What's really growing on Altona roofs
Altona's bayside roofs don't grow the heavy moss you'd see under a leafy inland canopy, but salt spray, sea air grime and the occasional lichen patch on shaded pitches still build up over time. A soft wash clears it: a biocide treatment kills any biological growth at the root, then a low-pressure wash lifts the grime and salt residue without stripping the tile surface. High pressure risks driving salt-laden moisture further into porous tiles, which is exactly the wrong outcome in a coastal setting — a gentler, thorough soft wash is the better approach here.
Altona's coastal air leaves a fine salt residue on roofs that plain rain doesn't fully wash away, so a proper soft wash clears more than just organic growth here.

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 Altona
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.

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
Altona roof cleaning — your questions
Yes — salt spray and sea air leave a residue on Altona roofs that plain rain doesn't fully clear. A soft wash lifts that along with any moss or lichen on shaded pitches.
It can force salt-laden moisture further into porous tiles, which is the opposite of what you want near the coast. A soft wash cleans thoroughly at low pressure and protects the tile surface.
We assess it at inspection, but coastal exposure means Altona roofs can benefit from cleaning a bit more often than an equivalent inland suburb.
