Flying foxes — grey-headed and little red flying foxes — are common and protected species across South East Queensland, roosting in suburban trees throughout Redlands, Cleveland, Wynnum, Manly and Brisbane. Their droppings fall on the roofs, gutters and exterior walls of homes below roost sites. Bat guano is highly acidic — more so than bird droppings — and causes accelerated deterioration of roofing materials and paint if left untreated. It stains concrete tiles, colorbond and render a distinctive dark brown or black that becomes increasingly difficult to remove the longer it remains. Regular professional cleaning is one of the most important maintenance tasks for properties beneath flying fox roost sites across SEQ.
Bat guano contains uric acid and other compounds that are highly corrosive to roofing materials. On concrete tiles, the acid etches into the tile surface. On colorbond, it degrades the paint coating. In gutters, heavy accumulation can block water flow and accelerate rust in steel gutters. The damage compounds significantly over time — early treatment is always cheaper than delayed treatment.
Bat droppings are typically darker, more liquid when fresh and more acidic than common bird droppings. They tend to accumulate in concentrated zones directly beneath roost trees. Dark staining concentrated below nearby trees is a strong indicator of bat droppings.
We use professional grade soft wash solution that breaks down organic compounds in bat guano, kills associated biological growth, and rinses the residue at low pressure. On colorbond roofs, pH-appropriate solutions protect the factory paint coating. Full protective equipment is worn during treatment.
Properties beneath active flying fox roost sites typically benefit from annual cleaning. The accumulation rate depends on colony size and proximity of roosting trees to your roof.
