Why soft wash
Blasting it off
buys you a season.
High pressure clears the growth but takes the surface of your roof with it. A rougher roof holds more water, so the growth comes back faster than before.
Soft wash vs pressure cleaning.
| Cherry soft wash | Pressure cleaning | |
|---|---|---|
| Pressure | ✓ Low — sprayed on | High — blasted off |
| Tile surface | ✓ Left intact | Stripped and roughened |
| Kills at the root | ✓ Yes | No — regrows from what's left |
| Keeps working after | ✓ Yes, for an extended period | No |
| Risk of leaks | ✓ Minimal | Water forced under flashings |
| Foot traffic | ✓ Minimal, from the roofline | Heavy, across the whole roof |
Anyone can strip a roof in an afternoon. Nobody can undo the damage.
Low pressure, not high
Sprayed on, never blasted. Your roof's surface is left exactly as we found it.
Kills it at the root
The biocide penetrates the growth so it can't simply regrow from what's left behind.
Keeps working after we leave
Stays active on the surface, so the roof keeps cleaning itself with every rain.
Minimal foot traffic
We work from the roofline wherever possible — less weight, fewer cracked tiles.
What we're treating
It's alive, and it's holding on.
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.
