Roof cleaning

Professional roof cleaning for weathered Melbourne roofs

Moss, lichen and years of dirt make a sound roof look neglected and hold moisture against the tiles. Cleaning takes it back to the surface - as a job on its own, or as the first stage of restoration.

What cleaning is for

When the covering is sound but the surface is not

Melbourne roofs collect lichen, moss and grime, especially on the slopes that stay damp. That growth holds moisture against the tiles, darkens the colour and makes a structurally serviceable roof look as if it has been left. Pressure cleaning strips that back to the tile.

Cleaning is a standalone service where the roof needs nothing more than a clean. It is also the first thing that has to happen before coating - nothing bonds properly to a dirty roof - and it is a normal early stage of restoration.

Cleaning does not fix broken tiles, failed pointing or leaks. If those problems are there, they still need repairing. We will not pretend a wash is a restoration.

Is this the right work?

Signs your roof may need cleaning

These are appearance and moisture signs. They may indicate cleaning would help - they do not mean the roof is failing.

  • Moss, lichen or algae Green or grey growth sitting in the tile joints or across a whole slope, especially on the shaded side of the house.
  • A dirty, weathered surface Years of built-up dirt that will not wash off in the rain, leaving the roof darker and patchier than the rest of the house.
  • You are considering a coating A coating needs a clean tile. If colour restoration is the aim, cleaning is the preparation, not an optional extra.
  • The roof looks older than the house The walls have been painted or the garden kept up, and the covering is the element that still looks neglected.
  • Preparation for restoration Repairs and pointing are planned, and the roof needs to be taken back to a clean surface before that work continues.
The work itself

What roof cleaning involves

The work is the clean itself - plus an honest look at whether anything else is needed once the dirt is gone.

The roof is pressure cleaned to lift moss, lichen and dirt back to the tile. Access, runoff and the condition of the covering all matter: a brittle tile needs a different approach from a sound one. Gutters are cleared of what comes off the roof.

Once the surface is clean, defects are easier to see. That is useful. It is also why we will tell you if cleaning has revealed broken tiles or pointing that still needs work, rather than leaving you with a clean roof that still has a hole in it.

If you are cleaning as preparation for coating or restoration, those stages are quoted separately and only where they apply. Cleaning on its own stops at a clean, tidy roof.

  • Roof surface assessed before cleaning starts
  • Pressure cleaned back to the tile
  • Moss, lichen and dirt lifted off
  • Gutters cleared of what comes off the roof
  • Anything the clean has revealed, explained before you decide on further work

On the roof

The change is immediate from the street. What the clean cannot do is repair pointing or replace broken tiles.

How roof cleaning is done

Clean the roof, then be honest about what is left

Three steps. No coating unless you have asked for one.

01 Discuss the roof Whether you want a clean on its own, or cleaning as preparation for restoration or coating.
02 Clean the surface The roof is pressure cleaned back to the tile, and the gutters are cleared of what comes off.
03 Finished, clean roof The surface is left clean. If the work has shown repairs or pointing that still need doing, we will say so rather than ignore them.
Why Kestrel

Why choose Kestrel for roof cleaning

We clean roofs as a service, and as a stage. That means we are not trying to upsell a coating onto every wash.

Cleaning as its own job

If a clean is all the roof needs, that is the quote. Coating and restoration are separate decisions.

Ready for restoration when you are

The same team can go on to repairs, pointing and coating if the roof warrants it, without starting from scratch with someone else.

10+ years' roofing experience

Enough time on tiled roofs to know when a surface is just dirty, and when dirt is hiding a real defect.

Fully insured, family-run

Cover in place before we work on the roof. One point of contact, including on smaller cleaning jobs.

Questions about roof cleaning

If the answer you need is not here, call and ask. We would rather explain it than have you guess.

Yes. Cleaning is a standalone service as well as a stage within restoration or coating work.
No. Cleaning removes dirt and growth from the surface. It does not repair the covering. If we see damage once the roof is clean, we will tell you.
Yes. A coating needs a clean tile to bond to. Cleaning is preparation for colour restoration, not an optional extra on that kind of job.
The approach depends on the condition of the covering. Very brittle tiles need more care, and in some cases cleaning is not the right first step. That is something we assess on the roof.
We work on residential tiled and metal roofs. What is appropriate on each covering is part of the assessment - tell us what you have and we will confirm.
Growth holds moisture and makes the roof look neglected. It is not, on its own, proof that the tiles have failed. Cleaning deals with the growth; any defects still need their own work.
