Longer-Lasting Roof Performance

In Cairns’ humid, coastal conditions, organic growth bonds to roof surfaces, traps moisture and hastens coating breakdown.

Frequently Asked Questions

How does mould and lichen affect a roof over time?

Mould, lichen, and algae can trap moisture against roofing materials, which may contribute to premature wear and deterioration over time. On tiled roofs, growth can lift or weaken tiles, while metal roofing may experience staining or corrosion if contaminants are left untreated. Regular cleaning helps reduce build-up that can affect both appearance and roof condition.

Can pressure cleaning a roof cause damage?

Roof cleaning can cause damage if incorrect pressure or unsuitable methods are used. High pressure may crack tiles, strip protective coatings, or force water into roofing cavities. Different roof materials require different cleaning approaches, which is why pressure settings, equipment, and treatment methods should be suited to the roof type and condition.

How often should a roof be professionally cleaned?

The frequency of roof cleaning depends on environmental conditions such as tree coverage, moisture, shade, and local climate. Roofs in humid or heavily shaded areas often develop mould and lichen more quickly and may require cleaning more regularly. Many properties benefit from professional roof cleaning every few years to reduce build-up and maintain the roof’s condition.
