What's really growing on Patterson roofs
Patterson's canal-front streets around the Patterson River carry salt-tinged air off the waterways alongside moderate tree cover, and that combination settles residue and organic grime onto roofs faster than an inland suburb. Left untreated, that buildup traps moisture against tiles and shortens their working life. A professional soft-wash clears salt film, moss and grime without the high pressure that can strip a tile's protective coating or force water under capping.
Patterson's canal-front position means roofs collect salt-tinged residue from the waterways alongside normal grime, a combination that inland suburbs simply don't face.

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 Patterson
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 Patterson
- Roof size and pitch.
- The extent of salt residue and moss buildup, heavier on canal-front properties.
- Access — some rear boat access means equipment often needs to come in from the street side.
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
Patterson roof cleaning — your questions
Yes — salt-tinged air off the Patterson River waterways leaves a residue on roofs that inland suburbs don't face, and combined with moss from the area's tree cover, Patterson 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 canal-front homes given the salt exposure, compared with the 2 to 3 years typical further from the water.
