black streaking rebuilding on shaded pitches
Frequently reported by owners near Emsworth Quay.
lichen re-establishing on ridge tiles

Our process in Emsworth
- 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.

Emsworth biocide treatment FAQs
How often should biocide be reapplied — is that the same in Emsworth?
Every three to five years is normal, sooner if your property is under heavy tree cover or close to the coast. In Emsworth specifically, onshore south-westerlies off the harbour salt the entire west of the town every winter, so we plan the visit around that.
Is biocide safe for pets and plants — is that the same in Emsworth?
Yes — the products we use are designed for domestic roof application and are safe once dry, though we cover sensitive planting during the spray itself. In Emsworth specifically, onshore south-westerlies off the harbour salt the entire west of the town every winter, so we plan the visit around that.
Will the roof look different straight away — is that the same in Emsworth?
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 Emsworth specifically, onshore south-westerlies off the harbour salt the entire west of the town every winter, so we plan the visit around that.
