Roof Treatment Lower Hutt
The Hutt Valley traps moisture and northerly rain, so moss, lichen and mould take hold on roofs faster than drier regions. North-facing slopes across Naenae, Avalon and Wainuiomata often show green streaks within a year of the last clean.

Our biocide roof treatment is spray-and-leave — no pressure washing that strips Colorsteel coatings or damages concrete tiles. The slow-acting formula kills organic growth at the root over 3–6 months, with results continuing to improve for up to a year.
We treat concrete tile, long-run iron and Colorsteel roofs across the full Hutt Valley. Pair roof treatment with gutter clearing in one visit for better drainage and value.
