The roof of this duplex at a retirement village in Nambour was in desperate need of a good clean. You can see from the photos that the grime was well and truly covering the entire metal colorbond roof. Not only was this an eyesore that detracted from the presentation of the duplex, but without proper maintenance over time the roof will become damaged due to rust and corrosion. We cleaned the roof using the Jetts surface cleaner and 100% pure water. The result speaks for itself, another job well done.
