Roof cleaning is one of the most in demand services offered by Softwashing UK. Mosses, algae, lichens, and other atmospheric growths can cause structural damage to a roof, whether or not the greenish hues are seen by some as ‘quaint’. A common bacteria, gloecapsa magma, also causes unsightly black staining on a roof. Once a roof becomes covered with moss it is well into its projected life cycle, at which point maintenance and cleaning becomes more vital than ever. The old fashioned solution is to resort to high pressure cleaning to blast moss from the roof surface. However, high pressure cleaning of aging roofs is an aggressive solution which can cause substantial damage, so it is not recommended by roofing material manufacturers or roofers associations.
Softwashing is a gentle solution to roof cleaning and restoration. We use a pH neutral blend designed to treat the specific roof infection and kill gloecapsa magma, and unlike high pressure blasting, our products do not damage the roof materials. We filter and cleanse the roof using our softwashing low pressure tank system, and use light brushing to ensure maximum sanitisation. Softwashing uses the power of chemistry to eliminate the infectant at both surface and root. The products activate in minutes and then last for months.
Our process gets fast results that continue over time:

Softwashing Uk treats every job as its own individual project, as such, the most suitable method will be proposed in our quotation. Over the many years we have been restoring render, we have found that the cleaning of it falls in to five categories:
This service is used when the render has not been cleaned for many years and the render is heavily stained with black mould, blackspot and lichens, as per the sliding photograph.
This method requires every square inch of the render to be low-pressure washed, or steam cleaned and treated with stain remover, multiple times to achieve the desired finish.
This service is our render restoration service above, followed by our biocide render
treatment service, below in point 5.
This service is for your day-to-day cleaning of render, that has average organic staining i.e. green, red and some black staining in areas. An example of this is showed in the
photographs.
This service is for your day-to-day cleaning of render which is followed by a biocide
treatment, to help keep the render cleaner for longer.
The application of a high quality HSE approved professional use only biocide. A biocide
treatment will help keep render looking clean, while reducing the need for more intensive
and expensive render restoration cleaning, at a later date.
Specialist biocide treatments for render are essential for maintaining the appearance and durability of render. Homeowners often underestimate the impact of weather on render. Over time, harsh conditions can lead to cracks, discolouration, and mould growth.
Applying anti-fungal solutions, prevents mould and algae growth. It’s crucial to address these problems early, as they can worsen over time.
Our professional-grade biocide acts fast against biological growth on all external hard surfaces, breaking the reproductive cycle of microbial surface contaminants.
Render is a popular exterior finish used on homes across the UK thanks to its smooth, attractive appearance and weather resistance. However, over time, render walls can become stained and discoloured by algae, moss, lichen, and general grime. That’s where Softwashing UK comes in.
We offer professional render cleaning using specialist soft washing technology — a safer, longer-lasting alternative to pressure washing.
Unlike high-pressure cleaning, which can cause cracks or damage to the render surface, our low-pressure soft wash system uses biodegradable cleaning solutions that penetrate deep into the render. This method safely kills algae, moss, and organic growth at the root without harming the render.
Our soft washing doesn’t just make your render look clean — it prevents the return of organic growth by eliminating spores and bacteria. This means your walls stay cleaner for longer, reducing the need for frequent treatments.
We don’t just clean — we treat. Our softwash solution includes a biocidal treatment that destroys moss, algae, and lichen at the source, ensuring your render remains clear and protected from recurring growth.
High-pressure washing can damage render by causing cracks or eroding the surface finish. Our soft wash method is gentle enough to protect all types of render finishes while being powerful enough to tackle years of staining and biological contamination.
When you choose Softwashing UK, you’re choosing fully trained, certified, and insured professionals. Our team is experienced in treating render walls with the correct softwashing techniques and is trained in safe chemical handling and property care.
Our cleaning solutions are pH neutral, fully biodegradable, and environmentally responsible. They’re completely safe for children, pets, and surrounding greenery when used correctly — a key priority on every project.
We pride ourselves on delivering reliable, professional service from start to finish. From your first enquiry to the final inspection, you’ll experience great communication, punctuality, and results that exceed expectations.
Cleaning your render not only enhances the look of your home but also protects the structure beneath. Our cleaning service helps preserve the surface by preventing the biological damage caused by mould and algae, extending the life of your exterior finish and boosting curb appeal.

Thank you very much!Posted on Paul WelshTrustindex verifies that the original source of the review is Google. We’ve used Softwashing a number of times over the past few years to clean the exterior of our house, gutters and patio. Every time it has been a fantastic service, always going above and beyond, whether it’s attacking a stubborn rust stain or taking time to explain the process. We have recommended them to friends and neighbours and using them every year is testament to how happy we are with the work they do. Thanks!Posted on Andrew CovellTrustindex verifies that the original source of the review is Google. The service was great, Gavin arrived on the dot of eight o’clock and he then talked me through the process before starting. He worked diligently using a range of different techniques to address the various issues. At the end the render looked like new! Would definitely recommend and will have them back again when it needs doing again!Posted on Peter GrantTrustindex verifies that the original source of the review is Google. As a director of and on behalf of Wardour Court Management Company and residents I wish to record our thanks to Gavin and his team. The property is a sensitive building constructed of Chilmark stone, it had not been cleaned for some time and was looking the worse for wear. They were all extremely efficient and professional as well as very pleasant and easy to talk to despite the difficulties they encountered, which included having to work 17 hours on one of the days. All the residents I have spoken to have expressed how pleased they are with the result, as are the directors of Wardour Court Management Co. We would happily use this company again and are equally happy to recommend them to others.Posted on Ann Grant JewelleryTrustindex verifies that the original source of the review is Google. Gavin and his team recently cleaned the Chilmark stone courtyard mews where I live. The stone was in dire need of cleaning and proved to be a very difficult job including one 17 hour day. Despite the difficulties he and his team remained pleasant, friendly and very professional leaving us with what I can only describe as a transformation ... our ugly duckling has become a swan. I can't thank them enough for their dedication and would happily recommend him and his company.Posted on City Stays sw LtdTrustindex verifies that the original source of the review is Google. One of our properties, which is a rental, was a complete eye sore on the exterior surfaces, which needed rectifying before it was able to go back on the rental market. After ringing around different companies, Softwashing UK stood out and understood our requirements. Softwashing UK Soft wash cleaned 15 years' worth of bad organic staining from our K-Rend render, brickwork, and all rain water goods to the property. We honestly could not believe the results that were achieved. The render now looks like the day we had it rendered. On the day of the work ne carried out, the guys turned up on time and carried out the job respectfully and professionally. It's great to see good tradesmen still exist. We highly recommend the soft wash service they offer, and we will be sure to recommend Softwashing UK our friends and family's.Posted on James CTrustindex verifies that the original source of the review is Google.
