Of all the exterior cleaning jobs around a home, roof cleaning is the one we'd genuinely steer most homeowners away from doing themselves. It's not that it can't be done — it's that the risks, both to you and to the roof itself, are higher here than almost anywhere else on the property.

The Safety Risk Is Real

Falls from height are one of the most common causes of serious home DIY injury, and roofs are particularly unforgiving — steep pitches, and surfaces that get slippery fast once they're wet or covered in moss and algae. A ladder against the gutter line adds another layer of risk on top of that. This is the single biggest reason we recommend leaving roof cleaning to professionals with the right harnesses and safety equipment.

The Wrong Method Can Damage Your Roof

High-pressure water on a roof can crack or dislodge tiles, force water under the roofing membrane, and strip the protective coating off Colorbond sheeting — damage that's often more expensive to fix than the cleaning itself. Roofs need a gentler approach than most other exterior surfaces, not a more aggressive one.

Chemical Compatibility Matters

Not every cleaning product is safe on every roof type. The wrong chemical can discolour tiles, corrode Colorbond, or damage protective coatings, and it's not always obvious until the damage has already been done. Getting this wrong can end up costing far more than a professional clean would have.

Our Approach

We soft wash roofs using low pressure and treatments matched to the roofing material, so mould, moss and algae are removed at the root without the damage or safety risk of DIY methods. If you've got a Colorbond roof specifically, our Colorbond roof cleaning page covers the safe-wash approach we use in more detail. Every job is backed by a workmanship guarantee, and we carry $20M public liability insurance.
