Quick answer
Yes, where appropriate, we can apply a biocide treatment after cleaning. This helps slow down organic regrowth and keeps the roof looking cleaner for longer. We will advise whether treatment is suitable for your roof.
What you need to know
Biocide treatment targets remaining spores and slows moss, algae and lichen from returning quickly.
It is applied after debris is removed so the product reaches the tile surface effectively.
Some very porous or fragile roofs may need cleaning only; we will tell you if treatment is not recommended.
How David White can help
We assess each property individually before recommending work. For do you apply a treatment after roof cleaning, that means checking access, roof or gutter condition, and any risks to neighbouring properties.
You can send your postcode and photos for a remote quote in many cases. If the job needs a closer look, we will say so upfront rather than guessing on site.
What to expect on the day
Our team works safely from ladders, towers or MEWPs depending on the building. We protect gardens, paths and driveways where moss or debris may fall, and we clear up when the job is done.
We will confirm timing, access and parking before we arrive so the visit runs smoothly for you and your neighbours.
