Roof pressure cleaning is a process where water under controlled pressure is used to lift and remove surface build-up including dirt, organic growth like moss, mould, lichen, and environmental stains. It is more intensive than soft washing and intended for tougher grime. Before pressure cleaning, surfaces are assessed, loose components secured, and cleaning methods matched to roof material to prevent damage.
Restoring a roof’s colour and brightness by removing embedded stains and biological growth.
Improving water runoff and reducing ponding by cleaning gutters, valleys, and channels.
Cutting down on moisture retention that causes decay in roof underlays, timber, or insulation.
Enhancing UV reflection on metal and light coloured roofs, reducing heat absorption.
Making inspections easier and safer by clearing away obstacles and build-up.
Accumulated moss or grime holds moisture and can degrade tiles, metal sheeting, and coatings over time, leading to cracks, rust or leak paths.
Dirt and organic growth conceal potential problems such as broken flashings, loose tiles, or worn seals. Removing the build-up exposes these so they can be fixed early.
Clean roofs reflect heat more effectively, which helps keep homes cooler during hot weather and lowers strain on cooling systems.
A clean roof makes a big difference visually boosting kerb appeal, improving property value, and giving your home a well-maintained, cared-for look.
Initial Roof Assessment & Safety Check
We inspect the roof surface, material type, slope, flashings and underlay condition, and plan safe access.
Pre-Cleaning & Debris Removal
Remove leaves, twigs, and loose organic matter by hand or brush so pressure washing doesn’t push debris under tiles or into roof valleys.
Choosing Correct Pressure & Technique
We select pressure level and nozzle type suited to roof material (tile, metal, etc.) so cleaning is effective without causing damage.
Professional Pressure Washing & Treatment
Using controlled pressure, we clean algae, moss, mould and stains. Optionally apply treatment to slow regrowth.
Rinsing & Drainage Clearing
Clean water flow paths are flushed; gutters, downpipes and valleys cleared so rainwater flows away properly.
Final Check & Preventive Recommendations
We inspect surface condition, flashing, seal integrity; offer advice on intervals for repeat cleaning, prevention of regrowth, and protecting coatings.
Concrete & Terracotta Tiles
Deep cleaning to remove moss, mould and restore colour while respecting tile glaze and avoiding damage.
Metal Roofing (Colorbond, Zincalume, Galvanised)
Rust‐prone and reflective surfaces cleaned carefully, using rust inhibitors and proper pressure settings to preserve coatings.
Composite & Synthetic Roof Panels
Gentler pressure and compatible cleaning agents used for composite materials to avoid warping or chemical damage.
Flat & Low-Slope Roofs
Particular attention to drainage and run-off; cleaning ensures blocked sections, ponding or membranes are addressed.
You may need roof pressure cleaning if you see:
Dark staining, moss, lichen, or algae spreading across roof surfaces
Poor water runoff, overflow in gutters, or pooling water after rain
Fading or dull colour, especially on lighter roofs or metal sheeting
Slippery surfaces or debris build-up on roof ridges, valleys or eaves
Noticeable growths or airborne spores in attic or ceiling spaces
Increase in cooling costs or overheating inside rooms near roof

If done incorrectly, yes. But we use correct pressure settings, safe nozzles and follow material-specific guidelines to avoid damage.
Typically every 2-3 years, but may be sooner in coastal or damp zones, or if roof is shaded heavily.
Yes, when using biodegradable agents, capturing runoff properly, and avoiding harmful chemicals.
It helps by exposing hidden issues and removing obstacles to water flow, but leaking components must be repaired separately.
Not always. Cleaning is often sufficient, though restoration or painting may be recommended depending on roof age or surface wear.
