What's really growing on Seddon roofs
Seddon's narrow heritage streets of single-fronted Victorian and Edwardian cottages near the Maribyrnong River carry established but modest street tree cover, giving many original terracotta and slate roofs enough shade for moss and lichen to establish over more than a century. Left untreated, that growth traps moisture against tiles and shortens their remaining working life. A professional soft-wash clears moss, lichen and grime without the high pressure that can crack heritage terracotta or slate, or force water under capping.
Seddon's narrow streets and tightly spaced heritage cottages near the Maribyrnong River give many roofs partial shade for part of the day, and on century-old terracotta that shade-driven moisture drives faster moss growth.

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 Seddon
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 Seddon
- Roof size, pitch and roof material.
- The extent of moss and lichen growth on older, heritage roofs.
- Access — narrow streets and tightly spaced cottages mean ladder access from the street or laneway is common.
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
Seddon roof cleaning — your questions
The suburb's narrow, tightly spaced heritage streets near the Maribyrnong River give many roofs partial shade, and on century-old terracotta that shade-driven dampness is exactly the condition moss and lichen need to establish.
No — high pressure can crack older terracotta and slate and strip protective coatings, so we use a soft-wash method suited to heritage roof materials that removes moss and grime without damaging the surface.
Every 2 to 3 years is a reasonable guide for most Seddon cottages, with more shaded roofs generally needing it a little sooner.
