Roof cleaning that gets under the tiles, not just over them.

High-pressure cleaning for tile and metal roofs across Perth. Moss, lichen and years of grime come off, the valleys and lead flashings under the tiles get seen to, the gutters and downpipes get cleared, and the ground gets left like we were never there. Most roofs are done inside the day.

The job, in order

What a proper clean
covers.

Anyone can run a pressure hose over the top of a roof. These are the six steps that separate a clean from a wash.

STEP 01

Free look, and a real time estimate

We get up there, work out exactly what is involved and tell you what result the roof can realistically get to. You also get an honest time estimate, not a vague window, and a quote with the costs set out.

STEP 02

The high-pressure clean

Surface dirt, staining and biological growth come off under high pressure, using equipment and solutions chosen to clean the roof without damaging the paintwork underneath. That balance is the whole skill in this job.

STEP 03

Under the tiles as well

Valleys and lead flashings sit under the tiles, collect debris and are where a lot of roofs quietly start leaking. They get cleaned out here. Plenty of cleaners never lift a tile to look.

STEP 04

Gutters and downpipes cleared

Everything we wash off the roof has to go somewhere. Gutters and downpipes get cleared out and checked for drainage, so you are not left with the roof clean and the gutters packed solid.

STEP 05

Moss and lichen treated

Growth gets treated where it has taken hold, so it does not come straight back the next wet season. Moss holds water against the tiles, and water sitting on a roof is what actually does the damage.

STEP 06

Post-clean check and a tidy site

We walk the finished roof and tell you about anything the dirt was hiding, so a small fault does not turn into a big one. Then the ground gets cleaned up and you get straight advice on keeping the roof this way.

Straight scope

What a clean fixes.
And what it doesn't.

A clean is the cheapest thing you can do for a roof, and it is not the answer to everything. Knowing the difference saves you money either way.

A clean handles

Dirt, growth and drainage

Years of grime, staining, moss and lichen off the surface. Valleys, lead flashings, gutters and downpipes cleared so water leaves the roof the way it is meant to.

The house looks like itself again, the roof stops holding moisture against the tiles, and you can actually see the condition of the roof underneath, which is the part most people have never seen.

Broken tiles and failed pointing

Cracked and broken tiles, ridge capping where the bedding and pointing have let go, rust that has already started on metal, or a coating that has worn off entirely. Those are repairs and restoration work, and washing the roof only makes them easier to see.

If that is what we find, we will tell you at the post-clean check rather than leaving you to find out in the next storm. Cleaning and repairs can be done in the same visit.

Straight numbers

What a clean
honestly costs.

A clean on its own is the cheapest work you can put into a roof. Most Perth homes land in one honest range, and where yours sits comes down to size, pitch, access and how much growth has taken hold. If the roof needs coating as well, a clean is already step one of a full restoration, so it is worth asking for both numbers before you decide.

Clean now, or restore now?

If the coating is gone and the pointing has failed, cleaning alone buys you looks and not much else. We will say so onsite. A full restoration on a typical Perth home runs $4,000 to $9,000, and the breakdown is in our cost guide.

Fair questions

Asked every week.
Answered straight.

How much does a roof clean cost in Perth?+

A clean on its own typically runs $800 to $2,000, with size, pitch, access and the amount of growth deciding where your roof sits. You get the exact number after a free onsite look, and the full breakdown is in our cost guide.

How long does a roof clean take?+

Most roofs are done within the day. You get an accurate time estimate at the assessment rather than a guess, so you know what your day looks like before we turn up.

Will high pressure damage my tiles or the paintwork?+

Not the way we do it. Fifteen years of cleaning Perth roofs is mostly learning how much pressure a given roof can take, and choosing the method that lifts the grime without stripping the paintwork underneath.

Will the moss and lichen just grow back?+

We treat the affected areas so regrowth is slowed right down rather than starting again the next wet season. No treatment makes a roof permanently self cleaning, so a roof under trees will still want an eye kept on it.

Do you clean the gutters and downpipes too?+

Yes, and it is not an extra. Everything washed off the roof ends up in the gutters, so they get cleared and checked for drainage, and the ground gets cleaned up before we leave.

One free look.
One honest quote.

We come out, get on the roof and tell you what a clean will get it back to, what it costs, and how long it will take. If the roof needs more than a clean, we will say that too.
