Roof Cleaning & Mould Removal in Cairns
Remove black mould, algae and lichen from your roof — safely and thoroughly.
Protect Your Roof from Tropical Growth
FNQ's heat and humidity create ideal conditions for black mould, red algae and lichen to take hold on your roof. Left unchecked, these organisms trap moisture, accelerate surface deterioration and make your property look neglected.
We use appropriate pressure levels and cleaning techniques for each roof type — metal, tile, or Colorbond. The result is a clean, protected roof that looks the way it should.
What You Get
- Full roof clean — mould, algae and lichen removed
- Appropriate pressure for your roof type
- Ridge caps and valleys cleaned
- Gutter lines cleared during the process
- Improved street appeal and property presentation
We service homes, units, strata complexes and commercial buildings across Cairns, Mareeba, Atherton, Mossman and surrounding areas. We often combine roof cleaning with gutter cleaning and pressure cleaning for a complete exterior clean.
Why Roof Mould Is a Problem in FNQ
Black mould and algae do more than make your roof look neglected. These organisms trap moisture against the roof surface, which accelerates deterioration of metal, tile and Colorbond finishes over time. Lichen can take root in small cracks and porous surfaces, causing physical damage as it grows. In tropical conditions like Cairns, mould can spread across an entire roof in a single wet season if left unchecked.
Regular roof cleaning removes these organisms before they cause lasting damage and helps maintain the protective coatings on your roof. It also improves the overall street appeal of your property — important for homeowners, rental property managers and anyone preparing a property for sale.
Our Roof Cleaning Process
We start by assessing the roof type and the extent of mould or algae growth. We then select the right pressure level and technique for the surface — metal roofs, concrete tiles and Colorbond panels each require a different approach. Ridge caps, valleys and gutter lines are cleaned as part of the process. We work methodically across the entire roof to ensure an even, thorough result.

Roof mould removal — Far North Queensland
Roof Cleaning FAQ
Why does my roof get black mould in Cairns?
Far North Queensland's combination of high humidity, warm temperatures and frequent rainfall creates ideal conditions for black mould, red algae and lichen to grow on roof surfaces. Shaded areas and south-facing roof sections are particularly prone. The organisms feed on moisture and organic matter that settles on the roof.
How often should a roof be cleaned in FNQ?
Most roofs in Far North Queensland benefit from a professional clean every 2 to 3 years. Properties with heavy shade, near trees, or in high-humidity locations may need cleaning more frequently. Regular roof cleaning prevents long-term damage and keeps your property looking well maintained.
Will pressure cleaning damage my roof?
Not when done correctly. We adjust pressure levels to suit each roof type — metal, tile and Colorbond all require different settings. We avoid excessive pressure that could strip protective coatings or damage tiles. Our team is experienced with all common roof types found across Far North Queensland.
