Roof Cleaning
Professional Pressure Cleaning Specialists | Sunshine Coast
Surface Co. specialises in professional roof cleaning using safe soft wash techniques for tile and metal roofs across the Sunshine Coast. Roof cleaning is essential maintenance that extends roof lifespan, prevents water damage, and improves your home's appearance. Unlike pressure washing which damages tiles and causes leaks, our soft washing method kills organic growth without any risk to your roof. As professional pressure cleaning and roof cleaning specialists, we understand that different surfaces require different approaches - and roofs must never be pressure washed with high pressure.
Our Method: Soft Washing
Roof cleaning MUST use soft washing, never high-pressure cleaning. High-pressure washing damages roof tiles, forces water under tiles causing leaks, and voids warranties. Our professional soft wash method uses low pressure with specialised biocidal treatments that kill moss, lichen, and algae at the root. The organic growth then breaks down naturally over following weeks, leaving your roof clean without any risk of damage. This is the only method recommended by roofing manufacturers and is the standard practice for professional roof cleaning companies.

Safety & Quality Assurance
Frequently Asked Questions
Why don't you use pressure washing for roof cleaning?
High-pressure washing is dangerous and damaging for roofs. It forces water under tiles causing leaks, damages tile coatings, breaks tiles, and voids most roof warranties. Professional roof cleaning companies use soft washing with biocidal treatments because it's safe and effective. Our soft wash method kills organic growth without any pressure damage, which is why it's recommended by roofing manufacturers. Anyone offering "pressure cleaning" for roofs is using outdated, damaging methods.
How does soft washing kill moss and lichen if you're not pressure washing?
Our professional biocidal treatments kill moss, lichen, and algae at the root level chemically, not mechanically. After treatment, the dead organic matter breaks down naturally over 2-4 weeks with rain and sun exposure. This provides longer-lasting results than pressure washing because we've killed the growth at its source. You'll notice gradual improvement over the following month as the roof continues to clean itself.
Will roof cleaning stop my roof from leaking?
If leaks are caused by blocked valleys, gutter overflow, or moss holding water, then yes, cleaning will help. However, if leaks are due to broken tiles, failed flashings, or deteriorated roof structure, cleaning won't fix these - repairs are needed. We inspect roofs during cleaning and will advise if we spot any damage or concerns that need professional roofing attention.
How long do roof cleaning results last?
With our biocidal treatment, most roofs remain clean for 2-3 years before significant regrowth occurs. This varies based on location (shaded vs full sun), rainfall, and nearby vegetation. Regular maintenance every 2-3 years keeps your roof in optimal condition and prevents heavy buildup that's harder to treat.
Can you clean Colorbond and metal roofs?
Yes. Metal roof cleaning uses the same safe soft wash approach to remove oxidation, dirt, and organic growth. We use specialised treatments safe for metal roofing that restore appearance without damaging the protective coating. Many Sunshine Coast metal roofs benefit significantly from professional cleaning, especially in coastal areas with salt exposure.
