Most roofs start from around $380 for smaller homes up to ~120 m², with larger properties from ~$520. Get an exact figure with our free instant online estimate — no call-out fee.
No. We apply a biocide spray-and-leave treatment that kills moss, lichen and mould at the root over several months — without stripping coatings or voiding warranties.
You'll typically notice moss and lichen dying back within 3–6 months. Full results continue to improve over 12 months as rain washes away dead organic matter.
We recommend reapplication every 18–24 months. Wellington's moisture and coastal air mean roofs collect organic growth faster than drier regions.
