surfaces. It’s particularly useful for stone and masonry roofs, where traditional cleaning methods might be too abrasive. This method is excellent for removing carbon staining and heavy pollutants without causing damage to the roof.
Steam cleaning is a versatile and effective method for roof cleaning that involves the use of high-pressure steam to remove dirt, moss, algae, and other contaminants from the roof's surface. Unlike DOFF cleaning, which operates at lower pressure, steam cleaning uses a more forceful application of steam, making it suitable for more robust materials like concrete tiles or metal roofs.
The high temperature of the steam not only cleans but also helps to kill off spores and bacteria, preventing the regrowth of moss and algae.
For roofs with significant moss build-up, manual scraping is often used before applying a biocide treatment. This method is labour-intensive and can increase the cost, but it’s highly effective for removing thick moss layers.
When you hire a professional roof cleaning company like WM Wash, you’re not just paying for the cleaning itself but for a comprehensive service that includes:
Given the potential damage that moss, algae, and debris can cause, regular roof cleaning is a wise investment. While it might seem like a considerable expense upfront, it can save you thousands of pounds in the long run by extending the life of your roof and preventing costly repairs.
You might be tempted to indulge in DIY roof cleaning to save money, but cleaning your own roof is fraught with hazards! Also, a pressure washer isn't always the right tool, and most people don't know how to handle these tools safely or accurately.
Roof cleaning costs can vary based on a range of factors, including the size of your roof, its material, and the extent of moss or dirt build-up. On average, UK homeowners can expect to pay between £400 and £1,000 for professional roof cleaners. While this might seem like a significant outlay, the benefits of a clean, well-maintained roof far outweigh the costs.
