What's really growing on Mordialloc roofs
Mordialloc's streets slope gently toward the foreshore and Mordialloc Creek, and the salt-laden sea air off Port Phillip Bay settles onto roofs alongside organic buildup from the suburb's moderate street tree cover. That combination of salt residue and moss can dull a roof's appearance faster than an inland suburb. A professional soft-wash clears salt film, moss, lichen and grime without the high pressure that can strip a tile's protective coating or force water under capping.
Mordialloc's bayside position means roofs collect salt residue from sea air alongside normal grime, a combination that inland suburbs simply don't face and that benefits from regular washing to prevent buildup.

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 Mordialloc
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 Mordialloc
- Roof size, pitch and the number of storeys.
- The extent of salt residue and moss buildup, heavier closer to the foreshore.
- Access — older pitched roofs near the beach need careful handling.
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
Mordialloc roof cleaning — your questions
Yes — salt-laden air off Port Phillip Bay leaves a residue on roofs that inland suburbs don't face, and combined with moss from the suburb's tree cover, Mordialloc roofs often need cleaning a little more often.
High pressure can crack tiles and strip protective coatings, so we use a soft-wash method that removes salt residue, moss and grime without damaging the roof surface.
Every 2 years is a reasonable guide for homes closer to the foreshore given the salt exposure, compared with the 2 to 3 years typical further inland.
