our roof cleaning process
Safe, thorough, and suitable for all roof types.At Adamson Exterior Cleaning, we use a low-impact, two-stage cleaning method that protects your roof while delivering lasting results.1. Manual Moss RemovalWe begin by carefully removing moss, lichen, and debris using specialist hand tools. This approach avoids the risk of damaging tiles or forcing water into the roof space — something that can happen with high-pressure washing, especially on older or more delicate roofs.
✅ Gentle on all tile types
✅ No high pressure
✅ Prevents tile dislodging or cracking.2. Professional Biocide TreatmentOnce the roof is clear, we apply a professional-grade biocide treatment. This safely kills any remaining spores and organic growth at the root level, helping prevent regrowth for 4 years or more.✅ Long-lasting clean without surface damage
✅ Continues working over time as rain activates the treatment
✅ Leaves tiles cleaner, healthier, and more resilient.Why This Method?While pressure washing can be effective in certain cases (on robust roof tiles and done with care), it isn’t always the safest or most appropriate option.Our method:Works on all roof types, including slate, clay, and older tilesReduces risk of water ingress and surface damageDelivers longer-term results thanks to the biocideIt’s the safe, proven choice for homeowners looking for both immediate improvement and long-term protection3.

❓ Frequently Asked QuestionsHow long will the results last?Once your roof has been treated, you can typically expect results to last around 4–5 years. The biocide continues working after application, helping to prevent moss and algae from returning by targeting spores and organic growth at the root.---Will roof cleaning damage my tiles?No — our method is designed to be gentle and safe for all roof types. We don’t use pressure washers, so there’s no risk of cracking tiles or forcing water underneath.
That said, if your roof has damaged tiles hidden beneath heavy moss, they may become visible once cleaned. We’ll always point these out, but they’re not caused by the cleaning process itself.---Why don’t you use pressure washing?While pressure washing might seem like a quick solution, it can cause serious damage to many roof types. Risks include:Broken tilesWater getting into your loft or under the tilesDislodging protective roof coatingsA lot of mess around your propertyOur method is cleaner, safer, and better suited to long-term roof health.---How much does it cost?Every property is different — the cost depends on the size of your roof, how much moss is present, what access is needed, and your tile type.
We always aim to be competitive and will give you a clear, no-obligation quote after assessing the job properly.---How long does the job take?Most roof cleaning jobs are completed in a day or two, depending on the size and amount of moss. We’ll always aim to work around your schedule and keep disruption to a minimum.
