Specialising in Roof Cleaning

QAO specialises in professional roof cleaning by harnessing the power of the Cobra Air System—an advanced system that removes moss by using air, followed by a chemical treatment to prevent it returning.

Unlike traditional pressure washing, which can damage delicate roofing materials, QAO’s method uses the Cobra Air to deliver a controlled, low-pressure stream of air and cleaning agents. This system gently removes moss, algae, lichen, and debris without compromising the roof’s structural integrity.

The Cobra Air’s key advantage lies in its precision and efficiency. Its adjustable airflow and chemical application system allow QAO technicians to target problem areas without over-saturation or runoff. This results in cleaner roofs and longer-lasting outcomes, as the system not only cleans but also helps prevent future growth of organic matter.

QAO’s team is fully trained in using this specialised equipment, adhering to safety protocols and environmental regulations. By using biodegradable cleaning agents alongside the Cobra Air System, QAO provides an eco-conscious service that protects both your property and the surrounding landscape.

Whether it’s a residential, commercial, or industrial property, QAO’s tailored roof cleaning service ensures outstanding results with minimal disruption. With the Cobra Air, QAO delivers a superior clean—safely, effectively, and sustainably.
