What's really growing on Blackburn roofs
Under Blackburn's heavy tree canopy near the lake sanctuary, roofs stay shaded and damp, and moss, lichen and mould take hold quickly on the terracotta and concrete-tile homes here. A soft wash is the right approach: a biocide treatment kills the growth at the root, then a low-pressure wash lifts it away without stripping the tile surface. The mature trees also drop heavily into valleys and gutters, so we clear those as part of the job. High pressure has no place on Blackburn's older terracotta — it cracks fragile tiles and the moss just returns faster in this shaded setting.
Blackburn's dense tree canopy near Blackburn Lake keeps roofs shaded most of the day, so moss establishes and returns faster here than in a more open eastern suburb.

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 Blackburn
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.

Blackburn roof cleaning — your questions

Yes — it's the safe choice. Soft washing cleans at low pressure with a biocide, so Blackburn's fragile terracotta is cleaned without the cracking high pressure causes.
