Is Your Mandurah Roof Covered in Black Streaks or Moss?
Those black streaks aren't just dirt—they are a type of algae called Gloeocapsa Magma that eats away at your roofing materials. Combined with Mandurah's coastal humidity, moss and lichen can quickly take hold, lifting tiles and causing long-term damage.
Why High Pressure is Dangerous: Blasting a roof with high-pressure water can strip the protective granules off shingles, crack aged tiles, and force water under the laps, leading to expensive internal leaks.
The Soft Wash Difference: At Peel Soft Wash, we use a specialized biodegradable solution that kills moss and algae at the root. We then use a low-pressure rinse (no stronger than a garden hose) to wash it away, leaving your roof pristine and damage-free across Mandurah and the wider Peel Region.
- ✓ Extends the life of your roof tiles & Colorbond
- ✓ Kills algae spores to prevent rapid regrowth
- ✓ Zero risk of pressure-related water intrusion
- ✓ Enhances curb appeal and property value
- ✓ Safe for gardens, pets & surrounding plants
Roof Cleaning for All Mandurah & Peel Region Roof Types
Different materials require different care. We are trained for both.
Concrete & Terracotta Tile Roofs
Common in: Halls Head, Meadow Springs, Erskine, and Pinjarra.
Older tiled roofs in the Peel region are prone to Black Lichen and Moss. These organisms dig their roots (rhizoids) into the tile, making them brittle.
Our Solution: We use a biological treatment that kills the lichen root system, allowing it to weather off naturally or be gently rinsed, preserving your ridge capping.
Colorbond & Metal Roofing
Common in: Lakelands, Madora Bay, Dawesville, and Austin Cove.
Colorbond is tough, but salt spray from the Indian Ocean causes oxidation and chalkiness if not washed. Manufacturers often require regular wash-downs to maintain your warranty.
Our Solution: A soft exterior wash that removes salt buildup, spider webs, and dust without scratching the paint coating.
Our 3-Step Roof Washing Process
Maximum clean, zero damage.
Inspect & Protect
We begin with a safety inspection of your roof and gutters. We then pre-drench your surrounding garden and plants with fresh water to ensure they stay protected during the clean.
Soft Wash Application
We apply our custom cleaning solution using a low-pressure system. This treatment dwells on the surface, biologically killing moss, lichen, and algae down to the spores.
Gentle Rinse & Gutter Clear
Finally, we perform a gentle, low-pressure rinse from the ridge down to the gutters. Your roof is left looking like new, and your gutters are cleared of any loosened debris as part of our standard service.

Roof Washing FAQs — Mandurah & Peel Region
Common questions from Peel Region homeowners about professional roof cleaning.
How much does roof washing cost in Mandurah?
Roof washing in Mandurah typically starts from $400–$500 for a standard single-storey home, depending on roof size, pitch, and the severity of moss or lichen growth. Double storey homes start from around $600. We provide free, fixed-price quotes with no surprises — call 0435 151 877 or fill out our online form.
How often should I have my roof washed in the Peel Region?
Most Mandurah homes benefit from a professional roof clean every 2–3 years. Coastal properties in suburbs like Madora Bay and Dawesville — where salt spray accelerates algae growth and Colorbond oxidation — may need cleaning every 12–18 months to prevent long-term damage.
Is soft washing safe for all roof types?
Yes. Soft washing uses low pressure — no stronger than a garden hose — combined with a biodegradable cleaning solution. It is completely safe for concrete tiles, terracotta tiles, and Colorbond roofing. Unlike high-pressure washing, it will not crack aged tiles, strip granules, or force water under roof laps.
Will roof cleaning damage my gutters or garden?
No. Before we begin, we pre-drench all surrounding plants and garden beds with fresh water. Our biodegradable solution is safe once diluted and rinsed. We also clear any loosened debris from gutters as part of our standard process at no extra charge.
Can you remove black streaks from my Colorbond roof?
Yes. Black streaks on Colorbond are typically caused by algae, salt oxidation, or coastal dust — very common in the Peel Region. Our soft wash treatment dissolves these at the source without scratching the paint coating, restoring your roof's appearance and protecting your manufacturer's warranty.
