Roof Washing (Instant Results)

For an instant-result roof washing, roof surfaces are Soft Washed. First, we apply a combination of the following three cleaning agents to the roof surface: 

1. A salt-based cleaning product that removes mould and fungi, killing the spores and thereby retarding the return of green algae and black fungi.
2. A grease-cutting citrus solution that breaks down diesel fumes from nearby traffic, road dust, and BBQ splatter.
3. An environmentally friendly neutral detergent that dissolves general dirt and grime.

We then wash off the same surfaces with low-pressure water—known as a Soft Wash. As the standard for any roof wash, the roof, gutters, and spoutings are cleaned and the downpipes are flushed out with a drain snake (a plumbers tool) if/as necessary.

This service is suitable for Corrugated Iron, Colour Steel, Decromastic (pre-paint), Concrete Tile, and Butanol roofs. Where a home is on tank water, we will either disconnect and/or block off the downpipes to avoid drinking-water contamination.

Due to the necessary safety precautions involved with roof cleaning, a safety harness rigging fee will apply.

Roof Treatment (Takes up to 12 Months for the Full Result)

We spray a specifically formulated product onto the roof surface designed to kill lichen and moss. The rest is left to nature—over the next 12 months, the rain, sun, and wind gradually break down and wash or blow away the dead lichen and moss, leaving the roof looking fresh and clean.

Pictured on the right is a pressed-metal tile (metal imitation tile) roof that was partially treated using the described process.

This treatment is suitable for Corrugated Iron, Colour Steel, Decromastic, Pressed-Metal Imitation Tile, Concrete Tile, Slate Tile, Terracotta Tile, Butanol, and Cedar Shingle roofs. A small percentage (fewer than 10%) of roofs will require a booster treatment, which can be pre-booked and undertaken 12–18 months after the original treatment for a small additional cost.

Typically, a safety harness rigging fee does not apply, as we generally do not need to climb onto the roof to apply our treatment products.

NOTE: This service is not suitable for homes where water is collected from the roof for drinking—i.e., homes on tank water—due to the risk of contamination.
