Frequently Asked Questions

No. Soft washing operates at very low pressure (typically under 100 psi — the same as a garden hose). It cleans by killing algae and moss with biocide, not by force. This is unlike high-pressure jet washing, which can strip the protective glaze off concrete tiles and crack ridge mortar.

With our 5-year biocide treatment, most Hampshire roofs stay visibly clean for 5–7 years. Roofs heavily shaded by trees or facing north tend to be on the shorter end; south-facing roofs on the longer end.

Almost never. Our soft wash system uses extended carbon-fibre poles that reach most roofs from ground level. We only suggest scaffolding for chimney repairs or unusually high properties (4 storeys+).

Most domestic roof cleans are completed in 4–8 hours. Larger detached properties or roofs with heavy moss may take a second day.

Yes. We guarantee the biocide treatment for 5 years — if the roof shows visible regrowth in that period, we re-treat free of charge. Payment is only taken after you’re happy with the result.
