Professional Roof Cleaning & Steam Moss Removal in London

Your roof is one of the most important parts of your property, protecting your home from the elements year-round. However, constant exposure to rain, wind, moisture, and pollution can lead to the build-up of moss, algae, lichen, and other organic growth that can damage the appearance and condition of your roof over time.


At All Stone Cleaning, we provide professional roof cleaning services throughout London and the surrounding areas, helping homeowners restore and protect their roofs using safe, effective cleaning methods. Moss and algae can trap moisture against roof tiles, increasing the risk of tile deterioration, blocked gutters, and costly repairs if left untreated.


We specialise in professional steam roof cleaning, a low-pressure cleaning method that safely removes moss, algae, lichen, dirt, and biological growth without the risks associated with aggressive pressure washing. Our steam cleaning process delivers exceptional results while preserving the integrity of your roof tiles.


Our roof cleaning service includes:

• Manual moss removal where required
• Low-pressure steam roof cleaning
• Moss, algae and lichen removal
• Professional biocide treatment to inhibit regrowth
• Gutter clearing and debris removal
• Full roof inspection during the cleaning process


Steam cleaning is widely regarded as one of the safest and most effective methods of roof cleaning. The high-temperature steam eliminates spores at their source, restores the appearance of your roof, and helps keep it cleaner for longer.


Whether you have a tiled roof, slate roof, concrete roof tiles, or a commercial roofing system, our experienced team has the knowledge and equipment to deliver outstanding results.


If you're looking for reliable roof cleaning in London, roof moss removal near you, or professional steam roof cleaning services, All Stone Cleaning provides fully insured, affordable, and long-lasting solutions across Greater London and the surrounding areas.
