Biocide Treatment for Bognor Regis properties
Bognor Regis sits under Arun District 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 Bognor Regis roofs need biocide treatment done carefully
Bognor Regis sits under Arun District 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 PO21 area — from streets near undefined out to the edges bordering Chichester — biocide treatment done properly means matching the technique to the tile, not throwing the same recipe at every job.

What we see on Bognor Regis roofs

algae returning within months of a manual clean
Common on Victorian seafront terraces where prevailing weather sits against the pitch.
black streaking rebuilding on shaded pitches
Frequently reported by owners near Bognor Pier.
lichen re-establishing on ridge tiles
Especially where mature trees over the coastal area shed onto the roof.
green film across the whole slope after wet winters
Typical of properties served by the A29 where road dust binds with damp.
Our process in Bognor Regis
- 1
Biocide is applied as a soft-wash spray across every pitch, saturating the tile surface so spores are killed at the root.
- 2
We time treatment for a dry weather window so the biocide has hours on the tile before any rain washes it off.
- 3
Elevations under heavy tree shade get a second pass — that's where regrowth always starts first.
- 4
We don't cheat by watering biocide down; the strength we quote is the strength we apply.

Bognor Regis biocide treatment FAQs
Will the roof look different straight away — is that the same in Bognor Regis?
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 Bognor Regis specifically, salt-laden winds attack every south-facing pitch and eat into mortar bedding, so we plan the visit around that.
How often should biocide be reapplied — is that the same in Bognor Regis?
Every three to five years is normal, sooner if your property is under heavy tree cover or close to the coast. In Bognor Regis specifically, salt-laden winds attack every south-facing pitch and eat into mortar bedding, so we plan the visit around that.
Do I need to clean the roof first — is that the same in Bognor Regis?
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 Bognor Regis specifically, salt-laden winds attack every south-facing pitch and eat into mortar bedding, so we plan the visit around that.
