Why Havant roofs need biocide treatment done carefully

What we see on Havant roofs
Havant's proximity to Langstone Harbour means the majority of concrete-tile roofs suffer heavily from salt-fed lichen and streaking on south-west elevations.
algae returning within months of a manual clean
Common on 1930s semis where prevailing weather sits against the pitch.
black streaking rebuilding on shaded pitches
Frequently reported by owners near Havant town centre.
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 A27 where road dust binds with damp.
Our process in Havant
- 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.

Havant biocide treatment FAQs
Is biocide safe for pets and plants — is that the same in Havant?
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 Havant specifically, onshore winds off langstone and chichester harbours drive salt deep into roof surfaces year-round, so we plan the visit around that.
Will the roof look different straight away — is that the same in Havant?
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 Havant specifically, onshore winds off langstone and chichester harbours drive salt deep into roof surfaces year-round, so we plan the visit around that.
Do I need to clean the roof first — is that the same in Havant?
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 Havant specifically, onshore winds off langstone and chichester harbours drive salt deep into roof surfaces year-round, so we plan the visit around that.
