What's really growing on Northcote roofs
Northcote's period terraces mostly wear original terracotta, and old, weathered tiles like these need a gentle hand. A soft wash is the right approach: a biocide treatment kills moss, lichen and mould at the root, then a low-pressure wash lifts it away without stripping the tile surface. High pressure cracks fragile terrace tiles and has no place on these roofs. Northcote's mature street trees along High Street and the side streets also drop into gutters and valleys, so we clear those as part of the job. On the concrete-tile infill homes, the same gentle method brings the colour back.
Northcote's narrow, closely built terraces mean the tight side gaps between roofs stay shaded and slow to dry, so moss and lichen build up along those edges faster than the open street-facing pitch.

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 Northcote
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 Northcote
- Whether the roof is fragile period terracotta or hardier concrete tile.
- The amount of moss and leaf debris in valleys and gutters.
- Access on narrow blocks, often tight against neighbouring walls.
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
Northcote roof cleaning — your questions
Yes — it's the safe choice. Soft washing does the work chemically at low pressure, so Northcote's fragile period terracotta is cleaned without the cracking high pressure causes.
Regularly. Northcote's tight, single-fronted terraces are common jobs for us, and we plan access and equipment around the block before the work starts.
Cleaning reveals problems like cracked tiles or failed pointing, but it doesn't repair them. If we spot something during the wash we photograph it and quote the fix separately.
