What's really growing on Chelsea roofs
Chelsea's older beach houses sit under moderate street tree cover, which is enough shade in places for moss and lichen to establish on concrete tile, particularly on the side of the roof away from the afternoon sun. Add in salt-laden air off the bay, which settles as a fine grime film on tile and colorbond alike, and Chelsea roofs pick up buildup from two directions rather than one. We treat both with a low-pressure soft wash and a biocide treatment that kills growth at the root and lifts salt film without the cracking risk that high-pressure cleaning brings to older tile. Gutters and valleys near the foreshore get particular attention, since that's where leaf litter and salt residue both collect.
Chelsea sits at the point where bayside salt exposure meets enough street tree shade for real moss growth, so a soft wash here has to handle both organic buildup and coastal grime rather than just one or the other.

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 Chelsea
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 Chelsea
- Whether the roof is concrete tile or colorbond sheeting, which need different wash methods.
- The amount of moss, lichen and salt film built up on the roof surface.
- Access on flat to gently sloping blocks near the foreshore.
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
Chelsea roof cleaning — your questions
On shaded roof faces, yes — Chelsea's moderate street tree canopy keeps some roofs damp enough for moss and lichen to take hold, especially compared to more open bayside streets further along the coast.
Yes — soft washing uses low pressure and a biocide treatment that does the cleaning chemically, which protects fragile older concrete tile from the cracking and surface damage that high-pressure washing can cause.
Most homes with moderate tree cover here do well with a clean every two to three years, though shaded roofs closer to the foreshore's tree lines may need it slightly more often.
