What's really growing on Highett roofs
Highett's post-war brick veneer homes carry concrete and terracotta tile roofs that are now old enough for the original factory glaze to have worn thin, leaving the surface open to moss and lichen once grime builds up. Being close to the bay, roofs here also pick up salt-laden air and windblown grit that adds to that grime layer over time. A soft wash treats the growth at the root: a biocide kills moss and lichen, then low-pressure washing lifts it away without cracking older tile the way a high-pressure blast can. We clear gutters and valleys of debris as part of the same visit and photograph any tile or pointing issues we find.
Highett's proximity to the bay means roofs collect salt-laden air alongside the usual grime, and combined with moderate garden tree cover, that's enough for real moss growth on shaded tile.

The process
How a True Roof soft wash works
2
Treat
A biocide treatment is applied so moss and lichen are killed at the root, not just wiped off the top.
3
Soft wash
Low-pressure washing lifts the dead growth and grime without driving water under the tiles or stripping the surface.
4
Clear & check
We flush the wash debris out of the gutters and do a final check so you are left with a clean roof and clear downpipes.
Roof types in Highett
Soft washing suits terracotta and concrete tile roofs and older, more fragile tiles that high pressure would damage. Colorbond and metal roofs are washed even more gently. If a roof is due for more than a clean, we will flag whether sealing or restoration is the better spend.
Our standard
Our cleaning crews are fully insured, and any repair work we recommend is backed by a 7-Year Workmanship Guarantee and a 10-Year Dulux Acratex Material Warranty.

Roof clean What affects your price
What drives the cost of cleaning in Highett
- The extent of moss, lichen and salt grime build-up on the tile.
- Roof size and pitch on standard brick veneer blocks.
- How much gutter debris needs clearing alongside the wash.
The hidden cost of moss
Clean it now. Replace it never.
| Soft wash clean from $750 | Tile replacement + re-roof $8,000 – $20,000+ | |
|---|---|---|
| Removes moss, lichen, and algae at the root | ||
| Preserves manufacturer tile warranty | ||
| Safe, no high-pressure tile fracturing | ||
| Completed without disrupting the household | ||
| Restores tile porosity and water run-off | ||
| Prevents pointing deterioration beneath the moss |
Moss is not cosmetic. It is structural damage in slow motion.
Lichen and moss anchor into tile surfaces and hold moisture against them 24 hours a day. That constant dampness accelerates freeze-thaw micro-cracking through Melbourne winters, erodes pointing mortar, and quietly voids the tile manufacturer's warranty. Most homeowners find out the hard way when tiles start fracturing or when their insurer queries maintenance records after a claim. A soft wash costs a fraction of one tile replacement row and it buys back years of tile life.

What Melbourne homeowners say
Highett roof cleaning — your questions
Yes. Salt-laden air adds to the grime layer on top of moss and lichen, so roofs here often need a proper soft wash rather than just a light rinse to fully lift the build-up.
Yes — that's why we use it. It cleans chemically at low pressure, avoiding the cracking and surface damage that high-pressure washing risks on Highett's ageing post-war tile roofs.
Most homes here do well with a clean every two to three years, though shadier roofs under established garden trees may need it closer to every two years to stay ahead of regrowth.
