Drive through any Mackay suburb and you'll see it: roofs with black streaks, green patches and dark stains. It's not dirt — it's mould, lichen and algae, and our warm, wet, humid climate gives it everything it needs to thrive.
Once it takes hold, it doesn't just sit there looking ugly. Left alone, it slowly breaks down your roof surface.
Why Mackay roofs cop it worse
- Humidity — moisture in the air feeds mould and algae year-round
- Wet season rain — keeps roofs damp for weeks at a time
- Shade from trees — overhanging branches stop the roof drying out
- Leaf litter in valleys and gutters — traps moisture against the surface
What it's doing to your roof
Lichen and mould don't just sit on the surface — their roots work into tile coatings and mortar, slowly breaking them down. That shortens the life of your roof and can lead to bigger repair bills down the track.
There's also the street appeal factor. A stained roof makes the whole house look tired — which matters if you're thinking about painting, selling, or just want to enjoy your home again.
What a professional clean actually does
Every roof is different, so we assess the condition first. Where needed, we apply a mould and lichen treatment, then pressure clean the entire roof to remove built-up dirt, mould, lichen and debris — working carefully across areas with heavier build-up before a final rinse and inspection.
The result is a roof that looks significantly cleaner and refreshed, adds value to your home, and stays cleaner for longer. Most treatments last 2 to 5 years depending on your roof material, surrounding trees and weather exposure.
Is it safe for my roof?
Yes — when it's done properly. We use low-pressure washing for most roofs to avoid damaging tiles or pointing, and only use higher pressure where the surface calls for it. That's the difference between a professional clean and a weekend with a hired pressure washer.
