What's really growing on Forest Hill roofs
Forest Hill's 1960s and 1970s brick veneer homes carry mostly concrete and terracotta tile roofs, set on the fringe of the Dandenong foothills where rainfall runs higher than the Melbourne average at around 900 to 950 millimetres a year. Moderate tree cover across the older streets near Forest Hill Chase keeps some pitches shaded through the day, giving moss and lichen a steady foothold on established roofs. A soft wash treats the growth at the root with a biocide, then a low-pressure rinse lifts it away, protecting the original tile surface rather than blasting it with high pressure that can crack ageing concrete and terracotta.
Forest Hill sits on the wetter fringe toward the Dandenong foothills, so shaded roofs under moderate tree cover hold moisture longer between dry spells, giving moss more time to establish than in drier suburbs closer to the bay.

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 Forest Hill
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.

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
Forest Hill roof cleaning — your questions
With moderate tree cover here, most roofs benefit from a soft wash every two to three years. Homes on more heavily shaded blocks near mature street trees may need it a little more often to stay ahead of moss.
No — that's exactly what soft washing avoids. A biocide treatment kills the growth first, then a low-pressure rinse clears it away, so ageing tiles common on Forest Hill's 1960s and 70s homes aren't cracked or stripped.
Shade is usually the difference. A pitch facing away from the sun or overhung by a mature tree stays damp for longer after rain, and with Forest Hill's higher rainfall that gap in drying time shows up quickly.
