Professional Roof Cleaning Services | Safe and Effective

---

Over time, dirt, moss, lichen, algae, and debris build up on roofs and can cause damage, shortening their life. At PSI Washing, we provide professional roof cleaning services to restore your roof’s appearance and prevent costly repairs.

We protect your roof from unnecessary wear using safe, non-damaging pressure washing techniques to remove built-up grime. Our services improve both kerb appeal and structural integrity, making your property look fresh and well-maintained.

Neglecting roof maintenance can lead to serious problems, including:

• Moss and Algae Growth –  Damages roof tiles and traps moisture.
• Water Damage and Leaks – Blocked gutters and heavy buildup can lead to water infiltration.
• Structural Weakening – Organic matter breaks down roofing materials over time.
• Energy Inefficiency – Dark, dirt-covered roofs absorb more heat, increasing cooling costs.
• Reduced Property Value – A dirty roof makes a home look neglected and unappealing.

Regular roof pressure cleaning extends the lifespan of your roof, preventing costly roof repairs or replacements.

We use a safe and effective process tailored to different roof types:

1. Inspection and Risk Assessment –  Evaluation of roof condition to select the best cleaning method.
2. Pre-Treatment – Applying a specialised roof cleaning solution to loosen and break down moss, lichen, and stains.
3. Soft Wash or Low-Pressure Cleaning – Gentle yet powerful cleaning to remove buildup without damage.
4. High-Pressure Cleaning (if required) – For tougher stains and heavy moss removal.
5. Gutter and Downpipe Flush – Ensuring proper drainage and preventing blockages.
6. Final Inspection – Checking for remaining debris and ensuring a spotless result.

 We adapt our cleaning methods to the roof material, so we safely clean tile, metal, and Colorbond roofs. 

Our professional roof cleaning services cater to all types of roofing materials:

• Tile Roofs – Clay and concrete tile roof cleaning to remove moss, lichen, and stains.
• Metal & Colorbond Roofs – Safe, non-damaging cleaning to restore original colour.
• Shingle Roofs – Gentle washing to prevent damage while removing algae growth.
• Slate Roofs – Specialised cleaning for delicate stone surfaces like slate roofs.
• Commercial & Industrial Roofs – High-efficiency cleaning for large-scale properties.

We provide expert roof cleaning for:

• Homeowners – Protect your roof and improve kerb appeal.

• Commercial & Industrial Buildings – Keep business premises clean and professional.
• Strata & Body Corporate Maintenance – Ensure shared buildings are well-maintained.

The frequency of roof cleaning depends on location, environment, and material. In most cases, we recommend a professional roof cleaning every 3-5 years.  Trees, heavy rain, or visible moss growth make more frequent cleaning necessary for your property.
