Step 1 ### Tile assessment We identify tile type, age and condition to decide whether pressure washing is safe. 2. Step 2 ### Test patch A small inconspicuous patch is cleaned and inspected before the full job proceeds. 3. Step 3 ### Controlled wash Pressure is dialled to the minimum that removes growth without disturbing the tile surface. 4. Step 4 ### Biocide finish A post-clean biocide is always applied to slow regrowth. ## Frequently asked questions Does pressure washing damage roof tiles? It can. On concrete and clay tiles older than 15 years, high pressure removes the protective surface coating and accelerates moss regrowth. We assess every roof individually. When is pressure washing the right choice? Modern flat roofs, garage roofs, render and patios benefit from controlled pressure cleaning. Pitched tile roofs almost never do. ### Related services [Roof Cleaning Cobham](/roof-cleaning-cobham)[Roof Moss Removal Cobham](/roof-moss-removal-cobham)[Soft Wash Roof Cleaning Cobham](/soft-wash-roof-cleaning-cobham)[Gutter Cleaning Cobham](/gutter-cleaning-cobham)[Roof Algae Removal Cobham](/roof-algae-removal-cobham)[Roof Cleaning Cost Cobham](/roof-cleaning-cost-cobham) ### Areas we cover [Cobham](/areas/cobham)[Esher](/areas/esher)[Weybridge](/areas/weybridge)[Oxshott](/areas/oxshott)[Leatherhead](/areas/leatherhead)[Surbiton](/areas/surbiton)[Kingston upon Thames](/areas/kingston-upon-thames)[Epsom](/areas/epsom)[Guildford](/areas/guildford)[Walton-on-Thames](/areas/walton-on-thames) ### Free quote within 24 hours No phone tag — we'll email a fixed-price quote.
