Roof Cleaning Questions Answered

Guidance on cleaning techniques and maintenance.

London's climate creates ideal conditions for biological growth: damp winters, shade from trees, and limited air circulation on north-facing slopes. Moss holds moisture against tiles, accelerating degradation and blocking gutters. Algae (the black streaking on mineral felt) thrives in similarly damp conditions. Properties near trees, water features, or with north-facing roof slopes are particularly susceptible.
When done correctly by professionals, pressure washing is safe for most roof tiles. We use low-pressure techniques (below 1500 PSI for clay and concrete tiles) and appropriate nozzles to avoid damaging surfaces. We assess your roof type before cleaning and adjust techniques accordingly. Tile cleaning is not suitable for brittle or already-damaged tiles — we identify these during survey.
Professional cleaning removes surface contamination without damaging tiles, coatings, or the underlying membrane. We avoid high-pressure that could dislodge tiles or force water beneath them. On flat roofs, we use gentler washing that protects the waterproofing layer. Our teams are trained to clean without causing damage.
We apply professional biocides — zinc or copper-based treatments that kill existing spores and prevent regrowth for 12-18 months. Application is even and thorough, reaching all roof surfaces. Annual or bi-annual maintenance visits include retreating to maintain protection. The biocide is diluted appropriately for the property and safe for surrounding planting.
Terraced house: 1 day. Semi-detached: 1-2 days. Detached: 2-3 days. Weather conditions affect timing — we avoid cleaning in rain, strong sun, or freezing temperatures. We always complete in a single visit where possible, leaving the property clean and tidy.
No — you do not need to be present during cleaning work. We work externally and do not need access to your property. If you are home, there will be some noise from pressure washing equipment. We always notify neighbours if our equipment will cause significant noise or disruption.
