What's really growing on Berwick roofs
Berwick's roofs range from older terracotta near the historic High Street to concrete tile across the estates that have spread out since the 1990s. With around 900 to 950mm of rain a year, noticeably wetter than the Melbourne average, roofs here stay damp longer after weather rolls through, and moss and lichen build up steadily on shaded faces. Established gardens and tree cover near Wilson Botanic Park add further shade that slows drying. We use a low-pressure soft wash with a biocide treatment that kills moss and lichen at the root, rather than a high-pressure blast that can crack aged tiles and strip the surface on both old and newer roofs.
Berwick's higher rainfall band keeps roofs wetter for longer between storms, and the mix of older High Street homes and mature estate gardens means moss builds up faster here than in drier parts of Melbourne's south-east.

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 Berwick
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 Berwick
- Roof size and how heavy the moss and lichen coverage has become.
- Roof age and tile condition, from older High Street homes to newer estate roofs.
- Access across the property, including tree cover near garden beds and fence lines.
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 | ||

| 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
Berwick roof cleaning — your questions
Berwick gets noticeably more rain than much of Melbourne, so tiles stay damp for longer after each downpour. That damp environment is exactly what moss and lichen need to keep spreading, which is why a root-killing treatment lasts longer than a plain rinse.
Yes, that's the reason we soft wash rather than pressure clean. Low-pressure washing combined with a biocide treatment lifts moss and grime without the cracking or surface stripping that high-pressure water causes on older, more brittle tiles.
With moderate tree cover and higher rainfall than average, most Berwick roofs do well with a clean every two to three years. Homes closer to established gardens or with heavier shade may need it slightly more often to stay ahead of moss.
