Why Treat a Roof?

Treating a roof is usually the most inexpensive roof cleaning option. If your roof already has a fair amount of growth, treating it can keep the price down in comparison to a full wash. A clean roof looks cared for, adds value, increases life of the roof and surface coatings and makes you feel great about your home or business.

How Long Does a Roof Treatment Take to Work?

Roof treatments are slow acting and work with the weather over 6 to 18 months to clean away moss, lichen and black mould.

Roof Cleaning Safety

Every year hundreds of kiwis injure themselves while working at heights. NZTS’s beginnings are based in heights safety. We have strict systems in place to ensure our safety and are familiar with running short term work safely.

Proactive Roof Treating

Treating a roof before mould and lichen starts to grow is the best way to care for your roof. Once growth occurs the damage starts happening straightaway. Treatments make a physical bond with the surface of the roof to keep mould away for up to 2 and in some cases 3 years.
