Quick answer
Moss is a soft green plant that holds water, while lichen forms crusty patches that bond more tightly to tiles. Both benefit from professional assessment because removal methods differ slightly.
What you need to know
Moss is usually thicker and holds more moisture against the roof surface.
Lichen can etch into older tiles over many years and may need gentler treatment.
We identify what is present during quoting so the correct cleaning approach is planned.
How David White can help
We assess each property individually before recommending work. For what is the difference between moss and lichen, 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.
