A roof covered in moss, algae and lichen doesn't just affect the appearance of your property – it can also contribute to blocked gutters, trapped moisture and unnecessary wear over time. At Costello & Son Cleaning Services, we provide professional roof cleaning and roof moss removal throughout Bury and Greater Manchester using a specialist cleaning method designed to safely restore your roof while protecting its long-term condition.
Unlike many roof cleaning companies, we never pressure wash roofs. High-pressure cleaning can damage roof tiles, remove protective surface coatings, loosen ridge pointing and force water beneath the roof covering. Instead, we use the latest Marshall Air System to carefully scrape away moss and organic growth before applying a professional-grade biocide treatment that continues working long after the visible moss has been removed. Every roof cleaning project also includes a full gutter clearance, leaving your entire roofline clean, clear and free-flowing.






Our specialist roof cleaning service has been developed to provide long-lasting results without exposing your roof to unnecessary pressure or damage. Every stage of the process is designed to safely remove moss, improve the appearance of your roof and help protect it against future organic growth.

Using the specialist Marshall Air System, we carefully scrape away moss, lichen and organic build-up from roof tiles without using pressure washing. This controlled method removes heavy moss safely while helping to protect the roof structure and minimise the risk of damage.
Once the roof has been cleared, we apply a professional biocide treatment to eliminate any remaining moss, algae and lichen spores. This helps prevent rapid regrowth while gradually restoring the roof's natural appearance and keeping it cleaner for longer.
Every roof cleaning project includes a complete gutter clearance as standard. All moss and debris removed from the roof is cleared from gutters and downpipes, helping ensure rainwater flows away correctly and reducing the risk of future blockages.









Many roof cleaning companies still use pressure washing to remove moss quickly, but this approach can often create more problems than it solves. High-pressure water can force moisture beneath roof tiles, damage protective tile coatings, loosen ridge pointing and increase unnecessary wear on the roof. While the roof may initially appear clean, pressure washing alone does little to prevent moss from returning if the remaining spores are not properly treated.
Our roof cleaning method has been developed to avoid these risks completely. By manually removing moss using the Marshall Air System and following the process with a professional biocide treatment, we achieve a thorough, long-lasting clean without exposing your roof to unnecessary pressure. This safer, more controlled approach helps protect your roof while reducing future maintenance and keeping it looking its best for longer.
Roof cleaning requires specialist knowledge, the right equipment and a cleaning method that protects your property rather than simply improving its appearance. We invest in modern roof cleaning technology and proven treatment methods to deliver outstanding results with long-term protection.

Looking for more information about our roof steam cleaning services? Here are answers to some of the questions we are asked most often.
We never pressure wash roofs because high-pressure water can damage roof tiles, loosen ridge pointing, strip away protective coatings and force water beneath the roof covering. Our manual moss removal process using the Marshall Air System provides a much safer and more controlled alternative.
We carefully remove moss by hand using the specialist Marshall Air System before applying a professional biocide treatment. This removes heavy moss safely while helping prevent future regrowth.
Although visible moss can be removed manually, microscopic moss, algae and lichen spores often remain on the roof. Our professional biocide treatment kills these remaining spores, helping keep the roof cleaner for much longer and slowing future regrowth.
Yes. Every roof cleaning project includes a complete gutter clearance. All moss and debris removed during the cleaning process is cleared from the gutters and downpipes to ensure rainwater can flow away correctly.
No. Our roof cleaning method has been specifically developed to protect your roof. By avoiding pressure washing and using manual moss removal instead, we significantly reduce the risk of damage to roof tiles and the roof structure.
Every property is different, but the professional biocide treatment continues working after the roof has been cleaned, helping slow the return of moss, algae and lichen for significantly longer than cleaning alone.
Yes. We clean a wide range of residential roof types and assess every property before work begins to ensure the safest and most suitable cleaning method is used.
