How often should the roof be cleaned?

Every 3–5 years on most South West roofs. Shaded north pitches and houses under heavy tree cover are at the shorter end.

Is walking on the tiles going to crack them?

Only careless walking does. We use roof ladders that spread the load across multiple battens, and we only foot-traffic where access actually requires it.

Will it affect the warranty on a new roof?

Manufacturer warranties on modern tiles specifically allow biocidal softwash. Anything else, we'd check the warranty document before quoting.

What stops the moss coming straight back?

Mechanical removal followed by a full softwash. The softwash kills the spores so the next growth cycle starts from much further back.

How long does it take?

Most three-bed semis are a single day, larger or more complex roofs are two. We don't leave a roof half-treated overnight.
