Drone Roof Spraying — Moss, Mould & Lichen Treatment Without the Scaffolding

Moss, mould, and lichen on commercial and rural roofs cause real damage — deteriorating cladding, blocked gutters, and accelerated wear that costs significantly more to fix than to prevent. Wysper's drone roof spraying delivers effective, no-contact treatment for packhouses, barns, sheds, and commercial buildings across the Bay of Plenty. No scaffolding. No workers on your roof. No unnecessary risk.

The Hidden Cost of an Untreated Roof


Moss and lichen don't just look bad — they actively attack your roofing material. Moss retains moisture against the surface, accelerating rust and corrosion on steel cladding. Lichen etches into coatings and concrete tiles, creating ingress points for water. Left long enough, what could have been a simple spray treatment becomes a roof repair or replacement job.

For packhouses and commercial buildings, there's also a compliance and presentation angle. Client visits, food safety audits, and rural worker health standards all put a premium on maintaining clean, well-kept facilities. Drone roof treatment is the most efficient way to stay on top of it.

Why Drone Roof Treatment Makes Sense

• Zero foot traffic on the roof — no risk of denting, cracking, or voiding your roof warranty

• Faster than traditional methods on large commercial, packhouse, or barn roofs

• Safe for Colorsteel, concrete tile, long-run steel, and other common NZ roof types

• Fully licensed operators — CAA certified, commercially insured

• Local Bay of Plenty team — fast response and flexible scheduling around your operations

• Effective on packhouses, cool stores, barns, sheds, implement buildings, and processing facilities

Frequently Asked Questions

  • Yes. Our drone application puts product only where it's needed and eliminates foot traffic on the roof surface — which is actually the primary cause of damage during traditional roof treatments. We use products appropriate for common NZ roofing materials.

  • Most treatments provide visible results within 4–8 weeks as moss and lichen die back, with protective effects lasting 12–24 months depending on your local environment, rainfall, and roof aspect. We can discuss a maintenance schedule to keep your roof in top condition year-round.

  • This depends on the product used, application rate, and timing. We'll work with you to plan spraying for the right window in your season. In many cases, treatment can be scheduled during low-risk periods without affecting your crop program.

  • Absolutely — large roofs are where drone treatment offers the greatest efficiency advantage over traditional methods. We can complete treatment on large packhouses or commercial facilities in a fraction of the time it would take a manual crew, and at significantly lower cost once scaffolding is removed from the equation.

  • In most cases, no. The drone operates externally above the roof. We'll discuss any specific requirements based on the product used and proximity to ventilation, skylights, or sensitive areas during the quoting stage.
