Brisbane’s trusted cement tile roof cleaning specialists — removing lichen, moss, and algae safely using professional-grade equipment and eco-safe solutions.
★★★★★ Rated 4.8 out of 5 Based on 525+ Google reviews
If you’ve noticed dark streaking running down your roof tiles, green patches spreading across your ridgeline, or orange-brown crusts forming along your valleys — you’re not alone. It’s one of the most common maintenance issues we deal with on Brisbane properties, and it’s almost always caused by the same thing: our climate.
Brisbane is a subtropical city of nearly 2.8 million people, built around a river and exposed to over 1,000mm of annual rainfall. That combination of heat, humidity, and seasonal downpours creates ideal conditions for lichen, moss, algae, and mould to establish on cement tile roofing — particularly on south and west-facing sections with limited direct sun exposure.
Our cement tile roof cleaning service is designed specifically for Brisbane homes and the conditions they face. We use a professional adjustable bristle pressure cleaner paired with eco-safe cleaning solutions that break down biological growth at the root. The result is a clean that lasts 12 to 18 months, not 12 to 18 weeks.

BEFORESome jobs are routine maintenance. Others are urgent. If any of the following apply to your property, we recommend booking sooner rather than later.
Brisbane's property market is active and competitive. A clean cement tile roof at inspection signals a well-maintained property and directly influences buyer perception and sale price. A growth-covered roofline is one of the first things a building inspector flags.
Applying roof paint or sealant over active lichen or mould is one of the most common causes of premature coating failure. A professional cement tile clean is essential preparation before any roof restoration or reseal project.
Once biological growth establishes on porous cement tiles, it spreads rapidly across the surface and works its way into the tile material itself. Early treatment removes it cleanly — established growth causes permanent surface damage if left too long.
If your gutters are overflowing or filling faster than usual, biological matter shedding from your roof tiles is almost always the cause. A roof clean and gutter clean booked together resolves both issues in a single visit.
Brisbane's summer storm season deposits bark, leaves, and wet organic matter across rooflines that bakes on if not removed promptly — accelerating lichen and mould establishment significantly on porous cement tile surfaces.
Brisbane’s climate is what makes living here so enjoyable — but it’s also what makes biological growth on cement tile roofing an ongoing challenge for homeowners. These are the problems we deal with every single day across the city.
Brisbane's most common and most damaging cement tile roof problem. Lichen develops root-like structures that physically bond to the tile surface — early treatment removes it cleanly, while established growth can cause permanent surface pitting and staining if left untreated.
Valleys and low-drainage areas accumulate moisture and organic debris — ideal conditions for moss to establish on porous cement tiles. Moss retains moisture continuously against the tile surface and adds unnecessary weight to the roof structure over time.
These surfaces collect pollution, splash-back, and organic debris. Often the first thing a visitor notices, and the last thing homeowners think to clean.
Dark vertical streaks running down your tiles are almost always algae — once visible from street level, the growth has typically been spreading for 12 months or more and has penetrated into the tile surface.
South and west-facing tile sections with limited direct sun are the most susceptible to mould in Brisbane. Once established, it spreads to fascias, eaves, and external walls if left untreated. The same environmental factors that cause mould on exterior house walls apply directly to your cement tile roof.
Brisbane’s summer storm season regularly deposits mud, bark, and debris across rooflines and walls that bakes on if not removed promptly.
Cement tile roof cleaning in Brisbane is priced at $1.90 per m², with final pricing based on the total roof surface area, roof pitch, accessibility, and the amount of moss, lichen, algae and organic growth present.
| Home Size | Average Roof Area | Estimated Price |
|---|---|---|
| 3 Bedroom Home | 240–340m² | $450–$650 |
| 4 Bedroom Home | 340–420m² | $499–$799 |
| 5 Bedroom Home | 420m²+ | From $600+ |
Pricing is based on the actual roof surface area rather than the floor area of your home.
Most 3–4 bedroom cement tile roofs fall within this range depending on roof size and accessibility.
We safely remove moss, algae, mould and lichen using specialist roof cleaning techniques designed for cement tile roofs.
Every job is quoted individually, but a standard external house wash covers the following:

We hear it regularly — a neighbour borrowed a pressure washer, got on the roof, and got it looking clean in an afternoon. Here’s what usually happens next.
Cement tiles become more brittle with age. High-pressure lances from hardware store rentals — typically operating at 1,500–3,000 PSI — crack aged tiles, displace ridge caps, and dislodge mortar around ridgelines. The cost of tile replacement and re-bedding is significantly higher than a professional clean.
Without the adjustable bristle equipment used by professionals, lichen that has bonded to the tile surface won't fully lift — even with chemical treatments. The growth appears to disappear but regrows from the root within weeks because the base structure was never removed.
Consumer detergents don't penetrate mould spores at the root level. Without a professional mould inhibitor treatment, you're cleaning the surface — not solving the problem. Growth typically returns within weeks rather than the 12–18 months achieved with a professional treatment.
Wet cement tiles are extremely slippery. Working on a pitched roof without professional safety equipment is one of the highest-risk DIY tasks a Brisbane homeowner can attempt. Our professional equipment and safety systems eliminate most of this risk on every job.
Hiring a trained, insured professional isn’t just about a better result — it’s about protecting your roof, your tiles, and your safety.
Here’s exactly what to expect from the moment you contact us to the moment we pack up.
Call or submit a request online. We'll assess your roof size, tile condition, and soiling level, and provide a fixed-price quote with no obligation. We'll also flag any structural issues — cracked tiles, displaced ridge caps, failed pointing — that may need attention before or after the clean.
We lock in your date and give you an arrival window. You don't need to be home — just ensure gate access is available and let us know of any areas to avoid.
Our team applies a biodegradable pre-treatment solution to the full roof surface. This begins breaking down lichen, moss, and algae chemically before the main clean — improving both the result and reducing the pressure needed to remove embedded growth from the tile surface.
We use a professional adjustable bristle cleaner calibrated specifically to your cement tile type and condition. The bristle action physically agitates and lifts lichen and moss that chemical treatment alone cannot fully remove — the key difference between a professional result and a DIY surface clean.
We walk the property before leaving. If anything isn't right, we fix it on the spot. That's the guarantee.
Regular maintenance cleans, pre-sale preparation, post-storm cleans, and pre-reseal prep for cement tile homes across Brisbane and surrounding suburbs.
Rental property maintenance and scheduled packages for multiple properties. We work around tenancy schedules and minimise disruption to residents.
Office buildings, retail premises, and multi-dwelling properties with cement tile roofing. We scale our equipment and team to suit larger jobs and can work outside business hours on request.
We’re a Brisbane-based team — not a national call centre or a franchise. Every job is handled by trained, insured local operators who understand the specific challenges Brisbane’s cement tile roofs face.
Brisbane is a city that takes pride in its homes and neighbourhoods, from the classic Queenslanders in the inner suburbs to the modern rendered homes spreading through the outer growth corridors. We’ve cleaned them all, and we know what each surface type needs.
Our operators are fully insured with public liability coverage on every job. We carry the appropriate equipment for Brisbane’s residential property types, and all our cleaning solutions are formulated to meet local environmental standards, biodegradable, plant-safe, and safe for use around Brisbane waterways and stormwater systems managed by Brisbane City Council.
Cement tile roof cleaning is priced at $1.90/m². Average costs range from $450–$650 for a 3-bedroom home, $499–$799 for a 4-bedroom home, and $600+ for a 5-bedroom home. See the full price guide here.
With the correct adjustable bristle equipment calibrated to the tile surface — yes. Standard high-pressure lance washing at consumer pressure washer levels can crack aged or brittle tiles and displace ridge cap mortar. Professional equipment is calibrated specifically to avoid this while still physically lifting embedded lichen and moss.
Most standard Brisbane homes take 2 to 4 hours from setup to pack-up. Larger roofs or those with heavy lichen and moss coverage may take longer. We’ll give you a time estimate when confirming your booking.
Every 2 to 3 years is the recommended interval for most Brisbane properties. Homes near bushland, in high-rainfall suburbs, or with heavy tree coverage may benefit from an annual or bi-annual clean. Our mould inhibitor treatment extends the time between cleans by significantly slowing biological regrowth.
When performed by a trained professional using the correct adjustable bristle equipment and pressure settings for your specific tile condition, cleaning is completely safe. We’ve completed thousands of Brisbane cement tile roof cleans without a single surface damage claim.
No. As long as we have gate access and you’ve flagged any areas to avoid — open skylights, sensitive garden beds, new landscaping — we can complete the job without you present. We’ll send before and after photos on completion if requested.
