What's really growing on Glen Iris roofs
Glen Iris's streets are dominated by Victorian, Edwardian and California bungalow homes, many still wearing their original terracotta or slate roofs under a heavy canopy of established street trees. That mature canopy is a big part of the suburb's character, but it also means constant shade and leaf litter settling on the tiles, which keeps them damp and lets moss and lichen take hold season after season. We clean with a low-pressure soft wash and a biocide treatment that kills growth at the root rather than just rinsing it off, which is essential on period terracotta and slate that a high-pressure clean would crack or wear away.
Glen Iris's heavy street tree canopy keeps period terracotta and slate roofs shaded and damp for much of the year, so moss returns quickly unless it's treated at the root with a soft wash rather than a pressure rinse.

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 Glen Iris
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 Glen Iris
- Roof size and how much moss or lichen has built up under the tree canopy.
- Roof material, since slate and older terracotta need a gentler approach than concrete tile.
- Access on period homes, including steep sections and any second storey.
The hidden cost of moss
Clean it now. Replace it never.
| Soft wash clean from $750 | Tile replacement + re-roof $8,000 – $20,000+ | |
|---|---|---|

| Preserves manufacturer tile warranty | ||
| Safe, no high-pressure tile fracturing | ||
| Completed without disrupting the household | ||

| 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
Glen Iris roof cleaning — your questions
Yes, and it's really the only sensible option. Slate is easily damaged by high pressure, so we rely on a low-pressure wash paired with a biocide to lift moss and grime chemically, protecting the slate while still getting a thorough clean.
Glen Iris's mature street trees create constant shade, and shaded tiles stay damp long after the rest of the roof has dried out. That ongoing dampness is what lets moss regrow, so we treat it at the root rather than just washing the surface.
With the heavy tree canopy typical here, most roofs need cleaning every one to two years to stay ahead of moss and leaf build-up. Roofs with less direct tree cover can often go a little longer between cleans.
