Roof Cleaning for Coastal WA Homes
Safe roof cleaning across Perth and the WA coast. We remove moss, lichen and grime from tile, metal and Colorbond roofs without the high-pressure damage that cracks tiles and strips surfaces. Part of our pressure washing & cleaning service.
Why coastal roofs grow so much moss and lichen
Moss and lichen need moisture and something to cling to, and coastal roofs offer both. The humidity, the salt that holds moisture on surfaces, and the shaded slow-drying sections of a roof all feed growth, and weathered porous tiles give it a grip. So coastal roofs green up faster and more heavily than inland ones. Left alone, moss holds water against the roof surface, works into and lifts tiles, breaks down the surface over time, and washes into gutters and blocks them.

What we clean, and how
Assess the roof
We look at the growth, the roof type and condition, and whether cleaning alone is right or whether a fuller restoration is needed. We'll tell you honestly.
Clean safely
Growth, grime and salt removed using soft wash and low-pressure methods matched to the material, effective on the moss and lichen, safe on the tiles and coating.
Clear the gutters
Roof growth ends up in the gutters; clearing the run-off path is part of protecting the roof and drainage.
Advise on the cycle
We tell you how fast your roof grows and what cleaning rhythm suits it, so it stays clean between visits rather than being rescued when it's badly overgrown.
How we work with you
Honest advice, not an upsell.
We tell you what your home actually needs, and what it doesn't. If something can wait, we'll say so. We'd rather build a long relationship than win one oversized job.
We treat the cause, not just the surface.
Most coastal problems come back because they were patched, not fixed. We work out what's actually driving the damage (salt, moisture, corrosion) and deal with that, so the repair lasts.
A proper look before any quote.
We assess your property in person before we put a number on anything. It's free, there's no obligation, and it's the only honest way to quote coastal work, because every home is exposed differently.
The coast is all we do.
We're not generalists who also do beach houses. Coastal salt, corrosion and weather are our entire focus, which is why we catch the things others miss.
Built for the coast.
Anyone can paint a wall or wash a house. The coast is different: salt gets into render, corrodes metal from the inside, and breaks down coatings from underneath, and it never stops. Treating coastal problems like inland ones is why so much work fails early.
Salt Coast exists for exactly this. We diagnose before we treat, use methods and materials suited to coastal exposure, and build ongoing maintenance relationships rather than one-off jobs. That's how a coastal home stays sound instead of lurching from one repair to the next.
Keep your home ahead of the coast, not chasing it.
You wait for paint to peel, render to bubble, metal to rust, then react to damage that's been spreading for months.
We catch it before it shows, while every fix is still small, cheap and quick, and you never lift a finger to manage it.
Fremantle based. Dawesville to Two Rocks.
We service the Western Australian coastal corridor from Dawesville in the south to Two Rocks in the north, from the beachfront to roughly 10km inland. Roof Cleaning is available across the full service area.

FAQs
How do you clean a roof without damaging it?
By matching the method to the roof material rather than blasting it with high pressure. High pressure cracks tiles, dislodges pointing and strips protective surfaces. We use methods effective on moss, lichen and grime but safe on the roof, removing the growth without the damage that reckless pressure-cleaning causes.
Why does my coastal roof grow so much moss and lichen?
Coastal humidity and salt hold moisture on the roof, and shaded, slow-drying sections plus weathered porous tiles give moss and lichen a grip. So coastal roofs green up faster and more heavily than inland ones. It's worth removing, because moss holds water against the roof, lifts tiles, and blocks gutters.
Why coastal roofs grow moss and lichen, and how to remove it safely
Is roof moss actually a problem or just ugly?
It's both. Beyond looking bad, moss holds moisture against the roof surface, works into and lifts tiles, breaks down the surface over time, and washes into gutters and downpipes and blocks them. Removing it protects the roof and the drainage, not just the appearance.
Will the moss come back after cleaning?
On the coast, yes, eventually, the humidity and salt that grew it are still there, so a cleaned roof left alone will green up again over the seasons. Keeping it in check on a regular cycle stops it re-establishing and prevents the roof returning to the heavy, tile-damaging state.
Do I need roof cleaning or a full roof restoration?
Cleaning alone is sometimes all a roof needs, and it's the cheaper option. But if the surface seal or coating has broken down, or there are cracked tiles and failed pointing, cleaning is the first step of a fuller restoration. We'll assess honestly and tell you which your roof actually needs rather than upselling.
