Professional pressure washing for robust roof types. Controlled techniques for effective moss removal across Yorkshire.
Roof pressure washing is a highly effective method for removing moss, algae, and organic growth from robust roof types. Unlike standard pressure washing, roof cleaning requires specialist knowledge, controlled pressure levels, and proper safety measures.
Our IPAF and PAL certified technicians are trained in safe roof pressure washing techniques. We use appropriate pressure levels for your specific roof type - enough to effectively remove moss and growth, but controlled to prevent tile damage.
This method is particularly suitable for concrete tiles and robust clay tiles in good condition. For older or more delicate roofs, we recommend our soft scraping method as the safer alternative.

Common questions about roof pressure washing
Pressure washing is suitable for robust roof types such as concrete tiles and certain clay tiles in good condition. However, it's not recommended for older, fragile, or slate roofs. We always assess your roof first and recommend the most appropriate cleaning method. For delicate roofs, our soft scraping method is the safer choice.
We use controlled, appropriate pressure levels based on your specific roof type and tile condition. Unlike general pressure washing, roof cleaning requires specialist knowledge and equipment. Our technicians are trained to use the correct pressure - enough to remove moss effectively but not so much that it damages tiles or dislodges them.
When performed correctly by trained professionals using appropriate pressure levels, pressure washing should not damage robust roof tiles. However, incorrect pressure or technique can cause damage, which is why we only use this method on suitable roof types and always conduct a thorough assessment first. For older or more delicate roofs, we recommend our soft scraping method instead.
Roof pressure washing requires significantly lower pressure, specialized techniques, and extensive safety measures. Working at height adds complexity, and roof tiles are more delicate than driveway surfaces. Our technicians are IPAF and PAL certified for working at height and trained specifically in roof cleaning techniques. It's a completely different skill set from ground-level pressure washing.
Yes, all our roof cleaning services include professional biocide treatment as standard, regardless of the cleaning method used. After pressure washing removes the moss and organic growth, we apply a specialist biocide solution that kills remaining spores and prevents regrowth, keeping your roof cleaner for longer.
