What's living on your roof
Moss
Holds water against your tiles like a sponge, so the wet parts of your roof stay wet all year.
Lichen
Anchors into the surface and secretes acid that slowly bores into your tiles.
Algae
Starts on the shaded faces and spreads — the black streaks running down your roof.
Mould
Follows the damp the others leave behind and moves wherever water sits.
They came in on the weather and they won't leave on their own. All four get the same treatment.
How it works
01
Tell us where you are. We assess your roof and arrange a site visit where needed.
02
One flat price for the whole roof, in writing, before you commit to anything.
03
A low-pressure soft wash, applied from the roofline. We photograph it on the day.
04
The growth dies at the root and washes away over the following months.
The results
Nobody went back up in between. The treatment kept working and the weather did the cleaning.


Why soft wash
High pressure clears the growth but takes the surface of your roof with it — cracked tiles, damaged pointing, stripped coatings and water forced under the flashings. A rougher roof holds more water, so the growth comes back faster than before.
Anyone can strip a roof in an afternoon. Nobody can undo the damage.
Sprayed on, never blasted. Your roof's surface is left exactly as we found it.
The biocide penetrates the growth so it can't simply regrow from what's left behind.
Stays active on the surface, so the roof keeps cleaning itself with every rain.
We work from the roofline wherever possible — less weight, fewer cracked tiles.
Every roof type
Removes stubborn black stains without touching the glaze.
Breaks down thick moss and lichen safely, over months.
Non-corrosive and safe on coatings — nothing stripped.
Gentle on sheeting where pressure cleaning would scratch.

FAQ
We apply a biocide soft wash at low pressure. It soaks into the growth and kills it at the root. Over the following months the dead moss, lichen and algae loosen and the rain and wind carry it away.
Typically between 3 and 18 months, depending on how heavy the growth is and the weather. On the day your roof will look much the same — that's normal.
High pressure strips the surface off your tiles, cracks tiles, damages pointing and drives water under the flashings. A rougher roof then holds more water, so the growth comes back faster.
Yes. We apply it carefully at low pressure and protect surrounding areas. We just ask that pets are kept inside while we work.
No. We work from the outside and don't need to come into the house. We just need safe access to the property.
Light rain after application is fine once the treatment has had time to absorb. If heavy rain is forecast, we'll reschedule at no cost.
Spores land on every roof eventually. The treatment keeps working on the surface for an extended period, and staying on top of it is far easier than the first treatment.
