How do you clean a roof?
When you notice that your roof is covered in moss you know it maybe time to clean it But How? Roofs are high up and awkward to work on. Especially if you don’t have a head for heights.
Prevention is always better than cure, however if your roof is now covered and your reading this article well then It to late to prevent the moss from coming in the first place.
Over time roofs can become infested with micro-organisms eating away at your roof. Many people ask
Where does roof moss come from?
Well over time the wind, rain and weather cycles blow nature onto our roofs. Microorganism colonise on the surface, when it rains the water feeds these growths much like when you water a plant it grows.
Without water or sunlight these grows would not grow. So you see just like plants or even weeds you can pull out the weed but it will always come back unless treated with a weed killer. Much like moss, Algae and lichen growing on your roof they need to be treated not just cleaned.
So how can I clean my own roof?
Many people believe pressure washing a roof is a good way to clean a roof. Well yes pressure washing roofs is a good way to make the roof look clean however before you take to the pressure washer you have a few things to think about beforehand.
- Broken tiles & water getting in
- Safe roof access

I have seen people DIY and pressure wash their roof with no safety what so ever walking around on a slippery wet surface over 2 stories high with a high powered power washer is an accident waiting to happen.. You need to clean your roof in the safest way. Is pressure washing really the answer? Well remember we earlier spoke about cleaning and treatment and the two different methods!.
Pressure washing a roof will only make the roof appear clean, it will not kill the root of the moss, pressure washing is not a treatment. In fact power washing helps the moss and algae recolonise Quicker as pressure washing uses mass amounts of water! Have you connected the dots yet?
Water feeds micro-organisms growing on your roof! Pressure washing just gives it a hair cut and tidy’s it up. But remember if you want to pressure wash your roof do so in a safe manner and watch out for broken tiles as pressure washer are renowned for causing damage to roof let alone the water ingress they can cause.. I would personally never pressure wash a roof. But hey its your roof its up to you how much time or money you want to invest un getting a clean roof. Remember pressure washing can cause lots of damage so think twice about pressure washing your roof.
