Petersfield biocide treatment done the right way
We cover Petersfield on biocide treatment from our base in Petersfield, and we know the town well enough to price it properly rather than guess. The town centre mixes tile-hung Georgian frontages with clay-tiled Victorian terraces, while newer estates on the fringes use concrete interlocking tiles that hold moss on the shaded north pitches.
Why Petersfield roofs need biocide treatment done carefully
We cover Petersfield on biocide treatment from our base in Petersfield, and we know the town well enough to price it properly rather than guess. The town centre mixes tile-hung Georgian frontages with clay-tiled Victorian terraces, while newer estates on the fringes use concrete interlocking tiles that hold moss on the shaded north pitches. That's why one street off The Square might need a full scrape-and-treat while another needs only a light soft-wash pass. We also handle Liss and Liphook on the same trips, so trades don't sit idle between jobs.

Our process in Petersfield
- 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.

Every three to five years is normal, sooner if your property is under heavy tree cover or close to the coast.
