Why Melbourne roofs go black, green and grey
Melbourne's mix of humid summers, cool damp winters and tree-lined streets in suburbs like Brighton, Camberwell and the Dandenong foothills creates ideal conditions for gloeocapsa magma (the algae behind those black streaks), moss and lichen. These organisms take hold in the porous surface of terracotta and concrete tiles, spreading spores with every rain event. Left untreated, moss lifts tiles and holds moisture against the roof deck, while lichen's root structure eats into the tile surface. Colorbond roofs get dirt staining and algae in valleys and low-pitch sections that never fully dry out.
Soft wash, not high pressure
We use a low-pressure soft wash system combined with a biodegradable cleaning solution that breaks down organic growth at the root. High-pressure water blasting looks dramatic but strips the protective glaze off concrete tiles, drives water under laps and voids most manufacturer warranties. Our method is the same approach warranty providers recommend, because it cleans without physically damaging the tile surface, ridge capping or pointing.
Terracotta and concrete tile roofs
Terracotta and concrete tiles (Boral, CSR Monier, Bristile) each need different treatment strengths. Terracotta is more porous and holds onto lichen roots, so it often needs a longer dwell time before rinsing. Concrete tiles can be re-coated after cleaning to restore colour and add a protective sealant layer. We assess tile type, age and porosity on-site before quoting, because a heavily lichen-affected roof in a shaded, tree-covered street takes longer than a north-facing roof with light dust.
Colorbond and metal roof cleaning
Colorbond and other steel roofs need a gentler approach — no abrasive brushing, no acidic chemicals that can strip the factory paint or void your BlueScope warranty. Our soft wash removes algae staining, dirt streaking and bird droppings from valleys, gutters and low-pitch sections without touching the paint system. We rinse thoroughly to clear residue from gutters and downpipes so it doesn't sit and cause corrosion later.
Black streak and algae treatment
Those dark streaks running down from ridge caps aren't dirt — they're a living algae colony (gloeocapsa magma) that feeds on the limestone filler in tiles. Pressure washing knocks the visible growth off but leaves the roots, so streaks return within months. Our treatment kills the algae at the root and slows regrowth, so you're not paying for the same clean again next year.
Harnessed, insured crews
All our roof cleaning is carried out by harnessed crews trained for steep pitches, two-storey homes and heritage roofs. We are fully insured and follow proper height safety procedures on every job — no ladders leaned against gutters, no standing on ridge capping without anchor points. We also protect gardens, pools and outdoor furniture below with tarps and low-runoff technique before we start.
What's included in a roof clean
A standard clean covers the full roof surface, valleys, ridge capping and ties, plus a gutter flush to clear debris washed down during the process. We photograph before and after so you can see the result, and we check for loose or cracked tiles, broken ridge capping and rusted screws while we're up there — issues we flag even if they're outside the scope of the clean.
Roof cleaning cost in Melbourne
Most residential roof cleans in Melbourne run from around $4 to $8 per square metre depending on roof pitch, access, tile type and how heavy the moss or lichen coverage is. A single-storey 200m² roof with moderate growth typically comes in between $800 and $1,400. Steep pitches, multi-storey access, heavy lichen or a re-coat push it higher. We give a fixed price after inspecting photos or the roof in person — no surprises on the day.
Servicing all Melbourne suburbs
We clean roofs right across Melbourne, from bayside suburbs like Brighton and Sandringham to the leafy east (Camberwell, Balwyn, Box Hill) and out to the Dandenongs and Mornington Peninsula. Tree-heavy, shaded streets in these areas tend to carry the heaviest lichen and moss loads, so if your roof backs onto established trees it's worth getting checked every 2 to 3 years before growth takes hold.

Roof Cleaning FAQ
Answers before you ask.
Will soft wash roof cleaning void my roof warranty?+
No — soft washing is the method most tile and Colorbond manufacturers recommend. It's high-pressure water blasting that typically voids warranties, because it strips protective coatings and can crack tiles or damage paint finishes. We use low-pressure application specifically to stay warranty-safe.
How much does roof cleaning cost in Melbourne?+
Most jobs cost between $4 and $8 per square metre, so a typical 200m² single-storey roof runs $800 to $1,400. Price depends on pitch, access, tile type and how heavy the moss, lichen or algae growth is. We provide a fixed quote after assessing photos or inspecting on-site.
Can you clean Colorbond roofs without damaging the paint?+
Yes. We use a gentler soft wash formulation for Colorbond and other steel roofs — no abrasive brushing and no harsh acidic chemicals that strip the factory paint system. It removes algae staining and dirt without affecting the coating or your BlueScope warranty.
Do you remove moss or just clean the surface dirt?+
We remove moss, lichen and black streak algae from the root, not just the visible growth on top. Pressure washing knocks growth off the surface but leaves roots intact, so it grows back fast. Our treatment kills the organism and slows regrowth.
Is it safe for my garden, pool and gutters?+
Yes. We use biodegradable cleaning solutions and tarp off gardens and outdoor areas below the work zone. We also flush gutters and downpipes after cleaning so residue doesn't sit and cause corrosion or affect rainwater tanks.
How often should I get my roof cleaned?+
Every 2 to 3 years is typical for most Melbourne homes, though shaded, tree-lined properties with heavy moss or lichen growth may need it more often. Regular cleaning stops growth from taking hold and getting into the tile surface, which is cheaper than remediating a badly affected roof later.
Are your crews insured and safe on steep roofs?+
Yes. Our crews are harnessed and trained in height safety for steep pitches, two-storey homes and heritage roofs, and we are fully insured for public liability. We use proper anchor points rather than standing on ridge capping or leaning ladders on gutters.
