Your roof is constantly exposed to New Zealand's changing weather conditions. Over time, moss, mould, lichen and algae can take hold, trapping moisture and accelerating roof deterioration.
Our professional roof treatment process targets biological growth at its source, helping to:
Improve your roof's appearance
Prevent moisture retention
Reduce surface deterioration
Protect your property's value


Unlike pressure washing alone, our treatment process continues working long after application.
Our team carefully assesses your roof's condition before recommending the most suitable treatment method, ensuring effective results without unnecessary damage to roofing materials.
The Moss Crew provides roof treatment services for properties of all sizes across Hawke's Bay. We regularly work with:
Wineries & Vineyards
Schools & Educational Facilities
Food Processing Facilities
Property Management Companies
Residential Homeowners







Most treatments continue working for several months after application. Longevity depends on roof type, weather conditions, surrounding vegetation and the level of existing growth.
No. We use treatment methods designed to be effective while remaining suitable for your specific roofing material. Our team assesses every roof before starting work.
Results vary depending on the amount of growth present. Many customers notice improvements within weeks, with continued cleaning occurring naturally over time.
Early moss, algae and lichen growth often begins before it becomes visible from the ground. Regular treatment can help prevent larger problems and reduce future maintenance costs.
