Biocide Treatment for Worthing properties
Worthing sits under Worthing Borough Council, in a coastal pocket of West Sussex where black streaking rebuilding on shaded pitches shows up on almost every roof we survey. Biocide is applied as a soft-wash spray across every pitch, saturating the tile surface so spores are killed at the root.
Why Worthing roofs need biocide treatment done carefully
Worthing sits under Worthing Borough Council, in a coastal pocket of West Sussex where black streaking rebuilding on shaded pitches shows up on almost every roof we survey. Biocide is applied as a soft-wash spray across every pitch, saturating the tile surface so spores are killed at the root. If your property is inside the BN11 area — from streets near undefined out to the edges bordering Arundel — biocide treatment done properly means matching the technique to the tile, not throwing the same recipe at every job.

Our process in Worthing

Biocide is applied as a soft-wash spray across every pitch, saturating the tile surface so spores are killed at the root.

Elevations under heavy tree shade get a second pass — that's where regrowth always starts first.

Worthing biocide treatment FAQs
Will the roof look different straight away — is that the same in Worthing?
No — biocide kills algae and lichen at the root, and the dead growth then weathers off over the following months, gradually revealing clean tile. In Worthing specifically, the exposed shingle beach and open channel funnel salt across the entire southern half of the town, so we plan the visit around that.
How often should biocide be reapplied — is that the same in Worthing?
Every three to five years is normal, sooner if your property is under heavy tree cover or close to the coast. In Worthing specifically, the exposed shingle beach and open channel funnel salt across the entire southern half of the town, so we plan the visit around that.
Do I need to clean the roof first — is that the same in Worthing?
For heavy moss and lichen, yes — biocide works best on a physically clean surface, so we usually pair it with a scrape-and-clean visit. In Worthing specifically, the exposed shingle beach and open channel funnel salt across the entire southern half of the town, so we plan the visit around that.
Do you cover the whole of Worthing and the BN11 / BN12 / BN13 / BN14 postcode?
