Get answers to common questions about our roof cleaning sydney | commercial roof & gutter cleaning services.
Soft washing is a low-pressure cleaning method that relies on the chemical action of biocides and cleaners rather than high water pressure to remove biological growth. It is used on surfaces that could be damaged by high pressure — particularly Colorbond metal roofing (which can dent or have its paint coating damaged) and terracotta or glazed tiles (which can crack or have their glaze stripped). Soft wash kills lichen, algae, and moss at the root level without damaging the roofing material.
Yes. We clean Colorbond steel roofing using soft wash techniques and low-pressure rinsing that are compatible with BlueScope's Colorbond warranty requirements. High-pressure washing at close range can damage Colorbond paint coatings and may void the manufacturer's warranty — we specifically avoid this. Our biocidal treatments are safe for Zincalume and Colorbond substrates.
Yes. Gutter clearing is included as part of our standard roof cleaning service. Blocked gutters are a common consequence of organic growth and debris on roofs, and clearing them is essential to ensure proper stormwater drainage. We clear leaf matter, moss, dirt, and blockages from all gutters and downpipes and check for proper flow before completion.
Most commercial roofs in Sydney's environment benefit from cleaning every 2–3 years to prevent significant biological growth buildup. Buildings in tree-lined areas, near the coast, or in humid environments may require annual cleaning. Flat roofs with drainage systems should be inspected and cleared more frequently — we recommend a minimum of annual inspections for flat commercial roofs.
Yes. All Pro Clean Corp staff performing roof cleaning hold current Working at Heights certification. We use appropriate fall arrest equipment, safety harnesses, roof anchor systems, and elevated work platforms (EWPs) where required.
