Why clean a roof?
Moss, mould and lichen hold moisture against the roof and break down the surface. Left alone, they lead to early deterioration and costly repairs or a replacement. A clean now costs far less than fixing that later.
- Prevents early damage and deterioration
- Stops blockages that can force water back into the roof cavity and the house
- Extends the life of the roofing
- Keeps the muck out of your water tanks
- And it looks a lot better
How we do it
- CleanWe clean off the moss, mould and lichen, where there's safe access to the roof.
- ClearThe gutters are cleared of debris on the same visit.
- TreatA post-clean treatment goes on and keeps working on regrowth after we've finished.
- Show youBefore and after drone photos, so you can see the whole roof for yourself.
When is the best time?
Autumn through to spring is the ideal time, because we need the roof to be cool for the job to be done efficiently. In summer the rinse water and the chemical evaporate as soon as they go on. We can work through winter, and a little rain actually helps, but we won't go up in torrential rain because it isn't safe. It's also worth doing before you sell, or before painting, so the new paint goes onto a clean surface. For more on moss, mould and lichen, read how to get moss and lichen off your roof. Many people book a house wash and window clean on the same visit.
Solar panels and water tanks
While we're on the roof we can clean the solar panels with pure water so they run at their best over winter.
On tank water? If you harvest drinking water from the roof, the tank needs to be disconnected before we start, so the chemical can't get into it. With a post-clean treatment it needs to stay disconnected for approximately six weeks. We'll go through this with you when we quote.
“Having the before and after drone photos made a huge difference and gives you a lot of confidence that the jobs been done properly.”
Common questions
How long does a roof treatment last?
After the clean we apply a post-clean treatment that keeps working on moss, mould and lichen long after we've left, protecting the roof for around the next 12 months.
Do you go up on every roof?
Only where there's safe access. If a roof isn't safe to get onto, we'll talk you through the options.
Will I see the results?
Yes. A full roof wash gives you same-day results: it looks brand new when we leave. A roof treatment on its own looks exactly the same as when we arrived, because it takes several months for the sun, wind and rain to break down the organic matter and wash it away. We take before and after drone photos either way.
Can you clean the gutters at the same time?
Yes. Gutter clean-outs are part of a roof job, and we can wash the house and clean the windows on the same visit.
What happens with my water tank?
If you drink from a rainwater tank it needs to be disconnected so the chemical can't get in, and it needs to stay disconnected for approximately six weeks after a post-clean treatment.
